Products Affected - Description

• • Anectine injection, Sandoz, 20 mg/mL, 10 mL vial, 10 count, NDC 00781-3009-95

Reason for the Shortage

• • Hospira has a consistent supply of Quelicin injection.[1]
  • Sandoz discontinued Anectine in September 2015.[2]

Available Products

• • Quelicin injection, Pfizer, 20 mg/mL, 10 mL vial, 25 count, NDC 00409-6629-02

• • All marketed presentations are currently available.

• • Succinylcholine chloride injection is a depolarizing neuromuscular blocking agent and is typically a drug of choice for short procedures (3 minutes or less).[3,4]

• • Clinicians must use extreme caution if a different strength is used. Clinicians may elect to use an alternative agent rather than risk a 5-fold overdose or underdose.
  • Ensure supplies of succinylcholine are reserved for critical uses.

• • During this shortage, clinicians should reserve supplies of succinylcholine for procedures where succinylcholine is the agent of choice.
  • Centers should make any operational changes necessary so that supplies of succinylcholine do not become outdated because of room temperature storage.
  • Alternative NMBAs vary in onset time and duration of action, particularly based on dose; see the table below. Times to re-dose also differ based on agent and dose. Doxacurium, mivacurium, and tubocurarine have been discontinued.[3,4,5]
  • Non-depolarizing neuromuscular blocking agents may be reversed with neostigmine or edrophonium. Depolarizing NMBAs (ie, succinylcholine) are not reversed by these agents and their toxicity may be worsened by concomitant administration.[3,4,5]
