Cetirizine is an antihistamine and it is a drug that dogs can take. The normal dose for a dog is 0.5mg/# so at 5.5kg his dose is 6mg. At 10mg I don't think he will have much side effects if at all. The most common adverse effects of cetirizine are sedation, lethargy, vomiting, drooling (hypersalivation), and lack of appetite. These are often self-limiting meaning they will go away on their own once the drug has been metabolized out of his body. I really would not worry too much about this. Hope this helps. Best wishes.
