Medications may be used in early hemifacial spasm (when spasms are mild and infrequent) or in patients who decline botulinum toxin injection. Use medications in patients with noncompressive lesions and early idiopathic hemifacial spasm. Response to medication varies but can be satisfactory in early or mild cases. The most helpful agents are carbamazepine and benzodiazepines (eg, clonazepam). Often, medication effects attenuate over time, necessitating more aggressive treatment.
