Methods of Contraception and guidance for UK HCPs

Helping your patients make the right choice

With rising abortion rates, particularly among all ages 25 and above, the largest increase are amongst women aged 30. Therefore, there is a clear need to offer the most effective contraceptive methods.¹ In a quantitative survey of over 430 women and their experiences of unintended pregnancy and abortion, over half were using contraception at the time they became pregnant.² Long-acting methods can be the most effective form of contraception because they do not rely on user compliance.³

Here you will find resources to guide conversations with your patients, helping to identify which is the most suitable contraception for them.

Pill compliance is a common struggle for women¹

For every 100 women that choose to take the pill this year, nine could become pregnant due to missed-pill moments.² Long-acting methods such as intrauterine systems (IUS) offer birth control with the highest available efficacy and are one of the most effective contraceptive methods because their effectiveness is independent of user compliance.³
