So symptoms and side-effects may go up and down all day long even when you're taking the medicine on the recommended schedule. The products we've recommended below have been chosen to avoid most of the pitfalls above.

Don't confuse this with decongestant nasal sprays, which can cause nasal dependence and other severe side-effects.
