Can I take Metformin and Naproxen together?

Why this happens

Naproxen is a non-steroidal anti-inflammatory drug (NSAID) that can reduce blood flow to the kidneys and affect how well they filter waste. Since metformin is removed from the body by the kidneys, any decrease in kidney function can cause metformin levels to rise, increasing the risk of side effects.

What you should do

Use this combination with caution. If you need to take naproxen, keep it to the lowest dose for the shortest time possible. Ensure you stay well-hydrated. Speak to your doctor if you have any existing kidney problems, or if you experience unusual muscle pain, trouble breathing, or feeling very weak and cold.
