Wanting to find out what Phenavent D 40-120 Tab Ethex is for and the side effects. Thank You. ## Hello, Ethel! How are you? The FDA lists Phenavent D as containing Guaifenesin and Phenylephrine, it is a decongestant and expectorant that is most commonly used to treat cold symptoms. Its typical side effects may possibly include nausea, dizziness, headache, dry mouth and nervousness. Is there anything else I can help with?

Need to identify imprint "ETX" "AE" small white tablet...possibly from Korea? ## Hi John, I haven't been able to find any pills from the U.S. with that imprint, the closest match I've found is a white oblong pill with ETHEX on one side and on the other side- 444 on the right of score. I have identified it as Phenavent D; which contains Guaifenesin + Phenylephrine. That combination is used as an expectorant and decongestant. It is definitely possible that your pill comes from foreign source. What makes you think it came from Korea?
