What MACRODANTIN is used for
MACRODANTIN is used to treat infections of the urinary system caused by bacteria, for example, bladder infections.
MACRODANTIN is an antibiotic which belongs to a group of medicines called nitrofurans. It works by killing or stopping the growth of the bacteria and other organisms causing these infections.
Your doctor may have prescribed MACRODANTIN for another reason. Ask your doctor if you have any questions about why MACRODANTIN has been
prescribed for you.
These medicines are only available with a doctor's prescription.

How much to take
Adults
If you already have an infection:
The usual dose is 1 capsule (either the 50 mg or 100 mg strength) four times daily.
To prevent an infection:
The usual dose is 1 capsule (either the 50 mg or 100 mg strength) taken at night.
Children
The dose for children will depend on
their body weight. The usual dose is 1.25 to 1.75 mg/kg of body weight given four times a day. Your doctor will calculate the proper dose taking into account the age and weight of the child and how severe the infection is.
When to take it
MACRODANTIN should be swallowed with or immediately after food or with a glass of milk. If taken on an empty stomach it may cause stomach upset.
How long to take it
Continue taking MACRODANTIN until you finish the bottle or until your doctor recommends.
Do not stop taking your medicine earlier than this, even if you are feeling better.
Check with your doctor if you are
not sure how long you should be taking the medicine.
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 to. Otherwise, take it as soon as you remember, then go back to taking your medicine as you would normally.

If you take too much (overdose)
Immediately telephone your doctor, or the Poisons Information Centre (telephone 13 11 26), or go to the Accident and Emergency at your nearest hospital, if you think you or anyone else may have taken too much MACRODANTIN. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention. Keep telephone numbers for these services handy. Have the
medicine or this leaflet available to give details if needed.

Things you must do
If the symptoms of your infection do not improve, or if they
become worse, tell your doctor

Things you must not do

course prescribed by your doctor, all of the bacteria causing your infection may not be killed. These bacteria may continue to grow and multiply so that your infection may not clear completely or may return.
