Will going from .5 to 10mg lexapro (escitalopram) work?

No problem: It looks like you meant to write 5mg to 10mg of Lexapro (escitalopram) (.5mg Lexapro (escitalopram) doesn't exist). Consult prescriber with dosage changes. There is no issue with increasing from 5 to 10mg of Lexapro (escitalopram) once per day. Monitor for side effects closely (racing thoughts, agitation).

Dose increase: I think you mean 5 mg going to 10 mg. Improvement means symptom reduction. You don't say if you're taking for depression or anxiety. Lexapro (escitalopram) is effective for many for both. There's a good chance you'll experience less anxiety or depression on 10 mg. But let your doctor review with you in person. Lexapro (escitalopram) requires close medical supervision. Dose of 10 - 20 mg is usual range. I hope this helps.

That's a BIG jump: so FIRST consult with your prescribing MD. SSRI's in general take a while to work their way into your system, so don't be in that big of a hurry.

Closer to therapy: The typical patient in my practice on Lexapro (escitalopram) takes at least 10 mg, which seems to be within effective therapy dose range.
