"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, 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 eye drops. This medicine was like a miracle medicine to a person suffering with allergies all their life."

"I found Entex LA to be a very good sinus dryer that could prevent a sinus infection or go a long way to curing one when an antibiotic was added. Unfortunately, Entex has been removed from the US market by the FDA. It seems to me that when a drug is found that works extremely well and is cheap, the end result is it's either removed from the market by the FDA or the drug companies cease to manufacture it because of low profit motive. I know of no replacement for Entex LA."

"I get sinus headaches when it rains, when it's extremely humid, or when it's extremely cold. Entex LA would get rid of the headache within a couple of hours. I am told that they cannot sell Entex LA in the US anymore since the FDA banned it. This is the only thing that would work for me. I would love to have this drug back on the market. The pharmacist told me that many of her customers were frustrated when it was taken off the market."

"Entex LA was recommended by a pharmacist and never looked back. Went into pharmacy with a list an arm's length long of products I'd tried that never worked. Symptoms so severe for a year it felt like someone trying to stuff a brick up my sinuses and affected my whole demeanor. No, this is nothing like Mucinex - that almost put me in the hospital with such low blood pressure I was going to pass out at work - on a construction site where I do first aid and safety."

"I had sinus problems several times per year (spring/fall) for years, and everything made me groggy. I could barely walk. Then the doctor started me on Entex LA, and my sinus problems no longer caused major problems."

"Entex LA was the only drug that ever helped my 20-year chronic sinus drainage that I suffer with! Before Entex LA was discontinued, I took Entex LA for several years on an as-needed basis. I had no side effects with it. Mucinex, Claritin, antihistamines, and many other OTC drugs don’t work as well, and it feels slow to get/feel any improvement. Please bring Entex LA back."

"I ended up in intensive care after taking this medication. Severe headache, projectile vomiting. It was terrible. Once the pill was out of my system, I felt so much better. Then the medication was recalled because so many people reacted to it. At least this is what I was told from the pharmaceutical company after they did a follow-up on me. It was very traumatizing for me because I had never before reacted to any medication. I was worked up for an aneurysm, but it was the medication."

"Not sure why this is discontinued, works awesome, it's the only drug (including prescribed) that seems to help my sinuses."

"This is the only medication that works for me when I have a cold or get a sinus infection. Even prescriptions don't work as well. Why has it been discontinued, and how can we get it back? Please bring it back!"
