This phenomenon occurs because the vasodilatory effect of nitrates causes the blood vessels in the brain to dilate as well, leading to increased intracranial pressure and subsequent headaches.

Headaches associated with nitrate use can be quite common, particularly at the initiation of therapy or with dose increases.
