Nasal sprays, while offering quick relief from congestion, can paradoxically exacerbate the problem with extended use. Dr. Ovidiu Nicu, an ORL specialist, cautions against relying on sprays for long-term solutions. Prolonged use can maintain nasal blockage instead of resolving the underlying cause. Rather than simply masking symptoms, individuals experiencing weeks-long congestion should seek to identify the root issue. The expert emphasizes that addressing the cause is crucial for lasting relief. Using nasal sprays for too long can lead to a cycle of dependence and worsening congestion. Seeking professional medical advice is recommended for persistent nasal blockage.
