Description

Used in the treatment of hyperkinetic movement disorders such as Huntington's chorea, Hemiballismus, Senile Chorea, Tic and Gille's de la Tourette Syndrome and Tardive Dyskinesia.

Directions

General: The initial dose should be low, and dosage should be titrated slowly according to the tolerance and responsiveness of the individual patient.
Adults: An initial starting dose of 12.5 mg 2 to 3 times a day is recommended. This can be increased by 12.5 mg a day every 3 to 5 days until the maximal tolerated and effective dose is reached for the individual, and may have to be up/down titrated depending on individual tolerance. In most cases the maximal tolerated dose will be 25 mg t.i.d. In very rare cases, a 200 mg dose has been reached (the maximum recommended dose in some publications).
If there is no improvement at the maximal tolerated dose in 7 days, it is unlikely that tetrabenazine will be of benefit to the patient, either by increasing the dose or by extending the duration of treatment.
Geriatrics and Debilitated Patients: No adequately controlled clinical studies have been performed in the elderly and/or debilitated patients. Clinical experience suggests that a reduced initial and maintenance dose should be used. Parkinsonian-like adverse reactions are relatively common in these patients and may be dose-limiting.
Children: No adequately controlled clinical studies have been performed in children. Limited clinical experience suggests that treatment should be started at approximately half the adult dose, and titrated slowly and carefully according to tolerance and individual response.

Cautions

General: Occupational Hazards: Tetrabenazine may cause drowsiness and orthostatic hypotension. Therefore caution is recommended when driving, operating machinery, or performing other skilled tasks until the effect of tetrabenazine is known.
Pregnancy: Animal reproductive studies have not been performed with tetrabenazine. There is no information on the safety of the drug in human pregnancy. However, tetrabenazine has been used for many years and no cases of malformation have been reported.
Lactation: Limited information indicates that tetrabenazine is excreted in milk, therefore it should be avoided in breast-feeding mothers.
