Hi, Thank you and pleased to answer you Atorvastatin belongs to the group of drugs known as HMG-CoA reductase inhibitors ( statins ) or regulators of lipid metabolism. This medication is used to treat people who have high cholesterol, including people who have some genetic origin cholesterol disorders. Atorvastatin is also used to reduce the risk of heart attack in people who experience symptoms associated with heart disease. Atorvastatin is also useful in reducing the risk of heart attack in people with high blood pressure and at least 3 other risk factors for heart disease, but who do not observe symptoms associated with heart disease. Many medications can cause side effects. A side effect is an adverse response to a drug when taken at normal doses. It can be mild or severe, temporary or permanent. The profile of adverse effects of statins (atorvastatin, simvastatin, pravastatin, etc.) consists mainly of frequent digestive disorders of headache, dizziness, insomnia, visions disorders, dysgeusias. The symptoms you describe are dependent on your statin use that you need to stop. You can do more sports and more diet without animal proteins in order to regulate your cholesterol levels. If the diet and exercise can’t stabilize your cholesterol level, you can use the least dosage of atorvastatin (10 mg ONCE DAILY) with drug covering stomach complaints like Nexium 20 once daily (Proton pump inhibitors). THERE ARE NO INTERACTIONS BETWEEN ATORVASTATIN AND NEXIUM. BEST WISHES.
