Allergy medications can be taken as pills, liquids, inhalers, nasal sprays, eyedrops, skin creams and shots.1 Some medications require a prescription, while others can be purchased over the counter.1 How you choose to treat your symptoms will depend on your preferences. For instance, some people are bothered by the feeling of liquid running down their throats after using nasal sprays, and others may not feel like the ingredients in certain allergy pills work well for them. The different types of allergy medicines are antihistamines, decongestants, corticosteroids, mast cell stabilizers and allergy immunotherapy.1 Antihistamines, decongestants, corticosteroids and mast cell stabilizers can be taken in a variety of forms. Immunotherapy is a way to gradually expose the body to allergens through a series of injections, allergen-based tablets and biological medications.1 This process helps to train the body not to react to certain allergens.1
