Generic Name(S): Trifluoperazine



Stelazine (trifluoperazine) belongs to a class of drugs called conventional or typical antipsychotics. It is a prescription medication used primarily in the management of symptoms associated with schizophrenia. Stelazine may also be used as a short-term treatment for people who experience anxiety that have not responded to other medications. While this drug has proven to be effective in the management of certain symptoms, it will not cure schizophrenia or anxiety issues. Typically people experiencing those conditions seek additional treatment options such as psychotherapy in conjunction with taking medication.

Stelazine has been discontinued by its manufacturer and is no longer for sale in the United States as of 2004. It is available by its generic name only.

Dosage FAQs

  • What is the safest way to take this medication?
    Stelazine is available as tablets, multi-dose vials, and liquid concentrate (for institutional use).  When in tablet form, this drug is usually taken once or twice daily. For best results, try to take this medication at the same time each day. Do not take more or less of this medication, and do not take this medication for a longer or shorter period of time than is directed by your doctor.
  • What should I do if I forget to take a dose?
    Take the dose you forgot as soon as you remember it. However, if you are close to the time for your next scheduled dose, do not take the missed dose. You may put yourself at risk for an overdose if you take too much of this medication too quickly.
  • How do I know if I have overdosed on this medication?
    Check for common signs of overdose. These include drowsiness, erratic and uncontrollable body movements, fever, convulsions, agitation, constipation, changes in heart rate, restlessness, dry mouth, and coma.
  • What should I do if I have overdosed on this medication?
    Get urgent medical assistance or call a poison control center immediately. Do not attempt to throw up unless instructed to do so by poison control personnel.
  • What can I do to get the most out of my treatment with this drug?
    Pairing psychotropic drug treatment with a type of psychotherapy may help a person achieve better, longer-lasting mental health outcomes. While drugs help treat debilitating symptoms, they do not address behaviors, emotions, or teach healthy ways to cope when symptoms are triggered. Finding a qualified therapist or counselor can help you understand what you are experiencing in a safe environment, which can go a long way toward improving your quality of life. Additionally, many people report relief from associated symptoms such as depression or anxiety by engaging in meditation, yoga, or breathing exercises. These activities can be led by an instructor or self-guided and may help improve or remove some associated symptoms altogether.
  • How can I safely store this medication?
    Keep this drug tightly closed in its original packaging. Do not expose this medication to excessive amounts of heat or moisture. Avoid storing this medication in the bathroom or kitchen and keep it out of the reach of children.
