This information and facts should be contained inside the “Precautions” portion on the labeling of all LVIs Utilized in TPN therapy. If the most quantity of aluminum in SVIs and PBPs is 25 µg for more info each L or fewer, as opposed to stating the exact amount of aluminum that every might have, as in paragraph (d), the fast container label for SVIs and PBPs Employed in the preparing or during the administration of TPN injections (with exceptions as pointed out down below) and injectable emulsions may well condition: “Has not more than 25 µg/L of aluminum”. In case the SVI or PBP is often a lyophilized powder, the speedy container label may perhaps point out the next; In case the SVI or PBP can be a lyophilized powder used in the preparation of TPN injections and injectable emulsions, the speedy container label will have to condition the next: “When reconstituted in accordance Together with the bundle insert Directions, the focus of aluminum are going to be no more than twenty five µg/L”.
