Missed progestogen-only contraceptive pills

A progestogen-only pill (POP) containing levonorgestrel or norethisterone is considered missed if it is more than 3 hours late; see Missed progestogen-only contraceptive pills containing levonorgestrel or norethisterone: advice for patients for advice for patients.
The advice for missed POPs containing drospirenone is the same as for missed combined oral contraceptives; see Missed combined oral contraceptives and drospirenone progestogen-only pills: advice for patients for advice for patients.

Note:

NB1: Ulipristal (another type of emergency contraception) is usually not suitable in this scenario; if any hormonal contraception (excluding levonorgestrel-releasing intrauterine contraceptive devices) has been used in the past week, it may reduce the effectiveness of ulipristal. The progestogen-only pill also can’t be restarted for 5 days after ulipristal, so condoms are required for 7 days after taking ulipristal (to allow time for three consecutive pills to be taken).
