Once a doctor decides a patient is a candidate for isotretinoin, they will counsel the patient to ensure the patient understands the drug and the potential side effects. Once the patient signs the necessary paperwork, their doctor will give them a patient ID number and ID card, as well as other program educational materials. After they have been registered in iPLEDGE by their doctor, they will receive their password in the mail after 5–10 business days. Patients are classified either as females of child-bearing potential (FCBPs), females not of child-bearing potential (FnCBPs), or males.
