Tramadol is a medication used to treat moderate to severe pain. It is an opioid analgesic that works by binding to the mu-opioid receptors in the brain and spinal cord. Tramadol is also classified as a Schedule IV controlled substance in the United States due to its potential for abuse and dependence.

Tramadol is available in immediate-release and extended-release formulations. The immediate-release form is typically taken every 4-6 hours as needed for pain relief, while the extended-release form is taken once daily. Tramadol can cause side effects such as dizziness, nausea, constipation, and headache.

It is important to use tramadol only as directed within it booklet and to not exceed the prescribed dosage. Misuse or abuse of tramadol can lead to addiction, overdose, and death. Additionally, tramadol should not be taken with certain medications, such as benzodiazepines, as this can increase the risk of respiratory depression and other serious side effects.
