Morphine is one of the most commonly prescribed opioids for managing moderate to severe pain. The 30mg tablet form is used when other painkillers are not sufficient. It works by blocking pain signals in the brain, offering relief to patients suffering from conditions such as cancer or post-surgical pain. While effective, morphine has a high potential for misuse, addiction, and overdose. Over time, individuals may develop a tolerance, requiring higher doses to achieve the same level of relief. Side effects of morphine include nausea, drowsiness, and constipation. It should only be used under strict medical supervision to avoid risks.
