Why this happens
Zomorph is a brand name for a 'modified-release' version of morphine. Both medications contain the same active ingredient (morphine). Taking both at the same time leads to an additive effect, where the total amount of morphine in your system may exceed safe levels.
What you should do
Do not take these two medications together unless specifically instructed by a pain specialist. If you have been prescribed both, check with your doctor or pharmacist to ensure you are not duplicating your dose. If you experience extreme drowsiness or difficulty breathing, seek emergency medical help immediately.
