There are a number of drugs for weight loss. However, many of them have given rise to controversies due to their various side effects. Phentermine is one of the drugs known to cause side effects in certain people under certain circumstances. However, the side effects caused by Phentermine are mostly temporary. As long as people follow the prescription properly, they would mostly not face severe complications.

The following are some of the guidelines that people can use to lose weight safely and effectively while on Phentermine.

1. The drug should always be purchased from an authorized source. Buying them from unauthorized sources can be quite dangerous. People should always consult their doctor when they have any suspicion about the authenticity of any drug that they have purchased.

2. People who are already on other weight loss medications should consult with their physician when they decide to use Phentermine.

3. When patients who are using the drug need to undergo surgery or other major treatments for any other reason, they should immediately inform the surgeon that they are currently using Phentermine.

4. People should never take a double dose of the drug to compensate for a missed dose. This could lead to a lot of complications. This should never be done for any other drug as well. Only the prescribed dosage should be followed at the correct intervals. Missing a dose or taking it late at night can often make the drug ineffective.

5. Patients who are on extensive medication for a prolonged illness should not use Phentermine. The drug should never be taken by patients who suffer from any kind of active thyroid problems, hypertension, diabetes or glaucoma. Pregnant women and breast feeding mothers should also avoid this drug. When complications arise from such usage, patients should seek medical attention as soon as possible.

6. People using Phentermine should avoid smoking and alcohol. They should also avoid caffeine and decongestants as they can increase the heart rate of the patient and put them in danger. Antidepressants should also be avoided as they reduce the effectiveness of the drug.

7. Phentermine works well when patients follow a good exercise regimen and a proper diet plan. Side effects like nervousness, high blood pressure, irritability, constipation, and loose motion are sometimes felt by obese people. A family physician who knows their medical history would be able to prescribe the appropriate medication for their specific condition.

Phentermine will be more effective in helping people lose weight when they follow these general guidelines. It will also make the drug safe to use and avoid most of the side effects.
