Start taking this medication during your menstrual cycle to be sure you are not pregnant. Use effective birth control during your treatment. Danazol may decrease the effectiveness of hormonal contraceptives (birth control pills, patches, rings, implants, or injections), so you should not use these as your only method of birth control during your treatment. You also must use a barrier method of birth control (device that blocks sperm from entering the uterus such as a condom or a diaphragm). Ask your doctor to help you choose a method of birth control that will work for you. If you become pregnant while taking danazol, call your doctor immediately.

Danazol can increase your risk that you will develop a blood clot in your arms, legs, lungs, heart, and brain that may cause a heart attack or stroke. Tell your doctor if you have or ever had a blood clot. If you experience any of the following symptoms call your doctor immediately: warm, red, swollen, or tender leg; trouble speaking or understanding; paralysis or numbness in face, arm or leg; sudden severe headache; sudden changes in vision, blurred or blackened vision, or seeing double.

Danazol may cause liver damage with abdominal bleeding in people who take danazol for a long time. Tell your doctor if you have or have ever had liver disease.

Danazol can cause increased pressure of the fluid inside the skull. If you experience any of the following symptoms stop taking danazol and call your doctor immediately: headache, nausea, vomiting, or problems with your vision.

Keep all appointments with your doctor and the laboratory. Your doctor may order certain lab tests before and during your treatment to check your body’s response to danazol.

Talk to your doctor about the risks of taking danazol.

Inflated pharmaceutical prices are another huge factor in the steep cost of healthcare. Americans spend an average of $858 per person on prescription drugs, according to Vox. That’s about twice as much as people in Australia spend on prescriptions. It’s three times the amount paid by people in The Netherlands.

🔔 Why is this medication prescribed?

Danazol is used to treat endometriosis (a condition in which the type of tissue that lines the uterus [womb] grows in other areas of the body and causes infertility, pain before and during menstrual periods, pain during and after sexual activity, and heavy or irregular bleeding)..Danazol is also used to treat fibrocystic breast disease (swollen, tender breasts with noncancerous lumps) when other treatments are not successful. Danazol is also used to prevent attacks in people with hereditary angioedema (inherited condition that causes episodes of swelling in the hands, feet, face, airway, or intestines). Danazol is in a class of medications called androgenic hormones. It works to treat endometriosis by shrinking the displaced tissue of the uterus. It works to treat fibrocystic breast disease by blocking the release of hormones that cause the breast pain and lumps. It works to treat hereditary angioedema by increasing the amount of a natural substance in the body.

🔔 How should this medicine be used?

Danazol comes as a capsule to take by mouth. It usually is taken twice a day for endometriosis or fibrocystic breast disease, or two or three times a day for hereditary angioedema. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take danazol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Do not stop taking danazol without talking to your doctor. If you have fibrocystic breast disease, breast pain and tenderness usually improve during the first month that you take danazol and go away after 2 to 3 months of treatment; breast lumps should improve after 4 to 6 months of treatment.

🔔 Other uses for this medicine

Danazol is also sometimes used to treat idiopathic thrombocytopenic purpura (ITP; an ongoing condition that may cause easy bruising or bleeding due to an abnormally low number of platelets in the blood). Talk to your doctor about the risks of using this medication for your condition.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

🔔 What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from light and excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
