As you need a doctor’s prescription in order to take phentermine, you’ll need to talk to your doctor about any medical conditions you may currently have or have suffered from.

If you have any of the following conditions or have previously suffered from them, please tell your doctor:

– Family History of Mental Illness or Mental Illness – you’re more likely to experience depression or other mental illnesses.

Phentermine Contraindications

Certain situations make taking phentermine harmful or dangerous. If any of the following apply to you, you should not take phentermine.

– Alcohol

When it comes to drinking alcohol, you should abstain from doing so while taking phentermine or any other appetite suppressants. Alcohol increases the side effect of dizziness. Do not drink while taking phentermine.

– Diabetes

Phentermine can also cause troubles for those with diabetes. Keep an eye on your blood sugar levels. If there is a significant change, contact your doctor immediately.

– Hyperthyroidism (over-active thyroid)

Phentermine may cause your condition to worsen. Appetite suppressants including phentermine pose a serious risk to those with this condition.

– Kidney disease

Those with kidney disease are at risks for serious side effects while taking phentermine. Because it is in higher concentrations in the blood, phentermine should not be taken by those with kidney disease.

– Driving and hazardous work

Driving as well as hazardous lines of work (such as construction where one operates heavy machinery) is not recommended while on phentermine. It leads to sensations of false well-being, dizziness, lightheadedness, drowsiness, or being less alert than usual. Phentermine or other appetite suppressants should be taken first with caution to see how they affect each individual person.

– Surgery, dental treatment, or emergency treatment

Before scheduling any surgery for dental issues or other, you should let the oral surgeon, dentist, and doctor know about your prescription to phentermine. It poses a risk in some cases for serious side effects.
