Taking codeine and morphine together significantly increases the risk of serious side effects, including extreme sleepiness, dizziness, and dangerous breathing problems. Because both drugs are strong painkillers from the same family (opioids), they 'stack' on top of each other, which can lead to an accidental overdose.

Why this happens
Both codeine and morphine work by attaching to the same receptors in the brain and spinal cord to block pain. Additionally, the body naturally converts a portion of codeine into morphine after you swallow it. Taking both means you are essentially taking a double dose of morphine, which can overwhelm the central nervous system.
What you should do
You should not take codeine and morphine together unless specifically instructed and closely monitored by a specialist. If you have been prescribed both, speak to your doctor or pharmacist immediately to clarify the dosing schedule. Seek emergency medical help if you experience extreme drowsiness, confusion, shallow breathing, or difficulty waking up.
