What Rimycin is used for

RIMYCIN is an antibiotic that is used in combination with other medicines to treat tuberculosis, also known as TB.
TB is a bacterial infection, which mainly affects the lungs, but it can also spread to other organs in the body.
RIMYCIN is also used to treat leprosy, a skin condition that has many forms.
RIMYCIN can also be used to prevent certain diseases occurring where you may be in contact with, or have had contact with, a person known to have the disease or is known to be able to pass it on to others.
Examples of such diseases are meningitis (a serious infectious disease involving inflammation of the membranes that cover the brain and spinal cord) which affects children and young adults, pneumonia, conjunctivitis and meningitis caused by Haemophilus influenzae, a bacterium in the respiratory tract.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor's prescription.

If you forget to take it

Take the dose as soon as you remember, and then go back to taking your medicine as you would normally.

If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much RIMYCIN. Do this even if there are no signs of discomfort or poisoning.

While you are using RIMYCIN

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking RIMYCIN.
Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine.
Take RIMYCIN exactly as your doctor has prescribed. Keep all of your doctor's appointments.
If you develop itching with swelling, a skin rash or have difficulty breathing, or if you turn yellow while you are taking RIMYCIN, stop taking it and tell your doctor immediately.
If you get severe diarrhoea tell your doctor or pharmacist immediately. Do this even if it occurs several weeks after you have stopped taking RIMYCIN.
Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical care. Do not take any diarrhoea medicine without first checking with your doctor.
If you get a sore white mouth or tongue while taking or soon after stopping RIMYCIN, tell your doctor.
If you get vaginal itching or discharge while taking or soon after stopping RIMYCIN, tell your doctor.
This may mean you have a fungal infection called thrush. Sometimes the use of RIMYCIN allows fungi to grow and the above symptoms to occur. This medicine does not work against fungi.
If you become pregnant or are breastfeeding while taking this medicine, tell your doctor immediately.
If you are using oral contraceptives you should change to alternative methods of birth control while you are taking RIMYCIN.
If you are about to have any blood or urine tests, tell your doctor that you are taking this medicine.
It may interfere with the results of some tests.
If you develop a new or sudden worsening of shortness of breath, possibly with a dry cough or fever that is not responding to antibiotic treatment.
These could be symptoms of lung inflammation (interstitial lung disease/pneumonitis) and can lead to serious breathing problems due to collection of fluid in the lungs and interfere with normal breathing which can lead to life threatening conditions.

Things you must not do

Do not take RIMYCIN to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or lower the dosage without checking with your doctor.
If you do not complete the full treatment as prescribed by your doctor, some 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 it may return.

Things to be careful of

Be careful driving or operating machinery until you know how RIMYCIN affects you.
