There may be a slightly increased risk of serious, possibly fatal side effects (such as heart failure, fast/irregular heartbeat, pneumonia) when this medication is used by older adults with dementia.

Discuss the risks and benefits of this medication, as well as other effective and possibly safer treatments for dementia-related behavior problems, with the doctor.Who should not take trifluoperazine?
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.
Take this medication by mouth with or without food, usually once or twice daily or as directed by your doctor.
Dosage is based on your medical condition, age, and response to treatment. In children, the dosage is also based on weight. To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor's instructions carefully.
Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day.
Although you may notice some medication effects soon after starting, it may take 2 to 3 weeks before you get the full benefit of this drug.
Do not stop taking this medication without consulting your doctor. Some conditions may become worse when this drug is suddenly stopped. Also, you may experience symptoms such as upset stomach, nausea, vomiting, dizziness, and shakiness. To prevent these symptoms while you are stopping treatment with this drug, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details. Report any new or worsening symptoms right away.
Tell your doctor if your condition does not improve or if it worsens.
Drowsiness, dizziness, dry mouth, blurred vision, tiredness, constipation, weight gain, and trouble sleeping may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
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 right away 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.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if any of these unlikely but serious side effects occur: difficulty urinating, sunburn-like rash (sun sensitivity), decreased cough reflex, swelling of the feet/ankles, butterfly-shaped rash on nose and cheeks, joint pain, skin discoloration, eye/vision changes, feeling unusually cold or hot.
Infrequently, this medication may cause face/muscle twitching and uncontrollable movements (tardive dyskinesia). In some cases, this condition may be permanent. Tell your doctor right away if you develop any uncontrollable movements such as lip smacking, mouth puckering, tongue thrusting, chewing, or unusual arm/leg movements.
In rare cases, trifluoperazine may increase your level of a certain chemical made by the body (prolactin). For females, this increase in prolactin may result in unwanted breast milk, missed/stopped periods, or difficulty becoming pregnant. For males, it may result in decreased sexual ability, inability to produce sperm, or enlarged breasts. If you develop any of these symptoms, tell your doctor right away.
Rarely, males may have a painful or prolonged erection lasting 4 or more hours. If this occurs, stop using this drug and seek immediate medical attention, or permanent problems could occur.
Tell your doctor right away if any of these rare but serious side effects occur: signs of liver problems (such as yellowing eyes/skin, persistent nausea, vomiting, stomach/abdominal pain), signs of infection (such as fever, persistent sore throat), easy bruising/bleeding, signs of anemia (such as severe tiredness, fast breathing, pale skin, fast heartbeat), mental/mood changes (such as worsening psychosis, unresponsive/catatonic state).
Seek immediate medical attention if any of these rare but serious side effects occur: slowed breathing, chest pain, seizures.
This medication may rarely cause a very serious condition called neuroleptic malignant syndrome (NMS). Get medical help right away if you have any of the following symptoms: fever, muscle stiffness/pain/tenderness/weakness, severe tiredness, severe confusion, sweating, fast/irregular heartbeat, dark urine, change in the amount of urine.
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
