It is unknown whether Aldara (imiquimod cream) passes through human breast milk. However, based on the chemical properties of the drug, it is expected that some of it would pass through breast milk. Because of the unknown risks, the manufacturer recommends that breastfeeding women use Aldara with caution.
Can Breastfeeding Women Use Aldara?
At this time, it is not clear if Aldara® (imiquimod cream) is safe for use in women who are breastfeeding. The manufacturer of Aldara recommends that women use the medication with caution while nursing. Therefore, if you are breastfeeding or plan to start, you should talk with your healthcare provider before using this medicated skin cream.
More Information on Aldara and Breastfeeding
No research has been done to determine whether imiquimod (the active ingredient in Aldara) passes through breast milk in humans. However, based on the chemical properties of the drug, it probably does pass through breast milk to some extent.
However, due to the low overall exposure of the body to imiquimod with Aldara (since only a small amount of the medication is used and an even smaller amount is absorbed through the skin), it is not expected that Aldara would cause serious problems.
Nonetheless, the remote possibility that Aldara could cause problems in a nursing infant cannot be ruled out at this time. Keep in mind that using more of the cream than recommended significantly increases the amount of the drug absorbed (more so than would be expected), potentially exposing the baby to higher levels of the drug.
Talking With Your Healthcare Provider
You should discuss breastfeeding and Aldara use with your healthcare provider. 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 that is right for you.
