Escapelle/Postinor is designed to be used as emergency contraception and should not be used as a regular method of birth control. It is meant for occasional use, not for repeated or frequent use. Taking it too often can disrupt your hormonal balance and may cause side effects. To ensure effective and safe contraception, see your options here.
