Phendimetrazine is a prescription medication used as a short-term method to help overweight or obese patients lose weight. This medication is intended to be used in conjunction with healthy diet and exercise plans. Phendimetrazine aids in weight loss by reducing a patient's normal appetite, which may help reduce the number of calories a patient consumes each day. Patients should discuss the side effects of phendimetrazine diet pills with a medical professional before beginning treatment.
Restlessness, Nervousness or Anxiety
While taking phendimetrazine, patients may experience unusual sensations of restlessness, nervousness or anxiety. These emotional changes may manifest as physical tremors or shaking, Drugs.com warns. Though these side effects may diminish with continued use of this diet pill, patients who experience severe or persistent restlessness or anxiety should seek care from a doctor.
Insomnia
This medication stimulates the central nervous system, which can lead to sleeping difficulties in certain patients. Patients may find it difficult to fall asleep or stay asleep through the night, a side effect called insomnia, RxList reports. Frequent or recurrent episodes of insomnia may cause increased daytime fatigue. Patients who experience daytime fatigue may have difficulty remaining alert, attentive or focused during normal daily activities.
Bowel Movement Changes
After taking a dose of phendimetrazine, patients may experience bowel movement changes as a side effect of treatment, Drugs.com explains. Affected patients may have difficult or painful bowel movements, called constipation, or frequent, watery bowel movements, called diarrhea. These bowel movement changes may also cause additional stomach-related side effects, including nausea or stomach pain.
Blurred Vision, Dizziness or Headache
Treatment with this diet pill may cause blurred vision or dizziness in certain patients. Episodes of dizziness may occur in conjunction with headache and can lead to instability while standing or walking. Patients who experience dizziness should remain seated until this sensation passes in order to limit their risk of sustaining an injury from tripping or falling down.
Unpleasant Taste or Dry Mouth
Phendimetrazine is administered orally as a tablet up to three times daily or as prescribed by a doctor, Drugs.com explains. After patients place this medication in their mouth, they may develop a temporary but unpleasant or bitter taste in the mouth. Certain patients may also develop dry mouth side effects, which can cause increased thirst, throat irritation or thickened saliva.
Libido or Sexual Changes

Obese or overweight men who take this medication may develop impotence, a side effect characterized by difficulty maintaining or achieving an erection, Drugs.com reports. Both men and women taking this type of diet pill may also experience a decrease in their normal sexual libido. If these side effects are bothersome, affected patients should contact a physician for further guidance and care.
