Ovidrel (Choriogonadotropin)

What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

    Description

    Ovidrel is a recombinant form of human chorionic gonadotropin (choriogonadotropin alfa), indicated for the induction of final follicular maturation and triggering of ovulation in women undergoing assisted reproductive technologies (ART) such as in vitro fertilization (IVF), or for ovulation induction in anovulatory or oligo-ovulatory patients. Produced using recombinant DNA technology, Ovidrel mimics the natural luteinizing hormone (LH) surge that initiates ovulation. It is administered as a single subcutaneous injection and is widely used in fertility treatment protocols.

    Directions

    Ovidrel is administered as a single subcutaneous injection of 250 micrograms, typically 24 to 36 hours before the scheduled time of oocyte retrieval or timed intercourse. The injection should be given under the supervision of a fertility specialist, and proper training in injection technique should be provided if self-administered at home. Timing is critical and should follow ovarian stimulation and follicular monitoring to ensure optimal results.

    Ingredients

    Each prefilled syringe of Ovidrel contains:

    • Choriogonadotropin alfa 250 micrograms (equivalent to approximately 6,500 IU)
    • Excipients: mannitol, L-methionine, poloxamer 188, phosphoric acid (for pH adjustment), and water for injection

    Contraindications

    Ovidrel is contraindicated in patients with:

    • Hypersensitivity to choriogonadotropin alfa or any component of the formulation
    • Primary ovarian failure or ovarian cysts unrelated to polycystic ovary syndrome
    • Uncontrolled thyroid or adrenal dysfunction
    • Pituitary or hypothalamic tumors
    • Known or suspected hormone-dependent tumors
    • Pregnancy or breastfeeding

    Cautions

    Use of Ovidrel can increase the risk of ovarian hyperstimulation syndrome (OHSS), especially in women with polycystic ovary syndrome or high estradiol levels. Patients should be monitored carefully with ultrasound and serum estradiol measurements. Ovidrel does not prevent pregnancy, and multiple gestations may occur. The product should only be used under the care of a specialist experienced in infertility treatment.

    Common and potential side effects include:

    • Abdominal pain or bloating
    • Nausea or vomiting
    • Injection site reactions such as redness, swelling, or discomfort
    • Headache or fatigue
    • Breast tenderness
    • Ovarian hyperstimulation syndrome (OHSS), in moderate to severe cases
    • Rarely, allergic reactions or thromboembolic events
