What should patients do after using sublingual Nitroglycerin tablets?

Patients using sublingual Nitroglycerin tablets should avoid eating or drinking immediately after placement. This precaution is important because consuming food or beverages can interfere with the dissolution and absorption of the medication in the sublingual area, potentially reducing its effectiveness in providing rapid relief from angina attacks. The sublingual route allows the drug to enter the bloodstream quickly, and any interference could delay the onset of action. By refraining from eating or drinking right after the tablet is placed under the tongue, patients help ensure the medication is properly absorbed and reaches therapeutic levels in a timely manner.
