1. What Caffeine Citrate 10mg/ml Solution for Injection is and what it is used for

  • Caffeine belongs to a group of medicines known as methylxanthines
  • It is used in the treatment of interrupted breathing in premature babies (primary apnoea of premature newborns).

These short periods when premature babies stop breathing are due to the baby’s breathing centres not being fully developed. This medicine has been shown to reduce the number of episodes of interrupted breathing in premature newborns.

2. What you need to know before your baby is given Caffeine Citrate 10mg/ml Solution for Injection

Your baby should not be given Caffeine Citrate 10mg/ml Solution for Injection

  • if allergic to caffeine citrate or to any of the other ingredients of this medicine listed in section 6

Warnings and precautions

  • has liver or kidney disease
  • has had any unusual heart rhythms detected or heart disease
  • suffers from seizures
  • has frequent regurgitation
  • produces more urine than usual
  • has a reduced weight gain or food intake
  • If you (the mother) consumed caffeine prior to delivery

Other medicines and Caffeine Citrate 10mg/ml solution for injection

Tell your baby’s doctor if your newborn is taking, have recently taken or might take any other medicines.

  • As with most medicines, Caffeine Citrate 10mg/ml Solution for Injection may interact with other medicines given at the same time. A premature baby may need many medicines, and any problems with caffeine are likely to be minor, but tell the doctor about any other medication they may not know about, particularly any other medicine (for example theophylline) given to your baby to help it breathe.
  • Medications containing phenobarbitone or phenytoin, taken by the mother herself to treat epilepsy, may also have an effect on the way the baby reacts to caffeine therapy. If you have been taking treatment for epilepsy during pregnancy, please tell your baby’s doctor about it.
  • Doxapram (used to treat breathing difficulties)
  • Cimetidine (used to treat gastric disease)
  • Ketoconazole (used to treat fungal infections)
  • This medicine may increase the risk for serious intestinal disease with bloody stools (necrotising enterocolitis) when administered with medicines used to treat gastric disease (such as antihistamine H2 receptor blockers or proton-pump inhibitors that reduces gastric acid secretion).

Pregnancy and breast-feeding

If you (the mother) are breast-feeding while your infant is treated with Caffeine Citrate 10mg/ml Solution for Injection, you should not drink coffee or take any other high caffeine product as caffeine passes into breast milk.

Caffeine Citrate 10mg/ml Solution for Injection contains sodium

  • Caffeine Citrate 10mg/ml Solution for Injection contains 3.04mg sodium per 1 ml of the solution, which the doctor will need to consider if your baby is on a controlled sodium diet.
  • Opening the ampoules may introduce glass particles into this solution. It is recommended that Caffeine Citrate 10mg/ml Solution for Injection be filtered before administration. Filters should not then be used to administer the dose from the syringe.

3. How Caffeine Citrate 10mg/ml Solution for Injection is used

Caffeine Citrate 10mg/ml solution for injection should only be used in a neonatal intensive care unit in which adequate facilities are available for patient surveillance and monitoring. Treatment should be initiated under supervision of a physician experienced in neonatal intensive care.

The doctor or nurse will administer Caffeine Citrate 10mg/ml Solution for Injection into a venous infusion (drip). It can also be equally effective when given by mouth, and all or some of the doses may be given this way when possible. This medicine should not be given by intramuscular injection.

The exact dose, to be determined by the doctor, depends on each baby’s needs and response to the treatment, but will usually be:

  • A starting dose of 20mg/kg of the baby’s body weight calculated as caffeine citrate (equivalent to caffeine 10mg/kg or 2ml/kg of this solution) if by injection then infused over 30 minutes
  • Followed after 24 hours by a lower daily maintenance dose of 5 to 10mg/kg of the baby’s body weight calculated as caffeine citrate (equivalent to caffeine 2.5 to 5mg/kg or 0.5 to 1ml/kg of this solution) if by injection then infused over 10 minutes

If your baby fails to respond to the starting dose (after at least 4 hours), the doctor or nurse may give one more additional starter dose, before continuing to the lower maintenance doses.

Duration of treatment

Your baby’s doctor will decide exactly how long your newborn must continue therapy with Caffeine Citrate 10mg/ml Solution for Injection. If your baby has 5 to 7 days without apnoea attacks, the doctor will stop treatment.

The doctor may decide to check the levels of caffeine in a blood sample as a precaution, or if your baby is not responding to treatment as expected.

If your baby is given more Caffeine Citrate 10mg/ml Solution for Injection than they should

If too much caffeine solution is accidentally given to your baby, the side effects described above may become more noticeable. In cases of very high overdosage, fits can also occur. If signs of over-dosage are noticed, please tell the baby’s doctor immediately.

Treatment with Caffeine Citrate 10mg/ ml Solution for Injection should be stopped immediately and your baby’s doctor should treat the overdose.

If you have any further questions on the use of this medicinal product, ask your baby’s doctor.
