Product Description

what are Alka-Seltzer Original tablets and what are they used for

Alka-Seltzer Original Tablets provide fast relief of heartburn, upset stomach, acid indigestion with headache or body aches from this effervescent antacid and pain reliever that has been around for more than 80 years. Unlike other antacids, such as Tums or Mylanta, H-2 blockers such as Pepcid, and PPIs like Prilosec and Nexium, Alka-Seltzer Original contains an analgesic for pain accompanied by heartburn and acid indigestion.

There’s usually no need to see a GP about indigestion. There are some things you can do at home.

  • cut down on tea, coffee, cola or alcohol
  • prop your head and shoulders up in bed – this can stop stomach acid coming up while you sleep
  • lose weight if you’re overweight
