Side Effects of Phentamine

Phentermine is the name of a prescription medication used for weight loss and management. It is intended to be a short-term option for people who want to lose weight. It functions by decreasing the appetite, while simultaneously speeding up the metabolism. It is similar, chemical wise, to amphetamines. As with any medicine, some possible negative side effects are occasionally associated with Phentermine use.

Common Side Effects

• Several common side effects could occur from taking Phentermine. In general, these side effects are considered to be minor and subside after the body has adapted to the medicine. However, if they persist or intensify, medical attention might be necessary. Some common side effects include sex drive changes, unpleasant taste in the mouth, diarrhea, constipation, restlessness, being overstimulated, headache, dry mouth, dizziness, feeling lightheaded, hard time sleeping, upset stomach and insomnia.

Serious Side Effects

• Some serious side effects could also occur from taking Phentermine. In cases of potentially harmful side effects, individuals should stop taking the medicine and seek immediate medical assistance. Some signs of serious Phentermine side effects include abnormal behaviors, shortness of breath, feet or legs swelling up, tremors, passing out, chest ache, chest pounding and rapid heartbeat.

Allergic Reactions

• Allergic reactions are sometimes signs of negative Phentermine side effects. If a person experiences allergic reactions due to the medication, he should immediately contact their physician. Some signs of allergic reaction include itchiness, breaking out into hives, skin rash, chest tightness, trouble breathing, and swelling of the lips, mouth, face and tongue.

Caution

• It is vital to exercise caution when it comes to taking Phentermine. If the medication is taken alongside other diet medicines (like dexfenfluramine), it could bring upon an uncommon and life-threatening lung condition known as pulmonary hypertension. The medication should not be taken alongside other diet drugs without the consultation of a physician. Also, because Phentermine can bring upon side effects that could alter a person's reactions or thoughts, people planning to drive or need to stay alert should be particularly cautious.

Other Conditions

• Some people should avoid taking Phentermine in general. They include those who are allergic to stimulants or Phentermine itself, as well as those who have overactive thyroid, hypertension, heart disease, glaucoma, arteriosclerosis, or those who have a past of alcohol or drug addiction. Some people must notify their physicians beforehand when considering Phentermine, such as those who have diabetes, anxiety-related disorders, thyroid conditions or epilepsy.
