Patient Education

Lofexidine


Lofexidine is used to manage opioid withdrawal symptoms (e.g., sick feeling, stomach cramps, muscle spasms or twitching, cold sensation, heart pounding, muscle tension, aches and pains, yawning, runny eyes, or difficulty falling asleep or staying asleep) that may occur after an opioid medication is suddenly stopped. Lofexidine is in a class of medications called central alpha adrenergic agonists. It works by relaxing blood vessels so that blood can flow more easily through the body.
