Is morphine intramuscular or intravenous?

Is morphine intramuscular or intravenous?

Morphine Sulfate may be given by the subcutaneous, intramuscular or intravenous route. The subcutaneous route is not suitable for oedematous patients. The dosage should be based on the severity of the pain and the response and tolerance of the individual patient.

What is the difference between IM and IV injection?

IV, or intravenous, injections are administered into the bloodstream either by a syringe or by a low pressure method known as a drip. The intramuscular shots are administered into the muscle, not the vein.

Can you give morphine sulphate IV?

Morphine sulfate is an opioid agonist indicated for the management of pain not responsive to non narcotic analgesics. Morphine Sulfate Injection is intended for intravenous administration. Morphine Sulfate Injection is available in five concentrations for direct injection.

What absorbs faster subcutaneous or intramuscular?

Intramuscular injections are absorbed faster than subcutaneous injections. This is because muscle tissue has a greater blood supply than the tissue just under the skin. Muscle tissue can also hold a larger volume of medication than subcutaneous tissue.

Why is IM preferred over IV?

Intramuscular injections may be used instead of intravenous injections because some drugs are irritating to veins, or because a suitable vein can’t be located. It may be used instead of oral delivery because some drugs are destroyed by the digestive system when a drug is swallowed.

Which is more painful IV or IM?

IM injections are more painful than spinal and intravenous injections (Simini 2000; Cupitt & Kasipandian 2004 ).

Is IM faster than IV?

The IV group experienced a significantly faster onset of analgesic effect than the IM group (5 minutes versus 20 minutes). During 5–25 minutes after morphine administration, pain status in the IV group was significantly improved compared with the IM group.

Can I give IV injection in IM?

The intramuscular route is used where effects are desired over a longer period of time than can be expected after intravenous injection, for drugs that are too irritant to be given subcutaneously, or for oily solutions, which cannot be given intravenously.

What are the disadvantages of intramuscular injection?


  • Expert and a trained person is required for administrating the drug by IM route.
  • The absorption of the drug is determined by the bulk of the muscle and its vascularity.
  • The onset and duration of the action of the drug is not adjustable.

Which is faster IM or IV?

Why do intramuscular injections hurt so much?

“Muscles have little tight fibers, and if you separate it by sticking a needle in there, you can cause an inflammatory reaction,” she said. “When you have inflammation, you can end up having pain. And, when you get a muscular injection, that needle is a little bit bigger, too.”

Do IM injections last longer than IV?

Muscles are very vascular structures, and IM absorption occurs by drug diffusion from interstitial fluid and capillary membranes into plasma, and so onset of action is longer than IV injection.

What is the difference between IV and Im?

– Give to someone having an anaphylactic reaction. – Try to remember this by if someone is having an anaphylactic reaction only 1,000 people will be coming to the patient’s room. – Another way to remember this is that the concentration for IM is MORE potent (1/1,000 is a LARGER fraction) and if you are giving it IM, you will need more

Is morphine stronger then oxycodone?

There are several different kinds of opioid receptors; some research suggests that oxycodone effects more types of opioid receptors than morphine does – suggesting that it could be stronger. But different people have different levels of these receptors. If you have more of the opioid receptors that morphine acts on then morphine might be stronger.

What are the adverse effects of morphine?

Adverse Effects. Among the more common unwanted effects of morphine use is constipation. This effect occurs via stimulation of mu-opioid receptors on the myenteric plexus, which in turn inhibits gastric emptying and reduces peristalsis. Other common side effects include central nervous system depression, nausea, vomiting, and urinary retention.

How much IV morphine equals?

Morphine injections for break through pain can be safely given every 15 minutes (peak effect of IV Morphine is about 5 minutes). In this case, patient’s available breakthrough should be 60mg/ 24 hours. 2.5 mg / hr = 0.625 mg / 15 minutes: Thus the final order should read:
