Revocon 12.5 MG is a medication primarily used to treat chorea associated with Huntington's disease. The active ingredient in this medication is Tetrabenazine, which works by inhibiting the vesicular monoamine transporter 2 (VMAT-2). This action reduces the levels of certain neurotransmitters, including dopamine, serotonin, and norepinephrine, which helps reduce involuntary movements or jerky motions associated with Huntington's disease. It is typically prescribed for patients with Huntington's disease who experience chorea (abnormal involuntary movements), and the dosage is gradually adjusted to suit the individual’s needs. Common side effects may include sedation, depression, anxiety, and fatigue. It’s important to follow the doctor’s instructions carefully when taking this medication.
