What does rebound congestion refer to?

Rebound congestion is a phenomenon that occurs when the nasal passages become congested again after the use of a decongestant, particularly those that are intranasal. Initially, these medications provide relief from nasal congestion by constricting blood vessels in the nasal tissues, leading to decreased swelling and improved airflow. However, with prolonged use, especially beyond the recommended period, the body may react by increasing congestion once the medication is stopped, often resulting in a cycle where patients feel compelled to continue using the decongestant to alleviate the worsening symptoms. This can create a dependence on the medication, making rebound congestion a common concern for individuals using over-the-counter nasal sprays for extended periods. Understanding this phenomenon is essential for proper medication management and patient education regarding the risks associated with overuse of decongestants.
