Trifluoperazine

Name: Trifluoperazine

What is trifluoperazine, and how does it work (mechanism of action)?

Trifluoperazine is an oral antipsychotic medication used for the management of schizophrenia. Trifluoperazine is one of the older, first-generation antipsychotic medications. Examples of other first-generation antipsychotics include:

  • prochlorperazine (Compazine, Compro, Procomp)
  • chlorpromazine (Promapar, Thorazine)
  • perphenazine (Trilafon)
  • thioridazine (Mellaril)

Although the exact mechanism of antipsychotics is unknown, scientists believe that they may work by blocking the action of dopamine in the brain. Dopamine is a neurotransmitter (chemical) that nerves use to communicate with one another. Trifluoperazine is used when patients do not respond to other antipsychotics.

Which drugs or supplements interact with trifluoperazine?

Combining trifluoperazine with medications such as procainamide (Pronestyl), sotalol (Betapace), amiodarone (Cordarone), and dofetilide (Tikosyn) that affect heart rate and rhythm can cause abnormal heart beats.

Antidepressants such as fluoxetine (Prozac), sertraline (Zoloft), and and tricyclic antidepressants may reduce the break down of trifluoperazine, leading to increased blood levels and more side effects of trifluoperazine.

Trifluoperazine should be used with caution with medications that depress the central nervous system and cause sedation or drowsiness. Examples include alprazolam (Xanax), lonazepam (Klonopin), zolpidem (Ambien), codeine, morphine, and alcohol. Such combinations can cause excessive sedation, drowsiness, weakness, confusion, speech impairment, and in severe cases coma or death. Combining alcohol with trifluoperazine also increases the risk of low blood pressure.

Is trifluoperazine safe to take if I'm pregnant or breastfeeding?

Use of trifluoperazine during pregnancy has not been adequately studied. Neonates exposed to antipsychotics during the third trimester of pregnancy are at risk for extrapyramidal and withdrawal symptoms after birth. Symptoms reported included agitation, hypertonia, hypotonia, tremor, somnolence, depressed breathing, and feeding disorder.

Safe use of trifluoperazine by nursing mothers has not been established.

N.B.: The Concentrate is for use in schizophrenia when oral medication is preferred and other oral forms are considered impractical.

Indications

For the management of schizophrenia.

Stelazine (trifluoperazine HCl) is effective for the short-term treatment of generalized non-psychotic anxiety. However, Stelazine (trifluoperazine) is not the first drug to be used in therapy for most patients with non-psychotic anxiety because certain risks associated with its use are not shared by common alternative treatments (i.e., benzodiazepines).

When used in the treatment of non-psychotic anxiety, Stelazine (trifluoperazine) should not be administered at doses of more than 6 mg per day or for longer than 12 weeks because the use of Stelazine (trifluoperazine) at higher doses or for longer intervals may cause persistent tardive dyskinesia that may prove irreversible (see WARNINGS).

The effectiveness of Stelazine (trifluoperazine) as a treatment for non-psychotic anxiety was established in a 4-week clinical multicenter study of outpatients with generalized anxiety disorder (DSM-III). This evidence does not predict that Stelazine (trifluoperazine) will be useful in patients with other non-psychotic conditions in which anxiety, or signs that mimic anxiety, are found (i.e., physical illness, organic mental conditions, agitated depression, character pathologies, etc.).

Stelazine (trifluoperazine HC1) has not been shown effective in the management of behavioral complications in patients with mental retardation.

Trifluoperazine Overview

Trifluoperazine is a prescription medication used to treat schizophrenia or anxiety. Trifluoperazine belongs to a group of drugs called typical antipsychotics, which work by altering the level of certain natural substances in the brain to restore mental balance.

This medication comes in tablet form and is typically taken 2 times a day, with or without food.

Common side effects of trifluoperazine include drowsiness, dizziness, skin reactions, rash, and dry mouth. Do not drive or operate heavy machinery until you know how trifluoperazine affects you.

What is the most important information I should know about trifluoperazine?

Trifluoperazine is not approved for use in psychotic conditions related to dementia. Trifluoperazine may increase the risk of death in older adults with dementia-related conditions.

You should not use trifluoperazine if you have bone marrow suppression, liver disease, a blood cell disorder, or if you have drowsiness, slow breathing, weak pulse, or decreased alertness (such as after drinking alcohol or taking medicines that make you sleepy).

How should I take trifluoperazine?

Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Call your doctor if your symptoms do not improve, or if they get worse while using trifluoperazine.

Do not stop using trifluoperazine suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using trifluoperazine.

Store at room temperature away from moisture, heat, and light.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Overdose symptoms may include dry mouth, constipation, extreme drowsiness or feeling restless and agitated, changes in heart rate, fainting, and seizure (convulsions).

How is this medicine (Trifluoperazine) best taken?

Use trifluoperazine as ordered by your doctor. Read all information given to you. Follow all instructions closely.

  • Drink lots of noncaffeine liquids unless told to drink less liquid by your doctor.
  • Keep taking this medicine as you have been told by your doctor or other health care provider, even if you feel well.

What do I do if I miss a dose?

  • Take a missed dose as soon as you think about it.
  • If it is close to the time for your next dose, skip the missed dose and go back to your normal time.
  • Do not take 2 doses at the same time or extra doses.

How do I store and/or throw out Trifluoperazine?

  • Store at room temperature.
  • Store in a dry place. Do not store in a bathroom.
  • Protect from light.
  • Keep all drugs in a safe place. Keep all drugs out of the reach of children and pets.
  • Check with your pharmacist about how to throw out unused drugs.

ALERT U.S. Boxed Warning

Increased mortality in elderly patients with dementia-related psychosis:

Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analyses of 17 placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients between 1.6 and 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was approximately 4.5%, compared to a rate of approximately 2.6% in the placebo group. Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (eg, heart failure, sudden death) or infectious (eg, pneumonia) in nature. Observational studies suggest that, similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality. The extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear. Trifluoperazine is not approved for the treatment of patients with dementia-related psychosis.
