Don’t stop atorvastatin on your own
Atorvastatin is used to lower cholesterol and reduce cardiovascular risk. If you develop troublesome symptoms, your clinician can determine whether atorvastatin is responsible and whether a dose adjustment, different statin, or alternative treatment is appropriate. nhs.uk
