Codeine and promethazine are two commonly used medications that are often combined to treat a variety of conditions, such as cough, cold, and allergies. However, due to their potential for abuse and addiction, these medications are classified as controlled substances in many countries and are only available with a prescription from a healthcare provider. The price of these medications can vary depending on where they are purchased and whether or not they are covered by insurance.

In recent years, there has been a growing trend of online pharmacies offering codeine and promethazine for sale with overnight delivery. While this may seem convenient for those who need these medications quickly, it is important to exercise caution when purchasing medications online. There is always a risk of receiving counterfeit or substandard products when ordering medication from unknown sources. Additionally, buying prescription medications without a prescription is illegal and can have serious consequences.
