I just picked up Deconex IR 10-385mg Tablets for my persistent cough and nasal congestion, and I'm impressed. The combo of guaifenesin and phenylephrine works great for me. I wanted to hear from others — what's your experience been like? Any weird side effects? I've been feeling a bit dizzy, but it could just be the allergy season.

I just took it last night and I felt dizzy this morning. Probably just the pills but I'm not too sure. Will stick to it for a day more and see how it goes. Thanks for posting, I'm going to keep reading the thread to see how others do.

If you're experiencing serious side effects like allergic reactions, please go to the ER immediately. Don't wait.

I’ve had some trouble sleeping since I started taking these but otherwise it’s been fine. I used to take Sudafed but I had to switch since it was giving me whacky side effects. I wish it didn't have that but it's ok for now.

I was on these for a bit but felt way too jittery. Might not be for everyone!

I've been using Deconex for a while now, and it's been a game-changer for my sinus issues. I had a bad allergic reaction to a different drug, but this one is working well.

Contact your doctor if you're feeling really weird. It's not worth risking it. I saw a dermatologist for my skin issues, they know more than we do. But for me, it hasn't given me any issues.

Do these cause any drowsiness? I can't afford to be sleepy at work.

Dude, don't be too worried, I think it’s common with lots of meds but probably nothing to worry about. I'll keep taking them and let ya know how it goes.
