Mood changes on Addyi: what to expect
Mood changes — anxiety, low mood, irritability, emotional blunting — are an under-recognised but important side-effect category for many medications. Whether Addyi (Flibanserin) at 100mg causes mood changes depends on Flibanserin and the indication. This page focuses on the practical pattern, what is normal and what calls for review.
Documented mood effects of Addyi
For some medications in Women's Sexual Health, mood changes are part of the central indication. For others, mood changes are listed in the prescribing information for Flibanserin as side effects in a small subset of users, sometimes appearing in the first weeks of therapy and resolving spontaneously. Sexual desire is modulated by complex central nervous system pathways involving serotonin (generally inhibitory) and dopamine and norepinephrine (generally excitatory).
When mood changes need review
Mild irritability or transient low mood in the first weeks on Addyi at 100mg 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.
