If a minipill is taken more than 3 hours late, or any number of minipills are missed, backup birth control is needed for 2 days.
Notes on verification
Confirmed by multiple independent clinical sources including MedlinePlus (NIH), Mayo Clinic, Cleveland Clinic, Cornell Health, and CDC guidance. Applies specifically to traditional progestin-only minipills; newer formulations (drospirenone-based) have a longer 24-hour window, but this doesn't contradict the claim as stated for standard minipills.
