Use systane ultra several times a day and on eyedrop antibiotic tobramycin dexameth. can drops go into your sinus affect nasal and give a bad taste? sinuses are draining due to excessive tearing from eye issue?

A doctor has provided 1 answer

Naso-Lacrymal duct: The eye fluids normally drain into the nose through the nasolacrymal duct that starts at the inner end of the eye and drains into the nose. From the nose it can drain into the throat. So any drops added into the eye can affect the nasal mucosa and be tasted by reaching the throat. It would be prudent to see a doctor for a more effective treatment for the eye issue. Wish you good health!
