Pregnancy and breastfeeding:

Driving and using machinery:
ZOXADON may cause sleepiness and a lack of concentration. Do not drive or operate any machinery before you know how this medicine affects you.

Using other medicines with ZOXADON:
Always tell your healthcare professional if you are taking any other medicine. (This includes complementary or traditional medicines.)

Do not take alcohol and ZOXADON simultaneously.

Consult your doctor or pharmacist before taking other centrally acting medicines (e.g. sleeping tablets).

ZOXADON may cause levodopa and other dopamine agonists (used to treat Parkinson’s disease) to be less effective.

Chronic administration of carbamazepine and clozapine may decrease the plasma levels of ZOXADON.

Fluoxetine and paroxetine (an antidepressant medicine) may increase the plasma concentration of ZOXADON.

Tell your doctor if you are using any medication that will cause your blood pressure to fall. Concomitant use of such medication and ZOXADON may, cause very low blood pressure.


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
If you are already using an antipsychotic medicine, your doctor may gradually discontinue this treatment when switching to ZOXADON. If you are receiving a depot injection, your doctor will initiate ZOXADON treatment in place of the next scheduled injection.

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

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.
