Here is an important rule that all those who want to lose weight on the drug should learn: Phentermine dosage and Phentermine dose are not the same.

In the first case, it is a daily dosing schedule prescribed by the doctor, and in the second case, it is the amount of the drug taken at a time.

We will discuss the Phentermine dosage: what to do if you take too much of the drug, how long you can take it and what the consequences may be.

Is Phentermine dosage of 75 mg prescribed

Phentermine is available in 8 mg and 37.5 mg tablets and 15 mg, 30 mg and 37.5 mg capsules. The reason is that the lowest effective dose of the drug is 4 mg, and the highest one is 37.5 mg.

However, if there is no visible effect, can you increase the Phentermine dosage to 75 mg? You shouldn’t decide on an additional drug intake on your own. It is for a doctor to make any changes in the dosage.

Specifics of the chemical structure of Phentermine

Most diet pills available in the USA and Latin America contain phentermine.

Phentermine hydrochloride is the main element in the drug production. The chemical structure of Phentermine is similar to that of amphetamine, but the formula is different: C10-H15-N, with H replaced by CH3.

Risk of Phentermine abuse

Surely, there is a risk of Phentermine abuse. As a rule, it happens by negligence. For example, you forgot that you already took the drug and used it again, or you wanted a quick result and increased the dose on your own.

You should remember that exceeding the dosage will not accelerate the effect, and extra kilograms will not disappear instantly! To avoid problems, set the alarm for every day at the same time to make sure you do not exceed the acceptable dose.

Phentermine right dosage

What to do if I took 2 Phentermine by mistake

If you took 2 Phentermine by mistake but did not exceed the maximum acceptable dosage of 37.5 mg, it’s okay!

However, a dose of 75 mg a day can be dangerous. Don’t exceed it and follow the dosing regimen prescribed by your doctor. Taking more Phentermine will lead to overdose and dangerous side effects.

What is the risk of Phentermine overdose?

Phentermine overdose is possible in case of exceeding the indicated dosage at a time or within 24 hours. A significant increase in the drug in the body can be fatal.

Possible overdose depends not only on the amount of Phentermine but also on other drugs that do not mix well with each other. The number of diet pills that can lead to an overdose also depends on the body’s characteristics.

To avoid overdose:

  • inform your doctor about all medications you take;
  • don’t self-medicate, and don’t buy pills without consulting your doctor or pharmacist;
  • don’t drink alcohol or smoke while taking Phentermine;
  • cut down on caffeine.

How long does it take to overdose on Phentermine

Interestingly, overdose can be acute (sudden) and chronic. If acute overdose is a result of a single use of the drug in large quantities, chronic one is a result of a cumulative effect.

How long does it take to overdose on Phentermine in chronic cases? It depends on how much you increase (consciously or with other drugs) the amount of phentermine in the body. If you see the symptoms of overdose, contact your doctor immediately.

How much Phentermine is fatal

As you can see, Phentermine overdose is very dangerous. To avoid adverse effects, you should know how much Phentermine is fatal. Using a dose greater than 75 mg is potentially fatal. It is especially critical to use this drug with other medicines enhancing the effect of Phentermine or having similar ingredients.

Is long-term use of Phentermine possible

Even long-term use of phentermine can lead to overdose. Manufacturers recommend using the drug for three months or twelve weeks. During this time, you can use Phentermine at any permitted dosage.

There were no studies on a longer use of the drug. However, in 2012, the Food and Drug Administration (FDA) released a new list of medicines of long-term use approved for obesity treatment, including a phentermine-based drug. The National Institutes of Health (NIH) published the information.

What happens if you take Phentermine longer than 3 months

Do you want to know if you can take Phentermine longer than 3 months but can’t find the information? The thing is that there are no official prescriptions for long use of Phentermine since the drug is for short-term treatment. For individuals at low risk of cardiovascular disease, long-term drug use leads to greater weight loss without side effects.

What can I do to make Phentermine work more effectively

Since the drug is primarily for the short-term treatment of obesity, many prefer to start using a dosage of 37.5 mg. Some believe that increasing the dosage will help improve future weight loss results.

Because of biological differences, increasing the dose of Phentermine may increase weight loss, but not in all cases. You can find out how to make Phentermine work more effectively differently if you don’t want to exceed the permitted dose of the drug.

It requires:

  • balanced diet;
  • exercise;
  • following the daily routine;
  • getting enough sleep.

When combined with the proper lifestyle, Phentermine will allow you to get rid of unwanted kilograms faster and improve your health.

Conclusion

It is essential to use Phentermine according to the recommended dosage. Failure to follow the doctor’s prescriptions may adversely affect your health and lead to overdose. If you want to achieve a better result, it is not necessary to increase the dose of the drug, it is enough to acquire healthy habits.

It is possible to continue taking Phentermine for a longer time, but you should discuss any change in the obesity treatment with your doctor.
