What is an expected side effect of nitroglycerin?

Explanation:
Nitroglycerin dilates blood vessels by releasing nitric oxide, which relaxes smooth muscle. This vasodilation includes the vessels in the head, so cerebral arteries and veins widen and blood flow to the brain increases, producing a throbbing headache. This headache is a very common, expected response to nitrate therapy, especially soon after taking a dose. Patients often learn to anticipate it and manage it with rest or mild analgesia as advised, since it tends to lessen with continued use or dose adjustment. While dizziness or lightheadedness from lowered blood pressure can occur, and rashes are not typical, the classic, anticipated adverse effect is a headache.
