I have perenial allergic rhinitis. It gets worsen in rainy season with apperance of allergic conjuctivitis symptoms (redness, itching, swelling on rubbing, feeling of somethoing in the eyes). I am already taking Fexofenadine+Montelukast. What could be the reason that fexofenadine is not able to control eye symptoms. How much relief can be expected from Phenylephrine+Naphazoline eye drops? Is it advised to take antihistamine eye drops (+chlorpheniramine) on consulatation. At what stage, should I consider to take olopatadine drops after consulting opthalmologist. Please answer my queries. Thank you very much.
