trifluoperazine oral Uses
This medication is used to treat certain mental/mood disorders (such as schizophrenia, psychotic disorders). Trifluoperazine helps you to think more clearly, feel less nervous, and take part in everyday life. It can reduce aggressive behavior and the desire to hurt yourself/others. It may also help to decrease hallucinations (hearing/seeing things that are not there). Trifluoperazine is a psychiatric medication that belongs to the class of drugs called phenothiazine antipsychotics. It works by helping to restore the balance of certain natural substances in the brain.
This medication has also been used for the short-term treatment of anxiety. However, there are safer drugs to treat anxiety that should be used first before trifluoperazine.How to use trifluoperazine oral

Also, you may experience symptoms such as upset stomach, nausea, vomiting, dizziness, and shakiness.

To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
This drug may cause muscle/nervous system problems (extrapyramidal symptoms-EPS). Your doctor may prescribe another medication to decrease these side effects. Tell your doctor immediately if you notice any of the following side effects: feelings of anxiety/agitation/jitteriness, drooling/trouble swallowing, restlessness/constant need to move, shaking (tremor), shuffling walk, stiff muscles, severe muscle spasms/cramping (such as twisting neck, arching back, eyes rolling up), mask-like expression of the face.
