Review confirms small cardiovascular risk with daily doses at or above 2,400 mg
The CMDh has endorsed by consensus updated advice on the use of high-dose ibuprofen. This follows a review carried out by EMA’s Pharmacovigilance Risk Assessment Committee (PRAC), which confirmed a small increased risk of cardiovascular problems, such as heart attacks and strokes, in patients taking high doses of ibuprofen (at or above 2,400 mg per day). The review clarifies that the risk with high-dose ibuprofen is similar to the risk seen with some other non-steroidal anti-inflammatory drugs (NSAIDs), including COX-2 inhibitors and diclofenac.
No increase in cardiovascular risk is seen with ibuprofen at doses of up to 1,200 mg per day, which is the highest dose generally used for over-the-counter (OTC) preparations taken by mouth in the European Union (EU).
To minimise the cardiovascular risk, high doses of ibuprofen (2,400 mg per day or higher) should be avoided in patients with serious underlying heart or circulatory conditions, such as heart failure, heart disease and circulatory problems or in those who have previously had a heart attack or stroke.
In addition, doctors should carefully assess a patient’s risk factors for heart or circulatory conditions before initiating long-term treatment with ibuprofen, particularly if high doses are required. Risk factors include smoking, high blood pressure, diabetes and high blood cholesterol.
The review also looked at data on the interaction between ibuprofen and low-dose aspirin when the latter is taken to reduce the risk of heart attacks and strokes. Laboratory studies have shown that ibuprofen reduces the blood-thinning effects of aspirin. However, it remains uncertain whether long-term use of ibuprofen in clinical practice reduces the benefits of low-dose aspirin in preventing heart attacks and strokes. Occasional use of ibuprofen should not affect the benefits of low-dose aspirin.
The updated advice on the cardiovascular risk of high-dose ibuprofen will be included in the product information of ibuprofen medicines, along with information on the interaction between ibuprofen and aspirin.
The recommendations for ibuprofen also apply to dexibuprofen, a medicine similar to ibuprofen. A high dose of dexibuprofen is a dose at or above 1,200 mg per day.
As the CMDh has now agreed the PRAC advice by consensus, changes to the product information for ibuprofen- and dexibuprofen-containing medicines will be implemented by the Member States where the medicines are authorised, according to an agreed timetable.
