Yuzpe Regimen - Formulations

Formulations

Many common combined oral contraceptive pills could be used for the Yuzpe regimen, although their manufacturers did not label the pills for this use. Such off-label use of approved medications is legal and commonplace in American medicine. Further, in February 1997, the FDA declared emergency contraceptive use of certain birth control pills, following the Yuzpe regimen, as safe and effective.

Yuzpe regimen dedicated products (Preven in US and Schering-PC4 in UK) were discontinued following the introduction of progestogen-only ECPs (Plan B in US and Levonelle in UK).
