Morphine is a strong opioid analgesic used to treat moderate to severe pain.
It is commonly indicated for post-operative pain, severe injuries, and visceral pain of various origins,
including myocardial infarction or heart attack, acute pancreatitis, acute cholecystitis, etc.
While morphine can be highly effective, it can also cause several adverse effects, including the following.
Drowsiness. Morphine commonly causes sleepiness and reduced alertness.
Therefore, it is important to avoid driving or operating machinery while taking it.
Nausea and vomiting. These are common, especially when starting treatment,
but often improve as the body adjusts to the medication.
Constipation. This is one of the most frequent side effects of morphine.
Drinking plenty of fluids, eating a high-fiber diet, and sometimes using a laxative may help.
Dizziness and low blood pressure. Some people may feel lightheaded, particularly when standing up quickly.
Itching. Morphine can trigger the release of histamine, causing itching or flushing in some individuals.
Respiratory depression. This is the most serious side effect.
Morphine can slow breathing, particularly at high doses or when combined with alcohol or other sedative medications.
Seek emergency medical attention if breathing becomes slow or difficult.
