What E-Mycin is used for
E-Mycin is used to:
- treat certain bacterial infections
- control acne, in addition to other acne treatments
- prevent infections in people with a history of rheumatic disease, congenital heart disease or other acquired valvular heart disease and who are allergic to penicillin antibiotics.
E-Mycin is an antibiotic that belongs to a group of medicines called macrolides. These medicines work by killing or stopping the growth of bacteria, which cause infections or make acne worse.
E-Mycin will not work against infections caused by viruses, such as colds or flu.
Ask your doctor if you have any questions about why E-Mycin has been prescribed for you. Your doctor may have prescribed E-Mycin for another reason.
E-Mycin is available only with a doctor's prescription.
There is no evidence that E-Mycin is addictive.

How to take E-Mycin
Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the bottle, ask your doctor or pharmacist for help.
How much to take
The usual adult dose is one E-Mycin tablet (400 mg) every six hours but this may vary from person to person.
Your doctor will tell you how many tablets you will need to take. This depends on the infection being treated and how severe it is.
For children, their doctor will work out the dose according to their age, body weight and how severe the infection is.
How to take it
Tablets: Swallow whole with a glass of water.
Mixture: Always shake the bottle well before using a metric measure to measure the correct dose.
Shaking the bottle and using a medicine measure will make sure that you get the correct dose. You can buy a medicine measure from your pharmacist.
When to take it
Space the doses of E-Mycin evenly apart and take them at about the same time each day. This will allow E-Mycin to have its best effect and also help you to remember when to take it.
E-Mycin can be taken with or without food. However, taking E-Mycin with food may help reduce the chance of a stomach upset occurring.
How long to take it for
Keep taking E-Mycin until you finish the tablets or mixture, or for as long as your doctor recommends. If you are being treated for an infection, E-Mycin is usually taken for one to two weeks. Your infection may not clear completely if you stop taking your medicine too soon.
For controlling acne, E-Mycin is normally taken for a few months.
Check with your doctor if you are not sure how long you should be taking E-Mycin.
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 the missed dose as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose you missed.
If you have any questions or are not sure what to do, ask your doctor or pharmacist.
If you take too much (overdose)
Immediately telephone your doctor, or the Poisons Information Centre (telephone 13 11 26), or go to Accident and Emergency at the nearest hospital, if you think you or anyone else may have taken too much E-Mycin.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too much E-Mycin, you may have nausea, vomiting or problems with your hearing.
While you are taking E-Mycin
Things you must do
If your baby develops irritability with feeding or has severe vomiting during treatment with E-Mycin, tell your doctor immediately. This may be a sign of a stomach disorder in the infant.
If you are taking E-Mycin for an infection and your symptoms 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 while you are taking E-Mycin, do not take any more and contact 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 E-Mycin.
Do not take any diarrhoea medicine without checking with your doctor.
Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical care.
If you get a sore, white mouth or tongue while taking or soon after stopping E-Mycin, 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 E-Mycin allows fungi to grow and the above symptoms to occur. E-Mycin does not work against fungi.
If you become pregnant while taking E-Mycin, tell your doctor.
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking E-Mycin.
Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.
If you have to have any urine tests, tell your doctor you are taking E-Mycin. E-Mycin may affect the results of some tests.
Things you must not do
Do not use E-Mycin to treat any other conditions unless your doctor tells you to.
Do not give E-Mycin to anyone else, even if they have the same condition as you.
Do not stop taking E-Mycin, even if you feel better after a few days, unless advised by your doctor. If you stop taking E-Mycin too soon, the infection may not clear completely or your symptoms may return.
If possible, your doctor will gradually reduce the amount you take each day before stopping the medicine completely.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking E-Mycin. E-Mycin treats infections and controls acne in most people, but it may have unwanted side effects in some people.
All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
Ask your doctor or pharmacist to answer any questions you may have.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
If any of the following happen, stop taking E-Mycin and tell your doctor immediately or go to Accident and Emergency at the nearest hospital:
- signs of an allergic reaction such as any type of skin rash, itching, or hives; swelling of the face, lips, tongue or other parts of the body; shortness of breath, wheezing, troubled breathing
- watery and severe diarrhoea, which may also be bloody.
The above list includes very serious side effects. You may need urgent medical attention or hospitalisation.

- severe stomach cramps
- yellowing of the eyes or skin (jaundice), feeling generally unwell and having poor appetite
- loss of hearing
- fast, irregular or pounding heart beat
- chest pain
- confusion, hallucinations
- in infants, irritability with feeding or severe vomiting

The above list includes the more common and mild side effects of E-Mycin.

- severe abdominal cramps or stomach cramps
- watery and severe diarrhoea, which may also be bloody
- fever, in combination with one or both of the above.
You may have a serious condition affecting your bowel. These are rare but serious side effects. Therefore, you may need urgent medical attention.
Do not take any medicine for diarrhoea without first checking with your doctor.
After taking E-Mycin
Keep E-Mycin where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
Keep E-Mycin tablets in a cool, dry place where the temperature stays below 30°C.
Keep E-Mycin mixture in the refrigerator but not in the freezer.
Do not use any mixture left in the bottle after 10 days.
Do not store E-Mycin or any other medicine in the bathroom or near a sink.
Do not leave E-Mycin in the car or on window sills. Heat and dampness can destroy some medicines.
