What happens if I overdose?

Seek emergency medical attention.

Symptoms of a trifluoperazine overdose include uncontrollable movements, agitation, seizures, severe dizziness or fainting, coma, very deep sleep, irregular heartbeats, and high or low body temperature.

What should I avoid while taking trifluoperazine?

Use caution when driving, operating machinery, or performing other hazardous activities. Trifluoperazine may cause dizziness or drowsiness. If you experience dizziness or drowsiness, avoid these activities.

Dizziness may be more likely to occur when you rise from a sitting or lying position. Rise slowly to prevent dizziness and a possible fall.

Use alcohol cautiously. Alcohol may increase drowsiness and dizziness while taking trifluoperazine. Avoid prolonged exposure to sunlight. Trifluoperazine may increase the sensitivity of the skin to sunlight. Use a sunscreen and wear protective clothing when sun exposure is unavoidable.

What are the possible side effects of trifluoperazine?

If you experience any of the following serious side effects, stop taking trifluoperazine and seek emergency medical treatment:

• an allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, tongue, or face; or hives);

• uncontrollable movements of the tongue, face, lips, arms, or legs;

• muscle spasms of the face or neck;

• severe restlessness or tremor;

• severe drowsiness or fainting; or

• a rash.

Other, less serious side effects may be more likely to occur. Continue to take trifluoperazine and talk to your doctor if you experience

• decreased sweating;

• dry mouth or a stuffy nose;

• constipation;

• blurred vision;

• mild restlessness, drowsiness, or tremor;

• difficult urination, dark urine;

• decreased sex drive;

• dizziness;

• increased appetite; or

• menstrual irregularities or swollen breasts.

Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.

What other drugs will affect trifluoperazine?

Trifluoperazine may interact with other drugs that cause drowsiness, including alcohol, antidepressants, antihistamines, pain relievers, anxiety medicines, seizure medicines, and muscle relaxants. Dangerous sedation, dizziness, or drowsiness may occur if trifluoperazine is taken with alcohol or any of these medications. Talk to your doctor before taking trifluoperazine in combination with alcohol or any other prescription or over-the-counter medicines.

Trifluoperazine also interacts with medications other than the ones listed here. Before taking trifluoperazine, tell your doctor about all other prescription and over-the-counter medicines you are taking, including herbal products. During treatment, do not start taking any new drug without first talking to your doctor.
