Axiron and Breastfeeding
Women are generally advised to avoid Axiron (testosterone topical solution), especially while breastfeeding. The testosterone in this product has the potential to decrease the supply of breast milk, increase the risk of postpartum blood clots, and cause other problems. Your partner can still use Axiron, as long as you both take precautions to minimize any contact you may have with the solution.
Axiron® (testosterone topical solution) is a prescription medication approved for use only in men, as it contains testosterone. The manufacturer warns that breastfeeding women should not use Axiron under any circumstances. Women who are breastfeeding should not intentionally use this medication and should be very careful to prevent unintentional exposure to it.
It is not known if testosterone (the active ingredient in Axiron) passes through breast milk in large amounts or if it could cause problems in nursing infants. There might be particular concern for female infants.
Also, testosterone was once used to suppress lactation in women who chose not to breastfeed. It seems that testosterone inhibits prolactin, a hormone important for breastfeeding. Because Axiron has the potential to decrease your breast milk supply and may increase the risks of postpartum blood clots, you should not take Axiron while breastfeeding.
As long as you both take appropriate measures, it is fine for your partner to use Axiron while you are breastfeeding. It's important to know that you can be exposed to the drug through skin-to-skin contact with the area the product was applied, even hours later.
Your partner should keep the application area covered with clothes in order to minimize contact. Axiron dries on the skin and slowly releases testosterone into the bloodstream all day long until it is washed off. If you think you have been exposed to Axiron, wash the affected area immediately and thoroughly.
