Interaction Details
There were no interactions found between Evolocumab 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!

Evolocumab Overview
-
Evolocumab injection is used to reduce the risk of a stroke or heart attack or the need for coronary artery bypass (CABG) surgery in people with cardiovascular disease. Evolocumab injection is also used along with diet alone or in combination with other cholesterol-lowering medications such as HMG-CoA reductase inhibitors (statins) or ezetimbe (Zetia) to decrease the amount of low-density lipoprotein (LDL) cholesterol ('bad cholesterol') in the blood, including people who have familial heterozygous hypercholesterolemia (HeFH; an inherited condition in which cholesterol cannot be removed from the body normally). It is also used along with diet changes and other treatments to reduce the amount low-density lipoprotein (LDL) cholesterol ('bad cholesterol')in the blood in people that have homozygous familial hypercholesterolemia (HoFH; an inherited condition in which cholesterol cannot be removed from the body normally). Evolocumab injection is in a class of medications called proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitor monoclonal antibody. It works by blocking the production of LDL cholesterol in the body to decrease the amount of cholesterol that may build up on the walls of the arteries and block blood flow to the heart, brain, and other parts of the body.
-
Accumulation of cholesterol along the walls of your arteries (a process known as atherosclerosis) decreases blood flow and, therefore, the oxygen supply to your heart, brain, and other parts of your body.
