My son is 11 months old and having cold for last 5 days. Initially given Jaldos syrup. Now Doctor has advised to give Phenergan 5mg. But in website it shows this should not be used for children less than 2 years of age. Please reply and tell wat should be given at intial stage itself to treat cold so that it comes in motion. Because after 2 days running nose goes and nose block occurs which makes him to breathe with mouth.
