What is the most important information I should know about danazol?
You should not use this medication if you are allergic to danazol, or if you have
porphyria, or severe problems with your heart, liver, or kidney. You also should not take danazol
if you are
pregnant or
breast-feeding, or if you have abnormal vaginal bleeding that has not been
checked by a doctor.
This medication can cause
birth defects.
Do not use if you are pregnant.
Before you start taking danazol, you may need to have a pregnancy test to make sure you
are not pregnant.
Use an effective barrier form of birth control (such as a condom or diaphragm with
spermicide gel or inserts). Hormonal forms of contraception (such as birth control pills,
injections, implants, skin patches, and vaginal rings) may not be effective enough to prevent
pregnancy during your treatment.
Your medication needs may change if you have unusual stress such as a serious illness,
fever or infection, or if you have surgery or a medical emergency. Tell your doctor about any
such situation that affects you.
Call your doctor at once if you have a serious side effect such as sudden numbness or
weakness, problems with vision or speech, chest pain, sudden cough, or wheezing, swelling,
rapid weight gain, feeling short of breath, ringing in your ears, dizziness, nausea, pain behind
your eyes, stomach pain and loss of appetite, dark urine, or jaundice (yellowing of the skin or
eyes).
