Veramyst - clears the allergies, makes you blind, maybe

On Wednesday night I'm watching NBC and a commercial is forced upon me for Veramyst. Now, suffering from the occasional allergy, I pay attention. If you get the chance to see this commercial, watch it, you'll enjoy it. It will help with allergies (maybe). It (may) cause a fungal infection in your nose. Interestingly enough, it (may) also cause glaucoma and cataracts! And, as if that wasn't enough, about midway through the commercial is some fine print at the bottom of the screen which reads "It is not completely known how Veramyst works." Yeah.
