Oxycodone is a type of strong painkiller known as opioid or opiate. This is used pain o relieve severe pain associated with cancer or severe injury. The Food and Drug Administration (FDA) has already approved this medication

Cancer is caused by changes in DNA within cells. The DNA inside a cell is packaged into a large number of individual genes. Each of which contains a set of instructions telling the cell what functions to perform and how to grow and divide. Errors in the instructions can cause the cell to stop its normal function and may allow a cell to become cancerous. Cancer refers to any one of a large number of diseases characterized by the development of abnormal cells that divide uncontrollably and have the ability to infiltrate and destroy normal body tissue. This often can spread throughout your body. Cancer is the second-leading cause of death in the world. But survival rates are improving for many types of cancer, thanks to improvements in cancer screening and cancer treatment. Signs and symptoms caused by cancer will vary depending on what part of the body is affected. Some general signs and symptoms associated with, but not specific to, cancer include:

  • Weight changes
  • Fatigue
  • Persistent cough or trouble breathing
  • Lump or area of thickening that can be felt under the skin
  • Skin changes such as darkening, yellowing, or redness of the skin, changes to existing moles, or sores that won’t heal,
  • Changes in bowel or bladder habits
  • Hoarseness
  • Difficulty swallowing
  • Persistent and unexplained fevers or night sweats
  • Persistent and unexplained muscle or joint pain
  • Persistent indigestion or discomfort after eating
  • Unexplained bleeding or bruising 

Injuries can be caused by accidents or acts of violence. It may occur at work, home, or play. They can be due to impact from blunt objects or from objects that penetrate the body. Injuries can be minor or severe. Minor injuries can often be managed with basic first aid techniques. Major injuries may require medical intervention or evaluation in an emergency setting. In some cases, a seemingly minor injury may be a major injury requiring more urgent medical attention. Your doctor will also determine if an underlying medical condition was responsible. Treatment of injury depends upon the type and severity. Serious injury can lead to permanent disability and may be life-threatening. Injury symptoms vary depending on the type and severity of the injury itself. Injuries range from minor cuts bruises and scrapes to large, severe burns, open wounds, and blunt force resulting in unconsciousness. 

How does the medicine work? 

Opioids work by imitating the action of natural pain-reducing compounds called endorphins. These are produced in the brain and spinal cord. Oxycodone acts on the same opioid receptors as our natural endorphins. It stops pain signals being sent by the nerves to the brain. This means that even though the cause of the pain may remain, less pain is felt. This medicine is similar to morphine in effectiveness and side effects.

This is addictive when used recreationally. But in reality, if you’re taking Oxycodone to relieve pain it’s highly unlikely that you will get addicted to it in the psychological sense. It is because you’re not taking it to get high. If you need to take Oxycodone for long periods your body can become tolerant of it, so it may get less effective and you may then need higher doses to control pain. With prolonged use, it is possible to become dependent on this medicine. However, this is not usually a problem when you stop taking it, because withdrawal symptoms can be avoided by reducing treatment gradually. You mustn’t take a higher dose of Oxycodone than prescribed by your doctor or take it for longer than they recommend. When stopping treatment always follow your doctor’s instructions.
