Saline drops are the best choice because they address the mucosal congestion directly and safely. RSV causes inflammation and increased mucus in the nasal passages, leading to swelling and blockage. Icing in on that swelling with plain saline helps loosen and thin the mucus, moisturize the nasal lining, and make it easier to clear secretions—often improving breathing, feeding, and sleep. It’s a simple, nonpharmacologic option that is appropriate for children. Antibiotics don’t help with a viral infection like RSV, since there’s no bacteria to target, and using them unnecessarily can cause side effects and contribute to resistance. Corticosteroids and antihistamines aren’t routinely beneficial for nasal symptoms due to RSV in kids and can have limited effectiveness or unwanted effects. If needed, saline is used regularly to provide relief, sometimes followed by gentle suction to remove loosened mucus.
