Codeine, a narcotic, is apparently converted to morphine rapidly in the body in a small number of women. Codeine is a common ingredient in prescription pain relievers and some over-the-counter cough syrups. Women who convert codeine to morphine quickly are called ultra-rapid metabolizers. Their prevalence within the population varies between 1-28% depending on who gives the estimate, but it is believed that rates are highest among North African, Ethiopian and Saudi Arabian women.
This is just another reason why new mothers should be cautious of what they take. Drugs are routinely prescribed, but it does not mean they are without risk. You are always safer minimizing the chemical substances you ingest. This does not mean you shouldn’t have help if you need it, however, less is best. And knowing the latest in health information is crucial.
Now that you know that some women are ultra-rapid metabolizers of morphine, you can obtain a laboratory test through your doctor to determine if you fall into this category. Otherwise, ask your prescribing doctor what’s in the drug they’re recommending. If it contains codeine, ask for an alternative. And remember, sometimes it pays to just deal with the discomfort.
