Explaining the different classes of OTC allergy medications and their mechanisms of action

Main Classes of OTC Allergy Medications

When it comes to managing allergies, there are several classes of over-the-counter (OTC) allergy medications to choose from. These medications can help provide relief from common allergy symptoms, such as sneezing, itching, nasal congestion, and watery eyes. The three main classes of OTC allergy medications are antihistamines, decongestants, and nasal corticosteroids.

Antihistamines: Blocking the Effects of Histamine

Antihistamines are one of the most commonly used OTC allergy medications. They work by blocking the effects of histamine, a chemical released by the body during an allergic reaction. Histamine is responsible for causing common allergy symptoms such as itching, sneezing, and runny nose.

By blocking the effects of histamine, antihistamines help alleviate these symptoms and provide relief. They come in various forms, including tablets, capsules, liquids, and even chewable tablets for children. Some antihistamines may cause drowsiness as a side effect, while others are considered non-drowsy.

Decongestants: Reducing Nasal Congestion

If you’re dealing with nasal congestion, OTC decongestants may be the right choice for you. Decongestants work by constricting the blood vessels in the nasal passages, reducing swelling and congestion. This allows for easier breathing and relief from a stuffy nose.

You can find decongestants in various forms, including tablets, nasal sprays, and liquids.
