Traitement et médicaments
Can I take Clarithromycin and Rosuvastatin together?
Taking these two medicines together can significantly increase the amount of rosuvastatin in your blood. This increases the risk of serious muscle damage (rhabdomyolysis), which can lead to kidney problems. Symptoms to watch for include unexplained muscle pain, tenderness, or weakness, especially if you also feel generally unwell or have a fever.
