RESADOL is a combination medication that typically includes Paracetamol (Acetaminophen) and Codeine, which is used for the relief of moderate to severe pain. Paracetamol acts as an analgesic and antipyretic, helping to reduce pain and fever by blocking certain chemicals in the brain. Codeine, an opioid analgesic, works by altering the way the brain and nervous system respond to pain, providing additional pain relief. RESADOL is commonly prescribed for conditions like post-surgical pain, injury-related pain, or chronic pain that does not respond to non-prescription pain relievers. Due to the presence of Codeine, the medication may cause side effects such as drowsiness, constipation, or dizziness, and there is a risk of dependence if used for prolonged periods. It should be used only as prescribed by a healthcare provider, and caution is advised for individuals with a history of substance abuse or respiratory issues.
