My favourite sinus med used to be Entex LA. It was the only thing that cleared out my sinuses and unblocked my eustachian tubes and it didn't make me drowsy. It had phenylpropanolamine in it, though, and apparently it's dangerous (associated with hemorrhagic stroke) so they took it off the market in Canada. It's a banned substance here now. There's a revised version of Entex available in drugstores now (with phenylephrine in place of phenylpropanolamine), but it doesn't work as well.

Why does the stuff that works always turn out to be bad for us?
