Pharmacokinetics in children

There is just a single study in which the pharmacokinetics of alimemazine have been investigated in children (N = 6, median age 6.8 years). The kinetic parameters from this study show wide variations between individuals (t½ = 4.4 to 18.5 hours, median 6.8 hours).

Side effects in children

Paradoxical stimulation of the central nervous system can occur in young children in particular, which can cause sleeplessness, nervousness, confusion, tachycardia, tremors and convulsions.

The complete list of all contra-indications can be found in the national Summary of Product Characteristics (SmPC) – click here

Contra-indications in children

Children younger than 2 years because of a possible link with sudden infant death syndrome.

The complete list of all warnings and precautions can be found in the national Summary of Product Characteristics (SmPC) – click here

Warnings & precautions in children

Do not use in children aged under 2 years because of the risk of sedation and respiratory depression; there is a correlation with sudden infant death syndrome. Be careful in children aged less than 6 years because of the greater risk of neuropsychiatric side effects. Be careful in children with sleep apnoea in their previous history, when sudden infant death syndrome is known in the family, when children wake up spontaneously less easily than normal and in very sick or dehydrated children, because such children have an increased incidence of dystonia.
Do not combine with deptropine.
