Guaifenesin / phenylephrine
"I'm almost 43 and have had the worst allergies all my life. My medical records literally say "allergic to the world" Mostly suffering from sinus headaches and itching. I've tried EVERY medicine a doctor can prescribe. I did the shot thing in my teens. And when I was at the end of my rope with suffering when my doctor in Vermont said let's try this one last medicine. She told me it will totally work or do nothing. IT WORKED with no side effects and after two years of two pills a day, I was down to one pill most days. PLEASE bring Entex LA back. It would change my life. I now take so many over the counter pills and eyedrops. This medicine was like a miracle medicine to a person suffering with allergies all their life."
