Recommendations are provided on the various indications for extemporaneous preparations and their quality assurance. The importance of pharmaceutical vehicles and problems associated with substituting one vehicle for another are discussed. The guidelines include criteria for choosing a suitable pharmaceutical vehicle and for specific aspects in terms of treatment planning. In addition, recommendations are given for managing allergic reactions to vehicles or additives.
