This is the 1st time I have ever posted anything. My 2 1/2 year old son was prescribed Singulair in conjunction with Zyrtec to help treat allergies and eczema. He has been an absolute nightmare....moody, cranky, tired all the time. He complains of leg pain and belly pain often. I never thought it could be the medication but after reading all of these posts, I think I will take him off the medication for a while and see what happens. I just assumed it was the "terrible two's". It's so hard to judge what is best for your child when their pediatrician and other well-educated doctors are telling you that these medications are safe for your child. You trust them....especially since a young child can't really express how the medication makes him feel other than by acting out, etc. I thank all of you for these postings. It helps to have information from others who are either taking the drug themselves or are going through the same experiences with their children.
