Why do topical decongestants cause rebound congestion?
Topical Nasal Decongestants Beta-phenylethylamine derivatives mimic the effects of the sympathetic nervous system stimulation by producing vasoconstriction via the activation of alpha-1 adrenoreceptors. Rebound vasodilation may occur due to weak affinity towards beta–adrenoreceptors.

What is the difference between a decongestant and an antihistamine?
