- One 300 mg tablet once a day, or;
- One 150 mg tablet twice a day, or;
- Two 150 mg tablets once a day.
However, depending on your condition and how you react to the medicine, your doctor may ask you to take a different dose.
The recommended dosage for children more than 40 kg is one 150 mg tablet twice daily. The dosage of Biaxsig given to children is dependent on the child’s weight.
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, Biaxsig may not work as well and your problem may not improve.
How to take it
Swallow the tablets whole with a glass of water.
When to take it
Biaxsig should be taken at least 15 minutes before food or on an empty stomach (i.e. more than 3 hours after a meal).
Biaxsig works best if you take it on an empty stomach.
How long to take it
For treating infections, Biaxsig is usually taken for 5 to 10 days. However, your doctor may prescribe Biaxsig for longer periods.
Continue taking the tablets until you finish the pack or until your doctor or pharmacist tells you to stop.
Ask your doctor or pharmacist if you are not sure how long to take the medicine for.
If you forget to take it
Do not try to make up for missed doses by taking more than one dose at a time. This may increase the chance of getting an unwanted side effect.
If it is almost time for your next dose, skip the dose you missed and take the next dose when you are meant to. Do not take a double dose to make up for the dose you have missed.
If there is still a long time to go before your next dose, take it as soon as you remember, and then go back to taking it as you would normally.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering when to take your medicine, ask your pharmacist for hints.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (13 11 26), or go to the Emergency Department at your nearest hospital, if you think that you or anyone else may have taken too much Biaxsig. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
While you are taking it
Things you must do
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, pharmacist or nurse immediately. Do this even if it occurs several weeks after Biaxsig has been stopped. Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical care. Do not take any diarrhoea medicine without first checking with your doctor.
If you get a sore, white mouth or tongue while taking, or soon after stopping Biaxsig, tell your doctor or pharmacist. Also, tell your doctor or pharmacist if you get vaginal itching or discharge. This may mean you have a fungal/yeast infection called thrush. Sometimes the use of Biaxsig allows fungi/yeast to grow and the above symptoms to occur. Biaxsig does not work against fungi/yeast.
Tell all the doctors, dentists and pharmacists who are treating you that you are taking Biaxsig.
If you are about to start taking any new medicine, tell your doctor and pharmacist that you are taking Biaxsig.
If you plan to have surgery that needs a general anaesthetic tell your doctor or dentist that you are taking this medicine.
If you become pregnant while you are taking Biaxsig, tell your doctor or pharmacist immediately.
Things you must not do
Do not take more than the recommended dose unless your doctor or pharmacist tells you to.
Do not give this medicine to anyone else, even if they have the same condition as you.
Do not use this medicine to treat any other complaints unless your doctor tells you to.
Do not stop taking your tablets because you are feeling better, unless advised by your doctor or pharmacist. If you do not complete the full course prescribed by your doctor, all of the bacteria causing your infection may not be killed. These bacteria may continue to grow and multiply so that your infection may not clear completely or it may return.
After taking it
If you have any queries about any aspect of your medicine, or any questions regarding the information in this leaflet, discuss them with your doctor or pharmacist.
Keep your tablets in the blister pack until it is time to take them. If you take the tablets out of the blister pack, they may not keep well.

Keep it 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.
If your doctor tells you to stop taking the tablets or the tablets have passed their expiry date, ask your pharmacist what to do with any tablets that are left over.
