Obesity is one of the largest health concerns affecting Americans. Although most practitioners agree that exercise and dietary changes are the best way to lose weight, there are a number of medications available to help you. Two of those medications are Adipex, which is available only by prescription, and Alli, which can be purchased over the counter. There is no evidence of drug interactions between the two medications but both drugs may cause a number of side effects and should not be combined without professional advice. Your doctor or health professional should help you decide what weight loss regimen may be right for you.
About Adipex
Adipex is a brand name of the generic drug, phentermine. It is an amphetamine-type appetite suppressant that has been used for many years under other brand names including Ionamin and Fastin along with Adipex, and is available as a generic prescription. It is only approved for short-term use for appetite control. It is a controlled substance and may require a special prescription written by your doctor because it may be addictive or abused.
Side Effects
As Adipex is a mild amphetamine, it may cause a number of side effects including nervousness, rapid heart rate and insomnia. It is also considered to be mildly addictive and has potential for abuse. Side effects will likely be worse if you take more than the prescribed dose. It may decrease the effectiveness of some medications such as high blood pressure and heart medications and you should not take it if you have uncontrolled high blood pressure or other cardiac conditions. Talk to your doctor about all of your medical conditions and medications you are taking.
About Alli
Alli is the over-the-counter strength weight loss medication containing the generic drug, orlistat. Orlistat is also available in a prescription-strength medication Xenical. Alli works to promote weight loss by binding up to 30 percent of the fat in the food that you eat. Instructions for use of Alli also include advice to adhere to a low-fat diet and exercise plan to increase weight loss.
Side Effects
When the drug contained in Alli binds fat in the food you eat, it is passed into the stool. The most common side effect of Alli is greasy stools but may also include diarrhea and an urgent need to have bowel movements. Alli may also have negative effects on the liver. This is being investigated by the U.S. Food and Drug Administration. Do not take Alli if you have a liver condition. Alli may also interfere with the absorption of some fat-soluble vitamins, such as vitamins A, D and E. Talk to your doctor about your weight-loss plans for advice on your diet and exercise plan.
