Yes, like Mary said..it has to build up in your system again. MOST people see results in 2-4 weeks, but it could take as long as 4-6 weeks. Because you have taken it before, and recently...it may reach therapeutic levels a tad faster. That is also a pretty low dose, is that what you were taking before? Quite possibly, after a week or so...your doc may increase your dosage.
Hope you are feeling better soon....remember to never abruptly stop taking ANY med without first speaking to your doc. I know when you get ill....you don't always think about it....but you could have saved yourself some grief, that's for sure. I'm feeling for ya!
Take Care!
I was weaned off of Lexapro and just started taking it again. Lexapro is an antidepressant like Zoloft. My doctor said it could take anywhere from 2 to 4 weeks; just as if you were starting with the medication it can take a while to reach it's full potential.
Good luck,
Mary
