Product description

Effervescent tablets for the rapid relief of aches and pains.

Alka-Seltzer XS is an effervescent tablet that can be quickly absorbed by the body and is used to relieve migraine, headache, toothache, indigestion, heart burn and more. It functions both as a painkiller and an antacid, meaning it can calm an upset stomach. .

Alka-Seltzer XS contains the three active ingredients caffeine, paracetamol and aspirin. Caffeine is a mild stimulant that can perk you up if you're feeling unwell, but also improves the effectiveness of paracetamol by accelerating absorption. Simply place a tablet in a glass of water and drink normally. These reliable tablets will get to work instantly on your aches and pains so you can go about your day.
