• Labetalol is a beta blocker, which treats hypertension and it would not be used to treat any side effects of nitroglycerin

• Diphenhydramine is an antihistamine and is used to treat allergies and allergic reactions. It would not prevent headaches or other side effects associated with nitroglycerin
