Duphaston Tablet – Uses, Dosage, Side Effects and more

Duphaston is a medication that contains dydrogesterone, a synthetic hormone similar to the naturally occurring female hormone progesterone. It is commonly prescribed for various gynecological and reproductive conditions. This comprehensive guide will provide detailed information about Duphaston, including its uses, dosage, side effects, and more.

What is Duphaston?

Duphaston (dydrogesterone) is a synthetic progestogen that mimics the action of natural progesterone. It is used to treat a variety of conditions related to hormonal imbalance in women, particularly those involving progesterone deficiency. Unlike some other synthetic progestogens, dydrogesterone does not have androgenic, estrogenic, or corticoid effects, making it a favorable option for many patients.

Uses of Duphaston

1. Menstrual Disorders

Duphaston is commonly prescribed for various menstrual disorders, including:

• Dysmenorrhea: Painful menstruation.
• Irregular Menstrual Cycles: Including oligomenorrhea (infrequent periods) and amenorrhea (absence of periods).

2. Premenstrual Syndrome (PMS)

Duphaston helps alleviate the symptoms of PMS, such as mood swings, irritability, and bloating, by regulating hormone levels.

3. Endometriosis

Endometriosis is a condition where tissue similar to the lining inside the uterus grows outside the uterus, causing pain and irregular bleeding. Duphaston helps manage these symptoms by regulating the growth of endometrial tissue.

4. Infertility and Luteal Phase Support

Duphaston is often used in fertility treatments to support the luteal phase (the second half of the menstrual cycle) and increase the chances of successful implantation and pregnancy.

5. Threatened or Recurrent Miscarriage

For women experiencing threatened miscarriage or recurrent miscarriages, Duphaston provides progesterone support, which is crucial for maintaining pregnancy.

6. Hormone Replacement Therapy (HRT)

In postmenopausal women undergoing estrogen replacement therapy, Duphaston is used to counteract the effects of estrogen on the endometrium and prevent endometrial hyperplasia (excessive growth of the uterine lining).

How Duphaston Works

Duphaston works by supplementing the body with dydrogesterone, which acts similarly to natural progesterone. Progesterone is essential for regulating the menstrual cycle, maintaining the uterine lining for pregnancy, and supporting early pregnancy. By mimicking the effects of natural progesterone, Duphaston helps to restore hormonal balance and alleviate symptoms associated with progesterone deficiency.
