Can I take Aspirin and Diclofenac together?

You should not take aspirina e diclofenaco together unless specifically instructed by your doctor.

Both drugs work by blocking enzymes (COX-1 and COX-2) that protect the lining of your stomach and keep your kidneys working properly.

When you take both, the protective layer in your stomach is weakened further, and blood flow to the kidneys can be reduced. Additionally, both drugs thin the blood, making any bleeding more difficult to stop.

If you must take both, your doctor may prescribe a 'stomach protector' medicine (such as omeprazol).

If you are taking aspirina de baixa dose for heart protection, speak to your GP or pharmacist before using diclofenac, as diclofenac can interfere with aspirin's heart-protective benefits and increase your risk of a stomach bleed.

How to know if you're having a drug interaction?

You may be experiencing an interaction between aspirin and diclofenac if you have:

• Stomach pain, indigestion, or heartburn.

• Náusea ou vômito.

• Black, tarry stools or blood in your stools.

• Vômito com sangue.

• Unusual bruising or bleeding.

• Dizziness or headaches.

• Swelling of the ankles or feet.

• Shortness of breath or chest pain (rare but serious).

Se você tiver algum dos sintomas acima, você deve:

• Stop taking the medicines and contact your GP or pharmacist if you develop stomach pain, indigestion, nausea, unusual bruising or mild bleeding.

• Seek urgent medical help (call 999 / go to A&E) if you have:

  • Black, tarry poo.

  • Vomit (sick) that looks like blood or coffee grounds.

  • Severe stomach pain.

  • Chest pain or shortness of breath.

  • Signs of an allergic reaction (swelling of face/lips, difficulty breathing).

Do not restart either medicine until you have spoken to a healthcare professional.

Asma

Do not take these medicines if you have asthma and have ever had a flare-up or breathing difficulties triggered by aspirin or other NSAIDs. This can cause a life-threatening allergic reaction or severe asthma attack.

Úlceras estomacais ou sangramento

Avoid these medicines if you have a history of stomach ulcers or gastrointestinal bleeding. They significantly increase the risk of serious stomach damage and internal bleeding.

Gravidez (terceiro trimestre)

Do not take these medicines if you are more than 20 weeks pregnant. They can cause serious kidney or heart problems in the unborn baby and may lead to complications during delivery.

Álcool

Drinking alcohol while taking these medicines increases the risk of irritation and bleeding in your stomach and intestines. It is best to avoid or limit alcohol consumption.

Cafeína (café, chá, bebidas energéticas)

Aspirin can increase the effects of caffeine, potentially leading to jitteriness, a racing heart, or difficulty sleeping. Additionally, both caffeine and aspirin can irritate the stomach lining, increasing the risk of indigestion or ulcers when combined.
