Phenergan is the brand name of promethazine.
Promethazine has been widely documentated in research to cause tissue necrosis (AKA gangrene) when extravasation occurs. This supposedly has been known since the 1960s.
What is extravasation? That's when the drug goes through the blood vessel into the surrounding tissue. What type of drug administering mostly causes extravasation? IV. Why? Because frequently the needle insertion often allows some of the drug to enter the surrounding tissue.
Promethazine is also listed as a vesicant. A vesicant is a substance that causes either irritation or damage upon contact with skin and muscle tissue.
Because of this, the drug manufacturer should have declared that using Phenergan (promethazine) via IV injection would cause tissue necrosis (gangrene) if not done properly.
When the plantiff was administered this drug via IV injection, no such warning label was present. A lesser one was there instead. Since this incident, the label has been changed accordingly.
I also found a discussion about this case and the drug in question among various nurses:

We had our own problem here at U of L not to long ago. A patient in the ER had an IV site in the right brachial vein in the bend of the arm (ER's favorite place to put um) that extravasated after a push of phenergan (diluted like it should be, not that it actually helps) and ate through the brachial artery at the same time. We tried to save the arm, but she ended up losing it anyway. The hospital is fianally listening to us, but that is what it took to make them listen. The patient has become a great advocate for others.
We also just got rid of Dilantin. It only took us 3 years and multiple law suites
. The patients want the phenergan, the doc's say it works so well, and it is cheap. It's been a long battle, but I think it is FINALLY coming to an end. Thank God!

One of our IV RNs testified as an expert for this case. I am familiar with Diana - through a close friend, and I sang in an a capella group with her sister. It's had a big impact in our small Vermont communities.
I'm grateful not for her tragedy, but am grateful that it has gained national attention. Because of it, it seems that all of the ISMP alerts about phenergan that I hand out to MDs and RNs are having more of an impact. We may be able to remove the IV route from formulary.
I pray the Supreme Court does the right thing, and that the precedent that will be set by this decision will be on the side of the consumer - not the drug manufacturer. Perhaps the labeling issues r/t heparin this year will help decide this case.

The IV injection of promethazine has had reported risk documented as far back as the 1960's when accidental arterial injection was reported. My first case involving promethazine extravasation was in 1996 and I found this statement in the book Intravenous Medications, published annually be Mosby even back then - "Determine absolute patency of the vein. Extravasation will cause tissue necrosis." I also published articles in Nursing99 and Nursing2002 listing promethazine as a vesicant.
In August of 2006, ISMP published their warning about this drug which was based on numerous lawsuits that had been published in regular newspapers. This was truly not the beginning of the problem. It was the first time that a nationally recognized organization published anything calling attention to this problem.
It is my firm belief that each facility must take a hard look at all of their anti-emetic practices with a strong policy created. Promethazine IV must be treated with the same high level of respect that all other antineoplastic agents receive. A literature search will produce numerous articles about the benefits of promethazine as an antiemetic, however there is almost nothing in the professional literature about the horrible outcomes with this drug when the correct nursing actions are not taken.
When I look at a case, I consider what the nurses did to prevent the problem as outlined in the INS standards of practice, how quickly did they recognize that an infiltration/extravasation was happening, and what interventions did they use to mitigate the problem.
The national standard has always been that the nurse must know the drugs they are giving and the possible problems and how to administer them safely. This is not anything new.
