What is in this leaflet
This leaflet answers some common questions about CLARITHRO.
It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have benefits and risks. Your doctor has weighed the risks of you using CLARITHRO against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, talk to your doctor or pharmacist.
Keep this leaflet with your medicine. You may need to read it again.
What CLARITHRO is used for
CLARITHRO is used to treat certain bacterial infections, including the following:
- respiratory tract infections
- skin infections
- peptic ulcer.
CLARITHRO is also used to prevent a specific bacterial infection associated with HIV infection.
Your doctor, however, may have prescribed CLARITHRO for another purpose.
Ask your doctor if you have any questions about why CLARITHRO has been prescribed for you.
CLARITHRO is an antibiotic that belongs to the group of medicines called macrolides. These medicines work by killing or stopping the growth of bacteria which cause infections.
CLARITHRO will not work against infections caused by viruses, such as colds or flu.
CLARITHRO is available only with a doctor's prescription.
CLARITHRO to treat peptic ulcer
Peptic ulcers are associated with an infection in the intestine and stomach caused by the bacteria Helicobacter pylori (H. pylori). Nearly all patients with peptic ulcers are infected with H. pylori.
The H. pylori infection can be treated with a combination of CLARITHRO (clarithromycin), another antibiotic (amoxycillin) and another medicine called omeprazole (used to control the acidity of the stomach).
However, the best combination of tablets to treat H. pylori infection is yet to be determined. Your doctor will determine the best combination for you.
If your symptoms return, consult your doctor.
It is possible that CLARITHRO may no longer be effective in killing the H. pylori infection and a different antibiotic may be needed.

How to take it
How much to take
The dose of CLARITHRO will depend on the infection to be treated.
For respiratory tract infections and skin infections, the usual adult dose is one CLARITHRO 250 mg tablet twice a day.
For more severe infections, the dose can be increased to two CLARITHRO tablets twice a day.
Your doctor will adjust the amount or frequency of your doses according to the infection being treated and the severity of your condition.
Follow all directions given to you by your doctor and pharmacist carefully.
How to take CLARITHRO
CLARITHRO tablets should be swallowed whole with a glass of water.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take the missed dose as soon as you remember, and then go back to taking your tablets as you would normally.
Do not take a double dose to make up for the dose you missed.
If you are not sure what to do, ask your doctor or pharmacist.
How long to take it for
Keep taking CLARITHRO until you finish the pack or for as long as your doctor tells you.
If you are being treated for an infection, CLARITHRO is usually taken for one or two weeks.
Do not stop taking CLARITHRO, even if you feel better after a few days, unless advised by your doctor.
Your infection may not clear completely if you stop taking your medicine too soon.
Check with your doctor if you are not sure how long you should be taking CLARITHRO.
If you take too much CLARITHRO (overdose)
Immediately telephone your doctor, or the Poisons Information Centre (telephone 13 11 26), or go to Accident and Emergency at the nearest hospital, if you think you or anyone else may have taken too much CLARITHRO. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too much CLARITHRO, you may develop severe gastrointestinal symptoms, liver problems, or allergic reactions.

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking CLARITHRO.
