FEXOFENADINE

FEXOFENADINE: Fexofenadine is an antihistamine drug used to treat the symptoms of allergies like hay fever, including sneezing, itching, watery eyes, and runny nose. It is available in both prescription and over-the-counter formulations.

The mechanism of action of fexofenadine involves blocking the action of histamine, a substance in the body that causes allergic symptoms. By inhibiting the histamine receptors, fexofenadine helps to relieve symptoms associated with allergies without causing significant drowsiness.

The usual recommended dose of fexofenadine for adults and children over 12 years of age is 180 mg taken once daily. For children aged 6-11 years, the recommended dose is 30 mg twice daily, and for children aged 2-5 years, it is 15 mg twice daily. The exact dosing instructions may vary, so it is best to follow the advice of a healthcare professional or read the instructions on the packaging.

Common side effects of fexofenadine include headache, drowsiness, dizziness, nausea, and dry mouth. These side effects are generally mild and not experienced by everyone. However, if any of these side effects persist or worsen, it is advisable to consult a doctor. In rare cases, fexofenadine may cause serious allergic reactions, such as difficulty breathing or swelling of the face, tongue, or throat. If any severe allergic reactions occur, immediate medical attention should be sought.
