Statins, or statins, mainly have the effect of lowering blood lipids, but because they may cause some adverse reactions, the first time you take a statin usually requires a review in 4-6 weeks. Within 12 weeks of taking statins, adverse reactions such as elevated transaminases, abnormal liver function and rhabdomyolysis may occur. If patients do not experience the above conditions in the first 3 months of taking statins, the chances of adverse reactions such as elevated transaminases, abnormal liver function and rhabdomyolysis can be reduced without increasing the dose of statins thereafter, so it is recommended to review liver function, creatine kinase and blood lipids at 4-6 weeks after taking statins for the first time. If there is any abnormality, the treatment plan should be adjusted under the guidance of the doctor. In addition, high blood lipids can increase the risk of cardiovascular disease, so it is recommended that people with high blood lipids take statins as prescribed by their doctors to maintain stable blood lipid levels.
