Many people will recognize the drug Adipex by its generic drug name phentermine. Phentermine was one of the two drugs found in the Phen-Fen combination that was popular in the mid-nineties. While its counterpart, fenfluramine, was pulled from the market due to its causation of dangerous heart valve abnormalities, phentermine (Adipex) remains on the market. There is a great deal of controversy surrounding the diet medication due to its dangerous side effects and potential for abuse.
Uses
The Mayo Clinic tells us that Adipex, used in combination with diet and exercise, is an amphetamine-like drug that helps suppress appetite and promote a feeling of fullness. Adipex is intended for people who are significantly overweight and is approved by the U.S. Food and Drug Administration only for short-term use--approximately 12 weeks.
Administration
According to the National Institutes of Health publication Medline Plus, Adipex can be prescribed in tablets or extended release capsules. It can be taken as a single dose in the morning or three times a day before meals. Phentermine should be taken whole; do not chew, crush or break open the capsules. Doctors may initially start a patient on a lower dose, increasing the dosage gradually to avoid side effects or building up a tolerance to the medication. Take the medication exactly as prescribed. There is a potential for addiction.
Side Effects
The most common side effects of Adipex include dry mouth, an unpleasant taste, diarrhea, constipation and vomiting. Patients should consult their doctor immediately if they notice heart palpitations, insomnia, increased blood pressure, dizziness, tremors, shortness of breath or swelling of the legs or ankles. If you experience symptoms of hives, difficulty breathing or swelling of the lips, face, tongue or throat you should seek emergency help immediately.
Special Precautions
Always tell your doctor if you are taking any medications, including over-the-counter medications, vitamin and herbal supplements, as they may interact dangerously with Adipex. Avoid taking Adipex if you are taking a MAO Inhibitor. Phentermine can make people feel sleepy so it is important to avoid driving or operating heavy machinery until you know how you will react to the medication. Make sure that you inform your health care provider of any heart problems or if you have high blood pressure, atherosclerosis (arterial plaque buildup), hyperthyroidism or diabetes. Caffeine when used in conjunction with Adipex can cause a dangerous rise in blood pressure.
Considerations
According to Dr. Donald Hensrud of the Mayo Clinic, statistics show that once you stop taking Adipex you are likely to gain the weight back. You are more likely to achieve long-term weight loss success if you focus on diet and exercise rather than relying on prescription medications.
