Can I take Warfarin and Paracetamol together?

Por qué sucede esto

Warfarin works by blocking the body's ability to use Vitamin K to clot blood. Paracetamol (specifically a breakdown product of it) can interfere with the same enzymes warfarin targets, which adds to the blood-thinning effect.

If you only need a one-off dose of paracetamol, it is generally safe. However, if you need to take paracetamol regularly (for more than 3 or 4 days), you must inform your doctor or anticoagulant clinic. They may need to monitor your INR (blood clotting speed) more frequently and adjust your warfarin dose. Always report any unusual bruising, nosebleeds, or bleeding gums to your healthcare provider.

Riesgo de sangrado

Warfarin increases your risk of serious bleeding. You must seek immediate medical attention if you have a fall, a head injury, or notice signs of internal bleeding such as dark/tarry stools or coughing up blood.

Interacción de medicamentos

Taking paracetamol regularly or in high doses while on warfarin can increase your risk of bleeding. Consult your doctor before taking paracetamol for more than a few days.

Daño hepático

Never exceed the maximum dose of paracetamol (usually 4g in 24 hours). Taking too much can cause fatal liver damage, and symptoms may not appear for several days. Check all other medicines (such as cold and flu remedies) to ensure they do not also contain paracetamol.

Embarazo

La warfarina puede causar daños graves a un bebé no nacido. Debe usar anticonceptivos efectivos mientras la toma y informar a su médico de inmediato si piensa que está embarazada.

Alcohol

t is best to avoid or strictly limit alcohol when taking paracetamol. Combining alcohol and paracetamol increases the risk of serious liver damage.

It is best to avoid or strictly limit alcohol while taking warfarin. Alcohol can affect how your liver processes the medicine, which may increase your risk of bleeding or cause your INR levels to become unstable. If you do drink, keep it to a minimum and do not binge drink.

Alimentos ricos en vitamina K (por ejemplo, espinacas, col rizada, brócoli, coles de Bruselas, espárragos)

La vitamina K ayuda a que la sangre coagule, lo cual contrarresta el efecto de la warfarina. No es necesario evitar completamente estos alimentos, pero debes mantener la cantidad que consumes de manera constante. Un aumento o disminución repentina en la ingesta de vitamina K puede alterar la efectividad de tu warfarina.

Cranberry juice and Goji berries

Cranberry juice and goji berry products can significantly increase the blood-thinning effect of warfarin, leading to a higher risk of bruising or bleeding. It is best to avoid these while taking warfarin.

Jugo de toronja

El jugo de pomelo puede aumentar los niveles de warfarina en su sangre, lo que puede incrementar su riesgo de sangrado. Es mejor evitar el jugo de pomelo.

Jugo de granada

Algunas evidencias sugieren que el jugo de granada puede interactuar con la warfarina y aumentar el riesgo de sangrado. Es mejor evitarlo.
