Morphine is an opioid analgesic. It is often used to relieve moderate to severe pain as well as to treat moderate to severe chronic pain.
Morphine is typically used for pain management after surgery, during labor, and for post-surgical pain in addition to palliative care. It may also be used prior to or after major surgery. Morphine can be given by injection, by mouth (by mouth), or by a transdermal patch (on the skin).
Morphine works on the nervous system by blocking the nerves that are affected by morphine. This helps reduce or eliminate the sensation of pain.Opioid analgesics include heroin, codeine, morphine and other similar drugs.
What it is Used for:
Morphine is used as an analgesic (pain reliever) or sedative (sleep aid). It reduces spasms caused by intense muscle stiffness and also helps ease moderate to severe pain. It’s also used in some surgeries because it can help reduce stress caused by severe pain medication.
Morphine is a narcotic analgesic used to relieve moderate to severe pain. This can lead to relief from pain, which can last from 30 minutes up to several hours. When taken as a short-acting premedication (a few hours before surgery or other medical procedures) or in high doses, it also acts as an anaesthetic and causes sedation or respiratory depression.
How long does it take to work?
The effect of morphine starts within 10 minutes of taking the medicine and lasts up to four hours depending on how much you have taken. The effects usually last longer if they are taken at regular intervals. You might feel drowsy when you first take this medicine but this should pass within half an hour after your dose has been taken so that you can drive safely if required
Within 10 minutes of taking a tablet of morphine, you’ll start to feel the effects. After that, it takes around 10-15 minutes for the effects to kick in and another 10-15 minutes for them to wear off completely.
The average dose of morphine per day is between 2-6mg per day (2-6mg every four hours), but doses can vary depending on the patient’s physical condition, history and tolerance level. The maximum recommended daily dose is 5 mg/day (5mg every four hours).
What are the potential side effects of morphine?
All opioids, including morphine, can have life-threatening adverse effects, including respiratory issues. These are more dangerous:
If you are older and have an existing lung condition when you first start taking morphine after a dosage increase
Morphine’s other side effects are comparable to those of other opioids, and these include:
- Slow heart rate (bradycardia)
- Blood pressure that is too low
- Dilated or ‘pin-point’ pupils, nausea, vomiting
- Shallow, slow breathing
Because morphine has varied effects on different people, talk to your pharmacy or doctor if you feel like the drug is making you feel sick or if your pain is not being sufficiently controlled while you are taking it.
Take medications exactly as directed by your doctor.
