Indications and Usage
Ganirelix Acetate Injection is indicated for the inhibition of premature LH surges in women undergoing controlled ovarian hyperstimulation.
Dosage and Administration
After initiating FSH therapy on Day 2 or 3 of the cycle, Ganirelix Acetate Injection 250 mcg may be administered subcutaneously once daily during the mid to late portion of the follicular phase. By taking advantage of endogenous pituitary FSH secretion, the requirement for exogenously administered FSH may be reduced. Treatment with Ganirelix Acetate should be continued daily until the day of hCG administration. When a sufficient number of follicles of adequate size are present, as assessed by ultrasound, final maturation of follicles is induced by administering hCG. The administration of hCG should be withheld in cases where the ovaries are abnormally enlarged on the last day of FSH therapy to reduce the chance of developing OHSS (Ovarian Hyperstimulation Syndrome). Directions for Using Ganirelix Acetate Injection Ganirelix Acetate Injection is supplied in a single dose, sterile, prefilled syringe and is intended for SUBCUTANEOUS administration only. Air bubble(s) may be seen in the pre-filled syringe. This is expected, and removal of the air bubble(s) is not needed. Wash hands thoroughly with soap and water. The most convenient sites for SUBCUTANEOUS injection are in the abdomen around the navel or upper thigh. The injection site should be swabbed with a disinfectant to remove any surface bacteria. Clean about two inches around the point where the needle will be inserted and let the disinfectant dry for at least one minute before proceeding. With syringe held upward, remove needle cover. Pinch up a large area of skin between the finger and thumb. Vary the injection site a little with each injection. The needle should be inserted at the base of the pinched-up skin at an angle of 45-90° to the skin surface. When the needle is correctly positioned, it will be difficult to draw back on the plunger. If any blood is drawn into the syringe, the needle tip has penetrated a vein or artery. If this happens, withdraw the needle slightly and reposition the needle without remov

Adverse Reactions
The safety of Ganirelix Acetate Injection was evaluated in two randomized, parallel-group, multicenter controlled clinical studies. Treatment duration for Ganirelix Acetate ranged from 1 to 14 days. Table IV represents adverse events (AEs) from first day of Ganirelix Acetate administration until confirmation of pregnancy by ultrasound at an incidence of ≥ 1% in Ganirelix Acetate-treated subjects without regard to causality. TABLE IV: Incidence of common adverse events (Incidence ≥ 1% in Ganirelix Acetate-treated subjects). Completed controlled clinical studies (All-subjects-treated group). Adverse Events Occurring in ≥ 1% Ganirelix Acetate N=794 % (n) Abdominal Pain (gynecological) 4.8 (38) Death Fetal 3.7 (29) Headache 3.0 (24) Ovarian Hyperstimulation Syndrome 2.4 (19) Vaginal Bleeding 1.8 (14) Injection Site Reaction 1.1 (9) Nausea 1.1 (9) Abdominal Pain (gastrointestinal) 1.0 (8) During post-marketing surveillance, rare cases of hypersensitivity reactions, including anaphylaxis (including anaphylactic shock), angioedema and urticaria have been reported with Ganirelix Acetate, as early as with the first dose (see PRECAUTIONS).
