What Ospolot is used for
Ospolot is used to control epilepsy. Epilepsy is a condition where you have repeated seizures or fits. There are many different types of seizures, ranging from mild to severe.
This medicine belongs to a group of medicines called sulphonamides.
These medicines are thought to work by controlling brain chemicals that send signals to nerves so that seizures do not happen.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

How to take Ospolot
Follow all directions given to you by your doctor or pharmacist carefully. It may differ from the information contained in the leaflet.
If you do not understand the instructions on the bottle, ask your doctor or pharmacist for help.
How much to take
Your doctor will tell you how many tablets you will need to take each day. This may depend on your age, your condition and whether or not you are taking any other medicines.
Your doctor may recommend that you start with a low dose of Ospolot and slowly increase the dose to the lowest amount needed to control your epilepsy.
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, Ospolot may not work as well and your problem may not improve.
How to take it
Swallow Ospolot with a glass of water.
When to take it
Take Ospolot 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 Ospolot immediately after a meal, at about the same time each day. If you take it on an empty stomach, it may cause a stomach upset.
How long to take it
Continue taking Ospolot for as long as your doctor tells you to. Ospolot helps control your condition, but does not cure it. Therefore you must take your medicine every day, even if you feel well.
Most anticonvulsant medicines take time to work, so do not be discouraged if you do not feel better straight away.
Do not stop taking Ospolot or lower the dosage, without checking with your doctor. Do not let yourself run out of medicine over the weekend or on holidays. Stopping this medicine suddenly may cause unwanted effects or make your condition worse. Your doctor will slowly reduce your dose before you can stop taking it completely.
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 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), or go to the Accident and Emergency Department at your nearest hospital, if you think that you or anyone else may have taken too much Ospolot. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Symptoms of an overdose may include:
- dizziness, light-headedness
- spinning sensation
- unsteadiness when walking
