Hypotension is not a contraindication to coenzyme Q10, so patients with hypotension can take coenzyme Q10. Coenzyme Q10 is a fat-soluble quinone compound, which can promote oxidative phosphorylation reaction, increase the supply of ATP to the body cells, thus protecting the biofilm from being destroyed, and can play a role in nourishing the myocardium and improving myocardial metabolism. Clinically, it is usually used in the adjuvant treatment of cardiovascular diseases (such as viral myocarditis, chronic heart failure, etc.). Adverse reactions to Coenzyme Q10 are rare, commonly include dyspepsia, nausea, vomiting, lack of appetite and diarrhea, etc. Usually the reactions are mild, occasionally allergic reactions as well as transient palpitations (accelerated heartbeat, often accompanied by panic) can occur. Coenzyme Q10 is contraindicated in people who are allergic to the components of the drug, and should be used with caution in patients with bile duct obstruction, oral hypoglycemic drugs, and renal insufficiency. Although Coenzyme Q10 is a relatively safe drug, it is still necessary to follow the advice of specialists in the use of drugs to avoid drug abuse, in the period of taking the drug if there is an adverse reaction, should be timely to the hospital.
