Trilafon (perphenazine) is from a group of drugs called phenothiazines. It is a conventional or typical antipsychotic medication that is only available via a doctor or psychiatrist’s prescription.
What Is Trilafon Used to Treat?
This psychotropic medication is used to treat some of the symptoms of schizophrenia, including hallucinations, delusions, loss of interest in life, and erratic behavior. It works by reducing excessive levels of excitement in the brain. This medication will not cure schizophrenia, but it will help control the extreme thoughts and behaviors that often accompany the condition. In some cases, this medication may also be used to treat extreme cases of nausea or vomiting.
- How do I get the most out of my treatment with this drug?
Psychotropic medication can help many people achieve a higher quality of life and/or undergo effective treatment for mental health conditions in the face of debilitating symptoms. Medication alone, however, fails to address many of the emotions, thoughts, behaviors, and environmental factors that contribute to mental health issues. Finding a qualified therapist or counselor to complement your treatment if you are prescribed an antipsychotic drug can help you better understand your mental health diagnosis as well as provide you with coping strategies such as breathing exercises, meditation, or cognitive restructuring to ensure better, longer-lasting results with your mental health treatment.
- How should I take this medication?
Trilafon comes in oral tablet form and is usually taken two to four times per day. This medication should be taken consistently for best results. Your doctor may recommend that you start out on an average dose, and then increase or decrease the dose over time in order to find what is ideal for you.
- What should I do if I forget to take a dose?
If you miss a dose, take the missed dose as soon as you remember it. However, if you are close to the time for your next scheduled dose, then skip the missed dose completely. You may increase the risk of an overdose if you take too much of this drug too quickly.
- What should I do if I overdose on this medication?
Call your doctor or a poison helpline immediately. An overdose of Trilafon may be deadly. Common symptoms of overdose include fast or erratic heartbeat, convulsions, difficulty responding to surroundings, and loss of consciousness.
