Phenylephrine
"This medication has been a life saver for me in getting my ears to drain.  I suffer from year round allergies and have been diagnosed with eustachian tube disfunction.  This is the only medication that works to keep my ears drained so I don't get an ear infection. I only take 10 mg. total daily broken into 2- 5 mg. doses.  To those that this med does not work, I say they are very wrong.  I have tried regular psuedofed and had to stop it due to excessive nervousness and insomnia.  This med on the other hand works great.  I have been taking it daily for 20 yrs and have to due to the my allergies/ ear disfunction.  If I miss a few days doses, I get an ear infection every time."
