Tetrabenazine

Tetrabenazine is a medication primarily used to treat movement disorders such as Huntington's disease, tardive dyskinesia, and chorea. It works by regulating the levels of certain neurotransmitters in the brain, helping control involuntary movements. Tetrabenazine is a dopamine depleting agent that reduces the excess activity in the brain that leads to uncontrolled movements. This medication plays a crucial role in improving the quality of life for people suffering from these conditions.

Uses of Tetrabenazine

• Treats chorea associated with Huntington's disease.
• Helps manage tardive dyskinesia, a condition causing involuntary movements.
• Reduces abnormal movements caused by other neurological conditions.
• Can be used for other movement disorders as prescribed by a doctor.

How Tetrabenazine Works

Tetrabenazine works by depleting the levels of dopamine in the brain. It binds to the vesicular monoamine transporter (VMAT2), which is responsible for transporting dopamine into nerve endings. By limiting dopamine release, Tetrabenazine reduces the abnormal movements seen in conditions like Huntington's disease and tardive dyskinesia, helping restore more controlled and purposeful movement.

Benefits of Tetrabenazine

• Reduces involuntary movements (chorea) in patients with Huntington's disease.
• Helps control tardive dyskinesia, reducing repetitive, involuntary movements caused by antipsychotic medications.
• Improves motor function and quality of life for individuals with movement disorders.
• Provides relief from symptoms of excessive and unwanted movement, allowing for greater independence in daily activities.

How to Take Tetrabenazine

Tetrabenazine is typically taken orally in the form of tablets. The dosage will depend on the condition being treated and will be prescribed by your healthcare provider. It is important to follow your doctor’s instructions regarding dosage and frequency. Tetrabenazine should be taken with food to minimize gastrointestinal side effects. It is essential to take the full prescribed course, even if symptoms improve, to achieve the best results.

Safety Advice

• Tell your doctor if you have a history of depression, suicidal thoughts, or cardiovascular problems.
• Avoid driving or operating heavy machinery if you experience drowsiness or fatigue after taking Tetrabenazine.
• Consult your doctor before using Tetrabenazine if you are pregnant or breastfeeding.
