HOW TO USE ZOXADON

Always take ZOXADON exactly as your doctor has instructed you. You should check with your doctor if you are unsure. If you have the impression that the effect of ZOXADON is too strong or too weak, talk to your doctor or pharmacist.

Treatment of schizophrenia

You may take ZOXADON either once daily or twice daily.

Initial adult dose: The usual dose is 2 mg per day. Your doctor may increase the dosage to 4 mg per day on the second day.

Maintenance dose: Your doctor will decide what the optimum maintenance dose is based on your response. The usual maintenance dose is 4 mg to 8 mg daily, but your doctor may increase the total dose up to 16 mg per day.

Liver and kidney impairment:
Your doctor should halve both the starting dose and the subsequent dose increments if you suffer with liver or kidney impairment.

Elderly patients:
The starting dose is usually 0,5 mg twice daily. Your doctor may increase the dose up to 1 – 2 mg twice daily.

Treatment of behavioural disturbances in patients with dementia
The usual starting dose is 0,25 mg twice daily. Your doctor may increase the dose to a maintenance dose of 0,5 mg to 1 mg twice daily.

The usual starting dose is 0,01 mg per kg once daily. The doctor may increase the dose to a maintenance dose of 0,02 – 0,04 mg per kg once daily.

If you take more ZOXADON than you should:
In the event of overdosage, consult your doctor or pharmacist. If neither is available, seek help at the nearest hospital or poison control centre.

If you forget to take ZOXADON:
If you missed a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue to take the tablet at the usual time. Do not take a double or larger dose to make up for the forgotten individual doses.

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