Abstract

This study describes the purchasers' profile and characterizes the pattern of use of emergency oral contraception among pharmacy users. The study was carried out in 455 Portuguese pharmacies. A cross-sectional study was undertaken in which pharmacists selected the first six purchasers of emergency oral contraception between May and June of 2006. Only user-purchasers were eligible to answer the questions about emergency oral contraception use. Participants completed a questionnaire on sociodemographic data and variables concerning contraceptive methods (including the emergency oral contraceptive acquired, the source of information about the availability of this emergency contraceptive method, prior use of emergency oral contraception, the frequency of use in the current cycle, the frequency of use in the preceding year, the time elapsed between unprotected sexual intercourse and the acquisition of emergency oral contraception, the reason for use and the regular method of contraception used). Although these drugs are available outside pharmacies--in some shops and supermarkets--their pattern of use was only assessed among pharmacy users.

Levonorgestrel-only contraceptives represented 96.1% of the emergency oral contraception acquired. User-purchasers aged between 18 and 30 represented 65.2% and 42.3% had attended secondary school. The majority of them (79.5%) were using a regular method of contraception and 62.6% were first-time users of emergency oral contraception. In 59.0% of the situations the reason for use was failure of the contraceptive used. Emergency oral contraception was used correctly by 96.9% of user-purchasers.
