Saline nasal sprays, such as Salinex, are simple decongestants. They contain a saltwater solution to rinse your nose and help relieve mild congestion, loosen mucus, and prevent crusting. Though saline sprays can be useful for relieving symptoms of allergic rhinitis and have no side effects, saline can't prevent allergy symptoms from occurring, as some other allergy treatments can. (Preventive treatments include allergy shots [immunotherapy], antihistamines, mast cell stabilizers, and leukotriene inhibitors, as well as some natural treatments.)
