Taking fenofibrate and naproxen together may increase the risk of kidney problems. Both medications can put strain on the kidneys, and using them at the same time can make it harder for your kidneys to filter waste from your blood. In rare cases, this can also lead to a serious muscle condition called rhabdomyolysis, where muscle tissue breaks down and releases substances into the blood that can damage the kidneys further.

Why this happens
Fenofibrate and naproxen (an NSAID) are both processed and cleared by the kidneys. Naproxen can reduce blood flow to the kidneys by blocking certain protective chemicals (prostaglandins). When kidney function is slowed down by naproxen, fenofibrate levels can build up in the body, increasing the risk of muscle toxicity and further kidney strain.
What you should do
Use this combination with caution. If you need to take naproxen for a short time, ensure you stay well-hydrated. If you have pre-existing kidney issues, speak to your doctor before taking naproxen, as they may suggest an alternative like paracetamol. Seek medical advice immediately if you experience unexplained muscle pain, tenderness, weakness, or if your urine becomes very dark in colour.
