1. What Danol is and what it is used for
Danol contains a medicine called danazol. It works by
changing the way some hormones act in your body. It is
used to treat:
• Endometriosis – an illness where some of the tissues
that line the womb are found elsewhere in the body.
One way of treating this is to have an operation and
to take Danol as well. Danol can also be used on its
own, where other treatments have not worked
• Breast cysts (lumps) which may be painful, but not
malignant. Danol is used where other treatments
have not worked or when they cannot be taken
1

Taking Danol with food and drink
Do not drink alcohol while you are taking Danol. This is
because drinking alcohol while taking Danol can make you
feel sick or short of breath.

Taking other medicines
Please tell your doctor or pharmacist if you are taking or
have recently taken any other medicines. This includes
medicines you buy without a prescription, including herbal
medicines. This is because Danol can affect the way some
other medicines work. Also some medicines can affect the
way Danol works.

Pregnancy and breast-feeding
Do not take Danol if you are pregnant, might become
pregnant or think you may be pregnant. If you think you
may have become pregnant while taking Danol, stop taking
it straight away and talk to your doctor.

In particular, tell your doctor if you are taking any of the
following:
• Steroids such as testosterone, estrogen, progesterone
(including ‘the Pill’ or hormone replacement therapy known as HRT)

How much to take
The usual dose depends on your needs
and the illness being treated:
• Endometriosis: 200 to 800mg a day for three to six months
• Breast cysts: 300mg a day for three to six months
The dose for each day may be split between two and four
separate doses.
DO NOT TAKE more than 8 of the 100mg capsules or 4 of the
200mg capsules in one day.

Do not breast-feed if you are taking Danol. This is because
small amounts may pass into mothers’ milk. If you are
planning to breast-feed, talk to your doctor or pharmacist.
Ask your doctor or pharmacist for advice before taking any
medicine if you are pregnant or breast-feeding.

Danol may increase the effect of the following medicines:
• Medicines for epilepsy, fits or convulsions (anticonvulsants)
• Medicines used to thin the blood (anti-coagulants such as
warfarin)
• Anaesthetics (see ‘Operations or tests’ section below)
• Ciclosporin and tacrolimus - used to stop the rejection of
organs after a transplant. Danol can increase the levels
of these medicines in your blood and may damage your
kidneys
• Alpha calcidol (a form of vitamin D) used for vitamin
D deficiency and illnesses where there is not enough
calcium in the blood

should check with your doctor or pharmacist if you are not
sure.
Taking this medicine

• Swallow the capsules whole with a drink of water
• If you feel the effect of your medicine is too weak or too
strong, do not change the dose yourself, but ask your
doctor
• It is important that you do not become pregnant while
taking Danol. Start taking the capsules on the first day of
your period. Use reliable contraception (such as an Intra
Uterine Device or barrier method in conjunction with
contraceptive foam or jelly). The contraceptive pill should
not be used until your treatment with Danol has finished

Operations or tests
If you are due to have an operation, tell your doctor you are
taking Danol. This is because Danol can increase the effect of
some anaesthetics.
If you have to take Danol for more than six months your
doctor will arrange for an ultrasound test to check your liver.
