the vial says for IM use only. is that not intermuscular??
Yes it does. take it intramuscular not subQ. If anyone can show me where it says you can take Human Chorionic Gonadotropin (HCG) subQ i'd like to see it.
DESCRIPTION
Human chorionic gonadotropin (HCG), a polypeptide hormone produced by the human placenta, is composed of an alpha and a beta sub-unit. The alpha sub-unit is essentially identical to the alpha sub-units of the human pituitary gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), as well as to the alpha sub-unit of human thyroid-stimulating hormone (TSH). The beta sub-units of these hormones differ in amino acid sequence.
PREGNYL® (chorionic gonadotropin for injection, USP) is a highly purified pyrogen-free preparation obtained from the urine of pregnant females. It is standardized by a biological assay procedure. It is available for intramuscular injection in multiple dose vials containing 10,000 USP Units of sterile dried powder with 5 mg monobasic sodium phosphate and 4.4 mg dibasic sodium phosphate. If required, pH is adjusted with sodium hydroxide and/or phosphoric acid. Each package also contains a 10 mL vial of solvent containing: water for injection with 0.56% sodium chloride and 0.9% BENZYL ALCOHOL, WHICH IS NOT FOR USE IN NEWBORNS. If required, pH is adjusted with sodium hydroxide and/or hydrochloric acid.
CLINICAL PHARMACOLOGY
The action of Human Chorionic Gonadotropin (HCG) is virtually identical to that of pituitary LH, although Human Chorionic Gonadotropin (HCG) appears to have a small degree of FSH activity as well. It stimulates production of gonadal steroid hormones by stimulating the interstitial cells (Leydig cells) of the testis to produce androgens and the corpus luteum of the ovary to produce progesterone.
Androgen stimulation in the male leads to the development of secondary sex characteristics and may stimulate testicular descent when no anatomical impediment to descent is present. This descent is usually reversible when Human Chorionic Gonadotropin (HCG) is discontinued. During the normal menstrual cycle, LH participates with FSH in the development and maturation of the normal ovarian follicle, and the mid-cycle LH surge triggers ovulation. Human Chorionic Gonadotropin (HCG) can substitute for LH in this function.
During a normal pregnancy, Human Chorionic Gonadotropin (HCG) secreted by the placenta maintains the corpus luteum after LH secretion decreases, supporting continued secretion of estrogen and progesterone and preventing menstruation. Human Chorionic Gonadotropin (HCG) HAS NO KNOWN EFFECT ON FAT MOBILIZATION, APPETITE OR SENSE OF HUNGER, OR BODY FAT DISTRIBUTION.
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.
1. Prepubertal cryptorchidism not due to anatomical obstruction. In general, Human Chorionic Gonadotropin (HCG) is thought to induce testicular descent in situations when descent would have occurred at puberty. Human Chorionic Gonadotropin (HCG) thus may help predict whether or not orchiopexy will be needed in the future. Although, in some cases, descent following Human Chorionic Gonadotropin (HCG) administration is permanent, in most cases, the response is temporary. Therapy is usually instituted in children between the ages of 4 and 9.
2. Selected cases of hypogonadotropic hypogonadism (hypogonadism secondary to a pituitary deficiency) in males.
3. 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 pretreated with human menotropins.
CONTRAINDICATIONS
Precocious puberty, prostatic carcinoma or other androgen-dependent neoplasm, prior allergic reaction to HCG.
WARNINGS
HCG should be used in conjunction with human menopausal gonadotropins only by physicians experienced with infertility problems who are familiar with the criteria for patient selection, contraindications, warnings, precautions, and adverse reactions described in the package insert for menotropins.
The principal serious adverse reactions during this use are: (1) Ovarian hyperstimulation, a syndrome of sudden ovarian enlargement, ascites with or without pain, and/or pleural effusion, (2) Rupture of ovarian cysts with resultant hemoperitoneum, (3) Multiple births, and (4) Arterial thromboembolism.
PRECAUTIONS
General
Since androgens may cause fluid retention, Human Chorionic Gonadotropin (HCG) should be used with caution in patients with cardiac or renal disease, epilepsy, migraine, or asthma.
Pediatric Use
Induction of androgen secretion by Human Chorionic Gonadotropin (HCG) may induce precocious puberty in pediatric patients treated for cryptorchidism. Therapy should be discontinued if signs of precocious puberty occur.
Geriatric Use
Clinical studies of PREGNYL® (chorionic gonadotropin for injection, USP) did not include subjects aged 65 and over.
ADVERSE REACTIONS
Headache, irritability, restlessness, depression, fatigue, edema, precocious puberty, gynecomastia, pain at the site of injection.
DOSAGE AND ADMINISTRATION
For intramuscular use only . 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. Therapy is usually instituted in children between the ages of 4 and 9.
4,000 USP Units three times weekly for three weeks.
5,000 USP Units every second day for four injections.
15 injections for 500 to 1,000 USP Units over a period of six weeks.
500 USP Units three times weekly for four to six weeks. If this course of treatment is not successful, another series is begun one month later, giving 1,000 USP Units per injection.
Selected cases of hypogonadotropic hypogonadism in males.
500 to 1,000 USP Units three times a week for three weeks, followed by the same dose twice a week for three weeks.
4,000 USP Units three times weekly for six to nine months, following which the dosage may be reduced to 2,000 USP Units three times weekly for an additional three 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 pretreated with human menotropins. (See prescribing information for menotropins for dosage and administration for that drug product.)
5,000 to 10,000 USP Units one day following the last dose of menotropins. (A dosage of 10,000 USP Units is recommended in the labeling for menotropins.)
Directions for Reconstitution
