Coenzyme q10 is best not taken at the same time as drugs such as cefadroxil tablets and hypoglycemia, which may interact with each other. Since coenzyme q10 is a fat-soluble antioxidant that can act as an antioxidant, usually preventing the peroxidation of proteins, scavenging free radicals and other effects, it may affect the efficacy of drugs such as cephalexin tablets. Therefore, when using drugs such as cefadroxil tablets, they should be taken separately from coenzyme q10, and can be taken more than half an hour apart. If the patient suffers from diabetes, then taking coenzyme q10 at the same time when taking drugs to lower blood sugar may inhibit the effect of coenzyme q10. It should be noted that taking coenzyme q10 at the same time may have adverse reactions such as stomach upset, loss of appetite, nausea, diarrhea, palpitations, and occasionally rash. Also prohibited for those who are allergic to this product. As a prescription drug, coenzyme q10 needs to be taken under the advice of a doctor to avoid the hazards of overdose.
