Phendimetrazine is a prescription medication indicated in the short-term treatment of obesity. This medication is anorectic drug that acts by stimulating the central nervous system, which can lead to a decreased appetite and weight loss in treated patients. Discuss the side effects of phendimetrazine with a doctor before beginning treatment with this medication.
Mood or Behavioral Changes
Patients receiving treatment with phendimetrazine can experience mood or behavioral changes as side effects of this medication. Unusual sensations of restlessness, nervousness or anxiety can occur, which may cause involuntary muscle shaking or tremors in certain patients, warns Drugs.com, a peer-reviewed drug information website for consumers. Patients who experience confusion, hallucinations or other abnormal behavior while taking phendimetrazine should contact a doctor immediately.
Stomach Upset
Symptoms of stomach upset can arise in certain patients following treatment with phendimetrazine. Stomach upset side effects can include stomach pain or nausea, which may be accompanied by diarrhea or constipation. These side effects can lead to decreased appetite in certain patients.
Difficulty Sleeping
While receiving treatment with phendimetrazine, patients may develop sleeping difficulties. This medication stimulates the central nervous system, which can make it difficult for patients to fall asleep or stay asleep through the night, a condition called insomnia. Patients who do not get adequate amounts of sleep may experience increased fatigue during the day that can affect productivity at work or school.
Dry Mouth
Sensations of dry mouth can arise in certain patients taking phendimetrazine, explains Drugs.com. If this occurs, patients may experience throat discomfort or increased thirst as side effects of dry mouth. An unpleasant taste may develop in the mouth following treatment with this medication, which may contribute to stomach upset side effects.
Decreased Libido
Patients taking this medication may experience a decrease in sexual drive or desire as a side effect of treatment. Men may have difficulty becoming aroused during sexual stimulation--a condition called impotence. It may become difficult for women to achieve orgasm, which can contribute to a decreased interest in sex. If these side effects begin to interfere with intimate relationships, contact a doctor for further guidance and care.
Heart Rate or Blood Pressure Abnormalities
During treatment with phendimetrazine, patients may develop heart rate or blood pressure abnormalities as side effects of this medication, explains Daily Med, a medication information website supported by the National Institutes of Health. An irregular heartbeat or increased blood pressure can cause symptoms of severe headache or blurred vision. These side effects are serious and require immediate medical intervention to prevent further complications.
