Pregnyl

Clinical summary

Indications and usage INDICATIONS AND USAGE HCG HAS NOT BEEN DEMONSTRATED TO BE EFFECTIVE ADJUNCTIVE THERAPY IN THE TREATMENT OF OBESITY. THERE IS NO SUBSTANTIAL EVIDENCE THAT IT INCREASES WEIGHT LOSS BEYOND THAT RESULTING FROM CALORIC RESTRICTION, THAT IT CAUSES A MORE ATTRACTIVE OR “NORMAL” DISTRIBUTION OF FAT, OR THAT IT DECREASES THE HUNGER AND DISCOMFORT ASSOCIATED WITH CALORIE-RESTRICTED DIETS. Prepubertal cryptorchidism not due to anatomical obstruction. In general, hCG is thought to induce testicular descent in situations when descent would have occurred at puberty. hCG thus may help predict whether or not orchiopexy will be needed in the future. Although, in some cases, descent following hCG administration is permanent, in most cases, the response is temporary. Therapy is usually instituted in children between the ages of 4 and 9. Selected cases of hypogonadotropic hypogonadism (hypogonadism secondary to a pituitary deficiency) in males. Induction of ovulation and pregnancy in the anovulatory, infertile woman in whom the cause of anovulation is secondary and not due to primary ovarian failure, and who has been appropriately treated with human gonadotropins. Dosage and administration DOSAGE AND ADMINISTRATION For intramuscular use only. Each multiple-dose vial is to be used for one patient. The dosage regimen employed in any particular case will depend upon the indication for the use, the age and weight of the patient, and the physician’s preference. The following regimens have been advocated by various authorities: Prepubertal cryptorchidism not due to anatomical obstruction. Generally, institute therapy in children between the ages of 4 and 9. 4000 USP units 3 times weekly for 3 weeks. 5000 USP units every second day for 4 injections. 15 injections for 500 to 1000 USP units over a period of 6 weeks. 500 USP units 3 times weekly for 4 to 6 weeks. If this course of treatment is not successful, another series is begun 1 month later, giving 1000 USP units per injection. Selected cases of hypogonadotropic hypogonadism in males. 500 to 1000 USP units 3 times a week for 3 weeks, followed by the same dose twice a week for 3 weeks. 4000 USP units 3 times weekly for 6 to 9 months, following which the dosage may be reduced to 2000 USP units 3 times weekly for an additional 3 months. Induction of ovulation and pregnancy in the anovulatory, infertile woman in whom the cause of anovulation is secondary and not due to primary ovarian failure and who has been appropriately treated with gonadotropins. (See also prescribing information for gonadotropins for dosage and administration for that drug product .) 5000 to 10,000 USP units 1 day following the last dose of gonadotropins. (A dosage of 10,000 USP units is recommended in the labeling for gonadotropins.) Directions for Reconstitution Withdraw sterile air from vial with lyophilized powder and inject into vial with solvent. Remove 1 to 10 mL of solvent and add to vial with lyophilized powder; agitate gently until powder is completely dissolved in solution. Do not shake. PREGNYL is a white, dry powder / cake. The solvent is a clear and colorless aqueous solution. Visually inspect parenteral drug products for particulate matter and discoloration prior to administration, whenever solution and container permit. If there is a discoloration or particulates, do not use. IMPORTANT: IF NEEDED, THE RECONSTITUTED SOLUTION IS STABLE FOR 60 DAYS WHEN REFRIGERATED. DO NOT FREEZE. USE THE RECONSTITUTED SOLUTION WITHIN 60 DAYS OF RECONSTITUTION. IF THE RECONSTITUTED SOLUTION IS NO LONGER NEEDED, DISCARD UNUSED PORTION. Warnings and cautions WARNINGS Use hCG in conjunction with gonadotropin therapy only if the physician is experienced with infertility problems and is familiar with the criteria for patient selection, contraindications, warnings, precautions, and adverse reactions described in the package insert for gonadotropins. Gonadotropin therapy, including hCG, requires a certain time commitment by physicians and supportive health professionals, and requires the availability of appropriate monitoring facilities (see PRECAUTIONS/Laboratory Tests ). Safe and effective induction of ovulation with use of PREGNYL requires monitoring of ovarian response with serum estradiol and transvaginal ultrasound on a regular basis. Anaphylaxis Anaphylaxis has been reported with urinary-derived hCG products. Ovarian Hyperstimulation Syndrome (OHSS) Ovarian Hyperstimulation Syndrome (OHSS) is a medical event distinct from uncomplicated ovarian enlargement and may progress rapidly to become a serious medical event. OHSS is characterized by a dramatic increase in vascular permeability, which can result in a rapid accumulation of fluid in the peritoneal cavity, thorax, and potentially, the pericardium. The early warning signs of the development of OHSS are severe pelvic pain, nausea, vomiting, and weight gain. Abdominal pain, abdominal distension, gastrointestinal symptoms including nausea, vomi
