Product Overview & Brand Variants

INN and Brand Names Used in Canada

In Canada, Duphaston represents the brand name for the International Nonproprietary Name (INN) known as dydrogesterone. The medication is available as oral tablets of 10 mg, typically packaged in blisters of 20 tablets. This formulation is popular among healthcare providers for its efficacy in various hormone-related conditions.

Legal Classification Under Health Canada

Duphaston is classified as a prescription-only medication under Canadian regulations. This classification emphasizes the need for professional oversight when using the drug. Consequently, patients cannot obtain it over the counter. Those interested in using Duphaston must consult healthcare professionals to receive an appropriate prescription, ensuring safe and effective treatment.

Indications in Local Canadian Medical Practice

Approved Uses

Health Canada has approved Duphaston primarily for use in reproductive health. Its indications span across conditions such as secondary amenorrhea, dysmenorrhea, and luteal phase support in infertility treatments. The efficacy data supporting its use in these areas makes Duphaston a trusted choice for healthcare practitioners managing patients with hormonal issues.

Off-label Patterns in Canadian Healthcare

While Duphaston is primarily prescribed for approved uses, there are common off-label practices in Canadian healthcare. For example, some practitioners may prescribe it for conditions like premenstrual syndrome (PMS) or to assist in regulating menstrual cycles. Guidelines exist that help healthcare providers navigate these off-label uses, emphasizing the importance of monitoring patient responses closely.

How It Works in the Body

Layman’s Explanation

Duphaston operates by mimicking the action of progesterone, a hormone vital for regulating menstruation and maintaining pregnancy. By balancing hormone levels, it can alleviate symptoms of hormonal imbalance and support the reproductive system effectively.

Clinical Detail from Health Canada Resources

According to Health Canada's clinical pharmacology resources, dydrogesterone primarily acts on the endometrium to prepare it for a possible pregnancy and regulate the menstrual cycle. Further insights reveal that it does not exhibit androgenic or estrogenic effects, making it a preferable choice in certain reproductive health situations.

Dosage & Administration

Standard regimens per Canadian guidelines

Understanding the correct dosage of Duphaston (dydrogesterone) is crucial for effective treatment. According to Canadian healthcare recommendations, the following dosages are standard for various conditions:

• Secondary amenorrhea: 10 mg twice daily during days 11-25 of the cycle.
• Infertility due to luteal insufficiency: 10 mg daily from day 14-25 of the cycle.
• Dysfunctional uterine bleeding: 10 mg twice daily for about 5-7 days.
• Threatened abortion: Starting dose of 40 mg, then 10 mg every 8 hours.
• Habitual abortion: 10 mg daily through at least the 20th week of pregnancy.
• Endometriosis: 10–20 mg daily during cycle days 5-25 or continuous use.
• Dysmenorrhea and PMS: 10 mg twice daily for days 5-25 of the cycle.

These regimens play a significant role in managing reproductive health effectively.

Adjustments by patient type

Dosage adjustments may be necessary based on specific patient populations, particularly in Canada. For the elderly or those with liver impairment, careful monitoring is required.

• Elderly: There's no established dosage guideline; use cautiously.
• Liver impairment: Duphaston isn't recommended for severe liver disease, as it may interfere with metabolism.

This thoughtful approach ensures safety and efficacy tailored to individual health conditions.
