Lexapro does take a month or so for it to reach it’s full potency, however you should start to see benefits before then. If you want to read more information on Lexapro, their website is at:

When you get ready to get off the Lexapro, wean yourself to the lowest dose (5mg). If you’re on 20mg, cut them in half (to get 10mg) and take those for a couple weeks, then go to the 5mg pills.

After you’ve been on the 5mg pills for a couple weeks, cut them in half and take the half-pills for a couple weeks, then take the half-pills every other day for a couple weeks, then you can stop. This will slowly withdraw the Lexapro from your system, and help eliminate the possibility of withdrawal problems.

6 weeks usually but differs from individual to individual. It’s too bad that your Dr. didn’t prescribe something that can you immediately if you have an attack or feel an attack coming on. I take Xanax for my anxiety and it works very well. However, it can be very addictive.

Four to six weeks.
