Coenzyme Q10 mainly has the effects of enhancing immunity, protecting the heart muscle, increasing cardiac output and reducing peripheral resistance, and is used for the adjuvant treatment of diseases, such as heart disease, viral myocarditis, chronic cardiac insufficiency, and also for the adjuvant treatment of hepatitis, and can also reduce the side effects caused by cancer radiotherapy and chemotherapy. Coenzyme Q10 is more effective when taken 3 times/day, 10mg/dose, 30 minutes after meals. Side effects such as digestive discomfort, loss of appetite, nausea, diarrhea, palpitations and other side effects may occur after using the drug, but they are relatively mild and can be relieved after stopping the drug. There is insufficient experience in the application to women during pregnancy and lactation, so use with caution.
