Phentermine is a drug typically used to help patients fight health-destroying obesity. It can have a powerful weight loss effect when combined with other aspects of a healthy lifestyle (such as frequent exercise and a well-balanced diet).

As with most drugs on the market, there have been several phentermine clinical studies designed to determine both the safety and the potential side effects of the drug. Here are some of the results.

The Common Side Effects

Most of the side effects are common and readily noticeable. They include things like an elevated heart rate (you might notice your race is pulsing), palpitations (the feeling of your heart pounding in your chest), and high blood pressure.

You might experience a headache, restlessness, the inability to sleep or a feeling of euphoria (a pleasant, detached sensation). Some of the symptoms affect your stomach, things like constipation, bloating and a weird taste on your tongue.

Although unpleasant, most of these side effects can be coped with. Some of them, such as a headache, can be alleviated by common over the counter drugs like Tylenol or Advil. While a doctor should be aware of anything you are feeling, in the phentermine clinical studies the side effects did not signal a bigger problem.

Uncommon Side Effects

The uncommon side effects found in the phentermine clinical studies tend to be a little more serious. Some patients experienced things like seizures, severe hallucinations, fainting or the desire to hurt people. Depression, extreme stomach problems and heart trouble are other examples.

These side effects have the potential to cause more harm than good. Patients who experienced those effects sometimes have to stop taking the drug and find an alternate method of weight loss. Luckily, there are other options; however, most people do not have these problems with it.

Continuing Studies

Studies continue to be conducted to determine how to make phentermine a better drug, either alone or in combination with other drugs. As these studies go on, new side effects may be discovered or ways to counter existing effects may become known.

If you are taking the drug, it is possible to experience an effect not yet known; this is because everyone’s body is unique. If you are concerned about your reaction to a drug like phentermine, you should always speak with a qualified physician to determine whether or not to continue with the medication.
