The desired form and style of written drug information for patients were assessed in a national survey of oral contraceptive (OC) users. These women were queried about two forms of OC information: a short insert included with dispensed drugs and a longer brochure delivered by the physician upon patient request. Longer and more detailed information, especially concerning drug dangers and directions for use, was strongly preferred. Younger and more educated women were more likely to report receiving the OC brochure and to desire more comprehensive information. Most respondents found information in both the insert and the brochure clear and useful, and felt it was important to include written information with other prescription drugs. The longer brochure was preferred over the shorter insert as a model of drug information to be included with additional drugs.
