Obtain instructions for the actual procedure

Ask the clinician to distinguish effects from cell collection, administration, the preparation and other medicines. Obtain a written contact and escalation plan for after you leave the facility. Report new symptoms using the treatment date and product details rather than assuming discomfort is a sign that the procedure is working.

Questions to take to a consultation

  • Which effects are expected and for how long?
  • Which symptoms need urgent assessment?
  • Who will review a concern after I return home?

Request clear written answers and discuss unresolved points with a clinician familiar with your history before committing to a product or procedure.
