AIDS Home > Prezista and Breastfeeding
No studies have been conducted on Prezista and breastfeeding, so it is unknown whether the drug passes through breast milk in humans. Since women with HIV or AIDS are generally recommended to avoid breastfeeding (HIV can be transmitted through breast milk), most women taking Prezista should also avoid breastfeeding. Talk to your healthcare provider about Prezista and breastfeeding to discuss the possible risks.
Currently, it is not known whether Prezista™ (darunavir ethanolate) passes through breast milk in women. More importantly, breastfeeding is not recommended for women with HIV or AIDS in developed countries (such as the United States), in order to reduce the chance of transmitting the HIV infection to their infants. Therefore, most women taking Prezista should avoid breastfeeding.
Studies have shown that Prezista passes through breast milk in rats, but no studies have been conducted on whether the drug passes through breast milk in women. The HIV virus can also pass through breast milk, so any HIV-infected woman who can safely feed her baby formula should not breastfeed. There are some situations in which formula feeding is not safe, such as if no clean water supply is available to mix the formula or to wash the bottles. In these situations, it is difficult to know whether breastfeeding or formula feeding is more dangerous. In general, using both breastfeeding and formula feeding is considered the most dangerous, as digestive system irritation or infections from unclean water can allow HIV to pass into the body from the digestive tract more easily.
You should talk with your healthcare provider about Prezista and breastfeeding. Each woman's situation is different, and you and your healthcare provider understand your situation best. After considering what you want and expect, as well as your current health situation, the two of you can make a shared decision about Prezista and breastfeeding that is right for you.
