Brug af GONAL- f samtidig med andre ovulationsstimulerende midler (hCG, clomifen citrat) kan forstærke follikelresponset, mens samtidig GnRH- agonist eller antagonist induceret hypofysedesensibilisering kan øge den dosis af GONAL- f, der er nødvendig for at opnå et adækvat ovarierespons.
Concomitant use of GONAL-f with other agents used to stimulate ovulation (e. g. hCG, clomiphene citrate) may potentiate the follicular response, whereas concurrent use of a GnRH agonist or antagonist to induce pituitary desensitisation may increase the dosage of Gonal-f needed to elicit an adequate ovarian response.
