Which Allergy Medicine is Best? Exploring Your Options

Are you suffering from allergies? You’re not alone. According to the Asthma and Allergy Foundation of America, allergies affect more than 50 million people in the United States. Luckily, there are plenty of allergy medicines available to help you manage your symptoms. But with so many options out there, how do you figure out which one is the best? In this article, we’ll explore the mechanisms of allergy medication, compare popular options, rank the top allergy medications, discuss ingredients and potential side effects, look at different types of allergy medication, and provide practical advice for choosing the right allergy medicine for you.

How Do Allergy Medications Work?

To understand how allergy medication works, it’s important to understand what allergies are. Allergies occur when your immune system overreacts to a substance that is typically harmless, called an allergen. This can be anything from pollen to dust mites to certain foods.

Allergy medication works by targeting specific parts of the allergic reaction. For example, antihistamines block the effects of histamine, a chemical released by your immune system in response to an allergen. Decongestants help relieve nasal congestion by narrowing blood vessels in your nasal passages. Nasal steroids reduce inflammation in your nasal passages.

Comparing Allergy Medication Options

Now that we know how allergy medication works, let’s take a closer look at the most popular options and compare their effectiveness, side effects, and cost.


Antihistamines are the most common allergy medication. They come in both over-the-counter and prescription forms. They’re typically taken orally and can provide relief for symptoms such as sneezing, itching, and runny nose. Popular antihistamines include:

  • Claritin (Loratadine)
  • Zyrtec (Cetirizine)
  • Allegra (Fexofenadine)

According to a study published in the Journal of Allergy and Clinical Immunology, Claritin and Zyrtec were found to be equally effective in treating seasonal allergies. Allegra was found to be slightly less effective. Common side effects of antihistamines include drowsiness, dry mouth, and dizziness. They’re generally considered safe for most people to use. Antihistamines are also relatively inexpensive with over-the-counter options costing as little as $10 for a month’s supply.


Decongestants, like antihistamines, are typically taken orally and come in both prescription and over-the-counter forms. They work by reducing swelling in the nasal passages, making it easier to breathe. Popular decongestants include:

  • Sudafed (pseudoephedrine)
  • Afrin (oxymetazoline)
  • Clarinex-D (desloratadine and pseudoephedrine)

Sudafed and Afrin are available over-the-counter, while Clarinex-D is a prescription medication. Decongestants can cause side effects such as increased heart rate and blood pressure, insomnia, and anxiety. They’re usually not recommended if you have high blood pressure or other heart conditions. Decongestants are generally less expensive than antihistamines, but Clarinex-D can cost up to $200 for a month’s supply.

Nasal Steroids

Nasal steroids are prescription medications that are sprayed into the nose to reduce inflammation. They’re usually recommended for people with moderate to severe allergy symptoms. Popular nasal steroids include:

  • Flonase (fluticasone)
  • Nasonex (mometasone)
  • Rhinocort (budesonide)

A study published in the Annals of Internal Medicine found that nasal steroids were more effective in relieving allergy symptoms than either antihistamines or decongestants. Common side effects of nasal steroids include nosebleeds, headaches, and sore throat. They’re generally considered safe for most people to use. Nasal steroids tend to be more expensive than antihistamines and decongestants, with a month’s supply costing anywhere from $40 to $200 depending on the specific medication and insurance coverage.

Ranking the Top Allergy Medications

So which allergy medicine is the best? It really depends on your individual needs and preferences. Factors that can influence the effectiveness of allergy medication include the severity of your allergies, the type of allergen you’re exposed to, and any other health conditions you may have. Here are some rankings based on real customer reviews and expert opinions:

  • Most Effective: Nasal steroids
  • Most Convenient: Antihistamines
  • Most Immediate Relief: Decongestants
  • Best for Long-Term Maintenance: Immunotherapy (allergy shots)

Ingredients and Potential Side Effects

Now let’s take a closer look at the ingredients found in allergy medication and their potential side effects.

Common Ingredients

As we’ve already discussed, different types of allergy medication contain different active ingredients. Here are some of the most common:

  • Loratadine
  • Cetirizine
  • Fexofenadine
  • Pseudoephedrine
  • Oxymetazoline
  • Fluticasone
  • Mometasone
  • Budesonide

Common Side Effects

Most allergy medications, regardless of the type, have some potential side effects. Here are some of the most common:

  • Drowsiness
  • Dizziness
  • Dry mouth
  • Insomnia
  • Nausea
  • Headache
  • Nosebleeds
  • Sore throat

Drug Interactions

It’s also important to be aware of potential drug interactions when taking allergy medication. For example, antihistamines can cause drowsiness and increase the effects of alcohol or other sedatives. Decongestants can increase blood pressure and should not be taken if you have high blood pressure or other heart conditions. Nasal steroids may interact with other medications, including certain antibiotics and antifungal drugs. Be sure to talk to your healthcare provider about any medications you’re taking before starting a new allergy medication.

Different Types of Allergy Medication

Now that we’ve covered the most popular allergy medication options, let’s talk about the different types of medication available and their pros and cons.


Pills are the most common type of allergy medication. They’re convenient and easy to take, but they can cause systemic side effects like drowsiness and dry mouth. Pills can also take longer to provide relief than other types of medication.

Nasal Sprays

Nasal sprays deliver medication directly to your nasal passages, making them a good choice if you have persistent nasal symptoms. However, they can cause nasal irritation and nosebleeds.

Eye Drops

Eye drops are designed to relieve eye-related allergy symptoms like itching and watering. However, they may cause stinging or burning in your eyes.


Liquids are a good option for children or adults who have trouble swallowing pills. However, they can be less convenient to take and may not provide as much symptom relief as other types of medication.

Practical Advice for Choosing the Right Allergy Medication

Choosing the right allergy medication can seem overwhelming, but with a little guidance, you can find a medication that works well for you. Here are some tips:

  • Talk to your healthcare provider about your allergies and symptoms to get personalized advice.
  • Consider the severity of your allergies and the type of allergen you’re exposed to when choosing medication.
  • Focus on finding a medication that effectively manages your symptoms with minimal side effects.
  • Check with your insurance company to see what allergy medications are covered and at what cost.


Allergy medication can be incredibly helpful in managing allergy symptoms that can otherwise disrupt your day-to-day life. By understanding the different types of allergy medication, the active ingredients they contain, and their potential side effects, you can make an informed decision about which medication is the best fit for you. Don’t hesitate to reach out to your healthcare provider to discuss your options and find the allergy medication that works best for you.
