Should I take Naproxen And Omeprazole Together?

Naproxen and Omeprazole: should I take it together?

Naproxen and Omeprazole are common drugs prescribed in the UK. Individually both drugs are used in the treatment of different conditions; however, many patients who are prescribed Naproxen get Omeprazole prescribed at the same time. Why are Naproxen and Omeprazole prescribed together?

What Is Naproxen Used For?

Naproxen belongs to a group of drugs called Non-Steroidal Anti-Inflammatory Drugs (NSAIDs).

Other common drugs that belong to the NSAIDs class of drugs include:

  • Aspirin
  • Ibuprofen
  • Diclofenac
  • Celecoxib
  • Etoricoxib
  • Indomethacin

What Is Naproxen Used For?

NSAIDs stop the production of prostaglandins, a group of chemicals that contribute to symptoms of inflammation and pain; however, prostaglandins also have a broader role in the human body.

Production of prostaglandins increases in response to injury or infection.

By reducing the production of prostaglandins, NSAIDs reduce pain and inflammation.
Naproxen is indicated in the following conditions (NICE, 2019):

  • Pain and inflammation of musculoskeletal nature
  • Dysmenorrhoea (painful period pains)
  • Onset of gout
  • Management of migraines

What Is Omeprazole Used For?

What Is Omeprazole Used For

Omeprazole belongs to a group of drugs called Proton Pump Inhibitors (PPIs).

This group of drugs is used mainly in the treatment of acid reflux and Gastro-Oesophageal Reflux Disease (GORD).

Other uses include:

  • Treatment and prevention of gastric and duodenal ulcers
  • Prevention of complications in patients who take NSAIDs continuously, who have a history of NSAID-associated duodenal, gastric ulcers or gastric lesions, or symptoms of dyspepsia
  • Zollinger–Ellison syndrome
  • Treatment of Helicobacter pylori, bacterial infection together with a combination of two antibiotics

Omeprazole is one of the most commonly prescribed drugs in the UK.

Why Are Naproxen And Omeprazole Prescribed Together?

Treatment with NSAIDs, such as Naproxen, is associated with a number of possible side effects. Some of the most common gastrointestinal side effects related to Naproxen use include:

  • Peptic ulcers
  • GI bleeding or perforation (a hole)
  • Heartburn, dyspepsia, abdominal discomfort

As previously mentioned, prostaglandins have a number of roles in the body. Some prostaglandins are present in the stomach lining, where they inhibit acid secretion and stimulate mucus production, thus having a protective function (Wallance, 2008).

Since Naproxen stops the production of prostaglandins, patients who take it are at higher risk of gastrointestinal complications such as GI bleeding, heartburn, and ulcers.

Proton Pump Inhibitors, such as Omeprazole, are prescribed alongside Naproxen to minimize the stomach acid secretions and reduce the risk of possible side effects.

Do You Need To Take Omeprazole while On Naproxen?

Patients are generally advised to take Naproxen with or after food to minimize the risk of stomach side effects. This is a preferred method of administration.

Interestingly, no evidence shows that taking analgesics with food minimizes adverse effects (Moore et al., 2015).

A systemic review (a review comparing a large number of studies) on the effect of foods on NSAIDs and other drugs concluded that taking Naproxen with food delays the absorption of the drug and prolongs the time it takes to work.

Food does not affect how much drug is absorbed (gets into the body) (ibid).

Delayed onset of action may not be preferable when a drug is taken to manage acute conditions such as migraine or period pains.
Some patients will be recommended to take Omeprazole or another PPI when prescribed Naproxen; see list below.

Official Recommendation On The Use Of Omeprazole When Naproxen Is Prescribed

The official NICE guideline (NICE, 2019) recommends using gastro-protection (Omeprazole) when NSAIDs such as Naproxen are prescribed in patients who:

  • Are at risk of gastrointestinal side effects, for example, patients needing a long-term treatment with NSAIDs who experience indigestion from standard NSAIDs such as Ibuprofen

Patients who are at risk of side effects associated with the use of NSAIDs include (ibid):

  • Patients aged over 65
  • Patients with a history of ulcers or stomach bleeding
  • Patients prescribed a high dose of NSAIDs
  • Patients taking other drugs which can contribute to gastrointestinal side effects, for example, a common class of antidepressants SSRIs (e.g., Fluoxetine, Citalopram )
  • Patients who smoke or drink alcohol a lot
  • Patients who experienced side effects with NSAIDs in the past
  • Patients who require a long treatment with NSAIDs

Does Naproxen Interact With Omeprazole?

Naproxen does not interact with Omeprazole. Both drugs can be taken at the same time.

What Are Naproxen Gastro-Resistant Tablets?


Most commonly, Naproxen is prescribed as immediate-release tablets. Naproxen tablets are also available in gastro-resistant (enteric-coated) tablets. Naproxen gastro-resistant formulation is designed to prevent the tablet from breaking down in the stomach and thus minimize the risk of side effects.

Limited studies exist to show the advantages of Naproxen gastro-resistant tablets over immediate-release tablets. Only one study of over 300 patients treated with Naproxen gastro-resistant tables showed better stomach tolerability (reduced number of side effects) than immediate-release tablets in patients with osteoarthritis rheumatoid arthritis (Caldwell & Roth, 1994).

Theoretically, it is possible to increase the risk of lower gastrointestinal side effects since gastro-resistant tablets are dissolved further along the GI tract (Davies, 1999). Finally, prescribing a combination of immediate-release Naproxen with Omeprazole is much more cost-effective than prescribing Naproxen gastro-resistant tablets, which are several times more expensive.

Alternative Options To Omeprazole

Omeprazole is the most prescribed PPI in the UK and one of the most prescribed drugs overall. Patients, however, may be co-prescribed a different PPI, for example, Lansoprazole or Esomeprazole.

Esomeprazole can be purchased over the counter without a prescription from supermarkets and pharmacies. Read Omeprazole alternative drugs or Lansoprazole vs Omeprazole to learn more about different PPIs.

H2 receptor antagonists, such as ranitidine, can also be used; however, with a number of recalls and ongoing investigations into the safety of ranitidine, it is unlikely to get this drug in the UK.

Conclusion On Taking Naproxen And Omeprazole Together

To conclude, Naproxen and Omeprazole do not have to be co-prescribed to all patients. A certain group of ‘at at risk’ patients needs Omeprazole treatment when prescribed Naproxen.

Naproxen should preferably be taken with food (product license). Always follow the directions of the prescriber.

Quick FAQ

What can I take with naproxen to protect my stomach?
Osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis are treated with a combination of lansoprazole and Naproxen. The lansoprazole in this drug helps lower the risk of stomach ulcers in people taking an NSAID.
What should I not mix with naproxen?
It is not advised to take Naproxen, Ibuprofen, or aspirin within 8-12 hours of the gap from each other. Also, cold and cough medicines are not recommended to be taken together with Naproxen.
Is naproxen hard on the stomach?
Naproxen may cause ulcers, bleeding, or holes in the stomach or intestine. These problems or symptoms may worsen and, in extreme cases, may cause death.
