Six Contraindications for Using CoQ10
September 3, 2023
Taking CoQ10 before bed may lead to insomnia, so it's best to take it in the morning or afternoon. During pregnancy, starting CoQ10 around the 20th week is generally considered safe; however, the safety of using it while breastfeeding is still unknown, so it's advised to avoid it. Do not use CoQ10 alongside chemotherapy drugs known as alkylating agents, as it may reduce their effectiveness. This includes medications like busulfan, carboplatin, cisplatin, cyclophosphamide, dacarbazine, and thiotepa. CoQ10 may lower blood pressure, so those with low blood pressure or those taking antihypertensive medications should use it cautiously. Relevant medications include captopril, enalapril, losartan, valsartan, diltiazem, amlodipine, hydrochlorothiazide, and furosemide. Stop using CoQ10 at least two weeks before any scheduled surgery, as it may affect blood pressure control during and after the procedure. Avoid combining CoQ10 with the anticoagulant warfarin, as CoQ10 can support blood clotting and may reduce the effectiveness of the medication. If you must take both, regular blood tests are essential to monitor clotting times, especially in the first two weeks.
