The Gonal-f® Multi-Dose Vial contains a manufactured version of a hormone found naturally in the body called follicle-stimulating hormone (FSH). FSH, in combination with another hormone called LH (luteinizing hormone), is responsible for the growth of eggs in the ovaries during the menstrual cycle. Gonal-f® is prescribed to women as a daily subcutaneous (under the skin) injection for approximately 8-12 days to help stimulate the growth and maturation of multiple eggs during fertility treatment such as IVF. It may also be prescribed to men to help improve sperm production.
The Gonal-f® Multi-Dose Vial contains powdered medication that must be mixed with bacteriostatic water before injecting. Each Gonal-f® Multi-Dose Vial comes with specially marked injection syringes to ensure the correct dose of medication is administered.
