Mind drugs symptoms and conditions

I have been on Nasonex for approx 7 days now, I was at the gym last night and my chest felt ooh so tight, am coughing as bad as I always have and I cannot taste or smell now(no flavor, nor senses). My nose is running all of the time and I do not fancy getting any more side effects so Nasonex from today is going bye bye, never mind drugs are for mugs, but 'Nasonex is for MUGS'..... don't feel like being a hamster or a guinea pig, why prescribe and not remove from the market a product with obviously so many downsides.
