What is the difference between ESCITALOPRAM ORAL and PAROXETINE HYDROCHLORIDE?

Can ESCITALOPRAM ORAL and PAROXETINE HYDROCHLORIDE be used for the same conditions?

Both medications are prescribed for overlapping indications including due to AbbVie Inc.’s marketing exclusivity rights. Always verify with your prescriber and the current FDA label before switching.

Which has fewer side effects, ESCITALOPRAM ORAL or PAROXETINE HYDROCHLORIDE?

Side-effect frequency varies by individual. The side-effect comparison section on this page shows FAERS-reported events for each drug side by side. FAERS is voluntary reporting, so it reflects what patients and clinicians chose to report, not absolute population risk.

Can I switch from ESCITALOPRAM ORAL to PAROXETINE HYDROCHLORIDE?

Switching medications should always be done under prescriber supervision. The "patient stories" section on this page includes accounts from people who have made the switch and what their transition felt like, but those are individual experiences, not protocols.
