How long does it take for extended release morphine to start working?

Answer 1

Usually 20-30 minutes. In a trauma situation, paramedics will usually give you a drug called Fentanyl, which is 100x stronger than morphine and starts to take effect usually 30 seconds to a minute in. Afterwards, they will also give you Morphine. Morphine takes longer to kick in but lasts longer than Fentanyl so once the Fentanyl wears off, you still have a good dose of pain killers in you via Morphine.

Answer 2

I have been taking Morphine Sustained Release for about 2 years now and I would say depending on if your taking it on an empty stomach or not, it takes about a half an hour to take effect. Hope this helps.

Answer 3

Pain relief from morphine, or at least how long it takes to feel its first effects, depends on route of administration and one's metabolism. If taken intravenously, morphine acts within a few minutes. If taken orally it can be felt in as few as 20-30 minutes. Some folks have a metabolism that can cause morphine and other opioids to take longer to take effect than for other people. Finally, some drugs can cause morphine to be less effective and less easily felt. See your doctor for more definitive information, as he/she knows you, your medical history and how morphine would react in the presence of other medications you take.
