Children and older adults
Children need an age- and weight-appropriate product. Never use adult tablets as a substitute for a paediatric formulation without professional guidance.
Storage
Store in the original packaging as directed. Liquid suspensions may have specific storage conditions and expiry after opening — always keep medicines out of reach of children.
Missed dose
If you miss a dose, follow the instructions on your prescription leaflet or ask your pharmacist. Never take two doses at once or extend treatment on your own.

If you suspect an overdose or accidental poisoning:
contact your local emergency services or the nearest hospital emergency department immediately. Do not wait for symptoms.
