Pregnancy Category

Name : Not Classified
Description
FDA has not yet classified the drug into a specified pregnancy category.

Mode of Action

Reversibly inhibits human vesicular monoamine transporter type 2 (VMAT2), resulting in decreased uptake of monoamines (eg, dopamine, serotonin, norepinephrine, histamine) into synaptic vesicles and depletion of monoamine stores from nerve terminals This effect is similar to reserpine, but with less peripheral activity and is shorter-acting

Interaction

Tetrabenazine should not be given with or within 14 days of discontinuation of MAOI therapy. Blocks action of reserpine. Decreases effects of levodopa and worsen parkinsonism. Increased risk of extrapyramidal side effects when given with amantadine, metoclopramide, antipsychotics.
