My son is 12 1/2 and about two months ago he started having random panic attacks. Scared me at first not knowing what they were but now are more understandable. His pediatrician started him on 10 MG Lexapro and the first few days were great but after about day five he started having more panic attacks. I understand the medicine talks a few weeks to actually start fully working but just wanted to know if anyone else experienced more panic attacks after starting Lexapro and if it caused hiccups for anyone. Thanks in advance for any help. Worried Parent.
