What's the same
Estrace and Lexapro are used in very different patients, and the points in common are limited. The main shared element is that both meet regulatory standards for efficacy and safety and benefit from pharmacist oversight.
Key differences
Estrace belongs to Hormones and Birth Control while Lexapro belongs to Anti-Depressants. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Estrace: Estradiol binds to estrogen receptors (ERα and ERβ) in target tissues and modulates gene expression for vascular, bone, reproductive, central nervous system and metabolic functions. Lexapro: Lexapro acts by selectively inhibiting the serotonin reuptake transporter (SERT) at the synapse, increasing serotonin availability for postsynaptic receptors.
When Estrace is preferred
Estrace tablets are approved for moderate-to-severe vasomotor menopausal symptoms, prevention of post-menopausal osteoporosis (when other agents unsuitable), female hypogonadism, and as part of feminising hormone therapy.
When Lexapro is preferred
Lexapro is approved for major depressive disorder and generalised anxiety disorder in adults and adolescents 12 years and older (depression) and adults (generalised anxiety).
Frequently asked questions
Is Estrace or Lexapro better? ▾

Can I switch from Estrace to Lexapro? ▾
Switching between Estrace and Lexapro is rarely an appropriate decision since they belong to different classes and treat different conditions. The real question is usually whether the diagnosis calls for one medication or the other — which the prescriber resolves.
Do Estrace and Lexapro have the same side effects? ▾
No — they belong to different classes and have distinct side-effect profiles. Each medication has its own prescribing information.
