Phentermine tablets are prescription medicines used for short-term weight loss as part of a broader weight-management plan (diet, exercise, and behavior changes). They are stimulant-like drugs that suppress appetite by acting on the central nervous system.
Key points
- What they are: Phentermine hydrochloride tablets. Brand names you might see include Adipex-P (often 37.5 mg), Lomaira (8 mg), and various generics. Doses can be in several strengths (commonly 8 mg, 15 mg, 30 mg, 37.5 mg), depending on the country and product.
- How they’re used: Typically prescribed for short-term use (often up to about 12 weeks) to help with weight loss in conjunction with diet and exercise. Not for long-term use as a sole solution.
- Who should not use them: People with uncontrolled high blood pressure or heart disease, severe coronary artery disease, glaucoma, hyperthyroidism, a history of substance abuse, or those who are pregnant or breastfeeding. Also generally avoided with MAO inhibitors or other stimulant medications.
- Common side effects: Dry mouth, insomnia, increased heart rate or blood pressure, nervousness, dizziness, constipation, or upset stomach. Less commonly, mood changes or more serious cardiovascular symptoms.
- Important safety notes: They can raise blood pressure and heart rate and may be habit-forming. Do not take with other stimulants or MAO inhibitors. Avoid alcohol. If you have chest pain, severe headaches, fainting, or signs of an allergic reaction, seek medical care.
- Pregnancy and contraception: Phentermine is usually not recommended in pregnancy; effective contraception should be used while taking it.
