Brand Name: Stelazine

Stelazine is the brand name for Trifluoperazine, a high potency anti-psychotic medication in a class of drugs called phenothiazines. Anti-psychotic medications are also known as neuroleptics or major tranquilizers. Stelazine is classified as an antianxiety, antiemetic, and antipsychotic drug. This drug blocks receptors for the chemical dopamine in the brain. It also decreases the release of hormones from the hypothalamus and the pituitary gland.

How much of this drug is typically used?
Tablet: 1 mg, 2 mg, 5 mg, 10 mg

Children under 12 years old should only take Stelazine under the care of a child psychiatrist.

Stelazine may be given to children as young as 6 years old, but should be done only with extreme caution and careful supervision. In children 6 to 12 years old, starting dose is usually about 1 mg per day. Dosage in children under 12 rarely exceeds 15 mg per day. Stelazine is not habit forming, but if it is taken for a long time it may lead to a serious condition called tardive dyskinesia.

Suddenly discontinuing Stelazine may cause severe withdrawal symptoms such as nausea and vomiting, dizziness, or tremors. Dosage should be gradually tapered over a period of 2 to 3 weeks to minimize withdrawal.

When Stelazine is taken long-term, a riboflavin (vitamin B2) supplement should be taken.

Stelazine may impair coordination or mental alertness. Patients should not drive or operate heavy machinery until they know that Stelazine does not affect their ability to safely engage in such activities.

Stelazine can make it difficult to diagnose certain other medical conditions such as intestinal obstruction, brain tumor, and Reye's syndrome.
