What are Allergies?
Allergies occur when your body reacts to certain substances. If you have allergies, your body’s immune system produces antibodies that classify the allergen as harmful to you even though it isn’t. Common allergens include dust, pollen, mold, pet dander, and even certain foods (however, there are many more).
Allergy symptoms can be intermittent (occasionally) or chronic (regularly). Intermittent symptoms can occur when exposed to allergens, while chronic symptoms can occur due to seasonal changes.
What are Allergy Medications?
Allergy medications ease symptoms such as sneezing, itching, and stuffy noses. They come in different forms, including pills, liquids, nasal sprays, eye drops, skin creams, and injections.
Some allergy medications can be bought over the counter, while others require a prescription.
Allergy medications often include antihistamines, decongestants, corticosteroids, or a mix of these.
Immunotherapy, such as allergy shots or tablets, can help build long-term tolerance.
While there is no cure for allergies, the right medication can make managing symptoms easier.
Types of Allergy Medications
Different types of allergy medicines work in distinctive ways to provide relief.
Take a look at the different types of allergy medications below, including antihistamines, corticosteroids, decongestants, and more.
Antihistamines
Antihistamines help relieve allergy symptoms like sneezing, itching, hives, and watery eyes.
They are also used for insect bite reactions, motion sickness, nausea, and short-term insomnia treatment.
These medications come in two main types: drowsy antihistamines, like Benadryl (diphenhydramine) and Phenergan (promethazine), and non-drowsy options, like Claritin (loratadine), Zyrtec (cetirizine), and Allegra (fexofenadine).
They are available as tablets, capsules, liquids, nasal sprays, and eye drops. Many antihistamines can be purchased over the counter, but some require a prescription.
Follow dosage instructions and ask a pharmacist or doctor if you are unsure how to take them.
| First Generation Oral Antihistamines | Second Generation Oral Antihistamines |
| Aller-Chlor | Allegra |
| Benadryl | Claritin |
| Dayhist Allergy 12 HR Relief | Clarinex |
| Xyzal Allergy* | |
| Zyrtec* |
*Most sedating second-generation oral antihistamines
Corticosteroids
Corticosteroids can help reduce inflammation and swelling caused by allergies. They come in both nasal and oral forms.
Nasal sprays like Flonase (fluticasone) and Nasonex (mometasone) are often used to treat congestion. Oral corticosteroids, such as Prednisone and Medrol (methylprednisolone), are typically prescribed for more severe allergies or skin reactions.
Nasal corticosteroids take some time to work, but they are not addictive and can be used over the long term.
Oral corticosteroids are stronger, but they are usually taken for short periods because of potential side effects like weight gain, high blood pressure, and mood changes.
Mast cell stabilizers
Mast cell stabilizers help prevent allergic reactions by stopping mast cells from releasing histamine and other symptom-causing chemicals.
They work best when used before exposure to allergens.
Common options include nasal sprays like Nasalcrom (cromolyn sodium) and eye drops such as Alomide (lodoxamide) and Zaditen (ketotifen).
Unlike antihistamines, these medications do not provide quick relief but are useful for long-term allergy management.
They are often for people who cannot tolerate corticosteroids or need extra support to control symptoms.
Decongestants
Decongestants help clear a blocked nose by reducing nasal passages’ swelling, making breathing easier.
They can provide temporary relief from colds, flu, hay fever, sinus infections, and allergies.
These medications come in different forms, including nasal sprays, tablets, liquids, and dissolvable powders.
Popular options include Sudafed (pseudoephedrine) and Afrin (oxymetazoline).
Decongestants work fast, but do not use them for more than a few days, as they can worsen congestion.
People with high blood pressure or other medical conditions should talk to a doctor before using them.
Leukotriene inhibitors
Leukotriene inhibitors manage asthma and allergies by blocking the action of leukotrienes.
Leukotrienes are chemicals your body releases when exposed to allergens. They cause inflammation, swelling, and tightening of your airways.
These medications, like montelukast (Singulair), zafirlukast (Accolate), and zileuton (Zyflo), either stop your body from making leukotrienes or prevent them from causing problems.
They mainly treat asthma, allergies, and symptoms like shortness of breath or wheezing.
Leukotriene comes in pill form, making it easy to take regularly for long-term relief.
Emergency allergy medicine
Emergency allergy medicine is important for handling severe allergic reactions like anaphylaxis, which can be life-threatening.
It quickly reverses severe symptoms like low blood pressure, poor circulation, swelling, and trouble breathing.
Epinephrine also helps with skin and stomach problems caused by the reaction. In addition to epinephrine, the emergency kit may contain H1 and H2 antihistamines, albuterol (used for asthma), and steroids.
These help control the symptoms and stop the reaction from worsening, providing fast relief during an emergency.
Intranasal Steroids
Intranasal steroids are the first-line agents used for chronic, moderate-severe allergy symptoms. Intranasal steroids target nasal symptoms such as sneezing, itching, and runny nose by decreasing inflammation. Both adults and pediatric patients can use them. Common intranasal steroids include Rhinocort Allergy, Flonase Allergy Relief, and Nasacort Allergy 24HR. Intranasal steroids require at least a week of use before symptomatic relief. Common side effects include nose bleed, headache, and dry nose. It is important to note that the same steroids used to treat allergies and asthma have different brand names, and delivery systems. Therefore, doses can’t be used interchangeably.
| Over-the-Counter Intranasal Steroids | Prescription Intranasal Steroids |
| Flonase | Beconase AQ |
| Nasacort | Nasonex |
| Rhinocort Allergy | Omnaris |
| Qnasl | |
| Zetonna |
Intranasal Decongestants
Intranasal decongestants should be used with caution in patients with cardiovascular disease, high blood pressure, thyroid disease, diabetes, and BPH. They have a fast onset of around 5-10 minutes. Common side effects include rebound congestion, nasal stinging, dry nose, and sneezing.
Oxymetazoline is the active ingredient in intranasal decongestants such as Afrin and Vicks Sinex. Products containing oxymetazoline should not be used for more than three days as prolonged use will cause rebound congestion.
| Systemic Oral Decongestants | Intranasal Decongestants |
| Nexafed | Afrin* |
| Sudafed | Phenylephrine |
| Sudafed PE | Vicks Sinex 12 Hour* |
| Zephrex-D |
*Should not be used for more than 3 days
Eye Drops
Eye drops can help relieve itchiness, dry eyes, and redness. Eye drops used to relieve dry eyes are often called artificial tears. They contain lubricants and should be administered multiple times a day as needed.
Oxymetazoline is the active ingredient in intranasal decongestants such as Afrin and Vicks Sinex. Products containing oxymetazoline should not be used for more than three days as prolonged use will cause rebound congestion.
| Eye Drops for Itchiness | Eye Drops for Dryness (Artificial Tears) | Eye Drops for Redness |
| Alaway (OTC) | Liquifilm Tears (OTC) | Clear Eyes Redness Relief (OTC) |
| Azelastine | Refresh (OTC) | Lumify (OTC) |
| Cromolyn | Systane (OTC) | Naphcon A (OTC) |
| Pataday (OTC) | Visine (OTC) | |
| Patanol (OTC) | ||
| Zaditor (OTC) |
Oral Leukotriene Receptor Antagonist
Singulair (montelukast) is an oral leukotriene modifying agent commonly used to treat allergies and asthma in children. Montelukast is only available with prescriptions and should be reserved for individuals who do not find symptomatic relief with other allergy medications.
Immunotherapy
Immunotherapy is a preventative treatment for allergies that slowly increases exposure to the allergen, causing the immune system to become less sensitive to it over time. Long-term immunotherapy can relieve symptoms even after stopping treatment. Immunotherapy is recommended for a minimum of three years. Immunotherapy can be administered through injections or sublingual (direct absorption) treatments.
All injections and the first sublingual treatments must be administered in a medical office. However, patients can take the following sublingual doses at home if it’s tolerated. The FDA has approved four sublingual immunotherapy treatments with specifically targeted allergens. It is recommended that patients have an epinephrine auto-injector (commonly known by the brand name EpiPen) while on this type of immunotherapy so there is a fast solution if there is an allergic reaction.
| Sublingual Immunotherapy Treatment | Allergen |
| Grastek | Timothy grass pollen extract |
| Odactra | House dust mite extract |
| Oralair | 5 grass pollen extract |
| Ragwitek | Ragweed pollen extract |
