After taking your medicine
What unwanted effects might ‘Trifluoperazine’ have?
Blood clots in the veins especially in the legs (symptoms include swelling, pain and redness in the
leg), which may travel through blood vessels to the lungs causing chest pain and difficulty in
breathing. If you notice any of these symptoms seek medical advice immediately.
Any medicine can cause unwanted effects. Some patients may experience weakness, drowsiness,
dizziness, restlessness, difficulty in sleeping, dry mouth, blurred vision, and muscle weakness, loss of
appetite, faintness on standing up, skin rashes (including increased sensitivity to the sun), weight
gain, water retention or confusion.
Very rarely patients may experience a fast or irregular heartbeat, constipation, difficulty in passing
urine or a high temperature. Rarely ‘Trifluoperazine’ may affect certain types of breast cancers, or
lead to breast enlargement in men or to inappropriate milk production or altered menstrual cycle (e.g.
periods stop). Occasionally some patients have complained of feeling dulled, whilst others of being
Very occasionally, medicines such as ‘Trifluoperazine’ can have effects on muscle control. If this
happens symptoms can include slurred speech, odd movements of the face, particularly of the
tongue, eyes, head or neck (such as twisting of the neck which causes an unnatural postitioning of the
head), rigid muscles, tremors or restlessness and difficulty in sitting still. Some patients (especially
those on high doses of ‘Trifluoperazine’) experience problems with muscle control, which may
continue for years. Such patients may experience constant chewing or tongue movements or other

gentle movements of the head, neck or trunk. Uncontrollable movements of the arms and legs have
also been reported in these patients.
If these effects occur tell your doctor straight away.
Rarely patients taking ‘Trifluoperazine’ develop an unusual reaction, even though they may have
been taking it for some time. Symptoms of this reaction are a high temperature, rigid muscles,
drowsiness and occasional loss of consciousness. This is called Neuroleptic Malignant Syndrome and
requires emergency admission to hospital for treatment.
In elderly people with dementia, a small increase in the number of deaths has been reported for
patients taking antipsychotics compared with those not receiving antipsychotics.
If you have angina and your pain becomes worse, tell your doctor straight away.
There have been very rare reports of jaundice (yellowing of the skin and eyes), eye problems, skin
colouring (pigmentation), and blood problems. If you get a bad sore throat or high fever or become
very tired and pale or you notice bruises and nose bleeds tell your doctor.
Nausea, vomiting, insomnia and involuntary muscle disorders are all possible if
treatment is suddenly stopped.
Your doctor should check your progress regularly, if you are on ‘Trifluoperazine’ for a
long time, to make sure no unwanted effects are developing.
Tell your doctor or pharmacist (chemist) if you notice any of the above, unwanted
