Hello. My son is 3.5 years old and weigh 14 kgs. He is suffering from heavy dry cough along with running nose. We visited the doctor and he suggested the lower medicines: Protussa 5 ml thrice a day Levolin 3.5 ml thrice a day L Montus 5 ml once a day. By the day I have started giving medicines to my kid, he has started doing vomits. Today is his third day completed with this much dose. Pls confirm if this dose is not overdose. Thanks $ Regards, Shiwank.
