Nafarelin

How it works

A nasal-spray GnRH copy: only a few percent reaches blood, yet enough to switch off the pituitary and estrogen. For endometriosis.

What it's made of

10 amino acids: GnRH with a D-naphthylalanine, a very fatty artificial amino acid, at position 6. More potent and longer-lasting than the natural hormone.

What it's for

Prescribed for

Endometriosis in adult women, for 6 months, and central precocious puberty in children.
