Ivf-m

Uses

Ivf-m injection is used for the induction of final follicular maturation and early luteinization in infertile women who have undergone pituitary desensitization and who have been appropriately pretreated with follicle stimulating hormones as part of an Assisted Reproductive Technology (ART) program such as in vitro fertilization and embryo transfer. Ivf-m PreFilled Syringe is also used for the induction of ovulation (OI) and pregnancy in anovulatory infertile patients in whom the cause of infertility is functional and not due to primary ovarian failure.

Selection Of Patients:

• Before treatment with gonadotropins is instituted, a thorough gynecologic and endocrinologic evaluation must be performed. This should include an assessment of pelvic anatomy. Patients with tubal obstruction should receive Choriogonadotropin Alfa PreFilled Syringe only if enrolled in an in vitro fertilization program.
• Primary ovarian failure should be excluded by the determination of gonadotropin levels.
• Appropriate evaluation should be performed to exclude pregnancy.
• Patients in later reproductive life have a greater predisposition to endometrial carcinoma as well as a higher incidence of anovulatory disorders. A thorough diagnostic evaluation should always be performed in patients who demonstrate abnormal uterine bleeding or other signs of endometrial abnormalities before starting FSH and Choriogonadotropin Alfa PreFilled Syringe therapy.
• Evaluation of the partner's fertility potential should be included in the initial evaluation.

Ivf-m is also used to associated treatment for these conditions: Assisted Reproductive Technology therapy, Ovulation induction therapy

How Ivf-m works

Ivf-m binds to the Follicle stimulating hormone receptor which results in ovulation in the absence of sufficient endogenous Luteinizing hormone.

Dosage

Ivf-m dosage

Infertile Women Undergoing Assisted Reproductive Technologies (ART): Choriogonadotropin Alfa PreFilled Syringe 250 μg should be administered one day following the last dose of the follicle stimulating agent. Choriogonadotropin Alfa PreFilled Syringe should not be administered until adequate follicular development is indicated by serumestradioland vaginal ultrasonography. Administration should be withheld in situations where there is an excessive ovarian response, as evidenced by clinically significant ovarian enlargement or excessive estradiol production.

Infertile Women Undergoing Ovulation Induction (OI): Choriogonadotropin Alfa PreFilled Syringe should not be administered until adequate follicular development is indicated by serum estradiol and vaginal ultrasonography. Choriogonadotropin Alfa PreFilled Syringe 250 μg should be administered one day following the last dose of the follicle stimulating agent. Choriogonadotropin Alfa PreFilled Syringe administration should be withheld in situations where there is an excessive ovarian response, as evidenced by multiple follicular development, clinically significant ovarian enlargement or excessive estradiol production.

For Subcutaneous Use Only. Directions For Administration Of Choriogonadotropin Alfa Prefilled Syringe is intended for a single subcutaneous injection. Any unused material should be discarded. Choriogonadotropin Alfa PreFilled Syringe may be self-administered by the patient. Follow the directions below for injecting Choriogonadotropin Alfa PreFilled Syringe.

Step 1: Wash your hands thoroughly with soap and water.

Step 2: Carefully clean the injection site: Make yourself comfortable by sitting or lying down. Carefully clean the injection site on the stomach with an alcohol wipe and allow it to air-dry.

Step 3: Administer your injection: Carefully remove the needle cap from the syringe. Do not touch the needle or allow the needle to touch any surface. Inject the prescribed dose as directed by your doctor, nurse or pharmacist.

Step 4: Gently withdraw the needle: Discard the needle and syringe into your safety container. Place gauze over the injection site. If any bleeding occurs, apply gentle pressure. If bleeding does not stop within a few minutes, place a clean piece of gauze over the injection site and cover it with an adhesive bandage.

Step 5: Storage and clean up: Remember that your injection materials must be kept sterile and cannot be reused

Precaution

Gonadotropins, including Choriogonadotropin Alpha PreFilled Syringe (choriogonado-tropin alfa injection), should only be used by physicians who are thoroughly familiar with infertility problems and their management. Like other hCG products, Choriogonadotropin Alpha PreFilled Syringe is a potent gonadotropic substance capable of causing OvarianHyperstimulation Syndrome (OHSS) in women with or without pulmonary or vascularcomplications. The risks of gonadoptropin treatment should be considered for women with risk factors of thromboembolic events such as prior medical or family history. Gonadotropin therapy requires a certain time commitment by physicians and supportive health professionals, and requires the availability of appropriate monitoring facilities. Safe and effective induction of ovulation and use of Choriogonadotropin Alpha PreFilled Syringe in women requires monitoring of ovarian response with serum estradiol and transvaginal ultrasound on a regular basis.

Interaction

Drng & other interactions: No clinically significant drug interactions have been reported during hCG therapy. Following administration, Ovidrel (choriogonadotrophin alfa) may interfere for up to ten days with the immunological determination of serum/urinary hCG, leading to a false positive pregnancy test. During Ovidrel therapy, a minor thyroid stimulation is possible of which the clinical relevance is unknown.

Food Interaction

Volume of Distribution

• 5.9 ± 1.0 L

Elimination Route

The mean absolute bioavailability following a single subcutaneous injection to healthy female volunteers is about 40%.

Half Life

The mean terminal half-life is about 29 ± 6 hours (initial half-life is 4.5 ± 0.5 hours).

Clearance

• 0.29 +/- 0.04 L/h [healthy down-regulated females]

Elimination Route

One-tenth of the dose is excreted in the urine.

Pregnancy & Breastfeeding use

Pregnancy Category X. Intrauterine death and impaired parturition were observed in pregnant rats given a dose of urinary-hCG (500 IU) equivalent to three times the maximum human dose of 10,000, based on body surface area.

Nursing Mothers: It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised if hCG is administered to a nursing woman.

Contraindication

Choriogonadotropin Alpha PreFilled Syringe is contraindicated in women who exhibit:

• Prior hypersensitivity to hCG preparations or one of their excipients.
• Primary ovarian failure.
• Uncontrolled thyroid or adrenal dysfunction.
• An uncontrolled organic intracranial lesion such as a pituitary tumor.
• Abnormal uterine bleeding of undetermined origin
• Ovarian cyst or enlargement of undetermined origin
• Sex hormone dependent tumors of the reproductive tract and accessoryorgans.
• Pregnancy.
