Your Medication Phentermine

Phentermine is also known by the brand name: Adipex P.

Phentermine comes in 15, 30, 37.5 mg capsules, and 37.5 mg tablets and should be stored at room temperature in a dry place.

Phentermine is most commonly used to treat obesity. No matter what your doctor has you taking it for, phentermine is taken by mouth once daily. Take all forms before breakfast or 1 to 2 hours after breakfast. If you miss a dose, take the missed dose as soon as you think about it. If it is close to time for your next dose, skip the missed dose and resume your normal dosing schedule. Do not take 2 doses at the same time or extra doses.

Some common side effects with phentermine include high blood pressure, headache, dizziness, restlessness, and increased heart rate.
Some less common side effects include constipation, unpleasant taste, dry mouth and unable to get to sleep at night.

Do not take phentermine if you have a history of cardiovascular disease, hyperthyroidism, glaucoma, a history of drug abuse, or are pregnant or breastfeeding.
