- Question
Few women use contraception perfectly (that is, exactly in accordance with the product instructions) and consistently. Pregnancy rates during typical use reflect effectiveness of a method among women who use the method incorrectly or inconsistently. Few data are available on typical use of any contraceptive method among women in the UK. Much of the data on contraceptive effectiveness used in the guideline come from clinical trials or surveys undertaken in other countries such as the USA. Large prospective cohort studies are needed to compare the contraceptive effectiveness of LARC methods with non‑LARC methods during typical use in the UK.
