Atorvastatin and vitamin B can generally be taken at the same time under the supervision of a physician, note that the dosage of atorvastatin should be reduced when combined with niacin. Atorvastatin is mainly used for the treatment of hypercholesterolemia and coronary heart disease or coronary heart disease crisis combined with hypercholesterolemia or mixed dyslipidemia. Vitamin B drugs are generally used for the prevention and treatment of B vitamin deficiencies. Atorvastatin, when used in combination with niacin (i.e., vitamin B3), increases the risk of skeletal muscle effects, so consideration should be given to reducing the dosage of atorvastatin when combined. Atorvastatin may also be combined with other B vitamins except niacin. Note that the drug should be contraindicated in people who are allergic to both, people with active liver disease (including unexplained elevation of aminotransferases), pregnant women, breastfeeding women and other groups. During the treatment period may occur nasopharyngitis, arthralgia, pain in the limbs, urinary tract infections, diarrhea and other common adverse reactions. Specific drugs should be used under the guidance of a specialist, and should not be used without authorization.
