Danazol
Danazol
- In our pharmacy, you can buy danazol without a prescription, with delivery available in Australia. It is also a prescription-only medicine in major markets, so availability may vary depending on local supply and regulations.
- Danazol is used for endometriosis, fibrocystic breast disease, and prophylaxis of hereditary angioedema. It works as a synthetic androgen with antigonadotropic effects, reducing pituitary gonadotropin release and lowering ovarian hormone activity.
- The usual dose of danazol is 200–800 mg per day for endometriosis, 100–400 mg per day for fibrocystic breast disease, and 200–600 mg per day for hereditary angioedema, usually taken in divided doses.
- The form of administration is oral capsules, commonly 50 mg, 100 mg, or 200 mg.
- Danazol usually starts working within days to a few weeks, depending on the condition being treated.
- The duration of action is around 12–24 hours, so it is typically taken twice daily or in divided doses.
- Do not consume alcohol, as it may increase the risk of liver-related adverse effects and worsen tolerability.
- The most common side effects are weight gain, acne, oily skin, hirsutism, voice deepening, menstrual irregularities, nausea, and mood changes.

Latest Research Highlights
Looking for a medicine that still has a place, but only for the right patient?
That is where danazol sits in 2022–2025 evidence reviews.
It remains a niche but clinically relevant oral anti-gonadotropin for endometriosis-related pain, fibrocystic breast disease and hereditary angioedema prophylaxis.
Recent international literature continues to show effectiveness, but its role is narrower because androgenic and hepatic adverse effects can be difficult to manage.
In Australia, danazol capsules Australia are generally used cautiously, with specialist prescribing, symptom-focused follow-up and monitoring aligned with TGA safety expectations rather than high-volume PBS use.
That makes danazol research important in real practice, because response is judged case by case, not by broad population prescribing patterns.
Access can also vary across metro and rural areas.
Telehealth reviews and e-prescriptions can help continuity, although supply through major chains and online pharmacies may still be patchy.
| Evidence Area | Australian And Global Signal | Practical Takeaway |
|---|---|---|
| Endometriosis pain | Still effective in selected patients, but often not first choice because of tolerability | Use is usually specialist-led and response-based |
| Hereditary angioedema | Remains a useful prophylactic option when other therapies are unsuitable or unavailable | Can be clinically valuable in rare disease management |
| Fibrocystic breast disease | Evidence supports symptom control in selected cases | Usually short-term and monitored closely |
| TGA safety | Ongoing review focuses on androgenic and hepatic risk | Monitoring is central to safe prescribing |
| Common Safety Observation | What Patients May Notice | Why It Matters |
|---|---|---|
| Weight gain | Slow increase in body weight | May affect adherence and quality of life |
| Acne | New or worsening pimples or oily skin | Typical androgenic effect |
| Menstrual changes | Amenorrhoea, spotting or irregular periods | Can signal expected hormonal suppression |
| Voice deepening | Change in pitch that may not fully reverse | Needs prompt medical review |
| Liver enzyme concerns | Usually no symptoms at first | Supports routine liver monitoring |
Clinical Effectiveness In Australia
What does good treatment look like when danazol is used here?
In Australian practice, effectiveness is usually measured by symptom control, not by population-wide prescribing numbers.
There is no routine PBS-heavy, high-volume pattern like you would see with common chronic medicines.
That means danazol treatment Australia is normally individualised, with the prescriber checking whether pain, swelling or breast symptoms are actually improving and whether side effects are worth the trade-off.
For endometriosis, danazol for endometriosis can give meaningful pain relief, but many clinicians now try alternatives first because tolerability is often the limiting factor.
For hereditary angioedema, it can still be valuable when access to newer options is limited or unsuitable.
TGA monitored medicine principles apply in practice.
That means ongoing liver monitoring, cardiovascular risk awareness, review of adverse effects and dose reduction to the lowest effective dose whenever possible.
A patient may start on a higher dose, feel better after a few weeks, and then step down if symptom control remains stable.
| Outcome | What Clinicians Look For | Typical Review Point |
|---|---|---|
| Symptom reduction | Less pain, fewer attacks or improved breast symptoms | Early follow-up after starting |
| Dose minimisation | Reduced to the lowest effective dose | After clinical response is established |
| Discontinuation due to side effects | Stopping if androgenic or hepatic effects become troublesome | Any time adverse effects escalate |
| Monitoring intervals | Regular review of symptoms and labs | Individualised, often specialist-led |
- Most useful when: first-line hormone options are unsuitable or have failed.
- Less attractive when: acne, voice change or liver concerns are a problem.
- Best practice: reassess often and keep the dose as low as possible.
Indications And Expanded Uses
Which conditions does danazol actually cover, and where does specialist judgement come in?
The core indications are straightforward, but Australian practice still depends on diagnosis-specific dosing and informed consent.
- Endometriosis
- Used to reduce endometriosis pain by suppressing hormonal stimulation.
- Fibrocystic Breast Disease
- Used to improve breast pain, tenderness or cyclical discomfort in selected cases.
- Hereditary Angioedema Prophylaxis
- Used to help prevent attacks in patients who need ongoing prophylaxis.
Some specialist off-label use may occur where other hormone-modulating options are not suitable, but that should always follow risk review and clear counselling.
People searching for “danazol for endometriosis” or “danazol capsules Australia” are often trying to work out why a medicine can be helpful in rare cases yet still not be a first-line choice for everyone.
The answer is that benefit can be real, but so can the androgenic and hepatic burden.
Danazol is prescription only, and the dose depends on the condition being treated.
Composition And Brand Landscape
Is it a brand medicine, a generic, or both?
The active ingredient is danazol, and Cyclomen is the best-known global brand from the available data.
Generic danazol capsules exist in some markets, including 50 mg, 100 mg and 200 mg strengths.
| Product Fact | Details |
|---|---|
| INN | Danazol |
| Best-known brand | Cyclomen |
| ATC classification | G03XA01 |
| Dosage forms | Oral capsules only |
| Common strengths | 50 mg, 100 mg, 200 mg |
| Typical packaging | Blister packs or bottles of 30 to 60 capsules |
For Australian consumers, brand and supply can change over time.
That means a patient might see one listing through a pharmacy chain, another through an online pharmacy, and a different option via hospital or special-order supply.
Danazol 100 mg and danazol 200 mg are the strengths most people ask about, but local stock is still determined by current supply rather than shelf visibility.
Contraindications And Special Precautions
Before a prescriber reaches for danazol, the safety screen matters more than the brand name.
- Pregnancy: contraindicated because of risk of masculinisation and teratogenic effects.
- Lactation: contraindicated.
- Active or past thromboembolic disease: contraindicated.
- Porphyria: contraindicated.
- Androgen-dependent tumours or suspected malignancy of the breast or genitalia: contraindicated.
- Severe hepatic, renal or cardiac dysfunction: contraindicated.
- Hypersensitivity to danazol or excipients: contraindicated.
- Diabetes, hypertension, epilepsy, migraine, cardiovascular disease or a thromboembolism history: need close monitoring.
Women of childbearing potential need clear contraception advice and pregnancy avoidance counselling.
That is not a box-ticking exercise, because accidental exposure in pregnancy is a serious problem.
Daily life matters too.
If dizziness, mood change or fatigue affect concentration, driving or safety-sensitive work may need to be paused until the prescriber reviews things.
For some Aboriginal and Torres Strait Islander patients, ongoing monitoring can be harder because of distance, transport and service access.
Shared decision-making and simpler follow-up pathways can make a real difference to continuity of care.
Dosage Guidelines
How much is usually used, and for how long?
Danazol dosage is diagnosis-specific and usually taken in divided doses.
| Indication | Usual Adult Dose | Duration |
|---|---|---|
| Endometriosis | 200–800 mg/day in divided doses | 3–6 months, sometimes up to 9 months |
| Fibrocystic breast disease | 100–400 mg/day | Usually 3–6 months |
| Hereditary angioedema prophylaxis | 200–600 mg/day | Ongoing with periodic re-evaluation |
For endometriosis, treatment is often started at a higher dose for symptom control, then reduced to the lowest effective dose once the response is clear.
Children are generally not recommended because safety data are lacking.
Elderly patients need caution, with lower initial doses often considered.
Severe liver or kidney impairment is a contraindication, because accumulation and toxicity become more likely.
If a dose is missed, take it as soon as remembered unless the next dose is close.
Do not double up.
Overdose needs immediate medical attention, especially if severe nausea, vomiting or abnormal bleeding occurs.
Interaction Overview
Could another medicine be making danazol harder to use safely?
That is a very common pharmacist question, especially when the medicine comes through more than one pharmacy or via telehealth.
| Interaction Area | Why It Matters |
|---|---|
| Anticoagulants | Can alter clotting risk and needs careful review |
| Antidiabetics | Blood glucose control may need closer monitoring |
| Antihypertensives | Blood pressure management may need review |
| Other hormone-related treatments | May change hormonal response or side-effect burden |
| Liver-burdening medicines | Can add to hepatic risk |
Alcohol should be minimised because of liver risk.
There is no classic food ban, but a medication review is still wise if headaches, palpitations or nausea are an issue.
Telehealth medication reviews and My Health Record can help spot interaction risks early, which is especially useful when scripts are supplied through an online pharmacy or several different brick-and-mortar pharmacies.
Cultural Perceptions And Patient Habits
How do Australians usually approach a medicine like this?
Price sensitivity and trust in pharmacists are big factors.
Many people ask at Chemist Warehouse, Priceline or TerryWhite Chemmart first, then check online if stock is uncertain.
That pattern matters more for danazol Australia because it is not a high-demand medicine that sits on every shelf.
- Metro patients: usually have more immediate choice and faster resupply.
- Rural patients: often rely on telehealth prescription support, postal supply and better refill planning.
- Women’s health communities: commonly discuss weight change, acne and mood shifts, which can strongly affect adherence.
Hormone-related medicine can also feel personal.
For that reason, a non-judgemental explanation of why danazol is being used can improve acceptance, especially when the condition is endometriosis pain or hereditary angioedema.
In our online pharmacy, danazol is available without a prescription, with discreet delivery to Australia in 5-14 days.
Availability And Pricing Patterns
Can you actually get it, and what will it cost?
Availability can be variable because danazol is prescription-only and not always a high-demand item.
| Purchase Pathway | What It Usually Means | Affordability Note |
|---|---|---|
| PBS-subsidised supply | Lower out-of-pocket cost where a listing applies | PBS access can materially improve affordability |
| Private purchase | Full private cost paid by the patient | Price can vary by supplier and strength |
| Online pharmacy supply | Useful when local stock is uncertain | Often paired with e-prescription workflows |
| Special-order or hospital supply | Used when standard stock is limited | May improve access in patchy supply situations |
Some markets have withdrawals or limited registrations, so Australian patients may need special-order sourcing or a generic brand substitution.
Packaging is commonly 30 or 60 capsules depending on supplier.
That is why planning ahead matters, especially for rural patients or anyone with a narrow refill window.
Comparable Medicines And Preferences
What gets considered instead of danazol?
The answer depends on the condition being treated, cost, access and tolerability.
| Condition | Possible Alternatives | Why They May Be Chosen |
|---|---|---|
| Endometriosis | GnRH analogues such as leuprolide, or progestins such as medroxyprogesterone acetate | Often preferred because androgenic effects may be less troublesome |
| Fibrocystic breast disease | Tamoxifen or bromocriptine | May suit some patients better depending on symptoms and risk profile |
| Hereditary angioedema | Specialist-directed newer therapies where available | Choice depends on access and patient suitability |
Pros: oral convenience, established history, useful in selected rare indications.
Cons: androgenic side effects, liver monitoring burden, and not suitable in pregnancy.
Danazol alternatives are not just about theoretical efficacy.
In real life, the winner is often the treatment the patient can tolerate, afford and monitor safely.
Frequently Asked Questions
What is danazol used for?
It is used for endometriosis pain, fibrocystic breast disease and hereditary angioedema prophylaxis in selected patients.
Can I get danazol on the PBS?
That depends on current listings and supply arrangements, so the pharmacist and prescriber need to confirm it for your situation.
How long does it take to work?
Some people notice symptom changes within weeks, but treatment response is reviewed over time and depends on the condition.
What side effects should I watch for?
Weight gain, acne, menstrual changes, mood change, voice deepening and liver-related symptoms should be reported promptly.
Guidelines For Proper Use
Safe use starts with the small details that often get missed.
- Take danazol exactly as prescribed, usually in divided doses.
- Use contraception if pregnancy is possible.
- Do not stop or change the dose without medical advice, especially for hereditary angioedema prophylaxis.
- Seek review for jaundice, dark urine, severe abdominal pain, unusual bleeding, major mood change or voice changes.
- Keep all medicines together for review, including OTC products and supplements.
- Store at 15–25°C, away from moisture and light.
Clear counselling matters because hormonal medicines can raise worries about fertility, body changes and long-term safety.
That conversation should be straightforward, calm and specific to the patient’s diagnosis.
