Tramadol is a prescription medication used to treat moderate to moderately severe pain. It is classified as an opioid analgesic, but it also has non-opioid properties due to its dual mechanism of action, which involves inhibiting the reuptake of serotonin and norepinephrine. Tramadol can be associated with side effects and carries a risk of dependence, so it should be used under medical supervision. It is available in various forms, including tablets and extended-release formulations.
