Cafcit Dosage

Generic name: CAFFEINE CITRATE 20mg in 1mL
Dosage form: injection

Medically reviewed on March 12, 2018.

Prior to initiation of CAFCIT (caffeine citrate), baseline serum levels of caffeine should be measured in infants previously treated with theophylline, since preterm infants metabolize theophylline to caffeine. Likewise, baseline serum levels of caffeine should be measured in infants born to mothers who consumed caffeine prior to delivery, since caffeine readily crosses the placenta.

The recommended loading dose and maintenance doses of CAFCIT follow.

Dose of CAFCIT (caffeine citrate) Volume

Dose of CAFCIT (caffeine citrate) mg/kg



Loading Dose

1 mL/kg

20 mg/kg

Intravenous* (over 30 minutes)

One time

Maintenance Dose

0.25 mL/kg

5 mg/kg

Intravenous* (over 10 minutes) or Orally

Every 24 hours**

*using a syringe infusion pump
**beginning 24 hours after the loading dose

NOTE THAT THE DOSE OF CAFFEINE BASE IS ONE-HALF THE DOSE WHEN EXPRESSED AS CAFFEINE CITRATE (e.g., 20 mg of caffeine citrate is equivalent to 10 mg of caffeine base).

Serum concentrations of caffeine may need to be monitored periodically throughout treatment to avoid toxicity. Serious toxicity has been associated with serum levels greater than 50 mg/L.

CAFCIT should be inspected visually for particulate matter and discoloration prior to administration. Vials containing discolored solution or visible particulate matter should be discarded.

Drug Compatibility

To test for drug compatibility with common intravenous solutions or medications, 20 mL of CAFCIT Injection were combined with 20 mL of a solution or medication, with the exception of an Intralipid® admixture, which was combined as 80 mL/80 mL. The physical appearance of the combined solutions was evaluated for precipitation. The admixtures were mixed for 10 minutes and then assayed for caffeine. The admixtures were then continually mixed for 24 hours, with further sampling for caffeine assays at 2, 4, 8, and 24 hours.

Based on this testing, CAFCIT Injection, 60 mg/3 mL is chemically stable for 24 hours at room temperature when combined with the following test products.

• 50% Dextrose Injection USP

• Intralipid® 20% IV Fat Emulsion

• Aminosyn® 8.5% Crystalline Amino Acid Solution

• Dopamine HCI Injection, USP 40 mg/mL diluted to 0.6 mg/mL with Dextrose Injection, USP 5%

• Calcium Gluconate Injection, USP 10% (0.465 mEq/Ca+2/mL)

• Heparin Sodium Injection, USP 1000 units/mL diluted to 1 unit/mL with Dextrose Injection, USP 5%
