What are the Side Effects of Phentermine?

Phentermine is a weight loss pill that is used as a short term treatment medication for obese patients. Phentermine is used in conjunction with diet and a regular exercise program. Physicians do not prescribe Phentermine for a long term treatment medication because of the side effects that it can bring due to prolonged use.

Since Phentermine is an amine and is chemically related to amphetamine, it can also produce amphetamine-like side effects. However, side effects are subtle that most people drinking the drug can tolerate it. The possibility of more serious side effects usually occur once the dosage of Phentermine is too high.

Before a drug is released to the market, series of studies are conducted first. The release of a certain drug may take as long as ten years just to prove its effectiveness and safety. When Phentermine was still under study, experts have found out that Phentermine causes some side effects that people who will be taking it should know.

Here are some of the minor side effects that Phentermine can bring:

Insomnia or difficulty to sleep at night.
Change in mood such as sudden elevation or euphoria, and sudden depression or dysphoria.
Gastrointestinal related symptoms such as constipation and diarrhea
Hyperactivity due to the drug’s sympathomimetic properties.
Restlessness or easy fatigability resulting from hyperactivity.
Dizziness

However, given these minor side effects; Phentermine takers should also know that there are life-threatening adverse reactions that can occur from taking the drug. Pulmonary hypertension is an adverse effect that a Phentermine taker should be aware of. Here are some of the manifestations of pulmonary hypertension that a Phentermine taker should observe:

Difficulty of breathing and pain in the chest.
Dizziness that could lead to fainting spells.
Cyanosis or bluish discoloration of the skin and the lips.
Swelling of the ankle.

Once you have observed that you have one of these symptoms, you should immediately seek medical attention. Phentermine cannot be abruptly ceased because it can cause a rebound effect. Physicians would often lower or taper the dosage before completely stopping the drug. This is also to avoid manifestations of withdrawal symptoms associated with the drug.

Unfortunately Phentermine is no longer available online without a doctors prescription due to FDA regulations. Phentramin-D however has been released to the public in replacement of Phentermine. Phentramin-D is a phamceutical-grade diet pill that delivers the same results as Phentermine without the adverse side effects.
