Sep 11, 2025

If your doctor has prescribed Danazol 100 mg, you may be dealing with a condition such as endometriosis, fibrocystic breast disease, or hereditary angioedema. Known for its ability to regulate hormones, danazol plays a powerful role in managing these health issues effectively.

In this article, we’ll explain what danazol 100 mg is, how it works, its uses, side effects, and why DANOZOLIS 100 by Steris Healthcare is a trusted brand among doctors and patients alike.

What is Danazol?

Danazol 100 mg is a synthetic steroid derived from ethisterone. It is known for its hormone-suppressing effects, especially on the pituitary gland. This action reduces the production of certain sex hormones, like estrogen and progesterone, making danazol extremely effective in treating hormone-sensitive conditions.

The brand DANOZOLIS 100, manufactured by Steris Healthcare, is trusted for its high-quality formulation, affordability, and clinical reliability.

Danazol 100 mg Uses

Doctors commonly prescribe tab danazol 100 to treat the following conditions:

  • Endometriosis – Helps reduce pelvic pain, inflammation, and abnormal tissue growth.

  • Fibrocystic Breast Disease – Reduces breast pain, tenderness, and nodules.

  • Hereditary Angioedema – Prevents episodes of severe swelling in the face, limbs, airways, or intestines.

  • Menorrhagia – In specific cases, danazol can help regulate heavy menstrual bleeding.

  • Hormone-related disorders – May be used in specific off-label cases like gynecomastia or precocious puberty.

How Does Danazol 100 mg Work?

Danazol works by suppressing the pituitary hormones (FSH and LH), which in turn reduces estrogen production in women and testosterone in men (in specific cases). This hormonal suppression leads to improvement in hormone-sensitive conditions.

In simple terms:

  • Less hormone production = Less inflammation, pain, and abnormal tissue growth

  • This makes danazol 100 especially effective for endometriosis and fibrocystic breast disease

Benefits of Danazol 100 mg Capsule

  • Reduces Endometriosis Symptoms: Provides relief from pelvic pain and menstrual discomfort.

  • Improves Breast Health: Helps shrink painful lumps and decreases tenderness in fibrocystic breast disease.

  • Prevents Swelling Episodes: Effective in preventing hereditary angioedema attacks.

  • Balances Hormones: Helps regulate excessive hormonal activity in the body.

  • Convenient Dosage: Available in capsule form for easy intake and compliance.

Danazol Mechanism of Action

Danazol 100 mg works by inhibiting the release of pituitary hormones that stimulate the ovaries. As a result, estrogen production is reduced, which helps control endometriosis and other hormone-driven conditions. Its mild androgenic effect also plays a role in preventing swelling in hereditary angioedema.
