Safety and side effects
CoQ10 supplements appear to be safe and to produce few side effects when taken as directed.
Mild side effects might include:
- Upper abdominal pain
- Loss of appetite
- Light sensitivity
The safety of use of CoQ10 during pregnancy and breast-feeding hasn't been established. Don't use CoQ10 if you're pregnant or breast-feeding.
Possible interactions include:
Anticoagulants. CoQ10 might make blood-thinning drugs, such as warfarin (Coumadin, Jantoven), less effective. This could increase the risk of a blood clot.
