What are Gaviscon Advance Chewable Mint Tablets?

Gaviscon Advance Chewable Mint Tablets are a treatment designed to ease indigestion and heartburn. Just chew one or two tablets and swallow them for fast indigestion and heartburn relief on the go, without needing to measure out liquids or swallow with a drink.


What is indigestion?

Indigestion is a common problem that most people deal with at some point. It happens after you eat or drink, as excess stomach acid causes irritation to your stomach lining and food pipe. This causes unpleasant and potentially embarrassing symptoms, including:

  • Heartburn or acid reflux
  • Feeling full
  • Bloating
  • Burping or farting (wind)
  • Feeling sick or being sick


How will Gaviscon Advance Chewable Tablets relieve my indigestion?

Gaviscon Advance Chewable Tablets contain two active ingredients which can both help to ease indigestion and heartburn: sodium alginate 500mg and potassium bicarbonate 100mg. These ingredients form a type of treatment called reflux suppressants, which means that they work by forming a protective layer over your stomach contents. This layer keeps excess stomach acid from irritating your food pipe and stomach lining.


Can I take these tablets if I’m pregnant or breastfeeding?

Gaviscon Advance Tablets are suitable for use when you’re pregnant or if you’re breastfeeding. However, you should speak to your doctor or pharmacist before taking this or any other medication at these times. The amount of time you take these tablets for should be as limited as possible.


Can I take this product if I’m taking other medication?

If you’re taking any other medication, including those obtained without a prescription, you should speak to your doctor or pharmacist before taking this product. Some medications can interact when taken together, causing unwanted side effects or making your medication less effective, but a medical professional can help you to avoid this.


How to take these tablets?

Take 1 – 2 Gaviscon Advance Tablets up to 4 times a day, after meals and at bedtime. Chew the tablets thoroughly before swallowing. Do not take more than 8 tablets a day. If your symptoms haven’t improved after 7 days, speak to your doctor.


When should this product not be used?

Gaviscon Advance Tablets should not be given to children under the age of 12, unless advised to do so by your doctor. Do not take these tablets if you’re allergic to sodium alginate, potassium bicarbonate, or any of the other listed ingredients. These tablets contain sodium (salt), potassium, and calcium, so be sure to speak to your doctor or pharmacist before taking this product if you are on a low sodium, potassium, or calcium diet. This product contains aspartame, which is a source of phenylalanine, keep this in mind if you suffer with phenylketonuria.
