Alka Seltzer Original 10 & 20 Effervescent Tablets

Alka Seltzer Original is a trusted, dual-action remedy designed to provide rapid relief from pain and digestive discomfort. These effervescent tablets are uniquely formulated to dissolve in water, creating a sparkling solution that is absorbed quickly by the body. By combining alka seltzer original aspirin (a proven painkiller) with an effective antacid, this treatment targets everything from tension headaches and muscular aches to heartburn and acid indigestion in one go.

Whether you need a compact pack of alka seltzer original 10 tablets for your travel kit or the larger alka seltzer original 20 tablets for the family medicine cabinet, the fizzing action ensures the medicine starts working as soon as it reaches your stomach. What does Alka Seltzer do? It provides a multi-symptom approach to recovery, making it a staple for those suffering from overindulgence or everyday pain. While highly effective, it is important to be aware of potential alka seltzer original side effects, such as mild stomach irritation, particularly if you have a history of sensitivity to aspirin.

Key Features:

  • Dual Action: Relieves pain while neutralising excess stomach acid.
  • Fast Absorption: Effervescent formula enters the bloodstream quicker than standard pills.
  • Versatile Relief: Effective for headaches, migraines, period pain, and toothaches.
  • Digestive Support: Quickly calms heartburn, upset stomach, and acid indigestion.
  • Flexible Sizing: Available in alka seltzer original 10 tablets and 20 tablets packs.
  • Easy to Take: Simply dissolve in water—no need to swallow large capsules.

Ingredients:

Alka Seltzer Original contains three active ingredients: Aspirin (Acetylsalicylic acid) 324mg, Sodium Bicarbonate 1744mg, and Citric Acid 965mg. When dissolved in water, these ingredients react to form sodium citrate, which buffers stomach acid while the alka seltzer original aspirin works to block pain signals throughout the body.

How to Use:

  • Dissolve two tablets in a 200ml glass of water.
  • Drink the entire solution once the tablets have fully fizzed and dissolved.
  • Adults (16+): Take 2 tablets every 4 hours if needed. Do not exceed 8 tablets in 24 hours.
  • Do not take on an empty stomach if you are prone to indigestion.
  • Safety: Not suitable for children under 16 due to the risk of Reye’s syndrome. Consult a pharmacist if you are concerned about alka seltzer original side effects or drug interactions
