Should You Stop Atorvastatin?
Don’t stop it on your own. Stopping a statin can allow cholesterol to rise again and remove some of its protection against cardiovascular disease. If you think you’re experiencing side effects, a doctor or pharmacist can review your dose, other medicines, and possible alternatives. nhs.uk+1
Also tell your healthcare professional about all medicines and supplements you take. Certain antibiotics, antifungals, cardiovascular medicines, and grapefruit can increase the risk of atorvastatin side effects. nhs.uk
