What is in this leaflet
This leaflet answers some common questions about Megace. It does not contain all of the available information. It does not take the place of talking with your doctor or pharmacist.
You should read this leaflet carefully before starting Megace.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.

What Megace is used for
Megace contains megestrol acetate a synthetic steroid which is similar to the naturally occurring hormone progesterone. Megestrol acetate competes with naturally occurring hormones for receptor sites in breast tissue, in this way preventing the naturally occurring hormones from stimulating breast cancer cells.
Megace is used to treat the symptoms of breast cancer.

How to take it
How much to take
Your doctor or pharmacist will tell you how many Megace tablets you will need to take each day. Usually patients with breast cancer take 160mg (four 40mg tablets or one 160mg tablet each day).
How to take it
Swallow Megace with a glass of water.
When to take it
Take Megace tablets at about the same time each day.
Taking your tablet(s) at the same time each day will have the best effect. It will also help you to remember when to take the tablet(s).
It doesn't matter if you take Megace before or after food.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant too.
Otherwise take it as soon as you remember, and then go back to taking it as you would normally.
Do not take a double dose to make up for the dose you missed.
How long to take it
Megace is taken continuously (every day) and your doctor will tell you when to stop taking it.
If you take too much (Overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) or go Accident and Emergency at the nearest hospital if you think that you or anyone one else may have taken too much Megace. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.

Things you must do
If you become pregnant while taking Megace, tell your doctor immediately.
If you are about to be started on any new medicine, tell your doctor or pharmacist that you are taking Megace.
Things you must not do
Do not give Megace to anyone else, even if they have the same condition as you.
Do not take this medicine for any other complaints unless your doctor tells you to.

Things to be careful of

Megace will help most people with breast cancer but it may have unwanted side effects in a few people. All medicines can have side effects, sometimes they are serious, most of the time they are not.
Tell your doctor or pharmacist if you notice any of the following and they worry you:
Weight gain (this is a frequent side effect of Megace), nausea, vomiting, and fluid retention. In women vaginal bleeding may occur while taking, or after stopping taking Megace. These are the more common side effects of Megace.
Shortness of breath, hot flushes, mood changes, unusual hair loss or thinning, rash, pain and/or swelling at the wrists, high blood pressure, high levels of sugar in the blood (hyperglycemia) and moon face appearance may also occur very rarely.
If any of the following happen, tell your doctor immediately, or go to Accident and Emergency at your nearest hospital:
Swelling and redness along a vein which is extremely tender when touched; difficulty breathing with swelling of legs or feet due to fluid build up; sudden collapse.
These are very serious side effects. You may need urgent medical attention.
Some patients have experienced adrenal insufficiency after stopping taking Megace. If this happens you may feel weak, tired, loose weight and feel a bit dizzy from time to time. If this happens contact your doctor immediately.
Other side effects not listed above may occur in some patients.
