Coenzyme Q10 - Plan B (Levonorgestrel) Interaction

Interaction Details

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!

Levonorgestrel Overview

• Levonorgestrel is used to prevent pregnancy after unprotected sexual intercourse (sex without any method of birth control or with a birth control method that failed or was not used properly [e.g., a condom that slipped or broke or birth control pills that were not taken as scheduled]). Levonorgestrel should not be used to prevent pregnancy on a regular basis. This medication is to be used as an emergency contraceptive or backup in case regular birth control fails or is used incorrectly. Levonorgestrel is in a class of medications called progestins. It works by preventing the release of an egg from the ovary or preventing fertilization of the egg by sperm (male reproductive cells). It also may work by changing the lining of the uterus (womb) to prevent development of a pregnancy. Levonorgestrel may prevent pregnancy, but it will not prevent the spread of human immunodeficiency virus (HIV, the virus that causes acquired immunodeficiency syndrome [AIDS]) and other sexually transmitted diseases.
