Effectiveness

How Danazol Affects PatientsDanazol is a synthetic steroid derived from testosterone. It was the first drug approved by the FDA to specifically treat endometriosis, but is now largely replaced by GnRH agonists. Danazol works by stopping the pituitary gland from producing gonadotropins, and has some androgenic properties.
How Danazol works in the bodyDanazol works to suppress the activity of hormones related to the pituitary-ovarian axis. It also limits the production of estrogens in the ovaries, and binds to hormone receptors. In the treatment of endometriosis, it causes normal and ectopic endometrial tissues to become inactive and atrophic. For fibrocystic breast disease, the effect is thought to be related to suppressed estrogenic stimulation. Lastly, it increases the level of a key protein in hereditary angioedema, C1 esterase inhibitor, which helps to control the C4 component of the complement system.

Danazol for Cystic Disease of the Breast
I felt drowsy, moody, and unbalanced after taking this medication. I also felt a bit heaty and had headaches. The worst part was that I gained weight easily, even while dieting.

I've been on Danazol for 28 years and it's definitely been worth the side effects. I'm pain- and swelling-free, thanks to this medication.

I've been on this medication for two years now. My dosage has increased to 100mg twice daily, and I no longer experience any breast pain. The only side effects I've noticed are slight weight gain and flushing, but nothing too severe.

Danazol for Endometriosis
I've been taking Danazol for 10 years now due to hereditary angioedema. Without it, I end up in the hospital. There are times when I can't afford the medication, and I wish there was some sort of assistance available for people in my situation.

Danazol for Abnormally Long or Heavy Periods
I started taking this medication six months ago at the dosage of 200mg per day. Almost immediately, I experienced adverse effects such as extreme swelling in my feet and ankles, joint and muscle pain, headaches and migraines. My blood pressure also spiked suddenly and severely, resulting in dizziness; I had to discontinue use immediately. Additionally, my menstrual bleeding stopped after three months but then returned during the fourth month. In short, this medication not only failed to work as intended but also caused a host of unpleasant side effects.

Danazol for Prevention of Angioedema Attacks in Patient with Hereditary Angioedema
I had a large cyst removed before starting this treatment, which seemed to go well. However, when I started taking danazol I felt awful. Headaches and vomiting were common for me, but thankfully they subsided after a little while. Even after six months of treatment, I was still bleeding daily. My doctor has since put me on Divigel and scheduled an ultrasound.

Danazol for Endometriosis
Unfortunately, this treatment did nothing to help my endometriosis. If anything, it made the symptoms worse. I would not recommend it to anyone.
