The dose of this medication varies according to individual response.
To help induce ovulation, the recommended initial dose of follitropin beta is 50 IU given daily, usually for 7 to 14 days. The dose may be adjusted according to response, which is measured by an ultrasound or by a blood test. When an adequate response is achieved, this medication is stopped and another medication, human chorionic gonadotropin (hCG), is given to induce ovulation.
For ART procedures, the usual initial dose is 150 IU to 225 IU daily for 4 days. The dose is then adjusted according to response and is usually continued for 6 to 12 days. When an adequate response is achieved, this medication is stopped and another medication, hCG, is given to induce ovulation.
In men, the usual dose is 150 IU given 3 times a week or 225 IU twice a week. Treatment is usually given for at least 3 to 4 months. It is usually given along with another medication, hCG.
The injections can be given under the skin (subcutaneous) or into a muscle (intramuscular) in women and under the skin (subcutaneous) in men. The best place for subcutaneous injections is around the navel or the upper thigh. The place of injection should be varied for each injection. The best place for intramuscular injections is the upper outer part of the buttock muscle.

Blood clots: This medication may increase the risk of blood clots, especially if you are already at risk of blood clots.

Multiple births: This medication may increase the risk of multiple births (mostly twins). Talk to your doctor about the risks of multiple births before beginning treatment.
Ovarian enlargement: Some women using this medication may experience ovarian enlargement associated with abdominal bloating or pain. In most cases, the pain and bloating stop without treatment within 2 or 3 weeks. If you experience these symptoms, contact your doctor.
Ovarian hyperstimulation syndrome (OHSS): Treatment with this medication can cause a condition called ovarian hyperstimulation syndrome (OHSS). With OHSS, too many follicles grow and cause abdominal or pelvic discomfort or pain, nausea, vomiting, and weight gain. Some women may experience difficulty breathing, diarrhea, and decreased urination. OHSS can progress rapidly and may become serious. It can occur even after treatment has stopped. If you experience any of these symptoms, contact your doctor immediately.
