The objective of this book is to provide health workers with easily accessible information on important aspects of the medicines commonly used at primary care level in Zimbabwe. Medicines are a crucial part of the management of most of our patients, yet many medicines are potentially dangerous if not used correctly (by either prescriber or patient). It is important to have up-to-date information not only on the indications for, and the dose of a particular medicine, but also the contra-indications and reasons for special care, possible side effects and interactions with other medicine or medicines. The patient must also have information on how to use the preparation, what side effects may occur, and when to return for help.
