Coenzyme Q10 and breastfeeding
From LactMed, the US National Library of Medicine’s Drugs and Lactation Database — quoted, not rewritten.
Full LactMed record for coenzyme q10: levels in milk, effects in breastfed infants, and the drugs it would consider insteadCoenzyme Q10 (ubiquinone) is a normal part of the diet, and is also endogenously synthesized. It is a normal component of human milk, but milk levels are slightly low in the breastmilk of mothers with preterm infants. Coenzyme Q10 has no specific lactation-related uses and no data exist on the safety and efficacy of supplementation in nursing mothers or infants. Coenzyme Q10 supplements are usually well tolerated with only infrequent, minor side effects.

What people report to the FDA about coenzyme q10
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 23,706 reports naming coenzyme q10, and the FDA flagged 54% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- fatigue2,613 reports
- diarrhoea1,785 reports
- nausea1,570 reports
- headache1,563 reports
- dizziness1,345 reports
- asthenia1,271 reports
- dyspnoea1,228 reports
- arthralgia1,163 reports
Read these as a signal, not a rate. A report does not mean coenzyme q10 caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label section above.

Frequently asked questions
What is Coq10?
Antioxidant supporting cellular energy and heart health, popular with statin users.
Can you take coenzyme q10 with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run coenzyme q10 against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
Is there a generic coenzyme q10?
We do not currently list a generic-labelled coenzyme q10 product. That does not always mean none exists — it means none appears under a generic name in the FDA data we track. Ask your pharmacist.
