Children and adolescents
Zispin SolTab should normally not be used for children and adolescents under 18 years because efficacy was not
demonstrated. Also, you should know that patients under 18 have an increased risk of side-effects such as suicide
attempt, suicidal thoughts and hostility (predominantly aggression, oppositional behaviour and anger) when they
take this class of medicines. Despite this, your doctor may prescribe Zispin SolTab for patients under 18 because
he/she decides that this is in their best interests. If your doctor has prescribed Zispin SolTab for a patient
under 18 and you want to discuss this, please go back to your doctor. You should inform your doctor if any of the
symptoms listed above develop or worsen when patients under 18 are taking Zispin SolTab. Also, the long-term
safety effects concerning growth, maturation and cognitive and behavioural development of Zispin SolTab in this
age group have not yet been demonstrated. In addition, significant weight gain has been observed in this age
category more often when treated with Zispin SolTab compared with adults.

behaviour in adults aged less than 25 years with psychiatric conditions who were treated with an
