What special precautions should I follow?[edit | edit source]

  • Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Trifluoperazine hydrochloride is not approved for the treatment of patients with dementia-related psychosis.
  • Tardive dyskinesia, a syndrome consisting of potentially irreversible, involuntary, dyskinetic movements, may develop in patients treated with antipsychotic drugs. If signs and symptoms of tardive dyskinesia appear in a patient on antipsychotics, drug discontinuation should be considered. However, some patients may require treatment despite the presence of the syndrome.
  • A potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) has been reported in association with antipsychotic drugs.
  • The management of NMS should include 1) immediate discontinuation of antipsychotic drugs and other drugs not essential to concurrent therapy, 2) intensive symptomatic treatment and medical monitoring, and 3) treatment of any concomitant serious medical problems for which specific treatments are available. There is no general agreement about specific pharmacological treatment regimens for uncomplicated NMS.
  • There is evidence that phenothiazines are excreted in the breast milk of nursing mothers. Because of the potential for serious adverse reactions in nursing infants from trifluoperazine, a decision should be made whether to discontinue nursing or to discontinue the drug.
  • Thrombocytopenia and anemia have been reported in patients receiving the drug. Agranulocytosis and pancytopenia have also been reported. If white blood cell and differential counts indicate cellular depression, stop treatment and start antibiotic and other suitable therapy.
  • Jaundice of the cholestatic type of hepatitis or liver damage has been reported.
  • Hypotension has occurred, large doses and parenteral administration should be avoided in patients with impaired cardiovascular systems. If hypotension occurs from parenteral or oral dosing, place patient in head-low position with legs raised. If a vasoconstrictor is required, norepinephrine bitartrate and phenylephrine hydrochloride are suitable.
  • Since certain phenothiazines have been reported to produce retinopathy, the drug should be discontinued if ophthalmoscopic examination or visual field studies should demonstrate retinal changes.
  • An antiemetic action of trifluoperazine hydrochloride may mask the signs and symptoms of toxicity or overdosage of other drugs and may obscure the diagnosis and treatment of other conditions such as intestinal obstruction, brain tumor and Reye’s syndrome.
  • Antipsychotic drugs elevate prolactin levels; the elevation persists during chronic administration.
  • Trifluoperazine may make your skin sensitive to sunlight. plan to avoid unnecessary or prolonged exposure to sunlight and to wear protective clothing, sunglasses, and sunscreen.
  • You should know that trifluoperazine may make it harder for your body to cool down when it gets very hot. Tell your doctor if you plan to do vigorous exercise or be exposed to extreme heat.
  • As with all drugs which exert an anticholinergic effect, and/or cause mydriasis, trifluoperazine should be used with caution in patients with glaucoma.
  • Trifluoperazine may cause dizziness, lightheadedness, and fainting when you get up too quickly from a lying position. To avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up.
  • If you are having a myelogram (x-ray examination of the spine), tell your doctor and the radiographer that you are taking trifluoperazine. Your doctor will probably tell you not to take trifluoperazine for 2 days before the myelogram and for one day after the myelogram.
  • Trifluoperazine may make you drowsy and may affect your thinking and movements, especially at the beginning of your treatment. Do not drive a car or operate machinery until you know how this medication affects you.
