The research conducted in public schools in Sao Paulo city, Brazil, studied the awareness and use of emergency contraception (EC) and its possible implications on the condoms use. Among the 4929 students, 55.6% had already had sex, 19.5% had got pregnant and 7.3% had had abortions. Condoms were used by 88.6% and were options for those who did not have a steady relationship. The EC was used by 30.3% after a faulty condom usage, and by the older ones, with a steady partner. It is needed to be given contraceptive alternatives to reduce the risk and provide access to other contraceptives.
