Which statement best describes Class 4 medications in the aeromedical context?

• A. They require a waiver before flight
• B. They lead to mandatory disqualification
• C. They can be used with medical clearance
• D. They have no impact on flight eligibility

Answer: (B)

Class 4 medications are treated as disqualifying because they pose a significant safety risk or indicate a condition that makes flying unsafe. Under this classification, pilots are grounded while on the drug, and there isn’t a routine pathway for flight clearance with these medications in place. Only after the medication is stopped and a medical evaluation shows no impairment could eligibility be reconsidered. This is why the statement that best describes Class 4 medications is that they lead to mandatory disqualification.
