DESCRIPTION
Tramadol is an analgesic that is related to the opioids. While its mode of action resembles that of narcotics and it is as effective as many narcotics in relieving pain, it is not a narcotic and does not depress breathing, a side effect of most narcotics.
Tramadol is also not a nonsteroidal anti-inflammatory drug (NSAID) and does not have the increased risk of stomach ulceration and internal bleeding that can occur with the use of NSAIDs.
It does affect serotonin neurotransmitters — chemical messengers — in the brain that may help change the perception of pain in diabetic neuropathy.

NEWLY DISCOVERED USES (OFF-LABEL)

See recommendation above regarding consultation with doctor or pharmacist.

Two key studies have demonstrated the efficacy and safety of tramadol in diabetic neuropathy. A clinical study in 131 diabetes patients showed a significant reduction in pain intensity compared to placebo, according to
Neurology.
A second study compared tramadol to placebo for the treatment of pain, paresthesia, and touch-evoked pain associated with polyneuropathies. The drug again proved to be more effective than placebo, although the improvement was modest, according to
Pain.
An article in the
American Journal of Health System Pharmacists concluded that tramadol is safe and effective for diabetic neuropathy, although the dose required for benefits is relatively high.
