Proprietary or generic formulation

Lithium is one of the few psychotropic drugs where this matters pharmacologically, as the same dose of different preparations may produce very different levels in the patient, so the prescriber must specify and stick to a particular one. This consideration does not apply to most other drugs, so generic prescribing to reduce costs is officially encouraged. However, generic prescribing has the disadvantage that different formats (size, shape, colour, and taste) of tablets containing the same dose of the same drug are available, causing patients potentially to be alarmed if the appearance of their medication changes when a fresh supply is dispensed.
