Hello .....
I'm another (generic) lexapro person. I have been on it for 5-months now - and 20mg doses daily. My side effects were either minimal ... or the other meds I've been on had far greater side effects than the Lexapro.
It has worked pretty well for me in reducing the sometimes very high emotional state that is created by the continued use of hormone therapy and chemotherapy.
It usually has had a calming effect on me ... giving me a greater emotional feeling of peace - so it has done what was epected.
Any side effects you may have should be temporary ... but we all react differently to meds.
Wishing you well on this med.
