anyone use lovenox in odd doses? i.e. 76mg?

Hi everyone,

this is a question for those who work often with Lovenox. I know it is available in 30 and 40mg syringes that are not to be messed with or the air bubble expelled due to possible loss of drug. However, I was under the assumption that the higher dose syringes, i.e. 60mg, 80mg and 100mg are all able to be calibrated to the ordered dose. those syringes are calibrated on the side like a regular syringe. i am asking because we have an issue at our work and the nurses are fighting about whether other places use unusual doses of the med, such as 54 mg for example. i saw on the website that lovenox is also available in multidose vials. several of our pts have come with unusual dose orders from the hospital, and i know the docs usually dose it based on weight in kilogram, usually 1mg per kg. so if someone weighs 76 kg, usually the dose will be written for 76mg of lovenox, which would mean expelling just a small amount out of a 80mg syringe.

does anyone else out there have experience with unusual doses of lovenox? if so, i would love to know that other people have done the same as our place. i am tired of people writting "error reports" out on something that is not an error. it says in the drug guide, and per pharmacy that the higher dose prefilled syringes are able to be adjusted, so i don't know why this has caused such a problem.

thank you for your input and answers!

100 cc syringe????

Oh, you know what I mean! 100mg prefilled syringes of Lovenox! 100 cc would be an awful big syringe, esp to fill with Lovenox :)

i can't wait to get out of this stressful, hostile work environment. thanks again for everyone's help and for telling me how you have done things on your units. i really appreciate everyone's replies!

Definitely time for you to take a "vacation" and find employment elsewhere.

With regard to specific dosing, yes, we also give specific amounts of lovenox --i.e. 82mg.

All right I am a bit slow on the uptake this morning. Three pages on this thread and I still don't understand the original poster's infraction.... At least not beyond the facility's/physician's expectation that the lovenox be given in precise (as ordered/weight based) doses.

1) Is the facility saying that it is not possible to give precise dosing by wasting a portion of a premixed syringe ?

2) If so, are multiple dose vials available with the expectation that they be used?

3) Is someone witnessing your waste and arguing that you are doing so incorrectly?

4) How are others administering Lovenox on your unit such that they are avoiding write-ups?

We do the wight based Lovenox as well 1mg/kg-we have to waste from whatever appropriate syringe to get the correct dose.

sorry, i didn't see glasgow3's question about my situation.

the issue is this. an admit came in, day shift had gotten the admit at noon, but didn't write out the MAR or fax anything to the pharmacy. the original order was for 55mg.

that night, the dose was given at 55mg as ordered. the next day, day shift nurse (same one from day before) said you can waste out of the syringe. i tried to tell her, that yes, you CAN infact waste out of the larger syringes, but not the 30mg or 40mg syringe, as it's not calibrated. thie 55mg was taken from the 60mg syringe, which is calibrated on the side.

nevertheless, it was still written up as a med error. why? because the nurses there have no clue why lovenox is given as a weight based med sometimes. i can't help that. but managment thinks the exact same way. this information is everywhere: on the manufacturer instructions, in the PDR, nurses drug book, etc. this is a LTC. they are in the dark ages.

that's why i came here to see what other nurses do. i know i'm right. i just wanted some more people to tell me they do the same thing.

hope that clears things up a bit.
