How much to take

Ask your doctor or pharmacist if you are unsure of the correct dose for you. They will tell you exactly how much to take.

Follow the instructions they give you.

If you take the wrong dose, Norfloxacin Sandoz may not work as well and your problem may not improve.

The usual dose is one tablet twice a day.

How to take it

Swallow the tablets whole with a full glass of water.

When to take it

Take your medicine at about the same time each day. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.

Take your medicine on an empty stomach, for example, 1 hour before food or 2 hours after food. Food can interfere with the absorption of this medicine.

If you need to take an antacid, multivitamins, supplements containing iron, calcium or zinc, didanosine (Videx) or sucralfate, take it at least 2 hours before or 2 hours after your dose of Norfloxacin Sandoz.

How long to take it

Continue taking your medicine until you finish the pack or for as long as your doctor tells you.

If you forget to take it

Take your dose as soon as you remember, and continue to take it as you would normally.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

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 the nearest hospital, if you think that you or anyone else may have taken too much Norfloxacin Sandoz.
