The finding
PORK

Curosurf is a lung surfactant made from pig lung. This is the medicine itself. It is given to premature babies whose lungs cannot yet stay open on their own.

This medicine can save a premature baby's life. The decision to use it belongs to the NICU team alone. Scholars have long recognized necessity where a child's life is at stake; bring any question to a scholar you trust.
We tell you the source. Your scholar decides what's permissible, and your doctor and pharmacist decide your care.

What this means

Curosurf is a lung surfactant; it helps the lungs stay open. No plant or synthetic lung surfactant is available in the US; every available surfactant comes from animal lung. Curosurf is pig-derived; Survanta and Infasurf are cow-derived. Talk to your doctor about your treatment.

What to do
  1. This is given in the hospital by the NICU team; there is nothing to manage at home.
  2. If the source matters to your family, tell the care team and ask them to note it.
  3. Bring this to a scholar you trust; the necessity here concerns a child's life.

This answered your Curosurf question. What about your other medications?

Curosurf is animal-derived in the medicine itself, so the answer is the same whoever makes it. Most medications are different: the animal ingredient is a hidden one, like the gelatin in a capsule or a coating, and its source changes depending on which manufacturer made your bottle. The label never says which.

A licensed pharmacist asks the manufacturer of your exact medication, in writing, and reports the stated source. Check one of your medications →
