Uses for indomethacin

Indomethacin injection is used to treat patent ductus arteriosus (PDA) in premature infants (babies born too early) who weigh between 500 and 1750 grams. PDA is a heart problem where a blood vessel, the ductus arteriosus, does not close normally after birth. This blood vessel is only needed before birth, and is no longer necessary after the baby is born. Indomethacin injection works by causing the PDA to constrict, which closes the blood vessel. This medicine is used when other medical treatments for PDA do not work after 48 hours.

This medicine is available only with your doctor's prescription.

Precautions while using indomethacin

Indomethacin injection may change how the body reacts during an infection. Your baby's doctor will monitor your baby for any signs of infection (e.g., fever, chills, or other unusual behavior).

This medicine may affect how platelets work, which are necessary for blood clotting. This may increase the chance of bleeding for your baby. Your baby's doctor will watch for any unusual bleeding or bruising, dark-colored urine or stools, or other signs of bleeding in your baby.

This medicine may lower your baby's urine output. This may raise your baby's risk of kidney problems or low sodium in the blood (hyponatremia). Blood and urine tests will be needed to look for any signs of these risks.

Liver problems may happen while your baby is receiving this medicine. Stop using this medicine and contact your baby's doctor right away if your baby has more than one of these symptoms: abdominal pain or tenderness; clay-colored stools; dark urine; decreased appetite; fever; headache; itching; loss of appetite; nausea and vomiting; skin rash; swelling of the feet or lower legs; unusual tiredness or weakness; or yellow eyes or skin.

Do not take other medicines unless you have discussed them with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
