Allergy medication helps relieve symptoms caused by allergic reactions, such as sneezing, itching, and runny nose. Common types include antihistamines, which block the action of histamine, a substance released during an allergic response. Other options are decongestants, which reduce nasal congestion, and corticosteroids, which decrease inflammation. These medications can be available over-the-counter or by prescription, depending on their strength and formulation. It's important to follow dosage instructions and consult a healthcare professional if symptoms persist. Some people may also benefit from allergy shots or other treatments to manage their allergies more effectively.
