you have chest pain, shortness of breath, sudden dizziness, light-headedness or numbness in the face, arm, or leg
you get severe diarrhoea, even if it happens several weeks after treatment with AZITHROMYCIN VIATRIS has been stopped.
Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical care.
you get a sore, white mouth or tongue while being given, or soon after stopping AZITHROMYCIN VIATRIS or you get vaginal itching or discharge.
These symptoms may mean you have a yeast infection called thrush. Sometimes the use of AZITHROMYCIN VIATRIS allows yeast to grow and the above symptoms to occur. AZITHROMYCIN VIATRIS does not work against yeast.

Things to be careful of

Protect your skin when you are in the sun, especially between 10 am and 3 pm. If outdoors, wear protective clothing and use a 30+ sunscreen.
AZITHROMYCIN VIATRIS may cause your skin to be much more sensitive to sunlight than it is normally. Exposure to sunlight may cause a skin rash, itching, redness, or severe sunburn.
If your skin does appear to be burning tell your doctor immediately.

Things you must not do

Do not stop having treatment with AZITHROMYCIN VIATRIS without checking with your doctor.
If you do not complete the full course prescribed by your doctor, all the organisms causing your infection may not be killed. These organisms may continue to grow and multiply so that your infection may not clear completely or may return.
Do not take any other medicines whether they require a prescription or not without first telling your doctor or consulting with a pharmacist.

Driving or using machines

Be careful driving or operating machinery until you know how AZITHROMYCIN VIATRIS affects you.
Whilst it is unlikely that you will drive or operate machinery when having AZITHROMYCIN VIATRIS, you need to be aware that AZITHROMYCIN VIATRIS may cause side effects such as dizziness. This may affect your ability to drive or operate machinery.
