No. Corex T Syrup contains codeine, which is a controlled medicine. Because of the risk of misuse and dependence, it cannot be sold online or delivered to homes. It is dispensed only through licensed offline pharmacies or hospital pharmacies and only upon presentation of a valid physical prescription. Importantly, since you have been experiencing throat pain, allergy, and cough for several years, it is best to consult your doctor again for a reassessment. A proper diagnosis is essential to identify the underlying cause of your persistent condition, rather than continuing long‑term use of this medication without review. Your doctor can guide you on safer, more effective treatment options tailored to your needs.
