Which option is NOT used for migraine prophylaxis?

The main idea is which drug classes are effective for preventing migraine attacks. Prophylaxis relies on medicines that dampen neuronal excitability or stabilize vascular function to reduce how often migraines occur. Antihypertensives work because they help modulate vascular tone and lower the propensity for migraine-related vascular changes. Beta-blockers such as propranolol and metoprolol are classic options, and calcium-channel blockers like verapamil are used in some cases as well. Antiseizure medications help by decreasing neuronal hyperexcitability. Topiramate is a common preventive agent for migraines, acting on multiple channels and systems to lessen attack frequency. Valproate is another option but comes with more safety considerations, especially in women of childbearing potential. Botulinum toxin injections are approved for chronic migraine prevention. When injected into head and neck muscles, it appears to reduce the release of pain-mediating neurotransmitters, decreasing the number of migraine days in patients with many monthly headaches. Antibiotics, on the other hand, are not used for migraine prophylaxis. They treat infections and have no mechanism or proven benefit in preventing migraine attacks.
