Bontril SR® is a brand name for a slow-release version of phendimetrazine, a stimulant drug prescribed as an appetite suppressant and weight reduction pill. Like many weight loss pills, the stimulant effects of Bontril SR® can reduce an individual's hunger and assist him or her in losing weight. The drug is generally prescribed only for short-term use, however, as its efficacy as an appetite suppressant eventually subsides after several weeks of use. Like all drugs, use of Bontril SR® carries with it certain risks and side effects that users should pay attention to in order to prevent possible serious health problems. The slow release version of the drug can help reduce unpleasant side effects and may also reduce a patient's risk of developing stimulant dependency.

For many people who desire to lose weight, diet pills can be a useful tool in modifying their eating habits and reaching weight loss goals. Doctors will sometimes prescribe diet pills such as Bontril SR® to be used in conjunction with a diet and exercise plan. While some weight-loss drugs may be prescribed for long-term use, others may only be prescribed for short period of time. This is often because the drugs themselves are only effective for a specific time period before the user's body becomes accustomed to the drug and it no longer has the desired effect.

Like many stimulant drugs, side effects of using Bontril SR® include possible restlessness, rapid heartbeat, and even blurred vision. Individuals who have cardiac conditions should not take this drug. As a general rule, people who take Bontril SR® will take it only once a day before a meal and will take it only early in the day to avoid problems with insomnia. Medical literature on the drug suggests that the risk of developing side effects from taking the drug can increase if it is taken for long periods of time.

Other concerns for people taking this drug include the risk that they may become dependent or addicted. This is a known risk of stimulant use and is not restricted to Bontril SR®. When it is time for patients to stop taking the drug, they should only do so while working with their physician to minimize and manage withdrawal symptoms. If someone suddenly stops taking the drug, he may experience severe fatigue and possibly even depression. Individuals using this or any other weight reduction pill should also discuss with their doctor their plans for maintaining or continuing any weight loss experienced while they were undergoing drug therapy.
