Guidance for medical examiners when assessing a patient for either a general topic or condition - Medication.

  • This guidance applies to all drugs, whether herbal, over-the-counter or prescription
  • Just because a medication is available over-the-counter doesn’t mean it is automatically safe in aviation
  • All medications are considered hazardous; specific exceptions are listed below
  • Inclusion in the 'Approved List' does not mean these medications are without hazard. In case of any concern, medical advice must be sought
  • Starting a medication or changing a dose up or down is a “Change in medical condition” (See CASR Part 67 definition) and must be reported to your DAME or CASA within 5 days if lasting for more than:
  • Class 1: 7 days
  • Class 2 and 3: 30 days
  • For all treatments, the safety-relevance of the condition as well as medication must be considered; e.g. the condition being treated must be considered as well as any treatment used
  • Some treatments e.g. desensitisation for allergies, hormone injections for cancer of the prostate, may be single injections which last for extended periods of time. You must check with your DAME or CASA if this is a safety-relevant treatment.
