Ultram, also known by its generic name tramadol, is a prescription medication primarily used to relieve moderate to moderately severe pain. It belongs to a class of drugs called opioid analgesics, which work by binding to opioid receptors in the brain and spinal cord, thus altering the perception of pain. Ultram is commonly prescribed for conditions such as postoperative pain, chronic pain, and pain associated with injuries. It is available in various formulations, including immediate-release and extended-release tablets. It's essential to use Ultram as directed by a healthcare professional, as it can be habit-forming and may cause withdrawal symptoms if discontinued abruptly.
