As the authors note in their Introduction, the plethora of new psychopharmacological agents introduced in the last decade has led to an extensive literature on the use and proposed mechanisms of action of these drugs. However, the literature on the side effects of these medications is limited at best. Rare is the patient who does not have at least some side effects from our treatments, yet far too often the patient’s only source of information on the drug and its side effects is the Compendium of Pharmaceutical and Specialties (CPS).1 Unfortunately, more often than it should be, the CPS is also the physician’s side effect “handbook”!
The authors have attempted to bridge this gap in our psychopharmacological knowledge base with a user-friendly, spiral-bound “handbook” on managing side effects of psychotropic drugs. They have done a good job.
The 8 chapters begin with an overview of the different classes of psychoactive agents, which includes an excellent table listing all antipsychotic and antidepressant agents (generic and trade names) and the average daily dose ranges. Unfortunately, hypnotics, anxiolytics, mood stabilizers and stimulants are omitted from the tables without explanation.
Chapter 2 reviews predisposing risk factors, epidemiology and classification (e.g., predictable v. idiosyncratic, initial v. tardive) of side effects, while the bulk of the handbook — Chapter 3 — is a detailed overview of these side effects. The format of Chapter 3 is unique, with “generic” headings such “dermatological” followed by subheadings (e.g., acne, allergic rash, alopecia, etc.). Under the subheadings, prevalence, occurrence, presentation, mechanism of action, and commonly associated drugs with this specific side effect are outlined. This is a very useful presentation for mental health professionals (physicians, nurses and students), but I suspect that drug “consumers” would have difficulty navigating this section. (Would they know to look under dermatological and alopecia for “hair loss”?)
Chapter 4 is a more academic chapter on evaluating side effects, and provides a listing of the various rating scales available to measure and monitor side effects.
Chapter 5, “Management of Psycho-tropic Drug Side Effects/’ offers very practical, clinically relevant treatment guidelines. These “bedside tips” in the management of dry mouth, pruritis, incontinence, etc., is clearly lacking in most pharmacology and clinical psychiatry textbooks.
The last 3 chapters review the consequences of drug side effects (compliance, economic effects); administrative aspects (the lack of postmarketing data on side effects); and psychodynamic/psychological aspects of side effects, such as placebo effect, “catching” side effects, drug side effects, and the transference/counter-transference in the doctor-patient relationship. All good stuff! The bibliography and references are detailed and up to date.
This is a very good start as a handbook that will be of value to psychiatrists, residents, nurses and consumers. It should find its way to psychiatric inpatient units, mental health centres and mental health support organizations as an excellent reference book. I do hope the authors are working on their second edition, as new drugs such as citalopram, reboxitine, and mirtazapine are already here, and additional new drugs could soon make this useful book outdated.
Some minor editing (e.g., in one section, it should have read “pharmacodynamic” not “psychodynamic” parameters) and combining the chapters on identifying and managing side effects would be helpful in the next edition. Further, more detail on the specifics of managing side effects (the book is entitled Managing Side Effects), such as specific dosages of drugs used to treat specific side effects, would enhance this work.
