1. What is Gencebok and what is it used for
Gencebok contains the active substance caffeine citrate, which is a central nervous system stimulant belonging to a group of medicines called methylxanthines.
Gencebok is used to treat apnea of prematurity (primary apnea of premature infants).
These brief periods during which premature infants stop breathing are due to the fact that the child's respiratory center is not fully developed.
It has been observed that this medicine reduces the number of episodes of apnea in premature infants.
2. What you need to know before your child starts treatment with Gencebok
Do not use Gencebok:
- if your newborn is allergic to caffeine citrate or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Consult your child's doctor before starting treatment with Gencebok.
Before starting treatment for apnea of prematurity with Gencebok, your child's doctor should have ruled out or adequately treated other causes of apnea.
Gencebok should be used with caution. Inform your child's doctor:
- If your child has a history of seizures
- If your child has heart disease
- If your child has kidney or liver problems
- If your child has frequent regurgitation
- If your child produces more urine than normal
- If your child does not show sufficient weight gain or does not eat enough
- If you (the mother) consumed caffeine before birth
Using Gencebok with other medicines
Tell your child's doctor if they are taking, have recently taken, or might take any other medicines.
Tell your child's doctor if they have been previously treated with theophylline.
Do not use the following medicines during treatment with Gencebok without talking to your child's doctor first. The doctor may need to adjust the dose or change one of the medicines to another:
- theophylline (used to treat breathing difficulties)
- doxapram (used to treat breathing difficulties)
- cimetidine (used to treat stomach diseases)
- ketoconazole (used to treat fungal infections)
- phenobarbital (used to treat epilepsy)
- phenytoin (used to treat epilepsy)
This medicine may increase the risk of severe intestinal disease with bloody stools (necrotizing enterocolitis) when given with certain medicines used to treat stomach diseases (such as H2 receptor antagonists or proton pump inhibitors that reduce gastric acid secretion).
Pregnancy and breastfeeding
If you (the mother) are breastfeeding while your child is being treated with Gencebok, you should not drink coffee or take other products with high caffeine content, as caffeine passes into breast milk.
Gencebok contains sodium
This medicine contains less than 1 mmol (23 mg) of sodium per dose, so it can be considered as essentially sodium-free.
3. How to use Gencebok
Gencebok should only be used in a neonatal intensive care unit with adequate facilities for patient observation and monitoring. Treatment should be initiated under the supervision of a doctor with experience in neonatal intensive care.
Dose
Your child's doctor will prescribe the correct amount of Gencebok based on your child's weight. The initial dose is 20 mg per kg of body weight (equivalent to 2 ml per kg of body weight). The maintenance dose is 5 mg per kg of body weight (equivalent to 0.5 ml per kg of body weight) every 24 hours.
Method and route of administration
Gencebok should be administered by controlled intravenous infusion using a infusion pump with a syringe or other volumetric infusion device. This method is also known as "drip" infusion.
Some doses (maintenance doses) may be given orally.
It may be necessary for your child's doctor to monitor caffeine levels through periodic blood tests throughout treatment to avoid toxicity.
Duration of treatment
Your child's doctor will decide exactly how long your child should be treated with Gencebok. If your child remains apnea-free for 5 to 7 days, the doctor will discontinue treatment.
If your child receives more Gencebok than they should
Your child may experience fever, rapid breathing (tachypnea), nervousness, muscle tremors, vomiting, elevated blood sugar levels (hyperglycemia), decreased potassium levels in the blood (hypokalemia), elevated levels of certain chemicals in the blood (urea), and increased white blood cell count, as well as seizures if they receive more caffeine citrate than they should.
In these cases, treatment with Gencebok should be discontinued immediately and your child's doctor will need to treat the overdose.
If you have any other questions about the use of this medicine, ask your child's doctor.
