Doctor’s Review

Dr. Ayesha Malik (Consultant Allergist):
“Zyrtec is one of the most widely prescribed antihistamines for allergy management. It provides fast relief with minimal sedation compared to older antihistamines. However, patients with kidney problems or certain allergies should use it with caution. Always consult your doctor for the correct dose, especially for children.”
