Some symptoms of allergies can be controlled by medications. Effective medications that can be prescribed by a doctor include antihistamines and topical nasal steroids. Antihistamines may help dry up a runny nose and relieve sneezing, and itching in the nose, throat, and eyes. They can also reduce nasal swelling and drainage. They should not be used when congested because they can thicken mucus making it more difficult to drain.
Decongestants are drugs that can help re-establish drainage of the nasal passages.
They can sometimes help relieve symptoms of congestion, swelling, sinus pressure and stuffy nose and ears. Topical Nasal Steroids are anti- inflammatory drugs that stop the allergic reaction. They can help reduce mucous secretions and nasal swelling. When used in combination with antihistamines, they can be an effective way to treat allergic rhinitis. These should only be used at recommended doses.
