For frequent migraines, your daughter needs a dual approach supervised by her doctor. 1. Acute Relief: Since OTC painkillers and Migranil are ineffective or unsafe long-term, Triptans (like Sumatriptan or Rizatriptan) are highly effective prescription alternatives to stop an active attack. 2. Prevention: To reduce attack frequency from every 10 days, daily preventive medications like Beta-blockers (e.g., Propranolol), Tricyclic Antidepressants (e.g., Amitriptyline), or Anticonvulsants (e.g., Topiramate) can be used. Lifestyle changes, including maintaining regular sleep and food triggers tracking, are also beneficial. Please consult a neurologist to safely tailor her treatment plan.
