Common Use

Danazol is a synthetic steroid derived from ethisterone. It works by suppressing the synthesis of gonadotrophic hormones, such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH), produced by the pituitary gland in both men and women. In women, this medication inhibits ovarian activity, prevents ovulation, and causes endometrial atrophy. Danazol is commonly prescribed to treat:

• Endometriosis (often associated with infertility)
• Fibrocystic breast disease
• Inherited angioedema (to prevent attacks)
• Benign breast tumors (fibrocystic breast)
• Menorrhagia (abnormally heavy or prolonged menstrual periods)
• Premenstrual syndrome
• Primary premature puberty
• Gynecomastia

Dosage and Direction

The typical recommended dose for adults is 200-800 mg daily, divided into 2-4 doses. Treatment usually begins on the first day of the menstrual cycle. For severe endometriosis, the initial dose is often 400 mg daily, which may be increased to 800 mg as directed by your doctor. Treatment typically lasts for six months. For children with premature puberty, the dosage is usually 100-400 mg daily.

Precautions

Exercise caution if you have diabetes mellitus, epilepsy, or migraines. While taking Danazol, use reliable non-hormonal contraception (e.g., condoms or diaphragms with spermicide), as hormonal contraceptives may be less effective. Dose adjustments may be necessary for diabetic patients. Always follow your doctor's instructions and avoid exceeding the recommended dose. Women may need to start Danazol during their menstrual period. This medication may affect the results of certain medical tests, so inform your healthcare provider if you are taking it. Do not start or stop Danazol without your doctor's approval, and continue taking it even if you do not see immediate improvements. If symptoms persist after two months, consult your doctor.

Contraindications

Danazol should not be used by individuals with:

• Hypersensitivity to Danazol or its components
• Pregnancy or breastfeeding
• Porphyria (increased liver transaminase activity)
• Liver or kidney failure
• Chronic heart failure
• Thromboembolism
• Androgen-producing tumors
• Vaginal bleeding of unknown origin

Side Effects

Common side effects include:

• Allergic reactions (hives, rash, facial swelling, difficulty breathing)
• Sudden numbness or weakness
• Angina, rapid breathing, or wheezing
• Fast heart rate or sudden vision, speech, or balance problems
• Confusion, swelling, shortness of breath, or rapid weight gain
• Headache, vision issues, ringing in the ears, or dizziness
• Nausea, loss of appetite, dark urine, or jaundice
• Stomach pain or pain behind the eyes

Drug Interactions

Danazol may interact with other medications, including:

• Increase the effects of anticoagulants (e.g., coumarin derivatives), raising the risk of bleeding
• Decrease the effectiveness of insulin and oral hypoglycemic drugs, affecting carbohydrate metabolism and increasing blood sugar levels
• Inhibit the metabolism of carbamazepine, increasing its blood levels
• Increase blood concentrations of cyclosporine and tacrolimus, raising the risk of nephrotoxicity
• Increase serum levels of glucagon

Missed Dose

If you miss a dose, take it as soon as you remember. If it's almost time for your next dose, skip the missed dose and resume your regular schedule. Do not take a double dose to make up for the missed one.

Overdose

An overdose of Danazol is unlikely to cause life-threatening symptoms. Common effects of overdose may include weight gain, menstrual irregularities, increased acne or facial hair growth, and breast changes.

Storage

Store Danazol at room temperature (20-25°C or 68-77°F). Keep it away from moisture, heat, and sunlight. Avoid storing it in the bathroom or any area accessible to children.
