Re: Morphine & Respiratory Depression
Hello, and I'm sorry that your husband is having problems. As a general rule, any narcotic can bring on the side effects you describe. All narcotics are "depressants", thus, why they are sedating in nature. They slow down all bodily functions...Metabolism, breathing, digestive system, can cause ED in men, and etc.
Some people do experience a "paradoxical" effect, or opposite, and this is why some abuse them. The paradoxical effect is also why "like treats like" or why they give ADHD patients stimulants. In most patients, however, narcotics are more depressive in nature.
As far as morphine being worse than the others in terms of oxygen, I do not know. I do know that morphine can be more sedating in nature than some others. I would circle back and ask your Doc. Your pharmacist is also a great source of information, especially so because he/she has all the information re: all the meds your husband is on and the cumulative effect is important.
As far as your increase, the body will normally adjust in regards to it's normal functions (such as digestive and constipation for example). If your Doc gave him an increase, then he must feel it's ok. However, if you think his breathing is an issue, I would definitely bring it up. There are many other meds at your Doc's disposal. Pain mgt is a very individualized field...What works for one may not work for another. Additionally, it's not unusual for it to take a while to get everything dialed in correctly.
Take care, and good luck,
