Common side effects of nitroglycerin include

• A. Weight gain
• B. Hair loss
• C. Insomnia
• D. Headache and hypotension

Answer: (D)

Vasodilatory effects of nitroglycerin produce the most common adverse effects you’ll see. By dilating veins (and to a lesser extent arteries), nitroglycerin lowers venous return and overall blood pressure. This vascular dilation especially triggers headaches, since dilating cerebral vessels can stimulate pain pathways in the meninges. The same systemic vasodilation leads to hypotension, which can cause dizziness or lightheadedness, particularly when moving to a standing position. The other options don’t fit this typical pattern. Weight gain isn’t a usual nitroglycerin side effect, hair loss isn’t associated, and insomnia isn’t commonly reported with nitroglycerin. Therefore, the description of headache and hypotension best captures the common adverse effects.
