What Rifadin is used for

Rifadin 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.
Rifadin is also used to treat leprosy, a skin condition that has many forms.
Rifadin 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.

Rifadin is diluted and given by intravenous infusion.
Rifadin must only be given by a doctor or nurse.
Your doctor will decide what dose and for how long you will receive Rifadin.

While you are being given it

Things you must do

If you develop itching with swelling or skin rash or difficulty breathing, or if you turn yellow while you are receiving Rifadin do not receive any more Rifadin 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 Rifadin has been stopped.

medical care. Do not take any diarrhoea medicine without first checking with your doctor.
If you get a sore white mouth or tongue while being treated with or soon after stopping Rifadin, tell your doctor. Also tell your doctor if you get vaginal itching or discharge.
