Product description

Water soluble tablets for the rapid relief of aches and pains.

Alka-Seltzer XS has been formulated using aspirin and paracetamol, which when working together provide rapid and effective relief from headaches, migraines, period pain, toothache, and sore throats. These water soluble tablets also provides symptomatic relief of fever, colds and flu, as well as rheumatic pain, sciatica, lumbago, fibrosis, and muscular aches and pains.

This double action tablet is rapidly absorbed into your body and distributed around your body. Alka-Seltzer XS also contains caffeine which is a mild stimulant that can perk you up if you're feeling unwell, but also improves the effectiveness of paracetamol by accelerating absorption.
