Testing a numbing medication to reduce pain drug use in sickle cell crisis

This trial is testing lidocaine—a numbing medication commonly used in medicine—to see if it can help reduce how much opioid pain medication people need when they experience a severe vaso-occlusive crisis (a sudden, intense pain episode caused by sickle cell disease). Half of the participants will receive lidocaine along with their regular pain treatment, while the other half will receive a placebo (a saltwater solution that looks the same) along with their regular pain treatment. Researchers want to find out if this medication can help manage pain while lowering opioid use.

Sickle cell disease causes severe, unpredictable pain crises that currently require high doses of opioid medications to manage. Because opioids carry serious risks—including addiction and other side effects—doctors need new ways to control pain without relying so heavily on these drugs.
