Pataday (Olopatadine) is an antihistamine drop used for eye allergies, which can sometimes worsen dryness. Since your main issue now is dry eyes, you should switch to over-the-counter lubricating eye drops (artificial tears). I highly recommend choosing preservative-free artificial tears, as they are gentler on the eyes and can be used safely multiple times a day. If your dryness is severe, you can also use a lubricating eye gel at bedtime. Please consult an eye specialist (ophthalmologist or optometrist) if your symptoms persist, as you may need prescription treatments or a formal dry eye evaluation.
