Codeine is an opiate used to treat mild to moderate pain and as a cough suppressant. It's similar to morphine but less potent, acting on the central nervous system to reduce pain signals. Think of it as a dimmer switch for pain rather than an off switch. While helpful, codeine can be addictive and cause side effects like drowsiness and constipation. It's often prescribed after minor surgeries or injuries. Codeine should be used cautiously, especially since genetic variations can affect how people metabolize it. Always follow your doctor's instructions.
