Synthetic progestin (emergency contraception)
What to do if you miss a dose of Levonorgestrel
Missing a dose of Levonorgestrel (Levonorgestrel) is common — most people will skip a dose at some point during a course. The right action depends on how long since the missed dose and whether Levonorgestrel is taken event-driven or daily at 1.5mg. The wrong action — doubling up — is not recommended.
For daily Levonorgestrel
If Levonorgestrel is taken daily for a chronic condition, take the missed dose as soon as you remember, unless it is almost time for the next scheduled dose. In that case skip the missed dose and continue normally. According to the prescribing information for Levonorgestrel, two doses should never be taken close together to "make up" for a miss.
For event-driven Levonorgestrel
If Levonorgestrel is used as needed (not on a fixed schedule), there is no "missed dose" in the conventional sense — simply take the planned dose when needed and observe the recommended gap before re-dosing. In emergency contraception, levonorgestrel works primarily by delaying or inhibiting ovulation when taken before the LH surge.
Frequently asked questions
Should I double the dose if I missed Levonorgestrel? ▾
No. Doubling doses of Levonorgestrel to compensate is not recommended at any 1.5mg strength and increases the risk of side effects without improving efficacy. Take the next scheduled dose normally.
How many missed doses are too many? ▾
Occasional missed doses of Levonorgestrel are usually inconsequential. Repeated missed doses can compromise the therapeutic effect — for chronic conditions like those treated with Synthetic progestin (emergency contraception), consistent dosing matters. If adherence is hard, discuss reminders, simpler schedules or alternative formulations with the prescriber.
