What Is Isotretinoin?

Isotretinoin is used to treat the most severe form of acne (nodular acne) that cannot be cleared up by any other acne treatments, including antibiotics. Isotretinoin is only for patients who understand and agree to carry out all the instructions in the iPLEDGE program, because isotretinoin can cause serious side effects.

Who Should Not Take Isotretinoin?

Isotretinoin should NOT be used by pregnant women.

Do not take isotretinoin if you are:

• Breast-feeding
• Allergic to anything in it. Isotretinoin contains parabens, which are used as preservatives in the gelatin capsule.

What Should I Do Before Taking Isotretinoin?

• Tell your healthcare professional if you or someone in your family has had any kind of mental problems, asthma, liver disease, diabetes, heart disease, osteoporosis (bone loss), weak bones, an eating problem called anorexia nervosa (where people eat too little), or any food or medicine allergies.
   
• By March 1, 2006, all patients must be registered and activated by their doctors in iPLEDGE to get isotretinoin. You must sign the Patient Information/Informed Consent form.
   
• You must agree to or follow all the instructions in the iPLEDGE program.
   
• By March 1, 2006, only prescriptions from iPLEDGE doctors will be filled by iPLEDGE pharmacies.
   
• If you have sex anytime without using 2 forms of effective birth control, get pregnant, or miss your expected period, stop using isotretinoin and call your doctor right away.

Are There Any Interactions With Drugs Or Foods?

Tell your healthcare professional about all the medicines you take, including prescription and nonprescription medicines, vitamins, and herbal supplements. Isotretinoin and other medicines may affect each other sometimes causing serious side effects. Especially tell your healthcare professional if you take:

• Progestin-only containing birth control pills (“minipills”)
• Vitamin A supplements
• Tetracycline medicines
• Dilantin (phenytoin)
• Corticosteroid medicines
• St. John’s Wort

Is There Anything Else I Need to Know?

• Do not give blood while you take isotretinoin and for 1 month after stopping Isotretinoin. If someone who is pregnant gets your donated blood, her baby may be exposed to isotretinoin and may be born with birth defects.
• Do not drive at night until you know if isotretinoin has affected your vision. Do not have cosmetic procedures to smooth your skin, including waxing, dermabrasion, or laser procedures, while you are using isotretinoin and for at least 6 months after you stop. Isotretinoin can increase your chance of scarring from these procedures.
• Avoid sunlight and ultraviolet lights as much as possible. Tanning machines use ultraviolet lights.
• Do not share isotretinoin with other people. It can cause serious birth defects and other serious health problems.
• You will only be able to get up to a 30-day supply of isotretinoin at one time. Refills will require you to get a new prescription from your doctor. The prescription must be filled within 7 days of your office visit.  
• You should receive an isotretinoin Medication Guide each time you receive isotretinoin. This is required by law.
