Uses for Cafcit

Caffeine tablets are used to help you stay awake when you feel drowsy or unusually tired or weak. Do not use this medicine instead of getting sleep.

Caffeine oral solution is used to treat short-term apnea of prematurity when premature babies (infants between 28 and 32 weeks gestational age) stop breathing. Apnea of prematurity happens because the baby's breathing centers are not fully developed.

This medicine is available with or without a doctor's prescription.

Precautions while using Cafcit

Your doctor will closely monitor your progress while you or your child are using this medicine. This will help your doctor determine if the medicine is effective and if you should continue to use it.

If you are using caffeine solution:

  • Call your baby's doctor immediately if your baby continues to have apnea.

  • Contact your baby's doctor immediately if your baby experiences any of the following symptoms: abdominal or stomach swelling, vomiting, or bloody stools. These may indicate a serious bowel or stomach issue.
  • Do not adjust your baby's dose without first consulting your baby's doctor.
