This handy, portable book provides information on potential adverse effects when prescribing two or more drugs for simultaneous use, organised by drug class in a convenient, user-friendly format. Interactions that are likely to give rise to life-threatening conditions and which must therefore be completely avoided are clearly highlighted. Less threatening, but nonetheless important, interactions necessitating practical measures such as frequent monitoring and advice to patients are also detailed. Presented in tabular form for ease of reference, the book also provides a brief summary of the mechanism underlying a particular interaction, alternative drugs lacking the same reactions that may be considered, and instructions for monitoring patients when adverse affects occur. This book is an essential companion for the physician, nurse prescriber and pharmacist in the clinical setting and an invaluable reference for medical students. Portable guide covering all major drug groups At-a-glance tabular format Use of complex pharmacological terminology minimised for the non-specialist All advice supported by appropriate evidence Also includes potential interactions with over the counter medications, herbal remedies, dietary supplements, food, and alcohol
