Administration of caffeine citrate depends on the age of the patient, condition being treated, and the form of medication prescribed.

Caffeine Citrate Injection: The injection is given by a health care provider in a hospital or clinic. It may be given intravenously (IV) or intramuscularly (IM).

Neonates: Administration for preterm neonate involves loading dose of caffeine citrate at 20 mg/kg is given along with a continuation dose that is typically 5-10 mg/kg/day administered once daily.

Adult: Caffeine citrate infusion is also administered in adults as a continuous infusion in some cases.

Caffeine Citrate Oral Liquid: The oral liquid preparation is mostly administered in the outpatient department. It is dosed based on the patient’s weight and clinical needs. The dosage of this preparation is often in small, frequent dosing as compared to the injectable.

Neonates/Infants: The oral liquid preparation is sometimes used for the longer term management of apnea of prematurity with the dose adjusted according to the infant’s response and weight.

It is advisable to strictly follow the instructions of the healthcare provider on the dosage and administration to avoid complications or overdosing.

Caffeine citrate acts through stimulation of the CNS but is mainly addressed towards the respiratory centers in the brain. This is by inhibition of adenosine receptors that stimulate sleep and relaxation; blocking the receptors increases the release of dopamine and norepinephrine, all of which stimulates alertness, energy, and respiratory drive.

Apnea of prematurity: This is a condition where premature babies experience intermittent cessation of breathing due to immature respiratory control centers in the brain. Caffeine citrate stimulates the respiratory centers in the brainstem, increasing the rate and depth of breathing. This helps reduce the frequency of apnea episodes and promotes more regular breathing patterns.

In Adults: In adult patients, caffeine citrate can be CNS stimulant that enhances alertness and reduces fatigue. It also has mild vasoconstrictive effects that may improve blood flow and increase blood pressure in some individuals.

As with any medication, caffeine citrate can cause side effects, especially if the dosages are too high or when it is not used as prescribed.

Common Side Effects

Irritability or jitteriness (especially in infants)

Tachycardia or rapid heart rate

Nausea or vomiting

Serious Side Effects

Seizures: High doses of caffeine citrate can cause seizures, especially in neonates or those with other health problems.

Arrhythmias: Caffeine citrate can induce arrhythmias, especially in patients with pre-existing heart disease.

Overuse: Overuse or inadequate dosing of caffeine citrate leads to caffeine toxicity, presenting symptoms that include jitteriness, seizures, and abnormal heart rhythms. Dosing should always be followed to the letter.

Preterm infants: Caffeine citrate does exerts a therapeutic effect in the treatment of apnea in premature infants, but with dose watched carefully for jitteriness or seizures.

Drug Interactions: Caffeine citrate may interact with other drugs, such as antidepressants, antipsychotics, and drugs that alter heart function or blood pressure. Always make known the concomitant drugs that a patient is receiving.

CYP1A2 Inhibitors: Caffeine citrate is metabolized by CYP1A2, so drugs like fluvoxamine or ciprofloxacin that inhibit this enzyme can increase caffeine levels, leading to enhanced side effects such as jitteriness, tachycardia, or insomnia.

Other Stimulants: Combining caffeine citrate with other stimulants, such as amphetamines or theophylline, may increase the risk of cardiovascular effects like hypertension or arrhythmias.

Anticonvulsants: Medications like phenytoin can accelerate caffeine metabolism, reducing its therapeutic effects.

Antidepressants: Some antidepressants, particularly SSRIs and SNRIs, may increase the risk of serotonin syndrome when combined with caffeine, especially at higher doses.

Neonates (for Apnea of Prematurity):

Loading Dose: A common initial infusion of caffeine citrate is 20 mg/kg, intravenous or intramuscularly, often over a 30-minute infusion period.

Maintenance Dose: Following the loading dose, a maintenance dose of 5-10 mg/kg/day is usually administered once daily, with dosing adjusted according to the infant’s weight, gestational age, and clinical response.

In Adults:

General Dosing: In adults, caffeine citrate is used at lower doses for conditions such as fatigue or mild respiratory stimulation. Dosing is tailored to the clinical situation and response to treatment.

Caffeine citrate is a prescription-only drug and must be ordered from a licensed healthcare professional due to the potential for side effects, drug interactions, and the necessity for careful monitoring, especially in neonates and infants. 

Healthcare professionals will evaluate the patient’s condition, weight, and clinical need to determine the appropriate dosage and route of administration.

General Information

1. What is caffeine citrate and what is it used for?

   • Caffeine citrate is a medication that contains caffeine and is primarily used to treat apnea of prematurity in premature infants. It acts as a central nervous system stimulant to help regulate breathing.

2. In what forms is caffeine citrate available?

   • Caffeine citrate is available as an oral liquid and injectable formulation, allowing for flexibility in administration depending on the clinical situation.

Mechanism of Action

3. How does caffeine citrate work in the body?

   • Caffeine citrate stimulates the central nervous system by blocking the actions of adenosine, which promotes wakefulness and stimulates respiratory drive, helping prevent pauses in breathing.

4. What is the significance of using citrate as a salt form of caffeine?

   • Caffeine citrate is more soluble and is tolerated better in infants, allowing for effective administration while reducing the risk of overdose compared to caffeine alone.

Dosage and Administration

5. What is the typical dosage for caffeine citrate in premature infants?

   • The initial dose usually depends on the infant’s weight, often starting with 20 mg/kg, with maintenance doses typically ranging from 5 to 10 mg/kg, administered once daily.

6. How is caffeine citrate administered via injection?

   • The injectable form is typically administered intravenously by a healthcare professional in a clinical setting, ensuring safe and effective delivery into the bloodstream.

7. How is the oral liquid form of caffeine citrate used?

   • The oral liquid is given directly into the infant’s mouth, usually via a syringe or dropper, and is often used for longer-term management of apnea.

Side Effects

8. What are the common side effects of caffeine citrate?

   • Common side effects may include irritability, jitteriness, feeding intolerance, and increased heart rate. Most side effects are mild and resolve as the infant acclimates to treatment.

9. Are there any serious side effects associated with caffeine citrate?

   • Serious side effects are rare but can include significant heart rate changes, seizures, or severe allergic reactions. Immediate medical attention should be sought if these occur.

Precautions and Contraindications

10. Who should avoid using caffeine citrate?

    • Caffeine citrate should be used cautiously in infants with a history of hypersensitivity to caffeine or those with certain cardiovascular conditions.

11. What precautions should be taken before administering caffeine citrate?

    • Healthcare providers should assess the infant’s overall health, including any existing medical conditions and medications, to avoid potential interactions or complications.
