  • Refills of medication before you run out
  • Shipment of medication supplies, such as caps or syringes
  • 24/7 on-call pharmacist support
  • Specialized UCD training and support

Whether something is missing or broken, your shipment is late, or you have a question about what you received, TranscendRare will work closely with the specialty pharmacy to get you what you need. Call your patient advocate with any concerns related to your urea cycle disorder medication shipments.
