Re: Can decongestants dry you out and cause more harm?
Repeated use of decongestant sprays causes a rebound effect, which can turn into a lifelong problem as it has in me. I wish I'd never heard of the stuff! The more you use it the more your nose stuffs, and the more you think you need to use it. I ended up having 2 nose surgeries to try and fix some of the damage that spray did to my membranes! End result -- I developed vasomotor rhinitis, which is basically like being allergic to life. Allergy symptoms are based on feelings as well as irritants, and the irritants aren't always the same.
If you ever need a decongestant it is better to take it in a pill form. Otherwise use only saline spray as others recommend.
