You should not use Apollo Pharmacy Itch Prevention Cream on your lips because it contains Clotrimazole, Menthol, Boric Acid, and Zinc Oxide, which are meant for skin use only and can irritate or harm the delicate mucous membranes of the lips. Applying it there may cause burning, irritation, or harmful reactions if ingested. For itchy or irritated lips, safer alternatives include plain petroleum jelly, regular lip balm, or medicated lip balms designed for lip irritation or infections. If symptoms like cracking, redness, or swelling persist, consulting a dermatologist is recommended.
