This sheet talks about exposure to isotretinoin in a pregnancy or while breastfeeding. This information should not take the place of medical care and advice from your healthcare provider.
What is isotretinoin?
Isotretinoin is a prescription medication taken by mouth to treat severe cystic acne that has not responded to other treatments. Isotretinoin is a form of Vitamin A. It has been sold under brand names such as Accutane®, Absorica®, Amnesteem®, Claravis®, Epuris®, Clarus®, Myorisan®, Sotret®, and Zenatane®.
How long after a woman stops taking isotretinoin should she wait to become pregnant? How long does isotretinoin stay in the body?
It is recommended that a woman wait one month after stopping isotretinoin before trying to become pregnant. Usually, isotretinoin is no longer found in a woman’s blood 4-5 days after the last dose and most of its by-products should be gone within 10 days after the last dose. However, the time it takes isotretinoin to be cleared from the body can be longer in some people, which is why it is recommended to wait at least one month after stopping isotretinoin before trying to become pregnant.
Can isotretinoin make it more difficult to get pregnant?
Women who are trying to become pregnant should not be taking isotretinoin. There have been reports of irregular menstrual periods in some women taking isotretinoin. There are no reports of problems getting pregnant while taking isotretinoin.
I just found out I am pregnant. Should I stop taking isotretinoin?
Stop taking the medication right away. As soon as possible, call the healthcare provider who prescribed the isotretinoin and the healthcare provider who will be taking care of you during your pregnancy. Your healthcare team can talk with you about screening tests and ultrasounds. Ultrasound can detect many (but not all) birth defects. Ultrasound cannot tell if a child may have learning or developmental problems.*
Does taking isotretinoin cause an increased risk for miscarriage or infant death?
Miscarriage can occur in any pregnancy. However, the chance for having a miscarriage can be as high as 40% when a woman takes isotretinoin in early pregnancy.*
Can taking isotretinoin during pregnancy cause birth defects?
In every pregnancy, a woman starts out with a 3-5% chance of having a baby with a birth defect. This is called her background risk. Isotretinoin causes birth defects in more than 35% of infants whose mothers take the drug during pregnancy. The chance of having a baby with a birth defect applies even if the medication has been taken for a short time. Most of the infants with birth defects will have small or absent ears, hearing and eyesight problems. Life-threatening heart defects and fluid around the brain are other birth defects that have be seen in some infants. Some will have a small jaw, small head, cleft palate and some will be born with a small or missing thymus gland (a gland in our body that makes hormones).*
Will taking isotretinoin have an effect on a baby’s behavior and development?
Many of the exposed children will have moderate to severe behavioral problems and/or intellectual disability. These difficulties do not get noticed at birth, but are discovered in childhood. Other possible long-term effects on any exposed child are still unknown.*
Can a woman still get a prescription for isotretinoin?
Isotretinoin can be prescribed under a special program called iPLEDGETM. Women MUST adhere to all requirements of the iPLEDGE program. Following are some of the requirements:*
- Women must be able to understand that severe birth defects can occur with use of isotretinoin.
- Women must receive and be able to understand safety information about isotretinoin and the iPLEDGE requirements.
- Women must sign an Informed Consent Form that contains warnings about the risks of using isotretinoin.
- Women must not be pregnant or be breastfeeding.
- Women must have two (2) negative pregnancy tests before starting isotretinoin.
- Women must have a pregnancy test every month during treatment, and a negative test a month after treatment.
- Women must use two (2) different forms of birth control at all times (unless woman agrees not to have sex) starting one (1) month before treatment continuing during treatment, and for one (1) month after treatment.
- Women must fill their prescription within 7 days after the health care provider visit.
- Women must agree to see their health care provider every month during treatment for a health check and to get a new prescription.

MotherToBaby recommends that women who are not sexually active still talk to their health care provider about using safe and effective birth control methods because almost 50% of all pregnancies are unplanned or unintended.
Can I use isotretinoin while breastfeeding my baby?
There have been no studies looking at taking isotretinoin during breastfeeding. It is not known if isotretinoin can get into breast milk but other similar medications can. We do not know what effect exposure to isotretinoin through the breast milk can have on a nursing infant. Until more is known, women who are breastfeeding should not take isotretinoin. Be sure to talk to your health care provider about all your breastfeeding questions.
What about topical tretinoin?
Topical tretinoin (Retin-A® and other brand names) is used as a cream or a gel on the skin to treat acne and other skin problems. Tretinoin is related to Vitamin A and isotretinoin. For information on topical tretinoin, please see the MotherToBaby fact sheet Tretinoin (Retin-A®) at https://mothertobaby.org/fact-sheets/tretinoin-retin-a-pregnancy/pdf/.
What if the father of the baby takes isotretinoin?
Isotretinoin does not appear to affect sperm. There have been a few reports of erectile dysfunction and ejaculatory failure in men taking isotretinoin, but there have been no reports of isotretinoin causing infertility in men. There are no studies looking at risks for birth defects when the father takes isotretinoin. In general, exposures that fathers have are unlikely to increase risks to a pregnancy.
