Hi
I had gone through the question and understand your concern.
The common side effects of
Topiramate (topamax) are;
numbness or tingling in your arms and legs; flushing (warmth, redness, or tingly feeling); headache,
dizziness,
drowsiness, tired feeling; mood problems, confusion, feeling nervous, problems with thinking or memory; changes in your sense of taste; nausea, diarrhea, stomach pain, loss of appetite,
indigestion, weight loss; or rapid back-and-forth movements of the eyes.
While that of Lexapro are dry mouth , increased sweating , dizziness , nausea , vomiting , diarrhoea or
constipation , pain in abdomen , flu like symptoms , insomnia , decreased appetite and libido , also can cause impotency.
Hope this was of help
Let me know if you have other queries
Thank you
