What a Special Issuance is
The Guide says an Authorization for Special Issuance, valid for a specified period, may be granted at the Federal Air Surgeon's discretion to a person who does not meet the established medical standards, if the person shows to the satisfaction of the Federal Air Surgeon that the duties authorized by the class of certificate applied for can be performed without endangering public safety during the period the Authorization would be in force.
How the FAA pathways workGood to know
Points from the FAA's own documents that are easy to miss.
What a progress note must include
In most cases it should come from a visit with the treating physician no more than 90 days ago, and cover the history, medications with dosages and side effects, exam findings, test results, diagnosis, assessment and plan, prognosis and follow-up. The FAA's sheet says to make sure the physician adds the prognosis. A portal note or an After Visit Summary that does not meet these criteria is not enough, and neither is a simple "ok to fly" letter. The FAA's documents also call it a status report.

your patient portal to print out “notes” or an “After Visit Summary (AVS).” … Patient Portal notes or an AVS that do not meet the criteria listed below for a detailed Clinical Progress Note are NOT sufficient for FAA purposes. … To be “current,” in MOST CASES, the detailed Clinical Progress Note should be from an evaluation in which you saw your treating physician no more than 90 days ago. … It Must include the following items: … A summary of the history of the condition, … Current medications, dosages, and side effects (if any); … Clinical exam findings; … Results of any testing performed; … Diagnosis; … Assessment and Plan; … Prognosis (This item may not be on a standard progress note, make sure your physician adds this information.); and … Follow-up … Please note: A letter stating, “Mr. Smith is ok to fly” (or any other simple note), is NOT a current, detailed Clinical Progress Note and is NOT acceptable. … You may also see this called a “current status report” or “status report” in current FAA Guidance. Any reference to a “status report” equals the criteria listed on this sheet.
Sacrosidase (Sucraid) and a waiting period
The table names no waiting period after starting a medication. The FAA's MedGuide lists sacrosidase (Sucraid) as allowed, for CSID, with a wait of 7 days after the first dose. Check a medication shows both documents.
