This drug can be used with contraceptives, starting Synarel approximately when the patient has taken 18 tablets, or without contraceptives, starting its use on day 21 of the previous cycle. Sometimes, when used without contraceptives, it can cause the period to be delayed for a few days, but usually it does not.

Synarel is a drug used in IVF stimulation protocols. Its active ingredient is Nafarelin, a GnRH (gonadotropin-releasing hormone) agonist. Its function is to act on the pituitary gland by decreasing the normal response to GnRH, thereby inhibiting endogenous FSH and LH production, thus keeping the ovaries at rest.
