Types of otc allergy medications

There are several types of OTC allergy medications, each targeting specific symptoms and mechanisms of allergic reactions. These include:


Antihistamines are one of the most common types of OTC allergy medications. They work by blocking the action of histamine, a chemical released by the body in response to allergens. This helps alleviate symptoms such as sneezing, itching, and runny nose. Some popular antihistamines available without a prescription include cetirizine (Zyrtec), loratadine (Claritin), and diphenhydramine (Benadryl).


Decongestants are another type of OTC allergy medication commonly used to relieve nasal congestion caused by allergies. They work by constricting blood vessels in the nasal passages, reducing swelling and congestion. Examples of OTC decongestants include pseudoephedrine (Sudafed) and phenylephrine.

Nasal sprays

Nasal sprays can provide targeted relief for nasal allergy symptoms. They come in two main types: saline sprays, which help rinse away allergens and irritants from the nasal passages, and steroid nasal sprays, which reduce inflammation and swelling. Popular OTC nasal sprays include Flonase (fluticasone) and Nasacort (triamcinolone).

Eye drops

For those experiencing allergy-related eye symptoms such as itching, redness, and watering, OTC eye drops can provide relief. These drops typically contain antihistamines or other ingredients to alleviate eye irritation caused by allergies. Examples include ketotifen (Zaditor) and naphazoline/pheniramine (Naphcon-A).

Choosing the right otc allergy medication

With so many options available, choosing the right OTC allergy medication can seem overwhelming. Here are some factors to consider when selecting an OTC allergy medicine:


Consider which symptoms you’re experiencing and choose a medication specifically formulated to target those symptoms. For example, if you have a runny nose and sneezing but no congestion, an antihistamine may be sufficient. However, if nasal congestion is a significant symptom, you may benefit from a combination of antihistamines and decongestants.

Side effects

Be aware of potential side effects associated with OTC allergy medications. While antihistamines are generally well-tolerated, they can cause drowsiness in some individuals. Decongestants may cause increased heart rate and elevated blood pressure in some people. It’s essential to read the labels carefully and follow the recommended dosage instructions.

Drug interactions

Some OTC allergy medications may interact with other medications you’re taking. Always consult with a healthcare professional or pharmacist before starting any new medication, especially if you’re taking prescription medications or have underlying health conditions.
Over-the-counter allergy medications can provide effective relief for mild to moderate allergy symptoms without the need for a prescription. By understanding the different types of OTC allergy medications available and considering factors such as symptoms, side effects, and drug interactions, individuals can choose the right medication to manage their allergies effectively. However, if symptoms persist or worsen despite OTC treatment, it’s essential to consult with a healthcare professional for further evaluation and guidance.
