For some medications in Estrogen (weak), mood changes are part of the central indication. For others, mood changes are listed in the prescribing information for Estriol as side effects in a small subset of users, sometimes appearing in the first weeks of therapy and resolving spontaneously. Estriol binds estrogen receptors but with shorter receptor occupancy and weaker activation than estradiol, producing a 'weak' estrogenic effect.
When mood changes need review

Persistent low mood, new anxiety that interferes with daily life, suicidal thoughts, or any sudden severe mood change warrants prompt review with the prescriber.
