Every medicine has its side effects, so what are those of pain medications? Side effects vary with different kinds of painkillers.
Different medications are given depending on the levels of pain. The most commonly used medications for post-surgical pain include: Acetaminophen (Paracetamol), Nonsteroidal anti-inflammatory drugs (NSAIDs) and Opioids. Acetaminophen (Paracetamol), also known as Panadol, when taken too much can cause liver damage, and can also lead to stomach and kidney related side effects. Opioids are the most powerful of these drugs, they can also cause nausea, vomiting, bloating, urinary retention, itchiness and are also addictive. Taking large amounts can also stop your breathing. Most pain medications are controlled drugs. For postsurgical pain, all you need is to follow the doctor’s prescription for pain medications. If side effects occur, doctors will prescribe other drugs to reduce it. As long as you follow the instructions and ask the doctor if you have questions and concerns, the pain will be well managed and you will have less side effects.
