Cetrizine Syrup is given to children to treat various symptoms such as watery eyes, runny nose, sneezing, and itching associated with allergic conditions like hay fever, urticaria (hives), conjunctivitis (red, itchy eye), and common cold. Give this medicine to your child orally with or without food in the dose, time, and way prescribed by your child’s doctor. It could either be prescribed alone or in combination with other medicines. The allergic symptoms may subside after your child has taken the initial few doses of Cetrizine Syrup. In case of serious allergic conditions, your child may have to continue taking the medicine for a week or two. If your child vomits within 30 minutes of taking this medicine, repeat the same dose after your child feels better. But, refrain from doing so if it is already time for the next dose.
