How to Use the Medication & Driving Safety Guide
Select your medication type and when you took it to see whether it is safe to drive, how long to wait, and important precautions. Drug-impaired driving can be as dangerous as drunk driving and carries serious legal consequences in most US states.
The FDA specifically warns that medications causing drowsiness, dizziness, blurred vision, or slowed reaction time impair driving ability. Sleep aids, opioids, first-generation antihistamines, muscle relaxants, and some antidepressants are among the highest-risk categories. Always read your prescription label and ask your pharmacist if driving is safe before starting a new medication.
