Azithromycin is an antibiotic that is used to treat a range of bacterial infections. These include chest, skin and sinus infections, lyme disease and sexually transmitted infections such as chlamydia. Azithromycin is also a standby treatment for traveller’s diarrhoea, although this is off-label use.
Azithromycin is an antibiotic that belongs to the macrolide family. When you take Azithromycin, it stops bacteria from creating proteins they need to stay alive. This kills off the bacteria and gives your immune system time to clear them from your body.
Azithromycin reduces the symptoms of traveller’s diarrhoea by killing off the bacteria which may be causing it. This helps you recover from traveller’s diarrhoea faster.
Azithromycin will usually start to make you feel better after 24 hours. You should complete the 72 hour course, which is typically prescribed by a doctor, for traveller’s diarrhoea to be cleared from your system.
