However, stopping the medication without medical advice can allow cholesterol levels to rise again. Higher cholesterol levels have been linked to increased risk of heart attacks and other cardiovascular conditions. Pharmacist Raj Patel recently warned about this in a TikTok video, comparing stopping the drug to giving up regular exercise.“What happens if you stop taking atorvastatin? You know when you stop exercising for a month and everything slips back?” Patel asked.“That's what happens when you stop atorvastatin. Your cholesterol creeps back up and so does your heart attack risk,” he warned.According to the UK's National Health Service (NHS), cholesterol levels may rise again after stopping atorvastatin. Patients should continue taking it unless their doctor advises otherwise.What Is Atorvastatin?Also read: Confused By Your Cholesterol Report?
