Coenzyme q10 generally has no effect on liver function. Coenzyme q10 is a fat-soluble vitamin drug that can participate in the metabolism of biological cells, respiration and other functions, as well as certain antioxidant and immunity-enhancing effects. It can be used as an adjunctive treatment for coronary heart disease, heart failure, viral hepatitis, arrhythmia, hypertension and other diseases. The adverse reactions of coenzyme q10 are relatively few, and may lead to gastrointestinal reactions such as loss of appetite, nausea, diarrhea, gastric distension, etc. A small number of patients may also cause palpitations, allergies and other side effects, but generally do not lead to liver function damage. Allergic patients are not recommended to take; also not recommended to take with hypoglycemic drugs, lipid regulating drugs and other drugs at the same time. It also needs to be stored away from light because it decomposes easily in the presence of light. Although coenzyme q10 can be used for the treatment of many diseases, it is difficult to achieve the therapeutic effect of a single drug. Therefore, it is necessary to identify the cause of the problem after regular consultation, and cooperate with other drugs under the guidance of the doctor for treatment.
