I haven't taken Lexapro specifically, because I don't have depression myself, but I do have ADHD, which is associated with serotonin imbalance, so I'm familiar with the effects of this general class of medication.

It doesn't change protein structures. It's a serotonin reuptake inhibitor -- the molecule is shaped enough like serotonin that it gets absorbed instead of the serotonin molecules, meaning you have a higher active concentration of serotonin in your system.

Anyway, Lexapro's a pretty typical SSRI. Watch out for drowsiness, especially in the first two months of taking it, and it may mess with your sex drive and/or how your body reacts to arousal. Be careful not to miss a dose, because the side effects of withdrawal suck.

Do note that SSRIs are indicated primarily for severe depression and may (oxymoronically) have a lesser effect on milder cases.

But for the most part, it's pretty safe. The side effects are more in the "annoyance" category than the "life-disrupting" one.
