Hi sir, My son is 7 years old. He's having reddish eyes with irritability and discharge comes out often, watery eyes sometimes. He was prescribed montgold levocetirizine for 3 months daily at night and eye drops pataday. He's being using this tablet for a week but still he is having reddish eyes. Will it take long to get cured as he's suffering a lot. please help me. Thank you so much.
