16 Best Gaviscon Alternative Products

Best Gaviscon alternative products and drugs - summary

Gaviscon range of products is probably the most known brand of antacids in the UK. There are, however, several alternative products and drugs which can be used to help with symptoms of heartburn and indigestion.

Today I will review 16 best Gaviscon alternative products and medicines. I will briefly discuss what Gaviscon is to get a better understanding of alternative treatments.

I will also talk about:

  • Gaviscon and other antacids mechanism of action
  • Gaviscon alternative products: antacids (liquid and chewable forms)
  • Gaviscon alternative products: proton pump inhibitors (PPIs)
  • Gaviscon alternative drugs: h2-receptor antagonists

How Gaviscon and Alternative Antacids Work?

Gaviscon is a brand of products, commonly referred to as ‘antacids’ used in the management of acid reflux, also known as heartburn and indigestion. Heartburn happens when acid escapes from the stomach back to the oesophagus (a long tube that connects the mouth and stomach), causing the following symptoms commonly:

  • Burning sensation in the lower or middle chest area
  • An unpleasant burning and irritation at the back of the throat

Symptoms of the heartburn are usually present after a meal and may get worse when lying down.

Ongoing symptoms of heartburn have an umbrella term of Gastroesophageal Reflux Disease (GERD).

Heartburn causes - acid 'escaping' stomach

Antacids neutralize stomach acid and therefore help with symptoms caused by the excess of acid. Additionally, antacids may contain alginates (sodium alginate), which form a ‘raft’ preventing acid from leaving the stomach. Antacids usually contain sodium bicarbonate or potassium bicarbonate as an active ingredient.

Differences between Gaviscon products

Gaviscon range of products include:

  • Gaviscon Original
  • Gaviscon Advance
  • Gaviscon Double Action

The table below shows the differences between main Gaviscon products focusing mainly on the main active ingredients present in the formulation of each product.

Range Active ingredients Forms available
Gaviscon Original Calcium carbonate, sodium alginate, sodium bicarbonate Oral suspension, chewable tablets
Gaviscon Advance Potassium bicarbonate, sodium alginate Oral suspension, chewable tablets,
Gaviscon Double Action Calcium carbonate, sodium alginate, sodium bicarbonate Oral suspension, liquid sachets, chewable tablets

It can be concluded from the above table that Gaviscon range of products contains a combination of:

  • Sodium alginate: forms a protective layer in the gut. In the presence of sodium bicarbonate, sodium alginate creates a ‘raft’ that is present on the top of the stomach content, preventing acid reflux.
  • Sodium bicarbonate: used as an antacid to neutralize stomach acid.
  • Calcium carbonate: used as an antacid to neutralize stomach acid.

Gaviscon Advance vs Gaviscon Double action vs Gaviscon Original, what is the difference?

Gaviscon Advance contains more sodium alginate than Gaviscon Original making it a ‘stronger antacid’. Gaviscon Double Action contains sodium alginate and additionally two other antacids, as compared to Gaviscon Advance, which contains sodium alginate and potassium bicarbonate.

Gaviscon Double Action contains a double amount of sodium alginate as compared to Gaviscon Original.

Gaviscon alternative products: antacids

Products, which are alternatives to Gaviscon, contain a combination of one or more of the same ingredients.

Gaviscon alternative Liquid Antacid

1. Peptac as Gaviscon alternative

Peptac is one of the best-priced liquid antacid products which can be used for symptoms of heartburn and indigestion.

Peptac comes in 500ml bottles in two flavors:

  • Peptac Peppermint liquid
  • Peptac Aniseed liquid

Peptac contains the following active ingredients:

  • Sodium Bicarbonate
  • Sodium Alginate
  • Calcium Carbonate

This combination of active ingredients is the same as one found in Gaviscon Original and Gaviscon Advance.

Peptac can be bought from most high street pharmacies, although it is usually kept as part of dispensing stock rather than a product which is shown for sale. When priced right, Peptac can be purchased for around £4, making it one of the best-priced liquid antacids on the market.

Other products which are the same as Peptac and produced by the same manufacturer, but marketed by different companies include:

  • Acidex Oral Suspension
  • Tesco Heartburn & Indigestion relief
  • Boots Heartburn Relief Peppermint Flavour
  • LloydsPharmacy Heartburn and Indigestion Liquid
  • Rennie Liquid Heartburn Relief Oral Suspension
  • LloydsPharmacy Heartburn and Indigestion Liquid

 2. Milk of Magnesia

Milk of Magnesia (Phillips) is a popular product, which can be used as an antacid to manage the symptoms of heartburn and indigestion. Additionally, Milk of Magnesia is used to help with stomach discomfort, flatulence (gas) and as a laxative to help with constipation.

Milk of Magnesia does not contain the same active ingredient(s) as Gaviscon; however magnesium hydroxide has similar (almost equal) effectiveness to neutralise stomach acid as sodium bicarbonate (eMC, 2020), which is one of the ingredients in Gaviscon range.

3. Maalox

Maalox contains aluminum hydroxide and magnesium hydroxide; both used to help with heartburn and indigestion. The main active ingredients are different from active ingredients found in the Gaviscon range. Maalox is not commonly dispensed in high street pharmacies or sold as part of regular stock.

Some pharmacies may agree to order Maalox from pharmaceutical wholesalers on an individual basis for the same or next-day delivery. Alternatively, Maalox can be purchased online, for example, Amazo.co.uk (see link below).

4. Maalox Plus as Gaviscon alternative

Similarly to Maalox, Maalox Plus contains aluminium hydroxide and magnesium hydroxide which act as antacids to neutralise stomach acid. Maalox Plus contains a third active ingredient – simeticone. Simeticone is an antiflatulent/antifoaming agent, which is used to help with bloating and discomfort caused by trapped wind.

Patients who experience symptoms of heartburn and bloating (trapped wind) may find this alternative product even more effective than Gaviscon range of products. Maalox Plus is not usually kept as a part of the regular over-the-counter stock.

It is possible to make a request to order Maalox Plus in a high street pharmacy, as Maalox Plus is stocked by main UK pharmaceutical wholesalers. Alternatively, see the link below to get Maalox Plus from Amazon.co.uk

Gaviscon alternative products: Chewable tablets

Although more convenient than liquid preparations, chewable antacid tablets work slower and are less effective in neutralizing stomach acid (iffgd, 2019).

Neferthen lees patient may get sufficient response from chewable forms of antacids. Two most popular brands of chewable antacid alternative to Gaviscon range, are Rennie range of antacid tablets and Tums.

5. Rennie

Rennie range of antacid tablets contains calcium carbonate and magnesium carbonate. Although the combination of active ingredients is not the same as with Gaviscon range of liquid antacid and tablets, Rennies contain commonly used antacid compound and will help with symptoms of indigestion and heartburn.

Rennies are commonly available over the counter in supermarkets and pharmacies.

6. Tums

Tums are standing out from the crown of antacid products with the range of unique flavours for their variety including assorted fruit and assorted berries flavours with advertised ‘delicious taste’. Tums contain calcium carbonate as an active ingredient.

7. Bisodol

Bisodol brand of antacid tablets is part of the Rannie range. Bisodol chewable tablets contain three active ingredients: Calcium Carbonate, Magnesium Carbonate, and Simeticone.

In addition to management of heartburn and indigestion Bisodol chewable tables help to manage trapped wind, thanks to simeticone, which is included in the formulation.

8. ENO

ENO offers an alternative form of antacid medication not only to Gaviscon, but also other heartburn drugs. ENO comes in the form of powers which are mix with water and consumed. ENO contains sodium carbonate, sodium bicarbonate, and citric acid, which can be used in the relief of heartburn and indigestion.

[amazon link=”B00DS79ATO” title=”ENO powders can be bought online” link_icon=”amazon” /], high street pharmacies do not stock this product.

Gaviscon alternative products: proton pump inhibitors (PPIs)

Proton pump inhibitors (PPIs)are the most effective drugs in the management of heartburn/indigestion. PPIs work in a completely different way to antacids such as Gaviscon. PPIs stop the production of stomach acid (rather than neutralizing it), making them superior to Gaviscon and other antacid products.

When used for uncomplicated heartburn, all PPIs control symptoms with a single dose. Symptom control is usually long-lasting (for up to 24 hrs),  as opposed to antacid, which needs to be used a few times a day.

PPIs are available over the counter, and on prescription with the latter option giving a wider choice of PPIs in the management of heartburn and indigestion.

Over the counter PPIs include the following drugs:

  • Esomeprazole
  • Omeprazole
  • Pantoprazole

Facts to consider before using PPIs

Delayed onset of action

The general advice for PPIs is that it can take 2-3 days to see full symptom control, although most patients should see benefits of treatment within one hour of taking a PPI.

Age restrictions

All PPIs available without a prescription over the counter are restricted to adults aged 18 and over. When prescribed, PPIs can be used by the younger population.

Drugs interaction



PPIs interact with several drugs. Check the product information leaflet for more details or speak to the pharmacist before use.

Side effects

Use of proton pump inhibitors is associated with more common side effects as compared to antacids such as Gaviscon.

Common side effects may include:

  • Headaches
  • Abdominal pain
  • Constipation
  • Diarrhea
  • Flatulence
  • Nausea/vomiting

Side effects

Limit on the duration of treatment

Patients who do not achieve relief of symptoms within two weeks of starting the treatment should see advice from their GP. Over-the-counter proton pump inhibitors are used for the short-term treatment of heartburn and indigestion.

Gaviscon alternative products: H2-receptor antagonists

15. Ranitidine

H2-receptor antagonists such as ranitidine as effective in reducing stomach acid and controlling the symptoms of indigestion. The only H2-receptor antagonist which was available over the counter was ranitidine 75mg tablets, also sold under the brand name Zantac 75 Relief.

All ranitidine products (over-the-counter and prescription-only) have been recalled due to safety concerns. Ranitidine is currently undergoing investigation by the Medicines and Healthcare products Regulatory Agency (MHRA) into its safety. Ranitidine will not be available for sale in the UK is a foreseeable future.

There is plenty of alternatives to ranitidine; some options were discussed in this post. None of any other H2-receptor antagonists is available without a prescription in the UK.

16. Prescription options for H2-receptor antagonist

Prescription-only options forH2-receptor antagonist include:

  • Cimetidine
  • Nizatidine
  • Famotidine

All the above drugs are intermediately out of stock due to increased demand caused by lack of ranitidine on the market.


Patients have a great choice of Gaviscon alternative medicines. There is a wide selection of alternative antacid products which come in the form of liquids and tablets.

Peptac liquid (available also under different brand names, see post for more details) resembles the closest alternative to Gaviscon as it contains a combination of the same active ingredients. Patients who suffer from indigestion/heartburn may, however, benefit from the use of any antacids discussed in this post.

Proton pump inhibitors are the most effective in the management of heartburn and indigestion symptoms. PPIs became readily available to patients with most supermarkets, pharmacies and online vendors selling one or more drugs in this category. PPIs should only be used as a short term treatment of acid reflux.

Patients who experience symptoms of heartburn/indigestion ongoingly or patients who fail to respond to treatment should contact their GP for advice. When prescribed, PPIs can be used ongoingly, under the care of a GP.
