I was given 10mg of Lexapro but was worried about taking it so I cut the pill in 1/2 to lessen the potential side effects. I'm on Day 2 and it feels like my anxiety is worse. The first day had the chills real bad. Doctor also gave me clozapam for emergency if needed. I called him with my issues and he told me to stop taking it but did not give me a replacement is this normal. Should I stop taking it or give it more time?
