What is in this leaflet

This leaflet answers some common questions about Alprim.

It does not contain all 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 taking Alprim against the benefits expected for you.

If you have any concerns about taking this medicine, talk to your doctor or pharmacist. Keep this leaflet with your medicine.

What Alprim is used for

Alprim is used to treat infections of the urinary tract caused by bacteria.

Alprim belongs to a group of medicines called antibiotics. It works by stopping the growth of the bacteria that is causing your infection.

Alprim will not work against infections caused by viruses, such as colds or flu.

Ask your doctor if you have any questions about why Alprim has been prescribed for you.

Your doctor may have prescribed Alprim for another reason.

Alprim is available only with a doctor`s prescription.

Alprim is not recommended for use in children under 6 years of age, as the safety and effectiveness of Alprim in this age group has not been established.

    Do not stop taking Alprim, 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.

  • If you forget to take Alprim

    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 or have any questions, ask your doctor or pharmacist.

    If you take too much Alprim (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 Alprim. Do this even if there are no signs of discomfort or poisoning.

    Other side effects not listed above may also occur in some people.

    After taking Alprim


    Keep Alprim where children cannot reach it.

    A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.

    Heat and dampness can destroy some medicines.
