While Flunarizine helps prevent migraines over time, it does not treat active attacks. Aceclofenac and Paracetamol may be insufficient for sudden, severe episodes. For acute relief, specific migraine rescue medications called triptans (such as Sumatriptan or Rizatriptan) are often much more effective. Your doctor might also suggest adding an antiemetic (like Domperidone) to enhance painkiller absorption. Please consult your physician to prescribe a triptan for sudden attacks, and to review if your daily Flunarizine needs a dose adjustment or a switch to alternative preventives like Propranolol or Topiramate. Avoid frequent painkiller use to prevent rebound headaches.
