When determining the most appropriate dosage of Amnesteem, your healthcare provider will take into consideration how much you weigh, the severity of your acne, and how you respond to the drug. This prescription medication comes as a capsule and is taken twice daily. Each dose should be taken with food to help increase its absorption. Amnesteem is usually taken for 15 to 20 weeks.
An Introduction to Your Dosage of AmnesteemThe dose of Amnesteem® (isotretinoin) your healthcare provider recommends will vary, depending mostly on your weight, although the severity of your acne and your response to the drug will also influence your recommended dosage. As is always the case, do not adjust this amount unless your healthcare provider specifically tells you to do so.
Amnesteem Dosing Guidelines for AcneIn most cases, the recommended dose of Amnesteem is 0.5 mg to 1 mg per kg of body weight (about 0.23 mg to 0.45 mg per lb) taken each day, divided into two daily doses. For adults with severe acne or acne limited mostly to the trunk of the body, a dose of 2 mg per kg (about 0.91 mg per lb) each day, divided into two daily doses, may be necessary. Your healthcare provider may adjust this amount as necessary, especially if you develop bothersome Amnesteem side effects.
In most cases, Amnesteem is taken for 15 to 20 weeks. Your acne will continue to improve after you stop taking the medication. In fact, if your acne drastically improves before 15 to 20 weeks of treatment, your healthcare provider might recommend that you stop taking it early.
In some cases, a second course of treatment is necessary. A second course may be recommended if your acne is still a problem eight weeks after finishing the first course.
You will not be able to get more than a 30-day supply of Amnesteem at a time. Each time you need more, you will need a new prescription and a new authorization from the iPLEDGE program (the program designed to prevent birth defects caused by Amnesteem). If you are a woman of childbearing potential, you will need to have a negative pregnancy test every month (done by a laboratory) and must use two different forms of birth control.
