Dear doctors My son is 6 month old. He is having red eyes and swelling. Sometimes keep rubbing them. Some times 1 eye become red and sometimes both eyes become red and swelling and itching is there. And nose is also rubbing. I m giving currently tobastar f two drops two times. It's 3rd day today. But not see good improvement. Sometimes it's look clear eye. And then slightly red. Swelling itching. No cold and cough. No other issue. Apart of tobastar f I m giving him refresh tear drop. But symptoms are increasing slowly. Can I give histafree eye drops too with these drops. Or oral suspension like montac lc or histafree suspension. Please guide. I have attached pic of eyes.
