How They Work

When looking at Lexapro vs Celexa, it’s crucial to understand how these drugs work. They both belong to a class of drugs called selective serotonin reuptake inhibitors (SSRIs). SSRIs increase serotonin levels in the brain, which is believed to help regulate mood.

Similarities between Lexapro vs Celexa:

Both prevent the reuptake of serotonin by increasing levels, which improves depressive symptoms

Both have generic versions

Both have similar side effects

Both have withdrawal symptoms

Both have relatively few concerns about drug interaction with other medication 

Both are only available by prescription, but neither is classified as “controlled drugs”

Differences between Celexa and Lexapro:

Lexapro can be administered in either liquid or tablet form, but Celexa treatment only comes as pills

Side effects may differ
