Statins can cause muscle cramps
People taking statins to lower their cholesterol may sometimes experience muscle cramps. In fact, muscle pain and muscle cramps are the two most commonly reported side effects of statins, although they usually only happen in the first few weeks of taking the medication. Doctors often advise against strenuous workouts or exercises that work the muscles too much when starting treatment with statins. For most people, these side effects will disappear over time. This is because statins block the production of so-called “bad” cholesterol in the blood. However, the drug also affects cholesterol levels in other cells as well. In the case of muscle cells, reduced cholesterol can impact muscle growth and function. This may be the reason statins causes muscle cramp.
