Thank you for your reply. Do you know where I might find researched/studied evidence of effects of Anitihisimes like Zyrtec on Children from "credible" organizations. I am looking for some data to back up what some people state in this community board about immune system suppression and detrimental effects of Zyrtec. When I researched it through traditional websites(Google), I only came up with the general side effects listed along with the prescription. I have some members of my family who are of the midset that Doctors went to school for a long time to learn how to treat illness and thus are always correct in their treatment suggestions. I am looking for some tangible validation of my thoughts and belief that natural remedies are preferable. I appreciate any response.
