Many drugs can induce acute headache, including nitroglycerin,

agents (beta blockers, calcium channel blockers,
erectile dysfunction pill 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 citrate sildenafil ups).

Drug-induced aseptic meningitis, a rare occurrence, has numerous possible
causes, including NSAIDs, antibiotics (e.g., impotence treatment
,
sulfasalazine, cephalosporins, ciprofloxacin, isoniazid, and penicillin),
intrathecal drugs and diagnostics (e.g., antineoplastic agents such as
methotrexate and cytarabine; gentamicin; corticosteroids; spinal anesthesia;
baclofen; repeated iophendylate for myelography; and radiolabeled albumin);
intraventricular chemotherapy; intravenous immunoglobulin; vaccines (polio;
measles, mumps, and rubella; and hepatitis B); and some other drugs, such as
impotence help
, muromonab-CD3, and ranitidine.⁴³

The clinical presentation of drug-induced aseptic meningitis is the same as
that of viral meningitis. Cerebrospinal fluid findings are the same as those in
viral meningitis, except for a neutrophil predominance; however, in cases
induced by intravenous immunoglobulin, eosinophils are present.
