Side effects of opioids

Buymedsuk Online Pharmacy FAQ
Opioids, sometimes called narcotics, are medications prescribed by doctors to treat persistent or severe pain. They are used by people with chronic headaches and backaches, by patients recovering from surgery or experiencing severe pain associated with cancer, and by adults and children who have gotten hurt playing sports or who have been seriously injured in falls, auto accidents or other incidents. How do opioids work? Opioids attach to proteins called opioid receptors on nerve cells in the brain, spinal cord, gut and other parts of the body. When this happens, the opioids block pain messages sent from the body through the spinal cord to the brain. While they can effectively relieve pain, opioids carry some risks and can be highly addictive. The risk of addiction is especially high when opioids are used to manage chronic pain over a long period of time.
