Children and adolescents
Rexer should not normally be used for the treatment of children and adolescents under 18 years. This is because the safety and effectiveness of Rexer in this age group have not been established. Moreover, you should know that in patients under 18 years, there is an increased risk of adverse effects such as suicide attempts, suicidal thoughts, and hostility (mainly aggression, confrontation, and irritability) when taking this type of medicine. Nevertheless, your doctor may prescribe Rexer to patients under 18 years when he decides that it is the best for the patient. If your doctor has prescribed Rexer to a patient under 18 years and you want to discuss this decision, please go back to your doctor. You should inform your doctor if any of the above symptoms appear or worsen in patients under 18 years who are taking Rexer. Additionally, the long-term safety effects on growth, maturation, and development of cognition and behavior of Rexer in this age group are not yet known. It has also been observed that this age group, when treated with Rexer, experiences a significant increase in weight more frequently than adults.
