Second, these drugs don't start to work for most people until 4-6 weeks, but side effects
start right away. If you were having panic attacks before taking Lexapro
, you shouldn't have expected it to work so soon. If you weren't, it's a good chance the drug was too stimulating for you at the dose you were given -- usually, psychiatrists taper you up on the drug. But they also taper you off the drug, but after only taking it for three days you shouldn't be having any withdrawal effects.
