Can I take Rivaroxaban and Aspirin together?

Why this happens

Both medicines work to prevent blood clots but in different ways. Rivaroxaban is an anticoagulant (blood thinner) that interferes with clotting proteins, while aspirin is an antiplatelet medicine that stops blood cells from sticking together. Using them together creates a 'double' thinning effect on the blood.

What you should do

Do not take aspirin with rivaroxaban unless your specialist doctor has specifically told you to do so (for example, if you have a heart stent). If you are prescribed both, watch closely for signs of bleeding, such as dark/tarry stools, coughing up blood, or severe bruising. Always tell your pharmacist you are on rivaroxaban before buying over-the-counter painkillers, as many contain aspirin or similar drugs like ibuprofen.

Important precautions

Bleeding risk and surgery

You must tell any doctor, dentist, or surgeon that you are taking these medicines before any procedure, as they significantly increase your risk of bleeding and may need to be stopped temporarily.

NSAID use (e.g. ibuprofen, naproxen)

Do not take anti-inflammatory painkillers like ibuprofen or naproxen while on these medicines unless specifically prescribed, as this combination severely increases the risk of dangerous internal bleeding.

Asthme

If you have asthma, aspirin can trigger a severe worsening of your symptoms or a life-threatening allergic reaction; do not take it if you have ever had a reaction to similar painkillers.

Food and drink warnings

Food (General)

You must take the 15mg and 20mg doses of rivaroxaban with food. This helps your body absorb the medicine properly so it can work effectively. The 2.5mg and 10mg doses can be taken with or without food.

Alcool

Drinking alcohol while taking these medicines can increase the risk of bleeding in your stomach and intestines. It is best to keep your alcohol intake within the recommended low-risk limits (no more than 14 units per week).
