If you’re more than 12 hours late taking a pill, it counts as a missed dose. What you need to do next depends on the color pill you missed.
If you forget to take a gray, light blue or blue pill, take the one you missed, and then take the next pill at the normal time and continue. You should not need to use any extra contraception.
If you forget to take two gray or light blue pills (week one or week two of your pill cycle), take two of the pills you missed immediately, and the next two pills in your pack the next day. Then take the rest of your pill pack as normal. You will need to use a condom (or another barrier birth control method) for the next 7 days.
Start a new pack if you miss three or more gray or light blue pills in a row, or two or more blue pills in a row (and use a condom for a week when having sex).
If you miss one or more Tri-Sprintec white pills, you don’t need to do anything other than discard the pills you have missed, and continue as normal the next day. You won’t need any extra contraceptive cover if this happens.
