Statins can be taken on a long-term basis as prescribed by the doctor if they meet the drug indications. 1. Statins are mainly used to lower blood lipids. For patients with high blood lipids and atherosclerosis, statins can lower total cholesterol and LDL cholesterol. Common statin drugs include simvastatin, atorvastatin, pravastatin, fluvastatin, resuvastatin and so on. 2. Adverse effects of statin drugs include gastrointestinal reactions, headache, skin flushing, myalgia, rhabdomyolysis, etc. 3. Active liver disease, patients with unexplained transaminase elevation are prohibited, pregnant and lactating women are prohibited. 4. Since the drugs are mostly metabolized in the liver, kidney and other organs, so if patients take statins for a long time, then it is recommended that they check their liver function regularly or observe whether they have symptoms such as loss of appetite and yellowing of the skin. If there are muscle aches and pains and other conditions arise, it is also necessary to go to the hospital to check creatine kinase and other relevant indicators. Note that statins are prescription drugs and need to be used under the guidance of a doctor to avoid taking them without authorization.
