How to take it
How much to take
Your doctor will tell you how much Quinate to take.
The dose will depend on the condition being treated and your response to the treatment.
Follow all directions given to you by your doctor carefully. These directions may differ from the information contained in this leaflet.
How to take it
Swallow the tablet whole with a full glass of water.
Do not chew the tablets. Quinate has a special coating to mask the bitter taste of the tablet.
How long to take it
Continue taking Quinate for as long as your doctor tells you.
Do not stop taking it, or lower the dosage, even if you are feeling better, without first checking with your doctor.
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 it as soon as you remember, and then go back to taking your medicine as you would normally.
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 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 your nearest hospital, if you think that you or anyone else may have taken too much Quinate. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Symptoms of an overdose may include:
- tinnitus (ringing in the ears)
- Skin rash
- Intestinal cramping and Vomiting
- apprehension and confusion

Tell your doctor or pharmacist if you notice anything else that is making you feel unwell. Some people may get other side effects while taking Quinate.

After taking it
Keep your tablets in the bottle until it is time to take them. If you take the tablets out of the bottle they may not keep as well.
Keep your tablets in a cool dry place, protected from light, where the temperature stays below 30°C.
Do not store it or any other medicine in the bathroom or near a sink. Do not leave it in the car on hot days or on window sills. Heat and dampness can destroy some medicines.
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.
