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.
What you should do
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.

Can I take Hydroxycarbamide and Hydroxychloroquine together?
