Valbenazine (Ingrezza) is a medicine used to treat adults with tardive dyskinesia (TD) who have Tourette syndrome. It works by blocking the action of a certain type of neurotransmitter (dopamine) in the brain, which helps reduce the involuntary movements associated with TD. Valbenazine can be taken as a pill once a day, and its effects may be felt within 4-6 weeks of starting treatment.
Valbenazine is a medication used to treat tardive dyskinesia (TD). Here's a closer look at its key features:
Condition it treats:
- Tardive Dyskinesia (TD): This is a movement disorder that can develop as a side effect of taking antipsychotic medications for an extended period. TD causes involuntary, repetitive movements of the face, tongue, or limbs.
How it works: The exact mechanism of action for valbenazine in treating TD is not fully understood. However, it's believed to work by depleting a brain chemical called dopamine in certain areas. By regulating dopamine levels, valbenazine helps to reduce the involuntary movements associated with TD.
Dosage and administration: Valbenazine comes as tablets taken by mouth, with the specific dosage determined by your doctor based on your individual needs and response to the medication.
Side effects: Like most medications, valbenazine can cause side effects. Some potential side effects include:
- Drowsiness
- Dizziness
- Headache
- Fatigue
- Depression
- Anxiety
- Akathisia (inner restlessness that can cause an urge to move)
- Parkinsonism symptoms (tremors, stiffness, slow movement)
It's important to discuss any potential side effects with your doctor and report any you experience during treatment.
