Patient special groups

Elderly, debilitated patients: The use of Suprastin® requires special care because in these patients antihistamines are more likely to cause side effects (dizziness, somnolence).

Patients with impaired liver function: the dose may need to be reduced due to reduced metabolism of the active ingredient in liver disease.

Patients with impaired renal function: The drug regimen and dose reduction may need to be changed because the active ingredient is mostly excreted by the kidneys.

Interaction
