Did someone prescribe Elcar to anyone? The neurologist prescribed it for prophylaxis because we were born small. We've been taking it for four days and he became somewhat nervous when I rocked him, he tries to crawl on his belly like a baby, legs flailing, he bends over, cries. He used to sleep long but never cried. I think this medication is causing such a reaction in him.
