How Long Should You Wait to Drive After Taking Carisoprodol?
Half-Life of Carisoprodol:
Carisoprodol has a half-life of ~2 hours, but its active metabolite, meprobamate, has a much longer half-life (6–17 hours).
This means effects may last:
4 to 6 hours for minor sedation
Up to 24 hours for residual drowsiness and sluggishness
Risk of DUI (Driving Under the Influence)
Legal Consequences:
Even though Carisoprodol is a prescription drug, driving under its influence can result in:
DUI/DWI charges
Fines or license suspension
Arrest if an accident occurs
What the Law Says:
In many countries and U.S. states:
If you're "impaired to any degree" while driving, even from prescription meds, you're legally liable
You're expected to know your medication's effects
So yes, you can get a DUI for driving on Carisoprodol.
