Thioridazine Oral

In Depth

Generic Name: THIORIDAZINE SUSPENSION - ORAL
Pronounced: (thigh-oh-RID-uh-zeen)

Thioridazine Oral Warning

Thioridazine rarely has caused very serious (possibly fatal) irregular heartbeat (QT prolongation in the EKG). Therefore, it should be used only in patients who have not shown improvement with at least 2 other antipsychotic medications or who cannot tolerate other antipsychotic medications. This medication should not be used with other medications that can also cause a slow or irregular heartbeat. (See also Drug Interactions.)

Thioridazine Oral Side Effects

Dizziness, drowsiness, difficulty urinating, restlessness, headache, and blurred vision may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

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 if any of these serious side effects occur:

  • shakiness (tremors)
  • muscle stiffness
  • mask-like facial expression
  • jerking movements while walking


Thioridazine may rarely cause a condition known as tardive dyskinesia. In some cases this condition may be permanent. Tell your doctor immediately if you develop any unusual/uncontrolled movements (especially of the face, lips, tongue, arms or legs).

In rare cases, thioridazine 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 immediately.

Tell your doctor immediately if any of these rare but very serious side effects occur:

  • signs of infection (e.g., fever, persistent sore throat)
  • vision changes (e.g., vision loss, sudden difficulty seeing at night, brown-tinged vision)


Seek immediate medical attention if any of these rare but very serious side effects occur:
