Other groups of medications

Every medication Crosscheck has an FAA answer for, by group or from A to Z, with the answer and the wait on each line. New from the FAA in October 2026: the FAA's MedGuide, explained.

Medication guidance alone does not determine whether a pilot is medically qualified to fly. The underlying condition, dosage, side effects, medication combinations, and certification history may affect FAA eligibility.
