The unavailability of pharmaceuticals for NICUs

We have come across that medicinal products have become unavailable. Our three latest examples are

• dextrose gel used for hypoglycemia management (I think this is a food supplement, but still)
• iron drops for supplementation preterm infants (so, used a lot!)
• multivitamin drops for preterm infants (finally back on the shelf...)

@Bernhard Csillag also posted about phenobarb (see link below)

Do you share this experience in your various contexts?

I understand that newborns and especially preterm infants are small patient groups for companies to "build business around", and that we have less "power" than say cardiologists working with much larger numbers of patients.

However, if this is a trend, that availability of products we need is challenged, that would be very worrying
