Can I take Lansoprazole and Ibuprofen together?

Drug interaction guide

Lansoprazole is often prescribed alongside ibuprofen specifically to protect the stomach. Ibuprofen can irritate the stomach lining and cause ulcers, while lansoprazole reduces stomach acid to prevent this damage. There is no harmful interaction between the two; rather, they are frequently used together for safety.

Why this happens

Ibuprofen (an NSAID) inhibits prostaglandins that protect the stomach lining. Lansoprazole (a proton pump inhibitor) reduces the production of gastric acid, which lowers the risk of stomach irritation or ulcers caused by the ibuprofen.

It is safe to take these together. In fact, if you are taking ibuprofen long-term, your doctor may have prescribed lansoprazole specifically to protect your stomach. Always take ibuprofen with food to further reduce the risk of indigestion.

Asthma

Do not take ibuprofen if you have asthma, as it can cause a life-threatening worsening of your breathing or a severe allergic reaction.

Stomach ulcers or bleeding

Avoid ibuprofen if you have ever had a stomach ulcer, perforation, or bleeding, as it can cause serious damage to the stomach lining.

Pregnancy (third trimester)

Do not take ibuprofen if you are more than 6 months pregnant, as it can cause serious heart and kidney problems in the unborn baby and complications during birth.

Severe diarrhoea

Lansoprazole can increase your risk of serious bowel infections. If you develop severe or persistent watery diarrhoea, or a fever, contact your doctor immediately and do not take anti-diarrhoeal medicine.

Lupus (SLE) or skin reactions

Contact your doctor if you develop a skin rash, especially in areas exposed to the sun, as lansoprazole can cause a rare but serious autoimmune skin reaction.

Alcohol

It is best to avoid or strictly limit alcohol while taking ibuprofen. Combining alcohol with non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen increases the risk of irritation to your stomach lining and can lead to stomach ulcers or bleeding.

It is best to avoid or strictly limit alcohol while taking lansoprazole. Alcohol increases the amount of acid your stomach produces, which can make your symptoms worse and counteract the effects of the medicine.

Food (General)

It is recommended to take ibuprofen with food or a glass of milk to reduce the risk of stomach upset or indigestion.

Caffeine (Coffee, Tea, Energy Drinks)

Caffeine can increase the production of stomach acid. This may reduce the effectiveness of lansoprazole in treating conditions like acid reflux or stomach ulcers, and may worsen the stomach-irritating effects of ibuprofen.
