Is Adipex Effective for Weight Loss?

Adipex, an appetite suppressant, is the brand name of the prescription weight loss drug phentermine. It is intended for those who have a body mass index of 27 or more who also have health problems associated with their obesity, or those who have a body mass index of 30 or more without any other health conditions.

Time Frame

Adipex is approved for short-term use of up to 12 weeks, but PubMed Health notes that most people only take this drug for three to six weeks. The exact length of time you will take Adipex depends on how much weight you have to lose and how your body responds to this medication. Most doctors will prescribe Adipex for the shortest time possible, as it is addictive due to amphetamine-like properties. After a short period of time, your body will adjust to the appetite suppressant and it won't be effective anymore, so taking Adipex for longer than necessary won't net any additional weight loss.

Types

Adipex is available in two forms: tablets and extended release capsules. The tablets are taken three times per day. Each pill is taken approximately 30 minutes before a meal. The extended release capsules are taken once daily -- usually 30 minutes to two hours before breakfast. Taking more Adipex than prescribed each day won't increase your weight loss and may cause you to overdose.

Considerations

In order to get the best results from Adipex, you have to eat a low-calorie, balanced diet. When your doctor prescribes Adipex, he will give you a diet plan to follow to ensure that you lose as much weight as possible during the short period you can take Adipex. Your doctor will also give you and exercise program to follow. Depending on your physical abilities, this program may include up to 90 minutes of exercise per day. It is important to follow the program so that you can burn fat and gain muscle while you are taking Adipex.

Warning

Although Adipex is an effective weight loss aid, it isn't appropriate for everyone. People with heart disease, coronary artery disease, hyperthyroidism, glaucoma or uncontrolled high blood pressure shouldn't take Adipex. Those who have a history of substance abuse and those who are taking other weight loss medications or supplements can't take Adipex. Even if you don't suffer from any of these conditions, you may still experience some side effects while you take Adipex. These include dry mouth, altered taste, sleeplessness, headaches, dizziness and gastrointestinal upset. These, and any other symptoms you experience, should be reported to your doctor immediately.
