Fexofenadine in the 20 ml form is usually a liquid suspension used to treat allergy symptoms, such as sneezing, runny or itchy nose, and itchy or watery eyes, typically caused by hay fever or other allergic conditions. It is also effective in alleviating symptoms of chronic urticaria (hives), including itching and rash. Fexofenadine works by blocking histamine, a substance in the body that triggers allergic responses. As a second-generation antihistamine, it is less likely to cause drowsiness compared to older antihistamines. The 20 ml suspension is often recommended for those who have difficulty swallowing tablets, such as children or individuals needing a lower dosage. It provides long-lasting relief, typically lasting up to 24 hours
