What Bicillin L-A is used for
Bicillin L-A is used to treat infections in different parts of the body caused by bacteria. Bicillin L-A is also used to prevent certain infections such as rheumatic fever. Bicillin L-A will not work against infections caused by viruses such as colds or flu.
Bicillin belongs to the group of penicillin antibiotics. It works by killing bacteria or preventing their growth. This particular type of Bicillin is called Bicillin L-A because it is long-acting. It is supplied in a syringe for once-only use.
Your doctor may have prescribed Bicillin L-A for another purpose. Ask your doctor if you have any questions about why Bicillin L-A has been prescribed for you.
This medicine is available only with a doctor's prescription.

How Bicillin L-A is given
Bicillin L-A is usually only given by a doctor, pharmacist or nurse. It is injected into a muscle. For adults this is usually the buttocks. With small children it may be the thigh. It must not be injected near an artery or nerve. If the injection is repeated, a new site must be chosen.
Your doctor will decide what dose and how many times you will receive Bicillin L-A. This depends on your infection and other factors, such as your weight.
Sometimes only a single dose of Bicillin L-A is needed for the treatment or prevention of certain infections.
While you are using Bicillin L-A
Things you must do
If the symptoms of your infection do not improve within a few days, or if they become worse, tell your doctor.
If you develop itching with swelling or skin rash or difficulty breathing after you have been given Bicillin L-A, contact your doctor immediately as these are symptoms of an allergic reaction.
Tell your doctor or pharmacist if you develop severe diarrhoea, even if it occurs several weeks after you have stopped receiving Bicillin L-A.
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 after you have been given Bicillin L-A, tell your doctor. Also tell your doctor if you get vaginal itching or discharge.
This may mean you have a fungal infection called thrush. Sometimes the use of Bicillin L-A allows fungi to grow and the above symptoms to occur. Bicillin L-A does not work against fungi.
If you become pregnant while you are receiving Bicillin L-A injections tell your doctor.
If you are about to start taking any new medicines, tell your doctor or pharmacist you are receiving Bicillin L-A.
