What Is Phentermine?

Precautions To Remember

Phentermine should not be taken by patients who have high blood pressure or cardiovascular disease, and it is not appropriate for individuals with glaucoma or an overactive thyroid gland. Patients who are pregnant should not use this medicine since weight loss during pregnancy, even in individuals who are overweight, may be harmful to the unborn baby. This medication has the potential to pass into breast milk, and patients who are breastfeeding should not take it. Since phentermine may lead to dependency, patients with a history of substance use disorders should use an alternative weight loss medication instead.

Before phentermine is prescribed, patients should let their doctor know about any history of kidney disease, blood pressure issues, or heart valve disorders, as this medication may not be safe for patients with these health concerns. Diabetes patients should ask their doctor about adjusting the dose of their diabetes medications during their treatment with phentermine. This medication needs to be taken around the same time each day. Patients who take it three times per day should take each dose roughly thirty minutes before breakfast, lunch, and dinner, and individuals who take it once a day should take their dose either before breakfast or one to two hours after breakfast. If the patient forgets to take a dose, they should skip the dose for that day if it is late in the afternoon or evening. Taking two doses at one time could cause serious side effects, and it may be fatal.
