How Plan B affects libido and sex drive
Libido and sex drive are commonly affected by medications, sometimes intentionally (e.g. ED therapies) and sometimes as an unwelcome side effect. Plan B (Levonorgestrel) may or may not affect libido depending on Levonorgestrel; this page outlines what is documented at 1.5mg and what users typically report.
Documented effects of Plan B on libido
Some medications in Hormones and Birth Control are designed specifically to affect sexual function; for those, libido changes are expected and central to the indication. Others have libido changes as side effects of altered hormones, mood, energy or autonomic function. According to the prescribing information for Levonorgestrel, the documented frequency varies and is listed in the side-effect profile.
Managing libido changes
For unwanted libido suppression, the right response often depends on whether the issue is the medication itself, the underlying condition, fatigue, or relationship factors. Plan B's primary mechanism is delaying or preventing ovulation when taken before the LH surge. A dose review, a switch within the same class, or addressing other contributors are all reasonable strategies and should be discussed with the prescriber rather than self-managed by stopping Plan B at 1.5mg.
Frequently asked questions
Does Plan B lower libido? ▾
Some users on Plan B report reduced libido, some report no change, and a few — particularly on indications targeting sexual function — report improvement. Whether this happens depends on Levonorgestrel and individual factors. The prescriber can review options if libido changes are persistent or distressing.
Can libido recover after stopping Plan B? ▾
For most users, libido changes attributable to Plan B resolve within weeks of stopping the medication, though the timeline varies by active ingredient and individual. Persistent changes after stopping warrant medical evaluation, as the underlying condition may be the contributing factor.
