IPLEDGE program
Although the goal of the program is to prevent pregnancies of women who take the drug, male patients must also participate in anti-pregnancy restrictions, primarily due to fears that male isotretinoin users might share their prescriptions with females without their physicians' knowledge. There has been no link to birth defects from Accutane associated with males using the drug, though male sexual dysfunction has been suggested by one study. As this has not been conclusively proven, this is not acknowledged as a side effect in the official literature accompanying the medication.
Controlled Drug in the United Kingdom
Substances subject to the full controlled drug requirements; e.g. diamorphine (heroin), pethidine, cocaine, methadone, methylphenidate, dextroamphetamine, fentanyl and oxycodone. Under the Act, a prescription for these drugs need to show full details including the form and strength of the preparation, with the total quantity written out in both words and figures. It is an offence for a doctor to issue an incomplete prescription or for a pharmacist to dispense a controlled drug unless all the required details are given.
