Interaction Details
There were no interactions found between Denosumab and Coenzyme Q10. This does not mean the potential for an interaction does not exist, however. There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
Pharmacist Analysis
Although CoQ10 is considered relatively safe for most individuals, it does have some reported interactions that are important to be aware of.
This includes:
- Antihypertensives: Clinical research has shown that CoQ10 can significantly lower blood pressure but conflicting results have been reported.
- Warfarin: Research is conflicting but concomitant use of CoQ10 and warfarin might reduce the anticoagulant effects of warfarin.
- Alkylating Agents: Antioxidants such as CoQ10 might also protect tumor cells from chemotherapeutic agents that work by inducing oxidative stress, such as alkylating agents (e.g., cyclophosphamide) and radiation therapy.
Outside of the interactions I've listed above, CoQ10 is generally considered safe to supplement with in most situations.
In fact, some individuals taking certain medications (e.g., 'Statins') may be recommended to take it.
If you have any questions about CoQ10 supplements, be sure to speak to your healthcare professional. We are always happy to answer questions on the matter as well!
