Pepcid 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
Pepcid belongs to Gastrointestinal Medications 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
Pepcid: Famotidine reversibly and competitively blocks histamine H2 receptors on gastric parietal cells, reducing both basal and stimulated gastric acid secretion. Lexapro: Lexapro acts by selectively inhibiting the serotonin reuptake transporter (SERT) at the synapse, increasing serotonin availability for postsynaptic receptors.
When Pepcid is preferred
Pepcid is approved in adults and children for short-term treatment of active duodenal and gastric ulcer, maintenance therapy of duodenal ulcer, gastro-oesophageal reflux disease, Zollinger-Ellison syndrome and other hypersecretory conditions.
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

Can I switch from Pepcid to Lexapro? ▾
Switching between Pepcid 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.

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