Caffeine and Sodium Benzoate Injection Shortage
Last Updated: November 7, 2016
- American Regent could not provide a reason for the shortage of caffeine and sodium benzoate injection.
- American Regent is the sole manufacturer of caffeine and sodium benzoate injection.
- Caffeine, anhydrous (125 mg/mL) / Sodium benzoate (125 mg/mL) injection, American Regent, 2 mL single dose vial, 10 count, NDC 00517-2502-10
Estimated Resupply Dates
- American Regent has caffeine and sodium benzoate 2 mL vials available.
Implications for Patient Care
- Caffeine and sodium benzoate is labeled for the treatment of acute respiratory depression associated with overdosage of CNS depressant agents, although it is no longer a preferred agent for this indication.[2,3,4] Caffeine and sodium benzoate is more commonly used off-label for the treatment of postdural puncture headache and in combination with electroconvulsive therapy (ECT) to prolong seizure duration.[2,4]
- Do not interchange caffeine citrate with caffeine and sodium benzoate. Caffeine citrate is labeled for the treatment of idiopathic apnea of prematurity.[2,4]
Alternative Agents & Management
- Data are limited describing alternative pharmacologic therapies for postdural puncture headache and ECT seizure prolongation. Oral caffeine solution is not affected by the shortage and may be used for treating postdural puncture headache. Intravenous aminophylline, intravenous theophylline, and oral theophylline have been used with ECT in small clinical trials to prolong seizure duration. The Table includes potential alternatives for ECT and postdural puncture headaches.
Table 1. Selected Clinical Uses of Caffeine and Sodium Benzoate and Potential Therapeutic Alternatives Indication Treatment of Choice Alternatives Comments Postdural Puncture Headache2,5,6,7,8,9,10 Caffeine and Sodium Benzoate 500 mg in 1,000 mL normal saline infused over 1 hour, followed by 1,000 mL normal saline infused over 1 hour.
A second dose may be given after 4 hours if necessary.
Oral caffeine solution 300 mg as a single dose.
Epidural sodium chloride 0.9% 24 hour infusion or 20-30 mL injection.
Conservative measures such as bed rest, analgesics, and oral hydration are recommended for the first 24-48 hours. An epidural blood patch is a treatment option for severe headaches or if conservative measures fail.
The effects of both intravenous and oral caffeine are transient and the headache may return.
Electroconvulsive Therapy2,11,12,13,14,15,16,17 Caffeine and Sodium Benzoate 500 mg (maximum of 2000 mg) intravenous infused over 20-30 seconds 5 minutes prior to electrical stimulation. Aminophylline 3-5 mg/kg intravenous 10 minutes prior to electrical stimulation
Theophylline 200-400 mg sustained-release tablets orally 10 hours prior to electrical stimulation13,15,17
Theophylline injection 100-200 mg intravenous over several minutes, given 30 minutes prior to electrical stimulation16
Theophylline may cause status epilepticus in patients with slightly higher than therapeutic plasma concentrations.
