Danazol 100 mg | DANOZOLIS 100

Danazol 100mg is a synthetic steroid derived from ethisterone, belonging to a distinctive class of hormonal agents with combined weak androgenic, anabolic, and antiestrogenic properties. This lower-strength formulation offers physicians important flexibility in tailoring Danazol therapy — whether as an initiation dose for patients beginning treatment, a maintenance dose after successful symptom control at higher doses, or a standalone therapeutic dose for conditions requiring less aggressive hormonal suppression.

Under the brand name Danozolis 100, manufactured by Steris Healthcare, this formulation is prescribed by gynecologists, endocrinologists, and immunologists for patients requiring precise, individualized Danazol dosing.

Product Information

Why It's Important

The importance of precise, individualized dosing in Danazol therapy cannot be overstated, given the medication's distinctive androgenic side-effect profile. While Danazol remains a clinically valuable treatment for endometriosis, fibrocystic breast disease, and hereditary angioedema, physicians have long recognized that using the lowest effective dose is a central principle of safe, sustainable long-term Danazol therapy — minimizing androgenic side effects like weight gain, acne, and voice changes while still achieving meaningful symptom control.

This is precisely where Danozolis 100 plays a clinically important role. For fibrocystic breast disease, many patients achieve adequate relief from breast pain and nodularity at lower Danazol doses, making the 100mg strength a clinically appropriate starting point rather than automatically escalating to higher doses. Similarly, in hereditary angioedema prophylaxis, clinical practice has increasingly emphasized titrating down to the lowest dose that effectively controls attack frequency once initial control is established — a strategy that directly depends on having an appropriately sized lower-strength capsule available.

For endometriosis management, some patients — particularly those with milder symptoms or increased sensitivity to androgenic side effects — may achieve satisfactory symptom relief at 100mg dosing, avoiding the more pronounced side-effect burden sometimes associated with higher-dose regimens.

The clinical value of having a reliable, consistently manufactured 100mg formulation like Danozolis 100 is therefore significant — it supports the individualized, dose-minimizing approach that is now considered best practice in long-term Danazol therapy. The reliability of a WHO-GMP and ISO 9001:2018 certified manufacturer like Steris Healthcare further reinforces this, ensuring that patients on carefully titrated maintenance doses receive consistent, predictable therapeutic exposure batch after batch.

Key Benefits 

What Are the Benefits of Danazol 100?

Danazol 100mg, as formulated in Danozolis 100, offers several clinically meaningful advantages:

• Precise dose titration support: Provides physicians with a lower-strength option to fine-tune Danazol therapy, supporting the "lowest effective dose" principle central to safe long-term use.
• Effective relief from fibrocystic breast symptoms: Many patients achieve meaningful reduction in breast nodularity, tenderness, and cyclical pain at this strength, without necessarily requiring higher-dose therapy.
• Suitable maintenance dosing for hereditary angioedema: Once initial attack control is established, many patients can be successfully maintained on lower Danazol doses, reducing cumulative androgenic exposure over long-term prophylactic therapy.
• Gentler introduction to Danazol therapy: For patients beginning treatment, particularly those more sensitive to androgenic side effects, starting at 100mg can offer a more comfortable entry point into hormonal therapy.
• Reduced androgenic side-effect burden: Compared to higher-strength dosing, the 100mg strength is often associated with a milder side-effect profile, supporting better long-term tolerability and adherence.
• Oral convenience: As with other Danazol formulations, this capsule offers a non-invasive treatment route, supporting easier long-term adherence compared to injectable hormonal therapies.
• Well-characterized long-term clinical experience: Decades of clinical use across multiple Danazol strengths have generated a well-understood efficacy and safety profile, helping specialists make informed dosing decisions.
• Trusted manufacturing standards: Danozolis 100 is manufactured by Steris Healthcare, a WHO-GMP and ISO 9001:2018 certified pharmaceutical company, ensuring consistent potency and quality across every batch — particularly important for patients on carefully calibrated long-term maintenance therapy.

Side Effects 

Because Danazol has androgenic and antiestrogenic properties, its side effect profile is distinct from many other hormonal therapies, though often milder at this lower strength. Common side effects include:

• Weight gain
• Mild acne and oily skin
• Menstrual irregularities, including amenorrhea (absence of periods) during treatment
• Hot flushes
• Mild muscle cramps
• Headache
• Mild mood changes, including irritability
• Vaginal dryness

Most mild androgenic side effects are dose-dependent and tend to be less pronounced at the 100mg strength compared to higher doses, though they are still generally monitored closely by the prescribing physician throughout therapy.

Precautions & Warnings

Before starting Danazol 100, patients and prescribers should carefully consider the following precautions:

• Pregnancy: Danazol is contraindicated in pregnancy due to the risk of virilization of a female fetus. Effective non-hormonal contraception is required during treatment.
• Liver Disease: Should not be used in patients with significant hepatic impairment, given the drug's association with liver enzyme elevation and rare hepatotoxicity, even at lower doses.
• Cardiovascular and Renal Disease: Should be used cautiously in patients with pre-existing cardiac, renal, or hepatic dysfunction due to the risk of fluid retention.
• Breastfeeding: Danazol is generally not recommended during breastfeeding due to potential effects on the infant.
• Androgen-Sensitive Conditions: Should be avoided in patients with androgen-dependent tumors or a history of such conditions.
• Diabetes: Danazol may affect glucose tolerance, so blood sugar should be monitored closely in diabetic patients.
• Migraine or Epilepsy: Caution advised, as fluid retention associated with Danazol may worsen these conditions in susceptible individuals.
• Drug Interactions: Caution is required when co-administering with anticoagulants (Danazol can enhance the effect of warfarin), insulin or oral hypoglycemics, carbamazepine, and certain statins.
• Regular Monitoring: Periodic liver function tests and clinical assessment are recommended throughout the course of treatment, even at lower doses and during long-term maintenance therapy.

Mechanism of Action 

Danazol 100mg exerts its therapeutic effects through the same multifaceted hormonal mechanism as higher Danazol strengths, delivered at a lower dose to achieve appropriate therapeutic effect with reduced androgenic exposure:

1. Suppression of the Hypothalamic-Pituitary-Ovarian Axis: Danazol inhibits the pituitary release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), reducing ovarian estrogen and progesterone production, creating a relatively hypoestrogenic hormonal environment even at this lower dose.
2. Direct Action on Endometrial and Breast Tissue: Danazol binds directly to androgen, progesterone, and glucocorticoid receptors in endometrial and breast tissue, contributing to symptom relief independent of its systemic hormonal suppression.
3. Increased Hepatic Synthesis of C1 Esterase Inhibitor: In hereditary angioedema, Danazol stimulates hepatic production of C1 esterase inhibitor and complement component C4 — an effect that can often be sustained at lower maintenance doses once initial control is achieved.
4. Weak Androgenic and Anabolic Activity: At the 100mg strength, Danazol's androgenic activity is present but generally produces a milder side-effect profile compared to higher doses, while still contributing to therapeutic benefit.
5. Sex Hormone-Binding Globulin (SHBG) Modulation: Danazol reduces SHBG levels, increasing free testosterone availability, contributing to its overall hormonal effect profile even at this lower dose.

This dose-flexible mechanism is what allows Danazol 100 to serve as both an effective standalone therapeutic dose for milder presentations and a strategic maintenance or titration dose within a broader, individualized treatment plan.
