I am noticing some zapping on the left backside of my head today. Is this normal?
Normal, no, but it is a known side=effect which should diminish over the next week or two.
Also , would it hurt to take ibuprofen very occasionally while on Lexapro?
No, however, acetaminophen would be better. SSRIs slightly thin the blood, so it's best to limit the amount of anticoagulant pain killers you take.
And can someone tell me about taking Buspar vs Lexapro? Which is better and why?
Lexapro. Buspar is one of a number of psych meds that works well for a few and not at all for most. It is rarely effective for anything other than GAD. However, it may increase the effectiveness of SSRIs, restore the function of those that has stopped working, and can reduce some of their side-effects, particularly sexual dysfunction.
