When you take any drugs, you read the leaflet, right? You will never take 5 tablets of Rizatriptan to have a better effect on migraine because you read about the drug’s possible negative effects. Each potent drug has its adverse reactions and contradictions. The same is with weight-loss medication. Phentermine adverse effects are written in the drug’s leaflet as well.
Although not all the users experience negative side effects of Phentermine, you’d better know the enemy by sight.
In this article, we will answer all the questions about this diet pill: Phentermine side effects, possible risks of Phentermine, and how to cope with it.

Long-term Side Effects Of Phentermine

If you are afraid of taking diet pills because of the long-term side effects of Phentermine, just take a deep breath:

  1. Not all the severe adverse effects last forever.
  2. Many people don’t experience adverse reactions for the whole treatment period. Maybe you will also be a lucky man.
  3. The same negative impact may last for one for 3 months, for another – a few days.
  4. Ask your doctor who knows your medical conditions about dealing with adverse effects.

However, if you experience severe side effects on Phentermine for a long time, contact your doctor. Maybe you need to change the dosage or stop taking weight-loss pills.
Let’s describe the most common and rare, short-term and long-term Phentermine adverse reactions.

Phentermine 30 mg side effects

Any medicine can have adverse reactions. However, for many people, Phentermine, Phentermine HCL, and Phentermine Juno Er 30mg side effects are either minor or non-existent.

These adverse reactions may include:

  • Dizziness or headache;
  • Nervous tension and agitation;
  • Diarrhea or constipation;
  • Dry mouth;
  • Sleep disorders;
  • Violation of taste perception;
  • Decreased sex drive;
  • Anxiety.

This list of possible adverse effects is not exhaustive. If you have any questions about side effects, don’t hesitate to contact your doctor.

Side effects of Phentermine 37.5 mg

Adverse reactions of Phentermine 37.5 are the same as Phentermine Hydrochloride side effects. Phentermine Hydrochloride is the hydrochloride salt form of Phentermine.

The most common side effects of Phentermine 37.5 mg are:

  • dry mouth;

All the adverse reactions of this dosage may be less than 40 mg but stronger than 15 or 30 mg.

Phentermine side effects

Phentermine 40 mg side effects

Phentermine 40 mg side effects are quite the same as other dosages. However, it’s the most potent dose of the drug, the effectiveness is higher, and the risk of adverse effects is pretty higher. But again, some people feel ok on this dosage. At the same time, other users may experience severe adverse reactions and need to decrease the dose to the lower one.

Phentermine side effects dangers

Is Phentermine bad for you? Unless you don’t experience severe side effects, there is no danger for you.
Call your doctor or seek medical help if you have any of the following signs or symptoms that may be associated with severe Phentermine side effects dangers:

  • Signs of an allergic reaction such as rash, hives, itching, red and swollen skin with blisters or peeling, possibly in combination with fever, wheezing, tightness in the chest or throat, difficulty breathing, swallowing or speaking, unusual hoarseness, swelling in the mouth, face, lips, tongue or throat;
  • Signs of high blood pressure include a severe headache, dizziness, loss of consciousness, or blurred vision;
  • Pain or pressure in the chest;
  • Movement disorders;
  • Mood changes;
  • Shiver;
  • Dyspnea;
  • Some people who take this type of drug may develop heart valve disease. Call your doctor immediately if you have dizziness, fatigue, or weakness that does not go away, tachycardia or palpitations, swelling of the arms and legs, or difficulty breathing.

Phentermine side effects in females

Phentermine side effects in females are more about hormones. The most reported side effect is menstrual cycle changes.
Menstrual irregularities are not a common side effect. The manufacturer in the leaflet does not mention it. However, some women experience some changes in their period. Among listed menstrual cycle changes are:

  • Missed periods;
  • Late or early periods;
  • PMS symptoms are worse than before;
  • Bleeding;
  • Light or heavy periods;
  • Postmenopausal issues.

It doesn’t mean you will undoubtedly have some “female” side effects. But forewarned is forearmed.

Important! Sometimes it’s not Phentermine to blame.
Some people who want to lose weight stop eating fats, thinking they are bad for their weight loss. It’s a common mistake!
Deficiency in using healthy fats leads to problems synthesising sex hormones, decreased libido, changes in the menstrual cycle, depression and irritability.

Phentermine breakthrough bleeding

Phentermine processes estrogen faster if you are on birth control. Taking Phentermine with birth control medicine may cause breakthrough bleeding. Phentermine breakthrough bleeding is a rare adverse reaction, but you’d better think twice or ask your doctor before taking these drugs together.

However, high heart rate often happens on Phentermine.

How to lower heart rate while on Phentermine?

Phentermine and high heart rate are almost synonyms. It is a pervasive side effect. The amount of your heart rate also depends on the dosage and age.
What your maximum heart rate is? Use this formula to know: 220 minus your age. For example, you are 40 years old: 220-40=180. Thus, everything more than 180 is a high heart rate for you.
