Usage of Lofexidine

Lofexidine works by blocking the release of norepinephrine, a hormone similar to adrenaline that contributes to opioid withdrawal symptoms.

Lofexidine is a non-opioid prescription medicine used in adults to help with the symptoms of opioid withdrawal that may happen when you stop taking an opioid suddenly.

Lofexidine will not completely prevent the symptoms of opioid withdrawal, which may include feeling sick, stomach cramps, muscle spasms or twitching, feeling of cold, heart pounding, muscular tension, aches and pains, yawning, runny eyes and sleep problems (insomnia).

Lofexidine will not treat opioid addiction. If you have been diagnosed with opioid addiction, your healthcare provider may prescribe this medicine as part of a complete treatment program for your opioid use disorder.
