For all patients:
Isotretinoin must not be taken by patients who are pregnant or who may become pregnant. There is a high risk that isotretinoin will cause loss of the pregnancy, or will cause the baby to be born too early, to die shortly after birth, or to be born with birth defects (physical problems that are present at birth).
A program called iPLEDGE has been set up to make sure that pregnant women do not take isotretinoin and that women do not become pregnant while taking isotretinoin. All patients, including women who cannot become pregnant and men, can get isotretinoin only if they are registered with iPLEDGE, have a prescription from a doctor who is registered with iPLEDGE and fill the prescription at a pharmacy that is registered with iPLEDGE. Do not buy isotretinoin over the internet.
You will receive information about the risks of taking isotretinoin and must sign an informed consent sheet stating that you understand this information before you can receive the medication. You will need to see your doctor every month during your treatment to talk about your condition and the side effects you are experiencing. At each visit, your doctor may give you a prescription for up to a 30-day supply of medication with no refills. If you are a woman who can become pregnant, you will also need to have a pregnancy test in an approved lab each month and have your prescription filled and picked up within 7 days of your pregnancy test. If you are a man or if you are a woman who cannot become pregnant, you must have this prescription filled and picked up within 30 days of your doctor visit. Your pharmacist cannot dispense your medication if you come to pick it up after the allowed time period has passed.
Tell your doctor if you do not understand everything you were told about isotretinoin and the iPLEDGE program or if you do not think you will be able to keep appointments or fill your prescription on schedule every month.
Your doctor will give you an identification number and card when you start your treatment. You will need this number to fill your prescriptions and to get information from the iPLEDGE website and phone line. Keep the card in a safe place where it will not get lost. If you do lose your card, you can ask for a replacement through the website or phone line.
Do not donate blood while you are taking isotretinoin and for 1 month after your treatment.
Do not share isotretinoin with anyone else, even someone who has the same symptoms that you have.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with isotretinoin and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website ( Web Site), the manufacturer's website, or the iPLEDGE program website ( Web Site) to obtain the Medication Guide.
Talk to your doctor about the risks of taking isotretinoin.
For female patients:
If you can become pregnant, you will need to meet certain requirements during your treatment with isotretinoin. You need to meet these requirements even if you have not started menstruating (having monthly periods) or have had a tubal ligation ('tubes tied'; surgery to prevent pregnancy). You may be excused from meeting these requirements only if you have not menstruated for 12 months in a row and your doctor says you have passed menopause (change of life) or you have had surgery to remove your uterus and/or both ovaries. If none of these are true for you, then you must meet the requirements below.
You must use two acceptable forms of birth control for 1 month before you begin to take isotretinoin, during your treatment and for 1 month after your treatment. Your doctor will tell you which forms of birth control are acceptable and will give you written information about birth control. You can also have a free visit with a doctor or family planning expert to talk about birth control that is right for you. You must use these two forms of birth control at all times unless you can promise that you will not have any sexual contact with a male for 1 month before your treatment, during your treatment, and for 1 month after your treatment.
If you choose to take isotretinoin, it is your responsibility to avoid pregnancy for 1 month before, during, and for 1 month after your treatment. You must understand that any form of birth control can fail. Therefore, it is very important to decrease the risk of accidental pregnancy by using two forms of birth control at all times. Tell your doctor if you do not understand everything you were told about birth control or you do not think that you will be able to use two forms of birth control at all times.
If you plan to use oral contraceptives (birth control pills) while taking isotretinoin, tell your doctor the name of the pill you will use. Isotretinoin interferes with the action of micro-dosed progestin ('minipill') oral contraceptives (Ovrette, Micronor, Nor-QD). Do not use this type of birth control while taking isotretinoin.
If you plan to use hormonal contraceptives (birth control pills, patches, implants, injections, rings, or intrauterine devices), be sure to tell your doctor about all the medications, vitamins, and herbal supplements you are taking. Many medications interfere with the action of hormonal contraceptives. Do not take St. John's wort if you are using any type of hormonal contraceptive.
You must have two negative pregnancy tests before you can begin to take isotretinoin. Your doctor will tell you when and where to have these tests. You will also need to be tested for pregnancy in a laboratory each month during your treatment, when you take your last dose and 30 days after you take your last dose.
You will need to contact the iPLEDGE system by phone or the internet every month to confirm the two forms of birth control you are using and to answer two questions about the iPLEDGE program. You will only be able to continue to get isotretinoin if you have done this, if you have visited your doctor to talk about how you are feeling and how you are using your birth control and if you have had a negative pregnancy test within the past 7 days.
Stop taking isotretinoin and call your doctor right away if you think you are pregnant, you miss a menstrual period, or you have sex without using two forms of birth control. If you become pregnant during your treatment or within 30 days after your treatment, your doctor will contact the iPLEDGE program, the manufacturer of isotretinoin, and the Food and Drug Administration (FDA). You will also talk with a doctor who specializes in problems during pregnancy who can help you make choices that are best for you and your baby. Information about your health and your baby's health will be used to help doctors learn more about the effects of isotretinoin on unborn babies.
For male patients:
A very small amount of isotretinoin will probably be present in your semen when you take prescribed doses of this medication. It is not known if this small amount of isotretinoin may harm the fetus if your partner is or becomes pregnant. Tell your doctor if your partner is pregnant, plans to become pregnant, or becomes pregnant during your treatment with isotretinoin.
Isotretinoin is used to treat severe recalcitrant nodular acne (a certain type of severe acne) that has not been helped by other treatments, such as antibiotics. Isotretinoin is in a class of medications called retinoids. It works by slowing the production of certain natural substances that can cause acne.
Isotretinoin comes as a capsule to take by mouth. Isotretinoin is usually taken twice a day with meals for 4 to 5 months at a time. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take isotretinoin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the capsules whole with a full glass of liquid. Do not chew or suck on the capsules.
Your doctor will probably start you on an average dose of isotretinoin and increase or decrease your dose depending on how well you respond to the medication and the side effects you experience. Follow these directions carefully and ask your doctor or pharmacist if you are not sure how much isotretinoin you should take.
It may take several weeks or longer for you to feel the full benefit of isotretinoin. Your acne may get worse during the beginning of your treatment with isotretinoin. This is normal and does not mean that the medication is not working. Your acne may continue to improve even after you finish your treatment with isotretinoin.
Isotretinoin has been used to treat certain other skin conditions and some types of cancer. Talk to your doctor about the possible risks of using this medication for your condition.
