Danazol is a synthetic androgen (male sex hormone.) It disrupts the action of the pituitary gland by suppressing the output of some hormones which causes the reduction of estrogen, halts menses and promotes the growth of facial hair and acne. Danazol is considered a second line treatment. The response rate has been about 30%. (Ref 1).

If you miss a dose of Myambutol , take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Store at room temperature away from sunlight and moisture.
