Alka-Seltzer Original Information

How does Alka-Seltzer Original work?

Alka-Seltzer is an effervescent pain reliever containing aspirin. The aspirin relieves your pain and reduces inflammation.

How quickly do Alka-Seltzer tablets get results?

Alka-Seltzer Original dissolves quickly. Medicines in effervescent form don’t require time to dissolve in the stomach like other treatments, and so provide relief faster than traditional tablets.

Alternatives to Alka-Seltzer Original

Effervescent medication acts quickly, but you may prefer to take a conventional tablet. If so, consider taking Paracetamol or Ibuprofen instead. Looking to treat heartburn or indigestion specifically? Try Lansoprazole.

How do I take Alka-Seltzer Original?

Alka-Seltzer Original is an effervescent medication, which means it needs to be dissolved in water. Drop two tablets into half a glass (100ml) of water, wait for them to dissolve completely, and drink. This medication is not recommended for children under the age of 16.

How often can I use Alka-Seltzer Original?

The recommended adult dose of Alka-Seltzer Original is 2 tablets every 4 hours as needed. If that isn’t enough, your doctor may recommend a higher dosage — though you mustn’t exceed 8 tablets in 24 hours.

Alka-Seltzer Original ingredients

Alka-Seltzer Original was designed around aspirin.

The other ingredients are as follows:

Povidone, dimeticone, calcium silicate, docusate sodium, sodium benzoate (E211), sodium saccharin, natural and artificial lemon flavour, and natural and artificial lime flavour.

Does Alka-Seltzer Original produce any side effects?

Alka-Seltzer Original is very safe, which is why it’s used so widely for the relief of mild pain and indigestion, but every medication can occasionally produce side effects. In this case, potential side effects include the following:

  • Excess stomach acid secretion
  • Stomach irritation
  • Nausea
  • Vomiting
  • Heartburn
  • Stomach cramps

More rarely, users can experience gas and/or abdominal bloating. If you experience any of these effects, please cease treatment immediately and speak to a healthcare professional.
