Which medicines require extra care when switching between liquid and tablet/capsule formulations?

For a small number of medicines, there are differences in equivalent doses of oral formulations of the same medicine. This Q&A considers which medicines may require dose adjustment when switching between oral formulations and presents information on dose adjustment in a summary table.  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.
