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 is also 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 (an inflammation of the membranes that cover the brain and spinal cord), affecting children and young adults, and pneumonia, conjunctivitis and meningitis caused by Haemophilus influenzae, a bacterium in the respiratory tract.
This medicine is available only with a doctor's prescription.

While you are taking Rimycin

Things you must do

Take Rimycin exactly as directed or as your doctor has prescribed. If you miss doses, side effects may occur more often and may be more serious than usual.

If you develop itching with swelling or skin rash or difficulty breathing, or if you turn yellow while you are taking Rimycin do not take any more Rimycin and tell your doctor immediately.
If you get severe diarrhoea tell your doctor, pharmacist or nurse 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. Also tell your doctor if you get vaginal itching or discharge.

Things you must not do

Do not stop taking Rimycin because you feel better.
If you do not complete the full treatment 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.
