Your doctor may have prescribed SERONIA for another reason. Ask your doctor if you have any questions about why SERONIA has been prescribed for you.
SERONIA is not recommended for use in children as there have been no studies of its effects in children.
SERONIA is available only with a doctor's prescription.

How to take it
How much to take
Your doctor will decide what dose of SERONIA you should take and how long you need to take it.
The total daily dose is slowly increased depending on your condition. The usual dose may be between 150 mg and 800 mg a day. Some people may need a different dose. Your dose will depend on your response.
If you are elderly, or have liver problems, your doctor will adjust your dose to suit you.
Follow all directions given to you by your doctor and pharmacist carefully.
How to take SERONIA
Swallow the tablets with a glass of water. Do not split, chew, or crush the tablets.
SERONIA is taken twice a day.
If you forget to take it
If it is almost time for your next dose (within 6 hours), 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.
Ask your doctor or pharmacist if you are not sure what to do.
If you take too much (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 SERONIA.

Be careful when getting up from a sitting or lying position if it makes you feel light-headed. Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure.

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking SERONIA. Like all other medicines, SERONIA may have unwanted side effects in some people.
