Combining a well-balanced diet with regular physical activity is the healthiest and most effective way to lose weight. However, you may benefit from using a prescribed weight-loss medicine if you have a weight-related health problem and you struggle to lose weight through lifestyle alone. Although weight-loss medicines may seem like a simple means to an end, they are neither foolproof nor intended to replace healthy habits.
Consider the Risks
Prescription weight loss pills can decrease your risk of dying prematurely from weight-related health problems, but the pills also come with their share of potential dangers. Common side effects of a weight-loss medication depend on its active ingredients. Medications that block fat absorption may result in side effects such as passing gas, intestinal discomfort and leakage of oily stool. Medications that increase calorie burn may cause side effects such as higher heart rate, elevated blood pressure, anxiety and sleeplessness. Additionally, you may be at risk of pill dependence or abuse if you have a history of drug or alcohol abuse, according to the Weight-control Information Network. You may also develop a tolerance to weight-loss pills as time wears on, meaning the beneficial effects are likely to taper off after about six months of being on the medication.
Use Your Own Prescription
Your doctor should be the one to determine whether you are candidate for a weight loss prescription. Prescription weight-loss medications are only approved for people who are diagnosed as obese or extremely overweight with an obesity-related health problem such as Type 2 diabetes or high blood pressure. Additionally, patients must have previously attempted to lose weight through traditional means such as exercise and diet. Even if you qualify for medication, a friend or relative's prescription weight loss medication may not be safe or effective for you. Your doctor will help you weigh your options based on your medical history and current medications and medical conditions.
Calculate the Cost
Many insurance companies won't pay for you to take prescription weight-loss drugs, but some recognize obesity as a chronic disease and are increasingly covering the cost, according to the Weight-control Information Network. Ask your insurance company about potential coverage before you try to foot the bill yourself. If your insurance does cover prescription weight-loss medication, it may require you to obtain prior authorization before it covers the expense of the prescription. If your insurance company does not cover the cost, you may have to set aside $60 to more than $120 for each month's supply, as of 2011. Save accordingly.
Follow Up on Safety Studies
The weight-loss prescription drug sibutramine, also called Meridia, was approved in 1997 to help patients lose weight, but follow-up studies showed that it was associated with serious heart problems such as stroke and heart attack, according to MayoClinic.com. As a result, it was withdrawn from the U.S. market. As of 2011, the U.S. Food and Drug Administration is reviewing the weight loss pill orlistat, also called Xenical and Alli, due to reports of serious liver injury in patients taking the drug. Do your homework to ensure that you're informed about the medication you take.
Maintain Healthy Habits After Medication
Prescription weight-loss pills can help you lose some extra pounds in the beginning, which can get you off to a healthy running start in your weight loss endeavor. However, you are responsible for maintaining weight loss once you stop taking the medication. You will need to exercise most days of the week and eat a well-balanced diet that is low in calories if you want to maintain a healthy weight.
