Roxithromycin works best if you take it on an empty stomach.
How long to take it for

However, your doctor may prescribe roxithromycin for longer periods.
Check with your doctor if you are not sure how long to take this medicine for.
If you forget to take it
If it is almost time to take your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take it as soon as you remember, then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose that you missed.
This may increase the chance of you experiencing side effects.
If you are not sure what to do, ask your doctor or pharmacist.

If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much of this medicine.

If the symptoms of your infection do not improve within a few days, or if they become worse, tell your doctor.
If you get severe diarrhoea, tell your doctor immediately. Do this even if it occurs several weeks after roxithromycin has been stopped.
Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical attention. Do not take any diarrhoea medicine without first checking with your doctor.
If you get a sore, white mouth or tongue while taking roxithromycin or soon after stopping roxithromycin, tell your doctor. Also tell your doctor if you get vaginal itching or discharge.
This may mean you have a fungal/yeast infection called thrush. Sometimes the use of roxithromycin allows fungi/yeast to grow and the above symptoms to occur. Roxithromycin does not work against fungi/yeast.

Things you must not do
Do not take this medicine to treat any other complaints unless your doctor tells you to.
Do not give this medicine to anyone else, even if they have the same condition as you.

This medicine may cause dizziness, blurred vision and tiredness in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking roxithromycin.
