Typical grounding period: 48 hours (2 days)

Guidance notes

All centrally acting muscle relaxants are sedating and slow reaction time — drowsiness, dizziness and impaired concentration are common and often unnoticed by the user. Not acceptable for aviation duty. Remain grounded until at least 24 hours (longer for long-acting agents) after the last dose and have the underlying condition assessed by a DAME.
