Good day everyone, girls ? The baby's bilirubin is 152, they took a phototherapy lamp. The baby is one month and a week old. The doctor only prescribed ursodeoxycholic acid, we decided to take a phototherapy lamp ourselves. I wanted to ask if it's necessary and possible to take ursodeoxycholic acid and put the baby under the lamp? Or can we just use the lamp? And please tell me what's more effective: the lamp or medication?
