Why this happens

Clopidogrel and metformin are processed by different pathways in the body. Clopidogrel is a blood thinner (antiplatelet) that works on blood cells, while metformin works on the liver and muscles to lower blood sugar. They do not interfere with each other's absorption, metabolism, or effectiveness.

You can safely take these two medicines together as prescribed by your doctor. Always ensure you attend your regular blood sugar checks and follow-up appointments for your heart health.
