Such medications as Duromine help fight obesity, allowing you to reach your target weight and avoid many chronic diseases.

However, in addition to the main action, this appetite suppressant can cause secondary effects that may be almost invisible, unwanted, or unpleasant.

This article will discuss the side effects of taking Duromine and offer new solutions for safe weight loss management.

When you learn more about the correct and safe use of the drug, its advantages and disadvantages, you can:

  • Optimize your weight loss program.
  • Start losing weight steadily and quickly.
  • Continue treatment.
  • Prevent frequent and common side effects of Duromine, and the rare ones.
  • Control symptoms and relieve side effects.
  • Maintain normal mental and physical health.

There are three main things you should know about the side effects of Duromine diet pills or weight loss tablets containing Phentermine:

  1. They occur when you administer the drug in the therapeutic (recommended) doses.
  2. Most often, you can have them during the first week or two weeks of treatment.
  3. Most of them are dose-dependent and reversible (disappear with dose reduction).

Everyone has heard the phrase: “There are no safe drugs.” Using diet pills or any other medication always involves health risks, but it is possible to avoid them.

You can minimize the risks if you pay attention to warnings about minor and severe side effects. Read the instructions for drug interactions and avoid specific actions when using it.

Side effects of Duromine 15 mg

In terms of adverse reactions, 15 mg is the safest dose. Usually, they prescribe this dose to those in a risk group (for example, over 60 years of age) and with comorbidities or any contraindications. A gradual dose increase is acceptable if a daily dose of 15 mg does not cause adverse reactions.

Side effects of Duromine 30 mg: examples

According to clinical trials, the optimal starting dose for healthy people is one 30 mg capsule approximately every 24 hours. This dosing regimen gives a better benefit-risk ratio for most people with excess body fat.
Some people have the following Duromine (Phentermine) 30 mg side effects:

  • Feeling cheerful and energized.
  • Weakness and fatigue.
  • Burning in the digestive tract.
  • Increased blood pressure.
  • Tingling in the hands.
  • Bloating and discomfort in the abdomen.

You may have these reactions with any dose (15, 30, or 40 mg). Unfortunately, you can never say what adverse reactions you will have during treatment and how weak or strong they will be.

Correct obesity diagnostics, excluding contraindications, and consulting a doctor allow you to avoid all or most of the “dangers” of Duromine 30 mg.

Side effects of Duromine 40 mg and maximum appetite suppression

In some cases, it is necessary to increase the drug’s dosage, for example, with a plateau effect (inhibition of the weight loss process).
Increasing the dose to the maximum can lead to:

  • Restarting the fat-burning process.
  • More significant or faster weight loss.
  • Side effects of Duromine 40 mg if you have no adverse reactions to lower doses.

Despite all benefits of the appetite suppressant, you cannot deny that it can cause serious adverse reactions, especially with high doses. Besides, increasing the dose doesn’t always lead to more weight loss, but it is possible.

Duromine long-term side effects: what do we know about them

Usually, this drug does not cause problems that last for a long time. However, sometimes it leads to body reactions that last several weeks or months.

Long-term side effects of Duromine 30 mg, 15 mg, or 40 mg are as follows:

  • Increased pressure in the pulmonary artery and vessels (symptoms: shortness of breath, chest pain on exertion, brief loss of consciousness).
  • Insomnia. If you use the medicine in the afternoon or late afternoon, you may have difficulty falling and staying asleep.

You should mention Duromine long-term side effects, such as psychological or physical addiction. As a rule, you can have them with recreational use or misuse of the psychoactive substance Phentermine.

Duromine side effects after stopping treatment

Usually, the adverse reactions you can have after you stop taking this medicine disappear quickly without any medical help. However, some people may have them for several days or weeks.

After stopping Duromine, side effects may be as follows:

  • Worsened mood.
  • Excessive sweating.
  • Discomfort in the upper part of the abdomen.
  • Irritability.
  • Difficulty falling asleep.
  • Pain in muscles and joints.

To avoid these and other Duromine withdrawal symptoms, you should complete the treatment course gradually. Using the lowest dose of 15 mg at the end of treatment may be necessary. This dose may no longer suppress appetite, but it will help the body adapt.

How long do Duromine side effects last

Using appetite suppressants or any other medication always involves potential risks. If you experience adverse reactions, it does not always mean something terrible. Actually, this is evidence that the body responds to Phentermine, and the drug works. Generally, adverse reactions disappear after several days.

Duromine contraindications: when shouldn’t you take it

Don’t take medicine in the following cases:

  • Serious vascular or heart diseases.
  • Increased levels of the hormone thyroxine.
  • Pregnancy (gestation) or breastfeeding.
  • Optic nerve damage.
  • Phentermine intolerance.
  • Psychiatric disorders (for example, schizophrenia or autism).

Is Duromine bad for you

The question “Is Duromine dangerous or safe?” doesn’t have a simple answer. Human bodies are different and have varied reactions to treatment.

Duromine is a weight loss drug the TGA registered officially in Australia. What does it mean? Before going on the market, the drug has passed all the necessary checks and studies. According to clinical and experimental data, the benefits outweigh Duromine risks.

Abusing this type of drug (or combining it with psychoactive substances) involves risks, such as:

  • Anxiety.
  • Paranoia.
  • Heart problems.
  • Psychosis.
  • Mood swings.
  • Cramps.

Does Duromine cause constipation

Does Duromine make you constipated? Yes, it is possible. Many people complain about it, especially at the beginning of treatment.

You can say that a slowdown in intestinal motility or constipation is not a serious side effect. If you experience no discomfort, it’s normal to have no defecation for several days.

Can Duromine cause constipation for a long time? Yes, it can. But this probability is low enough.

If this is the case, you should take a prescription or over-the-counter laxatives. Consult your pharmacist if you are not sure what laxative to use.

Can Duromine make you constipated several times in a row? If this happens, you should consult your doctor. He will tell you what type of laxative to use this time.

The second solution is to reduce the daily dose of weight loss capsules. When there is less medication in the body, there is less risk of side effects.

The third alternative is to exercise regularly or just be more physically active. It will not only prevent constipation but will also help a weight loss program.

Also, there may be no relationship between Duromine and constipation. Some diets may cause it, for example, when the diet lacks fiber. If you have an unpleasant heaviness in the abdomen and have difficulty emptying your bowels, eat more:

  • Spinach.
  • Prunes.
  • Peas.
  • Brussels sprouts.
  • Asparagus.
  • Broccoli, etc.

In the short term, hot drinks have a stimulating effect on peristalsis and intestines.

Duromine constipation relief usually takes a few days or about a week. More complicated cases may require prescription drugs.

Some people have chronic constipation distracting them from everyday tasks. These people may start obesity treatment with a dose of 15 mg. If they have no problems with defecation, they can increase the dose.

Can Duromine cause stomach pain

The abdomen’s discomfort or pain is not the most frequent adverse reaction to Phentermine. However, you may have pain between the lower chest and groin, especially if you are on a diet that is too strict or not good for you.

You may have Duromine stomach pain because it is a great appetite suppressant. During treatment, people often forget to eat, which causes pain and other unpleasant sensations. You should remember that starvation or radical diets can lead to unpleasant complications, including those related to internal organs.

You should consult your doctor if you have worsening pain combined with liver, gallbladder, or pancreas problems.

Does Duromine cause diarrhea

You can positively answer the question, “Can Duromine cause diarrhea?” It is one of the unpleasant side effects that, in addition to discomfort, causes a significant loss of water and minerals in the body. Losing liquid leads to a short-term loss of several kilograms, which will return over time.

Does Duromine give you diarrhea after the first dose?

It is possible. Phentermine sometimes irritates the intestines or changes the concentration of intestinal bacteria. When the body and intestinal microflora adapt to the drug, frequent defecation and watery stool should disappear.

Can Duromine give you diarrhea in a severe form?

In cases of severe or prolonged diarrhea, you should seek medical help. A fever may indicate diarrhea of an infectious origin. Inform your doctor about all your symptoms. The doctor will tell you if you should use a drug for diarrhea and which one.

There may be no relationship between Duromine and diarrhea. Wanting to lose weight faster, people often drastically change their diet. Food allergies or eating foods that disrupt the digestive system can make your stool frequent and watery. In this case, it is advisable to adjust your diet.

Does Duromine make you poop more

This medicine works in the brain and does not significantly affect the digestive process. If your stool increases, probably, you eat more fiber. This indigestible part of plants slows down digestion, retains water, and “fills” the stool.

Does Duromine make you urinate more

Our body tends to excrete excess liquid through urine rather than sweat, especially during the year’s colder months. The more you drink or eat liquid foods, the more you pee.

Is Duromine a diuretic?

It is a drug for excess weight or obesity. It is not a diuretic. They don’t use it to maintain water balance, treat high blood pressure, or for other purposes.

Does Duromine make you pee more in the morning?

When fighting obesity, some people switch to liquid diets partially or wholly. If you are one of them, you may often feel the urge to pee in the morning and even wake up at night to do it. We don’t recommend going on a liquid-only diet for a long time. It is not the best strategy for long-term weight loss.

Does Duromine cause dry mouth

Yes, it is possible. It’s the most common adverse reaction that people complain about. About half of the people receiving treatment experience it.

Salivary glands located in the mouth produce oral fluid. During the day, the glands secrete about 1.5 liters of saliva consisting of water, proteins, salts, trace elements, and other substances.

When stimulating the brain and suppressing appetite, the drug can partially suppress the function of the salivary glands. Duromine dry mouth is due to reduced saliva production.

Also, you may have Duromine bad breath. It may be the result of the dry tongue and the subsequent cracks and plaque on it.

Tips for maintaining the proper moisture level in your mouth:

  • Drink more water.
  • Breathe through the nose.
  • Don’t smoke or reduce the number of cigarettes smoked.
  • Use chewing gums and sugar-free lollipops.
  • Use air humidifiers.

Does Duromine make you thirsty

Many people ask: “Why does Duromine make me thirsty?”. The thing is that drugs of this type suppress the production of saliva in the mouth, which makes us drink more water.

Important information! If you drink a lot of water and don’t forget to watch the amount and calorie content of food, you will lose weight faster. Water has no calories, but when it is in the stomach, it makes you feel full.

Can Duromine cause nausea

About 1 in 6 people complain about this side effect. Usually, nausea doesn’t appear spontaneously. Various smells, tastes, headaches, emotional stress, etc., can cause it. Unpleasant sensations in the throat or stomach can lead to vomiting.

If you experience Duromine nausea and vomiting, you should eat before taking the drug. Reducing the daily dose may be an alternative.

Does Duromine cause mouth ulcers

Today there is no proven relationship between Duromine and mouth ulcers. On the other hand, a severe form of such side effect as dry mouth may lead to irritation of the oral cavity tissues and ulcers.

Can Duromine cause hair loss

During post-marketing studies, there were several cases of Duromine and hair loss. Considering this information, you can assume that this is a very rare side effect not even mentioned in the package leaflet for this medicine.

That’s why it is very difficult to answer the question “Does Duromine cause hair loss?” in the affirmative. For example, your hair may begin to thin or break due to a change in your diet and a limit on the intake of the required amount of macro- or micronutrients.

It is safe to say that alopecia is one of the adverse effects of people taking Qsymia. This drug contains 2 ingredients, Phentermine and Topiramate, and it is the second substance that causes alopecia.

Can Duromine cause headaches

Clinical studies record this side effect but didn’t prove a direct relationship between Duromine and headaches. It may have the following reasons:

  • Dehydration.
  • Starvation.
  • Insomnia.
  • Hormonal changes.
  • Hypertension.

Does Duromine cause headaches of repeated nature? Yes, it does, especially at the beginning of treatment.

Here’s what you can do to avoid them or decrease their severity:

  • Eat oftener so that your brain receives nutrients from healthy food.
  • Try to rest and not be nervous.
  • Walk outdoors.
  • Start using vitamin supplements as advised by your doctor.
  • Try over-the-counter pain killers.

If nothing helps, consult your doctor on using prescription pain medications.

Can Duromine cause high blood pressure

This drug may cause adverse events related to blood vessels or heart function. If you mean the increased blood pressure, few people complain about it.

Does Duromine cause high blood pressure during the whole treatment course?

Yes, it is possible. And usually, people tolerate it easily. However, you should understand the benefits of treatment not only in terms of body shaping. Even slight weight loss reduces the risk of many heart or vascular diseases, such as slowing or halting the progression of hypertension. If you have pressure problems, check it daily to keep track of changes.

Can you take Duromine with high blood pressure

Yes, you can do it. However, there are a few restrictions, which we will discuss below.

First, if you study the indications carefully, you can see the following:

THEY WON’T PRESCRIBE treatment if you don’t have the diagnosis of class 1 to 3 obesity (BMI ≥ 30).
THEY CAN PRESCRIBE this drug if you don’t have the diagnosis of obesity, but your weight is above the normal weight range (BMI ≥ 25), and you HAVE HYPERTENSION (controlled).

Learn more about BMI.

Important information! Duromine and high blood pressure you can’t control is a contraindication. If the pressure problem is not very serious, you can start the treatment course, but first, you should consult a doctor.

Many obese people ask a natural question: can you take Duromine while on blood pressure medication? Certainly, the combination of these drugs is not a contraindication, but interactions are possible, usually not very serious. The doctor will tell you what drug for hypertension is best to use and whether you should adjust the standard dosage.

Does Duromine thin your blood

Many obese people have vascular problems and worry about heart attack, stroke, and other issues. No wonder they ask the question: is Duromine a blood thinner?

As mentioned above, this drug has an effect on the central nervous system and is an appetite suppressant. It is not one of the drugs known as blood thinners (antiaggregants or anticoagulants).

Can Duromine cause blood clots

Currently, there are no reports of its effect on plaque formation or prevention of their formation. However, physical activity, a healthy diet low in unhealthy fats, and losing excess fat prevent the formation of:

  • Cholesterol plaques.
  • Blood clots.

Can Duromine cause a heart attack

We have carefully reviewed the information provided by the Therapeutic Goods Administration from Australia and found no mention of this side effect.

So, there is no reason to talk about a relationship between Duromine and heart attack, although they rarely detected this relationship during the use of other anorexigenic drugs.

Can Duromine increase heart rate

Yes, it is possible. There is a relationship between Duromine and heart rate. It is important to say that it is the effect mentioned concerning the mechanism of action of the CNS stimulant. So, they don’t always classify it as a side effect.

Does Duromine cause sweating

This medicine:

  • improves energy level.
  • increases body temperature.

Because of these effects, the sweat glands have to speed up their work for better body temperature control.

Sweating on Duromine is reported by many women of middle age, especially in the first month of treatment. It can be a little unpleasant but sweating due to burning calories or fat speeds up the process of losing weight.

Duromine skin side effects

Treatment with Duromine and side effects on the skin affect less than 1 in 100 people who start treatment. The low frequency of these adverse events is due to the fact that Phentermine mainly affects the central nervous system and organs of the cardiovascular system.

Can Duromine cause acne

You can give a negative answer to the question, “Does Duromine cause acne?”. In any case, there is no direct relationship. It’s the opposite. Obesity and related diseases cause acne and worsen it. Correct and gradual weight loss reduces any negative effects on the skin.

To avoid skin problems, it is necessary to reduce the consumption of foods with a high glycemic index and ensure that micronutrient deficiencies do not appear in the body. If you get more physically active, sweat and dirt should not stay on your skin for long.

Can Duromine cause rash

Yes, it is possible. Rash because of Duromine is a rare and severe side effect. If you have allergic reactions to Duromine, such as:

  • skin rash,
  • swollen face,
  • burning skin,
  • breathing problems,

you should inform your doctor or pharmacist as soon as possible.

Does Duromine affect fertility

A growing number of people fight obesity, including those who still have no children or those who think about increasing their family. So, it is not surprising that they ask, “Can Duromine affect fertility, and if so, how?”.

Phentermine doesn’t affect the biological aspects necessary to conceive a child, such as:

  • Spermatogenesis.
  • Motility of spermatozoids.
  • Egg production.
  • Ovulation and so on.

So, the drug does not reduce the chances of conception.

Does Duromine increase fertility?

Appetite suppressants are not infertility drugs. But in the case of people who successfully reduce their body fat percentage, hormonal balance improves. It significantly increases the chance of successful conception for both men and women.

Can Duromine cause miscarriage

Pregnant women didn’t participate in clinical trials, so it is difficult to answer this question.

No one should take anorectics during pregnancy, and not just because they are potent CNS stimulants. During pregnancy, you shouldn’t reduce the amount of fat in the body, even if it is excessive, resorting to anorectics.

Does Duromine affect your period

Women got used to the predictability of changes that regularly happen in the reproductive system, and usually, they worry about early or late menstrual cycles. So, they may ask the question, “Can Duromine affect your period?”.

The menstrual cycle also depends on the processes taking place in the ovary. Anorectics don’t significantly affect the reproductive system, but sometimes women still feel changes. As a rule, there is no direct relationship between the side effects of Duromine and the menstrual cycle symptoms. During therapy, menstrual bleeding may start a little earlier or later, be a little heavier or lighter. Still, all this is usually the result of weight loss and hormonal changes related to it, as well as a consequence of stress.

You can give a positive answer to the question, “Does Duromine affect your period?”. If you consider this influence in the medium or long term, it is rather positive than negative. Reducing the amount of fat tissue improves the function of the reproductive system and hormonal levels.

Can Duromine stop your period

The official information provided by the Therapeutic Goods Administration doesn’t mention this side effect. However, it is possible for the following reasons:

  • Strong stress.
  • Pregnancy.
  • Menopause.
  • Hormonal imbalance.
  • Excessive exercise.

Can Duromine cause thrush

Fungal diseases of the genital organs usually are due to:

  • Decreased immunity.
  • Failure to follow hygiene rules.
  • Use of antibiotics.

Appetite suppressants don’t cause thrush, but they fight one of the causes of vaginal fungal infections – obesity.

Duromine and PCOS

Unfortunately, there is no cure for PCOS. And with this disease, it is easy to gain weight and difficult to lose it.

There are several studies supporting the effectiveness of Duromine for PCOS. You should be aware that this is a symptomatic treatment that helps mitigate the effects of this disease but doesn’t cure it. By successfully fighting obesity, you reduce excess fat, increasing the chances of getting pregnant.

Duromine and ADHD

If you have ADHD, your doctor should solve the issue of Duromine and ADHD.

It is important to understand that they don’t prescribe Duromine for children under twelve. Moreover, it may interact with sympathomimetics, including those used to treat ADHD (such as amphetamine).

Does Duromine help with ADHD

They use different types of stimulants to treat ADHD. Strong appetite suppressants are also stimulants. Consequently, people ask a logical question: “Does Duromine work for ADHD?”

Knowing its strong affinity to amphetamines, they use Duromine for ADHD, but it isn’t an approved indication. Considering the short duration of use of diet capsules (several weeks), it is difficult to say about the effectiveness of this method for ADHD treatment.

Can diabetics take Duromine

Yes, they can do it, although not all of them.

  • It is important to understand that diabetics can use Duromine if their BMI is ≥ 25 and they have no contraindications.
  • If you don’t have diabetes or some other problems related to excess body fat, you can use this drug only if you have a BMI ≥ 30 (a BMI indicating obesity).

IMPORTANT INFORMATION! During the intake of Duromine and diabetes treatment, you usually reduce the dosage and/or frequency of using hypoglycemic drugs.

Duromine and mental health

Appetite suppressants such as CNS stimulants can affect how we feel, think, and act. Sometimes these medications cause mental health problems, especially during the first week or two weeks of treatment. As a rule, psychiatric side effects are not severe and subside over time.

Can Duromine cause depression

Yes, it is possible. They classify depression as a rare side effect. During obesity treatment, depression is also dangerous because it can stimulate appetite, increase interest in food and cause weight gain.

Does Duromine cause depression of a severe form?

Yes, this adverse reaction is possible, but it is quite rare. If your mental condition is such that you cannot work, study and lead a normal life, you should seek help from a doctor. He will advise how to deal with this problem.

IMPORTANT INFORMATION! Medications to treat symptoms of depression may interact with Duromine.

Can Duromine make you depressed when abused?

They recommend using this drug for a limited time, usually no more than 3 months. Prolonged treatment, especially if you exceed recommended doses and suddenly stop using the anorectic, may cause depression and other psychological side effects.

Does Duromine make you depressed after the first dose?

There is no mention of this body reaction. At the very beginning of treatment, you use low doses of the appetite suppressant, and the body concentration of Phentermine isn’t high.

Can Duromine cause mood swings

Yes, it is possible. Usually, it is due to hormonal changes caused by a decrease in body fat percentage. Emotional instability and mood swings disappear after the normalization of the hormonal background. Regular exercise and a balanced diet will help you and your brain function rationally.

Can Duromine cause anxiety

Clinical studies have recorded this adverse reaction but have not found a direct relationship between Duromine and anxiety. It may be a result of stress lifestyle changes.

In this case, the following can be helpful for you:

  • Listening to soothing music.
  • Regular sleep.
  • New hobbies.
  • Food supplements and/or vitamins.
  • Psychological therapy.
  • Eliminating stressors.

Can Duromine make you angry

This type of side effects is possible, although the Therapeutic Goods Administration doesn’t mention it. As a rule, people with a short temper have anger control problems.

Even if you are the calmest and most patient person in the world, sooner or later, you will encounter something that can throw you off balance. For example, getting angry is okay when you witness an injustice. However, it can be a problem when your reaction causes harm to others.

Does Duromine make you angry if you don’t lose weight?

After a few weeks or months of treatment, many people see no progress in their weight loss program. It can be very difficult to stay calm when you can’t get rid of stubborn fat.

Here are some simple ways to control anger or irritation:

  • Deep abdominal breaths.
  • Visualization of something you like.
  • Walking in the open air.
  • Yoga.
  • Finding alternative weight loss methods.
  • Activities filling you with positive energy.

Does Duromine increase libido

Obesity and the treatment of this disease can affect the sexual activity and reproductive capabilities of people. That’s why men and women often ask the question: “Does Duromine affect libido?”.

There are 2 important aspects you should understand:

  • Few people have Duromine sex drive decrease. It is a temporary side effect that disappears after several days (weeks) or at the end of therapy.
  • Successfully fighting obesity has a positive effect on self-esteem, solves many sexual problems, and relieves tension in sexual life.

Does Duromine make you horny?

Phentermine is a substance that can increase the release of neurotransmitters, increase energy levels and increase sex hormones due to lifestyle changes. There is an assumption that all this increases sexual arousal and sensitivity.

Surely, everyone doesn’t have the above effects. If it were so, this drug would have a new indication.

Can Duromine cause erectile dysfunction

Yes, it is possible, but you shouldn’t panic. The good news is that erectile dysfunction is a temporary effect.

Let your body get used to the medicine. Remember that the right lifestyle changes tone the cardiovascular system and are good for improving sexual function.

Does Duromine increase metabolic rate

Clearly, there is a strong relationship between calorie-burning rate and weight loss. The faster fat is burned, the easier it is to reduce your BMI.

You can answer the question “Does Duromine boost and speed up your metabolism” this way.

  • On the one hand, it slightly increases energy levels (not metabolism), but this effect is not the main one. The drug causes weight loss by reducing appetite.
  • On the other hand, lifestyle changes speed up the biochemical processes related to the breakdown of fats and the foods we eat.

The question remains, “Does Duromine increase your metabolism” without exercise, and the answer is NO.

Maintaining and/or building muscle is the main key to weight loss. If you lose muscle mass, it will eventually slow down your metabolism.

You can exercise in different ways, but in any case, the muscles will burn many calories. The most interesting thing is that the process of burning calories will continue for several hours after training.


Have you discovered Duromine (Phentermine) and started enjoying its amazing weight loss effects? Be sure that you are on the right path you should follow to the end. If you have side effects, it is not a reason to panic or stop treatment.

As you can see, various physical health and well-being problems can happen during treatment. So, Duromine’s side effect awareness and relief can be very important for your recovery and well-being. If you notice any Duromine long term side effects or suspect that the negative influence persists longer than you thought, consult with your doctor.
