Clarithromycin is a type of antibiotic used to treat bacterial infections such as respiratory infections, זיהומים חיידקיים באוזניים and skin infections.

Clarithromycin is also given to get rid of הליקובקטר פילורי. This is the bacterium believed to cause stomach ulcers. If you are prescribed it for this reason, you will also be prescribed other medicines to take alongside it.

It works by stopping the bacteria causing the infection from multiplying.

Clarithromycin can be taken by adults and children.

Some medicines are not suitable for people with certain conditions. Before starting clarithromycin it is important that your doctor or pharmacist knows:

  • אם את בהריון או מניקה.

  • If you have any problems with the way your liver works or the way your kidneys work.

  • If you know you have an unusual heart rhythm.

  • If you have a muscle disorder called myasthenia gravis.

  • If you are taking any other medicines. In particular, if you are taking a 'statin' medicine for high cholesterol or colchicine for gout as well as herbal and complementary medicines.

  • אם אי פעם הייתה לך תגובה אלרגית לתרופה.

  • Read the leaflet in the pack before starting clarithromycin. It explains how to take it and lists possible side effects.

  • Take exactly as your doctor tells you to and always check the label for the correct dose.

    • It is usually taken twice a day, in the morning and evening.

  • If you’re given a modified-release (XL) tablet, you only need to take one dose a day as it releases the medicine slowly throughout the day.

  • Standard tablets, liquid, and sachets can be taken before or after food. Modified-release (XL) tablets should be taken after food. Swallow whole, don’t chew or break them.

  • When clarithromycin is prescribed for a child, the dose will depend upon the child's weight. Make sure you read the label carefully so that you measure out the correct amount of medicine.

  • If you have been given clarithromycin sachets to take, open the sachet and mix the granules into a small glass of water before taking.

  • If you forget to take a dose, take one as soon as you remember. Do not take two doses at the same time to make up for a forgotten one.

  • Treatment usually lasts 5-14 days. Keep taking the antibiotic until you finish the course, even if you feel better, unless your doctor says otherwise. This helps stop the infection from coming back.

  • Some people develop thrush (oral או vaginal) after taking a course of antibiotics. If this happens to you, speak with your doctor or pharmacist for advice about how to treat it.

  • This antibiotic may stop the oral typhoid vaccine from working. If you are having any vaccinations, make sure the person treating you knows that you are taking this medicine.

  • If you are taking a 'statin' medicine for high cholesterol your doctor may advise you to stop taking the statin whilst being treated with clarithromycin. Ask your doctor or pharmacist if you are unsure.

  • Clarithromycin usually doesn’t affect the contraceptive pill, but diarrhoea, vomiting, or breakthrough bleeding may reduce its effectiveness. Ask your doctor or pharmacist for advice if this happens.

  • If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking clarithromycin.

  • If you buy any medicines, check with a pharmacist that they are suitable to take with this antibiotic.

  • If you still feel unwell after completing your course of the antibiotic, make another appointment to see your doctor.

  • שמור את כל התרופות מחוץ להישג ידם וראייתם של ילדים.

  • יש לאחסן במקום קריר ויבש, הרחק מחום ואור ישיר.

  • If you have been given liquid medicine, it will have been made up by the pharmacy and it lasts for a limited number of days only. Check the expiry date on the bottle and do not use it after this date.
