Lexapro and Tamiflu 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
Lexapro belongs to Anti-Depressants while Tamiflu belongs to Antiviral Medications. 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
Lexapro: Lexapro acts by selectively inhibiting the serotonin reuptake transporter (SERT) at the synapse, increasing serotonin availability for postsynaptic receptors. Tamiflu: Oseltamivir is a prodrug rapidly hydrolysed by hepatic esterases to the active metabolite oseltamivir carboxylate, which selectively inhibits the neuraminidase enzyme on the surface of influenza A and B viruses.
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).
When Tamiflu is preferred
Tamiflu is approved in adults and children for the treatment of acute uncomplicated influenza A and B when started within 48 hours of symptom onset, and for post-exposure prophylaxis of influenza A and B in patients aged 1 year and older.
Frequently asked questions
Is Lexapro or Tamiflu better? ▾

Can I switch from Lexapro to Tamiflu? ▾
Switching between Lexapro and Tamiflu 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.

No — they belong to different classes and have distinct side-effect profiles. Each medication has its own prescribing information.
