5. What should I know during treatment with Zithromax IV?
Things you should do
Tell any doctor or nurse if:
the symptoms of your infection do not improve within a few days, or if they become
worse
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 Zithromax
IV 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 Zithromax
IV
you get vaginal itching or discharge.
This may mean you have a yeast infection called thrush. Sometimes the use of Zithromax
IV allows yeast to grow and the above symptoms to occur. Zithromax IV does not work
against yeast.
you realise that you are pregnant while being given Zithromax IV
during treatment with Zithromax IV your baby develops irritability with feeding or
starts vomiting.
This may be a sign of a stomach disorder in the infant.
If you are about to start any new medicines, tell your doctor and pharmacist that
you are being given Zithromax.
Tell all doctors, dentists and pharmacists who are treating you that you are being
given Zithromax.
Things you should not do
Do not take any other medicines whether they require a prescription or not without
first telling your doctor or consulting with a pharmacist.
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.
Zithromax IV 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 Zithromax IV 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.
Driving or using machines
Be careful driving or operating machinery until you know how Zithromax IV affects
you. Whilst it is unlikely that you will drive or operate machinery when having Zithromax
IV, you need to be aware that Zithromax IV may cause side effects such as dizziness.
This may affect your ability to drive or operate machinery.
Drinking alcohol
No information is available.
Looking after your medicine

The hospital staff will dispose of any leftover Zithromax IV.
6. Are there any side effects?
Tell your doctor or nurse as soon as possible if you do not feel well while you are
having treatment with Zithromax IV.
Zithromax IV is effective against certain serious infections for most people but it
may have unwanted side effects in some.
All medicines can have side effects. If you do experience any side effects, most of
them are minor and temporary. However, some side effects may need medical attention.
See the information below and, if you need to, ask your doctor or pharmacist if you
have any further questions about side effects.

Tell your doctor, nurse or pharmacist if you notice anything else that may be making
you feel unwell.

Some of these side effects (for example certain liver conditions, and blood abnormalities)
can only be found when your doctor does tests from time to time to check your progress.
After finishing it
Tell your doctor immediately if you notice any of the following side effects, particularly
if they occur several weeks after stopping treatment with Zithromax IV.
Severe abdominal cramps or stomach cramps
Watery and severe diarrhoea, which may also be bloody
Fever in combination with one or both of the above.
Zithromax IV can cause some bacteria, which are normally present in the bowel and
normally harmless, to multiply and therefore cause the above symptoms. You may need
urgent medical attention. However, this side effect is rare.
Do not take any medicine for this diarrhoea without first checking with your doctor.
Ask your doctor or pharmacist if you don't understand anything in these lists.
Do not be alarmed by the lists of possible side effects. You may not experience any
of them.
