What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.


Cyclomen (Danazol) is a synthetic steroid derived from ethisterone and is classified as a pituitary gonadotropin inhibitor. It is used to treat endometriosis, a condition causing infertility and pelvic pain, by managing tissue growth outside the uterus. In addition, it may help ease pain and discomfort resulting from benign fibrocystic breast disease and prevent hereditary angioedema attacks. The drug works by suppressing the production of certain hormones in the body, such as gonadotropins.

Side Effects

Cyclomen may cause various side effects. Common Danazol side effects include acne, facial puffiness, a mild growth of body hair, and a decrease in breast size. Other common effects include weight gain, a deeper voice, and oilier skin or hair.

The medication may also cause side effects linked to reduced estrogen levels, such as hot flashes, sweating, or vaginal issues like itching, dryness, or minor bleeding. Some people have mentioned feeling emotionally shaky or more nervous while on this drug.

If you notice severe side effects, seek medical help right away. Ongoing headaches or stomach pain could be a sign of problems with the nervous system or digestive tract, such as pancreatitis. In rare cases, individuals taking Danazol may experience pneumonia or severe skin irritation. Another concerning risk is liver damage, which could cause symptoms like a loss of appetite, skin or eye yellowing, and unusually dark pee. If any serious side effects occur, reach out to a healthcare professional immediately.
