How do nasal sprays with mast cell inhibitors, leukotriene inhibitors, and anticholinergics give nasal allergy relief?
Nasal sprays with mast cell inhibitors help prevent allergy symptoms such as runny nose or itchy eyes. These allergy medicines need several days to give good allergy relief and should be started up to one week before contact with allergens. Mast cell inhibitors are available without a prescription. Leukotriene inhibitors are particularly useful for combination therapy when a person has asthma, as well as allergies. These medicines help block the chemicals in the body that promote inflammation. Anticholinergics are useful allergy medicines if you have a clear, watery discharge (rhinorrhea) from the nose. These allergy medications may work with antihistamines. Anticholinergic nasal sprays give relief of allergy symptoms by reducing a runny nose.
