Is alka seltzer a NSAID

No, Alka-Seltzer is not classified as a nonsteroidal anti-inflammatory drug (NSAID). It is an over-the-counter antacid that contains sodium bicarbonate, citric acid, and sometimes aspirin, which is an NSAID. However, the primary purpose of Alka-Seltzer is to relieve heartburn, indigestion, and upset stomach rather than to provide anti-inflammatory effects. Always check the specific formulation for active ingredients, as some versions may not contain aspirin.
