For a small number of medicines, there are differences in equivalent doses of oral formulations of the same medicine. This needs to be considered when switching a patient from one oral formulation to another, for example, switching from tablets or capsules to a liquid to aid administration in a patient with dysphagia or swallowing difficulties.

This Q&A contains a summary table of medicines which may require dose adjustment when switching between oral formulations, and presents information on dose adjustment.  In instances where it may not be possible to achieve a dose that is exactly the same, practical advice such as additional patient monitoring is suggested. Other concerns relating to the suitability of the formulation for the patient are discussed.
