Clarithromycin for infection

About clarithromycin

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

Clarithromycin is also given to get rid of Helicobacter pylori. 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.

Common side effects of clarithromycin are:

• Feeling sick.

• Being sick.

• Stomach ache.

• Farting (wind).

• Indigestion.

• Diarrhoea.

• Changes to taste and smell.

• Sore mouth.

• Headache.

You will find a full list in the manufacturer's information leaflet supplied with your medicine.

The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

If you experience any other symptoms which you think may be due to this medicine, speak with your doctor or pharmacist.

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

• If you are pregnant or breastfeeding.

• 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.

• If you have ever had an allergic reaction to a medicine.
  

• 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 or 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.

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