Initially, 75-150 IU daily via IM or SC inj for at least 7 days. May increase dose if necessary, by 37.5 IU (up to 75 IU) at intervals of 7 or 14 days according to clinical monitoring and individual response. Max: 225 IU daily. Discontinue the cycle if patient fails to adequately respond after 4 weeks of treatment and may recommence at a higher initial dose. Alternatively, initiate at 150 IU once daily via IM or SC inj for 5 days, adjusted in increments of 75-150 IU per adjustment at intervals of at least 2 days according to clinical monitoring and individual response. Max: 450 IU daily. Max treatment duration: 12 days. If an optimal response is obtained, administer 5,000-10,000 IU hCG as a single inj 24-48 hours after the last urofollitropin dose. If an excessive response is obtained, discontinue treatment and withhold hCG administration. Further patient instructions and monitoring may be required based on individual ovarian response. Dosage recommendations may vary among countries and individual products. Refer to local detailed product guidelines.
