Nasal medications (nose sprays) for allergies are available in a few different classes.
Nasal medications for allergies available in Canada include:
Nasal decongestants provide temporary relief from congestion. However, they should not be used for more than 3 to 7 days because nasal congestion can return or get worse once you stop the medication. Since allergic rhinitis usually requires long-term treatment, it's best to talk to your doctor or pharmacist about which medication is right for you.
Mast cell stabilizers help with nasal itchiness, sneezing, and runny nose. They work by stopping the action of mast cells, which are thought to be involved in your body's allergic reaction response. They work best when used as a preventative measure, before allergy symptoms start. Otherwise, it may take up to 4 weeks to feel relief. Dosing may be up to 4 times a day. Side effects may include local irritation, sneezing, stinging, bad taste in the mouth, and nosebleeds.
Antihistamines help relieve nasal itchiness, sneezing, and runny nose. They work by stopping the action of histamine, which is a substance in your body that causes an allergic response when you are exposed to an allergen. It is used 2 to 4 times a day. Side effects may include nasal irritation, drowsiness, nosebleeds, dry mouth, and headaches.
Anticholinergics are used to relieve a runny nose associated with allergies. They work by blocking the secretion of mucous in the nose. It is used 2 or 3 times a day. Side effects may include headaches, nosebleeds, nasal irritation, dry nose, and sore throat.
Corticosteroids are used to help relieve the symptoms of allergic rhinitis, including itching, congestion, runny nose, and sneezing. They work by locally reducing inflammation in the nose that is involved in an allergic reaction. The dosing of corticosteroids is once or twice a day, depending on the medication selected. Side effects of corticosteroids may include burning, stinging, nasal irritation, headaches, nosebleeds, sore throat, changes in taste, and dry mouth.
Each person may respond differently to medications and some not everyone experiences the same side effects. If side effects are a concern for you, talk to your doctor about which nasal spray would best suit you.
