4. How do I use ERYC capsules?

How much to take

  • Your doctor or pharmacist will tell you how many capsules you will need to take each day. This depends on your condition and whether or not you are taking any other medicines.
  • For treating most infections, the usual adult dose of ERYC capsules is one 250 mg capsule four times a day (every 6 hours) or two 250 mg capsules twice a day (every 12 hours).
  • For the long-term prevention of streptococcal infections in persons with a history of rheumatic heart disease and an allergy to penicillin, the usual dose is one 250 mg capsule twice a day.
  • Swallow the capsules whole with a full glass of water.
  • Do not chew or crush the capsule.
  • Your doctor may ask you to take a different dose, depending on your condition and how you react to the medicine.
  • For treating infections, this medicine is usually taken for one to two weeks. However, your doctor may prescribe it for longer periods.
  • Keep taking this medicine for the full time of treatment, even if you begin to feel better after a few days.
  • If you do not complete the full course prescribed by your doctor, the infection may not clear up completely or your symptoms may return.
  • Follow the instructions provided when ERYC capsules were prescribed, including the number of days it should be taken.

When to take ERYC capsules

  • Take your medicine on an empty stomach, for example one hour before food or two hours after food.
  • Food can interfere with the absorption of this medicine.

If you forget to use ERYC capsules

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 it 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.

This may increase the chance of you getting an unwanted side effect.

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 many ERYC capsules

If you think that you have taken too many ERYC capsules, you may need urgent medical attention.

You should immediately:

  • phone the Poisons Information Centre
    (by calling 13 11 26), or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

If you take too many ERYC capsules you may feel sick (nauseous) or vomit, experience diarrhoea or hearing problems. Other effects may include those listed in the Serious Side Effects section.

5. What should I know while using ERYC capsules?

Things you should do

Call your doctor straight away if you:

  • are taking ERYC capsules for an infection and your symptoms do not improve within a few days, or if they become worse.
  • get severe diarrhoea. Do this even if it occurs several weeks after ERYC capsules have been stopped.
    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.
  • get a sore, white mouth or tongue while taking or soon after stopping ERYC capsules.
  • get vaginal itching or discharge.
    This may mean you have a fungal infection called thrush. Sometimes the use of ERYC capsules allows fungi to grow and the above symptoms to occur. ERYC capsules do not work against fungi.

Remind any doctor, dentist or pharmacist you visit that you are using ERYC capsules.

If you become pregnant while taking this medicine, tell your doctor immediately.

If you have to have any blood or urine tests, tell your doctor you are taking this medicine. It may interfere with the results of some tests.

  • 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 because you are feeling better, unless advised by your doctor.
  • If you do not complete the full course prescribed by your doctor, all 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.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how ERYC capsules affect you.

This medicine generally does not cause any problems with your ability to drive a car or operate machinery. However, as with many other medicines, it may cause dizziness in some people. If this occurs do not drive, operate machinery or do anything else that could be dangerous.

  • in the bathroom or near a sink, or
  • in the car or on windowsills.

Keep it 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.
