Before taking Amnesteem

Amnesteem can cause miscarriage, premature birth, severe birth defects, or death of a baby if the mother takes this medicine at the time of conception or during pregnancy. Even one dose of isotretinoin can cause major birth defects of the baby's ears, eyes, face, skull, heart, and brain. Never use this medicine if you are pregnant or able to become pregnant.

For Women: Unless you have had your uterus and ovaries removed (total hysterectomy with oophorectomy) or have been in menopause for at least 12 months in a row, you are considered to be able to get pregnant. You must have 2 negative pregnancy tests before you start taking Amnesteem, before each prescription is refilled, right after you take your last dose of isotretinoin, and again 30 days later. All pregnancy testing is required by the iPLEDGE program.

You must agree in writing to use two specific forms of birth control beginning 30 days before you start taking Amnesteem and ending 30 days after your last dose. Both a primary and a secondary form of birth control must be used together.

Primary forms of birth control include:

tubal ligation (tubes tied);

vasectomy of the male sexual partner;

an IUD (intrauterine device);

estrogen-containing birth control pills (not mini-pills); and

hormonal birth control patches, implants, injections, or vaginal ring.

Secondary forms of birth control include:

a male latex condom with or without spermicide;

a diaphragm plus a spermicide;

a cervical cap plus a spermicide; and

a vaginal sponge containing a spermicide.

Stop using Amnesteem and call your doctor at once if you have unprotected sex, if you quit using birth control, if your period is late, or if you think you might be pregnant. If you get pregnant while taking this medicine, call the iPLEDGE pregnancy registry at 1-866-495-0654.

Not having sexual intercourse (abstinence) is the most effective method of preventing pregnancy.

You should not use Amnesteem if you are allergic to it.

Tell your doctor if you have ever had:

depression or mental illness;

asthma;

liver disease;

diabetes;

heart disease or high cholesterol;

osteoporosis or low bone mineral density;

an eating disorder such as anorexia;

a food or drug allergy; or

an intestinal disorder such as inflammatory bowel disease or ulcerative colitis.

Do not breastfeed.

Not approved for use by anyone younger than 12 years old.

How to use Amnesteem

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Each prescription of isotretinoin must be filled within 7 days of the date it was written by your doctor. You will receive no more than a 30-day supply of isotretinoin at one time.

Always take Amnesteem with a full glass of water. Do not chew or suck on the capsule. Swallow it whole.

Follow all directions about taking Amnesteem with or without food.

Use Amnesteem for the full prescribed length of time. Your acne may seem to get worse at first, but should then begin to improve.

You may need frequent blood tests.

Never share this medicine with another person, even if they have the same symptoms you have.

Store at room temperature away from moisture, heat, and light.

Warnings

Amnesteem in just a single dose can cause severe birth defects or death of a baby. Never use Amnesteem if you are pregnant or able to become pregnant.

You must have a negative pregnancy test before taking Amnesteem. You will also be required to use two forms of birth control to prevent pregnancy while taking this medicine. Stop using this medicine and call your doctor at once if you think you might be pregnant.

What other drugs will affect Amnesteem

Tell your doctor about all your other medicines, especially:

phenytoin;

St. John's wort (may make birth control pills less effective);

vitamin or mineral supplements;

progestin-only birth control pills (mini-pills, may not work as well when taken with Amnesteem);

steroid medicine; or

a tetracycline antibiotic, including doxycycline or minocycline.

This list is not complete. Other drugs may affect Amnesteem, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.
