Bemfola fixed dose pens potentially reduce drug wastage and associated costs of infertility treatment.

Bemfola is a recombinant follicle-stimulating hormone (FSH) used during infertility treatment. One main differentiator between FSH products is their delivery device; consisting of multi-dose pens (Gonal-f), vials or multi-dose preparations (Menopur), or adjustable daily disposable dose pens (Bemfola). To determine the potential impact of delivery device on drug wastage during infertility treatment this study retrospectively analysed Gonal-f and Menopur prescription and usage data from five UK clinics.
