I have been having otitis media with effusion since young age and i am now 23 years old, what medicine can help to relief my symptoms?

Typically recurrent otitis media can indicate a eustacian tube dysfunction. Try using hypertonic nasal saline washes daily (2 packets of salt solution to one bottle of warm filtered/purified water). Consulting an Ear, Nose, Throat (ENT) Dr for a more thorough exam may offer other options including tympanic membrane tubes or other ways to keep the middle ear drained.
