ACCORD AZITHROMYCIN 500MG, 3 TABLETS

Azithromycin 500mg tablets are a treatment used for traveller’s diarrhoea. They contain the active ingredient azithromycin, which is an antibiotic. The antibiotic can stop the growth of bacteria that causes traveller’s diarrhoea. One tablet is taken once a day for 3 days.

Azithromycin can be taken with or without food. The tablets should be taken at the same time every day, with half a glass of water. The usual dose is one 500mg tablet, once a day, for 3 days. You may feel better within a few days of treatment but you should always finish your course of antibiotics. If you do not, your traveller’s diarrhoea might come back. If you feel worse, or do not get better when your course is finished, speak to your doctor.

If you forget your dose, take it as soon as you remember. If your next dose is almost due, do not take your missed dose. Continue treatment and take your missed dose at the end of the treatment course. This will mean your treatment will last a day longer. Never take a double dose. If you take more than you should, speak to your doctor straight away.
