Alka-Seltzer Original 20 Effervescent Tablets


What is Alka-Seltzer, and what is it used for?

Alka-Seltzer are tablets designed to relieve mild to moderate pain including rheumatic and muscular pain, sprains and strains, backache, nerve pain (neuralgia), migraine, headache, toothache, sore throat and period pain.

They can also be used to lower a high temperature and relieving the symptoms of colds and flu. Use these tablets when you are feeling any of the above, and want a quick relief from pain.

Aspirin, the active ingredient in Alka-Seltzer, belongs to a group of medicines called non-steroidal anti-inflammatory drugs. It works by blocking the action of an enzyme in the body called cyclo-oxygenase (COX).
