It is not a narcodic so it won't matter how long it's in your system as it is not tested for
I take Soma and Morphine Sulfate 30mg at the same time every day. I think it all depends on the person. If you have never taken these things before and have a low tolerance I suggest you not take them together. If your doctor has prescribed them, than have a friend or family member stay with you when you first take it so you can have help if you need it. Also are you taking a long acting muscle relaxant and morphine dose or short acting? Many times with sports injuries this is the best course of treatment. So I would say if a doctor prescribed it, you could try it. See how you feel on the muscle relaxant alone then see how you feel on the morphine alone. You will definitely not be walking around your first few doses. It is all about a tolerance level. good luck and definitely have someone with you at all times the first few doses until you can get the feel of how you will react. It may lower your blood pressure and heart rate mare than is safe [=fatal]. If you insist on doing this, just take a half of each tab, or less. And see how that goes. And for god's sakes, while you're under the influence, monitor your vitals. Like, with medical instruments (e.g. stethescope and pressure cuff).
Yes. You can. They are in different drug catagories. I just went to Urgent Care today, for pulling muscles in my back while at work. The Doctor prescribed me Skelaxin & Lortab (Vicodin). She said specifically, that it is safe to take the two at the same time (only taking the recommended dose.)
