Puis-je prendre de la Warfarine et de l'Ibuprofène ensemble ?

Pourquoi cela se produit

This is a 'double whammy' effect. Warfarin works by slowing down the blood's ability to clot. Ibuprofen also thins the blood by affecting platelets, and it can irritate the lining of the stomach, making ulcers or bleeding more likely. Together, they make it much harder for your body to stop any bleeding that starts.

You should avoid taking ibuprofen (or other similar anti-inflammatories like aspirin or naproxen) while taking warfarin unless specifically told to do so by your doctor. For pain relief, paracetamol is usually a much safer choice. If you have already taken them together and notice signs of bleeding—such as dark, tarry stools, bruising easily, or a nosebleed that won't stop—seek medical advice immediately.

Combined use (Drug-Drug Interaction)

Do not take ibuprofen while taking warfarin. Ibuprofen significantly increases the risk of severe internal bleeding and can interfere with how warfarin works. Use paracetamol for pain relief instead.

Asthme

Do not take ibuprofen if you have asthma, as it can trigger a life-threatening asthma attack or worsening of breathing difficulties in some people.

Grossesse

Warfarin must not be taken during pregnancy as it can cause serious birth defects and fatal bleeding in the unborn baby. Use effective contraception while taking this medicine.

Grossesse (troisième trimestre)

Ne prenez pas d'ibuprofène si vous êtes enceinte de plus de 6 mois, car cela peut provoquer de graves problèmes cardiaques et rénaux chez le bébé à naître ainsi que des complications lors de l'accouchement.

Alcool

Avoid binge drinking. Regular, moderate consumption is usually fine, but sudden changes in alcohol intake can affect how warfarin works and increase the risk of bleeding.

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.

Foods high in vitamin K (e.g. spinach, kale, broccoli, Brussels sprouts)

You do not need to avoid these, but you must keep your intake consistent. Vitamin K helps blood clot, which works against warfarin. A sudden increase or decrease in these foods can change your INR levels.

Jus de canneberge et produits à base de canneberge

Avoid or limit cranberry juice. It can increase the effect of warfarin, making you more likely to bleed.

Jus de pamplemousse

It is best to avoid large amounts of grapefruit juice as it may increase the risk of bleeding, though the evidence is less consistent than with other foods.

Jus de grenade

Avoid or limit pomegranate juice as it may increase the effect of warfarin and the risk of bleeding.

Nourriture (Général)

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