Loratadine is an antihistamine medication commonly used to relieve allergy symptoms such as sneezing, runny nose, and itchy eyes. It works by blocking the action of histamine, a substance in the body that causes allergic reactions. Loratadine is available over-the-counter and is often preferred because it typically does not cause drowsiness, making it suitable for daytime use. This medication is effective for seasonal allergies and can also help with symptoms of hay fever. Loratadine is usually taken once daily, and it comes in various forms, including tablets, liquid, and dissolvable strips. Always consult a healthcare professional before starting any new medication.
