Pain killing morphine?

how long does morphine stay in your system for
Answer:
About 3 days...A single 10 mg dose administered intravenously produces an average initial serum concentration of 60 ng/mL which declines rapidly then levels off to a concentration of 3 ng/mL for up to 36 hours. An equivalent dose administered intramuscularly produces similar results, 70 ng/mL at 10 to 20 minutes and 20 ng/mL in 4 hours. The metabolite morphine -3-glucuronide appeared in serum within 20 minutes of administration and exceeded morphine concentrations after 2 hours. The plasma half-life of morphine in surgical patients averaged 1.08 hours in women and 2.9 hours in men. URINE EXCRETION RATE: Up to 87% of a dose of morphine is eliminated in the 72 hour urine. Morphine glucuronide makes up 75% of the eliminated dose. Free morphine accounts for approximately 10% of the dose. Codeine that shows up in the urine following morphine administration is a result of the impurity of commercial morphine (0.04%).
It can depend on how often a day the medication is taken. If it is a dosage of every 12 hours the medicine may last about 11 hours or the full 12 til the next dosage.I would also recommend checking with your pharmacist to see what they say.
3 days
I had to take moraphine for kidney stones it shouldnt take long maybe up to 12 hours no longer. But you SHOULDNT take it for any other reason then that!
morphine generally exerts it pain relieving qualities for up to an hour, before requiring a top up dose.
however, the drug stays in your system for much longer, until it is metabolised by the liver and kidneys and excreated out in the urine. This whole rocess can take up to 2-3 days dependant on the dose given
I was on a lot of morphine when I had a horse riding accident 5 years ago.For most it is out of your system within three days and not usually addictive if you take it for pain.There have been studies done that show that patients in severe pain can take morphine with few side effects including addiction at levels that would kill someone who is not in pain - morphine seems to adhere to those nerve endings/receptors causing pain And if you are in pain there is less chance of addiction ot tolerance.PS My husband works at sea and is drug tested and can not have any drug like this in his system wen he goes to sea - for morphine even for pain control he would have to leave at least 7 days between his last dose and going to sea
The effects of the medication only last for an hour or so, but the drug can be found in traces in your system for months.
72 hours..its water soluable.
