Alka-Seltzer XS is a fast-acting effervescent tablet designed to relieve headaches, migraines, and other pain associated with colds and flu. It contains a combination of paracetamol (a pain reliever and fever reducer), aspirin (an anti-inflammatory), and caffeine (a stimulant that enhances the effects of pain relievers). When dissolved in water, the tablets quickly deliver pain relief while also helping to reduce fever and inflammation. Alka-Seltzer XS is suitable for adults and children over 16 years old, providing rapid relief for a range of aches and pains.
