Can I take Aspirin and Metformin together?

Why this happens

Aspirin can make the body more sensitive to insulin and may slightly increase the amount of insulin released. When combined with metformin, this can occasionally lead to a stronger blood-sugar-lowering effect than intended.

You can usually take these medicines together, but you should monitor your blood sugar levels more closely, especially when starting or changing the dose of aspirin. Learn to recognise signs of low blood sugar, such as feeling shaky, sweaty, hungry, or dizzy. If you notice these symptoms frequently, speak to your doctor.

Asthme

Do not take aspirin if you have a history of asthma triggered by aspirin or other non-steroidal anti-inflammatory drugs (NSAIDs), as it can cause a life-threatening asthma attack.

Severe kidney disease

You must not take metformin if your kidneys are not working properly. This can lead to a rare but life-threatening build-up of lactic acid in the blood (lactic acidosis).

Children under 16 years old

Never give aspirin to children under 16 unless specifically prescribed by a doctor. It can cause Reye’s syndrome, a rare but potentially fatal condition affecting the brain and liver.

Alcool

Drinking alcohol while taking aspirin can increase the risk of stomach irritation and bleeding. It is best to limit alcohol intake, especially if you take aspirin regularly.
