Mood changes on Levonorgestrel: what to expect
Mood changes — anxiety, low mood, irritability, emotional blunting — are an under-recognised but important side-effect category for many medications. Whether Levonorgestrel (Levonorgestrel) at 1.5mg causes mood changes depends on Levonorgestrel and the indication. This page focuses on the practical pattern, what is normal and what calls for review.
Documented mood effects of Levonorgestrel
For some medications in Synthetic progestin (emergency contraception), mood changes are part of the central indication. For others, mood changes are listed in the prescribing information for Levonorgestrel as side effects in a small subset of users, sometimes appearing in the first weeks of therapy and resolving spontaneously. In emergency contraception, levonorgestrel works primarily by delaying or inhibiting ovulation when taken before the LH surge.
When mood changes need review
Mild irritability or transient low mood in the first weeks on Levonorgestrel at 1.5mg is common and often improves. Persistent low mood, new anxiety that interferes with daily life, suicidal thoughts, or any sudden severe mood change warrants prompt review with the prescriber. According to current guidelines, suicidal ideation while starting any new medication should be treated as urgent.

Can Levonorgestrel cause anxiety or depression? ▾
