"hi, i have been on this pill for 5 years, and they have worked great, until 6 months ago when they just stopped working! i was on 20mg this is a common problem with escitalopram, and my blood pressure went far to high, also the weight gain is terrible, my doctor put me on 20mg of prozac and i now feel so much better and the weight is coming off. i just stopped taking escitalopram and went straight on to prozac with no side effects."
