Physicians' Desk Reference has been the authoritative source on prescription drugs for 67 years. Found in virtually every physician's office, pharmacy, clinic, and library, no medical reference is more current, more recognized, or more respected. Now in its 67th edition, PDR contains full, FDA-approved drug label information, including warnings and precautions, drug interactions, and hundreds of full-color pill images. Every label in PDR includes information on dosages, side effects, and safety information, such as contraindications, pregnancy ratings, and interactions with other drugs, food, and alcohol. Data on clinical trials are also included.
