Birth defects and isotretinoin -
Skip navigation. Isotretinoin is a molecule and a byproduct metabolite of vitamin A, and in greater than normal amounts in pregnant women, it can cause fetal abnormalities including cleft lips, ear and eye defects, and mental retardation.
Isotretinoin is commonly called by its trade name Accutane, and it's a chemical compound derived from vitamin A, also called retinoic acid. Doctors prescribe isotretinoin to treat severe acne. For pregnant women, too much vitamin A or isotretinoin can also cause greater than normal rates of stillbirths and fetal disintegrations after the ninth week of gestation. Women who use isotretinoin during the first trimester of their pregnancies, even in small amounts, risk defects to their fetuses such as external ear malformations, cleft palates, undersized jaws micrognathiaa variety of heart defects, buildups of fluids inside the skulls that leads to brain swelling hydrocephalussmall heads and brains microcephalyand mental retardation.
Derivatives of vitamin A, called retinoids, function in proper embryonic development. With insufficient vitamin A, embryos fail to segment and grow, blood vessels fail to form, and the embryo is ultimately lost. Retinoids are involved in the expression of Hox geneswhich function in signaling pathways that regulate the patterning of embryonic structures during the fourth week of development.
However, embryos exposed to excess vitamin A have higher than normal amounts of retinoids, and their Hox genes malfunction, disrupting genetic control of body shape axial patterning during the embryo's development. Such disruptions can lead to developmental defects, particularly in the embryonic spinal cord, central nervous systemand spinal cord, where retinoic acid synthesizes and where catabolic enzymes are located.
Researchers have studied the ability of large doses of vitamin A to cause birth defectsor teratogenicity, since the s. In Sidney Q. Cohlan, a researcher at the Beth Israel Hospital in New York City, New York, published research reporting the effects of excessive maternal vitamin A intake on newborn rats.
Werner Bollag initially studied isotretinoin for the treatment of skin cancer at the Department of Experimental Medicine, Hoffman-La Roche laboratories in Basel, Switzerland, in the s. InBollag discovered the compound's ability to treat acne, but with isotretinoin's lack of effect in cancer treatments, Bollag abandoned it as a pharmaceutical.
In the Gary Peck and Frank Yoder in the US rediscovered isotretinoin's therapeutic effects for the treatment of cystic acne, a severe form of acne that causes inflammation deep below the skin's surface. The FDA recognized isotretinoin as teratogen before it was first marketed inand classified isotretinoin as a Category X drug.
Category X, considered the most severe on the FDA's list of assigned pregnancy categories, includes drugs for which studies in animals or humans have displayed fetal abnormalities and that the use of the drug by pregnant women clearly outweighs any potential benefits.
In June doctors in New Jersey reported to the FDA the first incidence of human teratogenicity, or agent-caused developmental birth defectslinked to Accutane. The drug had been on the market for acne treatment for nine months. That same month, two additional cases were reported to the FDA. In response, Hoffman-La Roche distributed red warning stickers to pharmacies for Accutane containers and revised Accutane's drug label to include more information about the possibility of birth defects.
The label was revised a second time in September when Public Citizen, an advocacy organization in Washington, D. Doctors prescribed Accutane topatients within its first eighteen months of marketing, and by earlyHoffman-La Roche received reports of twenty Accutane-affected infants. On 11 Februarybased on an estimate that anywhere from to 1, infants had been affected by Accutane in the US, several members of the committee urged that Accutane be removed from the market.
The FDA, however, acknowledged only sixty-two reports of affected babies. All four babies were born with severe birth defects. At the FDA's Dermatologic Drugs Advisory Committee meeting insome argued that Accutane should remain available as an acne treatment due to its exceptional efficacy and short treatment duration of fifteen to twenty weeks. The committee voted four-to-three to allow Accutane to remain on the market with restricted access. A month later, the FDA announced that it would not follow the committee's recommendation to restrict the drug and instead issued new label warnings.
The PPP informed patients about the risks and benefits associated with isotretinoin, assisted physicians in complying with the package insert requirements, and evaluated a patient's ability to adhere to the requirement of not being or becoming pregnant one month before, during the course of, or one month after therapy.
The PPP protocol required that women use two forms of effective contraceptive during therapy, follow-up with officials through phone calls and questionnaires, and that they be offered reimbursement for contraceptive counseling and pregnancy testing.
Throughout the s, Hoffman-La Roche struggled with the consequences of Accutane's teratogenicity, and the company became involved in several court cases in Ohio and New Jersey about Accutane's teratogenicity. Of these cases, a number involved documents that allegedly indicated Hoffman-La Roche's negligence.
In one case, Hoffman-La Roche sued Frank Yoder, the co-discoverer of Accutane's therapeutic effects, for his attempt to threaten the company into purchasing his private collection of documents, which according to Yoder, dealt with "the development, use, and misuse of isotretinoin Accutane.
After the case was settled, Hoffman-La Roche requested that the documents obtained by the Hammocks during discovery be sealed. Public Citizen challenged the court's decision to seal the documents.
Eventually, the New Jersey Supreme Court concluded that based on the policy of public access to information about health, safety, and welfare, the documents should be released. On 9 Maythe documents were officially unsealed.
The documents, however, did not provide the conclusive evidence that Public Citizen had expected; records showed that within a year of releasing the drug to the market, the company became anxious about Accutane and its related birth defectsand that the first documented Accutane baby was born on 29 April Although Yoder and Public Citizen failed to provide evidence that Hoffman-La Roche indeed withheld information from the FDA and researchers in the US, the three aforementioned cases prompted some to question Hoffman-La Roche's behavior, including the company's initial proposal to give Accutane a pregnancy risk rating of category C, meaning that the drug adversely affects fetuses, but that the benefits of the drug outweigh the risks for humans.
US patients using Accutane must enroll in this risk management program designed to prevent fetal exposure to isotretinoin. Physicians and pharmacies must enroll in the program before they may prescribe or dispense isotretinoin. For a woman to receive isotretinoin, iPLEDGE requires that she must use two forms of contraceptionsubmit a negative pregnancy test to her physician each month over the course of her therapy, answer questions about iPLEDGE each month before receiving her prescription via the online iPLEDGE system, and pick up her prescription within a seven-day window.
During the first year of the program, women on isotretinoin became pregnant, about the same number of pregnancies as the year prior.
However, much fewer patients were treated with isotretinoin. Since its release, Accutane has been prescribed to approximately five million people nationwide and twelve million worldwide, with eighty-five percent of all treated patients achieving complete elimination of acne after a course of therapy. Although the risks associated with isotretinoin remain, and fetal exposure to the drug has not been completely eliminated.

It makes white blood cells to protect the body from infection. Problems with the parathyroid glands. These glands make parathyroid hormone, which helps keep the right balance of calcium in the body. How can you prevent birth defects caused by isotretinoin?
If you take birth control pills, tell your provider what you take. Some may not work if you take them with isotretinoin, so you may need to switch to a different pill. For example, progestin-only birth control pills also called mini-pills may not work with isotretinoin. Progestin is a female hormone. Tell your provider. You can work together to manage your treatment to stop taking the medicine before you get pregnant.
Your provider can help you choose two effective forms of birth control that work well together. The most effective forms of birth control are implants and intrauterine devices also called IUDs. Your provider places these in your body, and they help prevent pregnancy for a long time. Talk to your provider about what kinds of birth control to use. To take regular pregnancy tests before, during and after treatment. You need a prescription an order from your provider to get these medicines.
If a pregnant woman gets your donated blood, there may be enough medicine in it to cause birth defects in her baby. The uterus is the place inside you where your baby grows during pregnancy.

You have a late or missed menstrual period. You have sex without using two forms of effective birth control. Can oral retinoids other than isotretinoin cause birth defects? This medicine treats severe psoriasis, a skin disease that causes itchy or sore patches of red skin with thick, silvery scales. In that study , they found that a large proportion of patients taking isotretinoin experienced mental health issues, including anxiety, depression, eating disorders, and sometimes suicide.
Massachusetts General Hospital researchers have identified markers that can distinguish between major subtypes of lung cancer and accurately identify lung cancer stage. Their work could eventually help physicians decide whether patients need standard treatment or more aggressive therapy.

The approach suggested by these guidelines cannot be expected to prevent all fetal exposures. It can be anticipated that infants will be born with defects caused by first-trimester exposures to the synthetic retinoids isotretinoin and etretinate as long as these drugs are available for use.

Date July 17, Isotretinoin also known by its former brand names Accutane or Roaccutane is an extremely effective acne medication that can help patients whose severe acne has not responded to other drugs. But the drug is also a potent teratogen — if a woman takes isotretinoin while pregnant, even for a short time, her fetus runs a high risk of severe birth defects.
Inthe U. Federal Drug Administration imposed a special restricted distribution program, known as iPLEDGEthat has stringent, recurring requirements for patients, prescribing physicians, and dispensing pharmacists.
Despite the substantial imposition of iPLEDGE on patients and clinicians, the extent to which it has reduced pregnancy and other adverse effects had been unknown. In a paper published in JAMA Dermatology, the team reports that although the number of pregnancies among women taking isotretinoin has decreased, incidences of pregnancy persisted even after iPLEDGE was implemented.
They must repeat a pregnancy test and attestation every month they continue taking the drug. Each month, physicians prescribing the drug must enter the test results and the pharmacist must obtain authorization from the iPLEDGE program.
In the current study, investigators analyzed FDA reports of pregnancy-related adverse events associated with isotretinoin from Jan. Reported pregnancies peaked in before settling into a range of to per year after The authors note that several factors beyond iPLEDGE may be contributing to the downward trend, including a national decrease in teen pregnancies and increased use of long-term birth control and emergency contraception.
Earlier this month, Mostaghimi and colleagues used the FAERS database to look at a different constellation of side effects: those related to mental health. In that studythey found that a large proportion of patients taking isotretinoin experienced mental health issues, including anxiety, depression, eating disorders, and sometimes suicide.
