13 Omeprazole Alternative Drugs Best for Acid Reflux

Omeprazole is one of the most commonly prescribed drugs in the UK, mainly used for the treatment of gastro-oesophageal reflux disease (GORD) with symptoms such as heartburn caused by stomach acid, which rises from the stomach into the oesophagus (the tube that connects your mouth and stomach). In this post, I will discuss different Omeprazole alternative drugs available for the public to buy and options for prescription-only medications. Additionally, the following will be reviewed: 

  • classification of omeprazole
  • classification of omeprazole alternative drugs
  • licensed use of omeprazole and omeprazole alternative drugs
  • availability of omeprazole over the counter, and finally
  • options for omeprazole alternative drugs available without a prescription and on prescription

Omeprazole and alternatives: drug classification

Omeprazole belongs to a group of medication called proton pump inhibitors (PPIs). PPIs are the most effective group of drugs that suppress the production of acid in the stomach. Omeprazole alternative drugs, discussed in this post, belong to one of the following class:

  • proton pump inhibitors (PPIs)
  • H2-receptor antagonists (H2-blockers)
  • antacids

Omeprazole alternative drugs are available as:

  • general sale list medicines (GSL),
  • pharmacy-only medicines (P) or
  • prescription-only medication (POM)

GSL medicines can be sold in any shop or supermarket. P medicines, on the other hand, can only be purchased from the pharmacy under the supervision of a pharmacist, this includes online pharmacies. POM drugs can only be prescribed by a doctor or another qualified prescriber.

Is Omeprazole available over the counter without prescription?

Omeprazole can be purchased over the counter without a prescription. Omeprazole 10mg tablets are classified as P medicine.

Pharmacy chains such as Boots and Lloyds sell their own branded version of Omeprazole named ‘Boots Acid Reflux tablets’ and ‘Heartburn relief’ (Lloyds Pharmacy). In 2019 a new product containing Omeprazole was launched. Pyrocalm Control is licensed as GSL medicine. Each gastro-resistant tablet of Pyrocalm Control contains 20mg of omeprazole.

Omeprazole 20mg is widely prescribed in the UK. Omeprazole 40mg tablets or capsules can only be obtained on prescription.

Omeprazole alternative drugs: over the counter alternatives

1. Nexium Control as omeprazole alternative drug

Omeprazole alternative: Nexium Control

Nexium Control is the closest omeprazole alternative available over the counter, without a prescription. Nexium Control belongs to the same class of drugs as omeprazole – proton pump inhibitors. Nexium Control comes in two different pack sizes: 7 and 14 tablets.

Pantoloc Control is available in two different pack sizes: 7 and 14 tablets. Short term use of pantoprazole in the treatment of gastro-oesophageal reflux disease demonstrated similar effectiveness to other PPIs such as omeprazole and esomeprazole (Dias, 2009).

The recommended daily dose is one tablet per day (daily dose: 20 mg pantoprazole).

4. Ranitidine as omeprazole alternative drugRanitidine as Omeprazole alternative

We are now moving away from PPIs. Ranitidine belongs to a group of medication called H2 receptor antagonists (H2 receptor blockers). H2 receptor antagonists differ from PPIs in chemistry and work in a different way to suppress acid production. Ranitidine is effective in the management of heartburn and indigestion symptoms; however, PPIs are superior (more effective) in the treatment of GORD symptoms (Sigterman et al., 2013) than ranitidine.

Ranitidine is available under different brand names, including most known: Zantac. Supermarkets and chain pharmacies sell their own ‘versions’ of ranitidine. Each over the counter ranitidine product contains 75mg of ranitidine per tablet. Ranitidine is considerably cheaper than PPIs available over the counter.

Where to buy ranitidine?

Most pharmacies and larger supermarkets stock ranitidine. Over the counter ranitidine products contain 75mg of ranitidine per tablet.

Ranitidine over the counter: recommended daily dose
  • Over the counter ranitidine is licensed for adults and adolescents from 16 years of age.
  • One tablet (75mg of ranitidine) should be taken on the onset of symptoms.
  • No more than two tablets should be taken in 24 hours.
Ranitidine recalls: supply issues

In recent months most ranitidine 75mg products including Zantac, most supermarket own labeled versions of ranitidine and prescription-only ranitidine were subject to a number of recalls due to possible contamination with N-Nitrosodimethylamine (NDMA), which is classified as ‘probable human carcinogen‘. This is a global issue with a number of ranitidine products in the USA containing above the acceptable daily intake of NDMA. In the UK investigation is being conducted by The Medicines and Healthcare Regulatory Agency (MHRA). This means the supply of ranitidine products will be disrupted in the coming months. You can learn more about ranitidine recalls and the link between NDMA and cancer in my separate post.

Some of you may ask: why PPIs are more effective than H2-receptor antagonist?

The difference in effectiveness comes from different mechanisms of action of PPIs and H2 receptor antagonists. In plain language, H2 receptor antagonists suppress acid production by blocking only one pathway of acid production. PPIs, on the other hand, block proton pump, which plays a role in the final part of acid secretion. This mechanism of action makes them more effective than H2 receptor antagonists.

5. Antacids as over the counter omeprazole alternative

Antacids are least effective as compared to two other groups of drugs discussed so far. However, antacids provide fast, short term relief from symptoms of heartburn by neutralising acid in the stomach.

Antacid can be purchased from pharmacies and other outlets. There is a number of antacid products available on the market. Antacids come in different forms, for example as chewable tablets and most popularly as a liquid formulation.

Popular brands of antacid products include:

  • Gaviscon, available as chewable tablets, and liquid
  • Rennie range of heartburn and indigestion chewable tablets
  • Tums chewable tablets
  • Peptac liquid

Oral solution of Ranitidine is prescribed for babies (young population) or patients with swallowing difficulties. 

Other H2 blockers available on prescription include: 

11. Cimetidine

12. Famotidine

13. Nizatidine

The above three drugs are not commonly prescribed in the UK.

Lifestyle changes

Lifestyle changes such as weight loss can reduce episodes of heartburn. Other lifestyle modifications to consider include:

  • avoid foods that cause acid reflux
  • reduce alcohol consumption
  • reduce coffee consumption
  • stop smoking

Anyone experiencing symptoms of heartburn for longer than three weeks should consult their GP. Patients should be aware of other symptoms needed GP referral, such as weight loss (for no reason), frequent episodes of feeling sick (NHS, 2017), and other symptoms. Visit the NHS website for more information on indigestion.

Always read the product information leaflet.
