Medication Headaches
Many drugs can induce acute headache, including nitroglycerin, antihypertensive agents (beta blockers, calcium channel blockers, angiotensin-converting enzyme [ACE] inhibitors, and methyldopa), dipyridamole, hydralazine, sildenafil, histamine receptor antagonists (e.g., cimetidine and ranitidine), NSAIDs (especially indomethacin), cyclosporine, and antibiotics (especially amphotericin, griseofulvin, tetracycline, and sulfonamides).
