Hello all! I am a new nursing student. Well, I actually just got accepted and I will begin in January. Anyway, the point of this post was to ask if there are any dangerous side effects of Lasix. I have an elderly friend... Read More

Does anyone know? I think lasix taking and not being f/u can drop the BP to a dangerously low level. Can another RN respond on this. thanks

I'm not sure if po lasix would have the same effect.If it's not too stupid of a question, how does Lasix cause ototoxicity? I'm familiar with its other side effects but I've never heard of this one before.
- 1Oct 20, '05 by AgnusIV lasix causes oto toxitiy. (usually temoprary) hearing loss if pushed too fast in an IV. Quite honestly it must be pushed very fast and is usually when a large amount is giving at high speed by IV.
If I give IV and it is a large quantiy I will often get a pump and put it on a pump. We often give very large amounts by IV push as much as 160 mg at a time. So I would be at the bedside a long time pushing that amount that is why I just put it on the pump. Time it to go 10mg a minute and can walk away. If I am very busy I will put smaller amounts on a pump especially if the patient already has one.
the danger does not exist with P. O. lasix.
As far as the question of potassium sparing diuretics. Lasix is more often that not the best diuretic. It is the one of choice for CHF. Potasium sparing diuretics works on a different part of the tubual and carries its own set of risks. Potassium must still be monitored because it spares all the potassium and you run the risk of potassium toxicity.
As far as your friend's reluctance to take potasium. Often the objection is the hunking size of the tablet.
Depending on the type she is receive sometimes (if scored) they can be broken. She should ask with her doctor and pharmasist for the smallest tablet available. Most people would rather take several small tablets than one humongious pill designed to choak an elephant. She can also ask the doctor or phamisist about breaking an unscored potassium tablet. There is also liquid potassium available.
Like what someone else also said take it with food as it does tend to upset stomachs.

I make it a practice to never give it fast push - always on a pump - and have a my kids on a monitor. Granted these kids are probably not the healthiest anyway, but I am shocked at the nurses on my floor that have also witnessed this same thing happen and continue to 1) push the lasix 2) kids not on monitors.
- 1Mar 17, '09 by NotReady4PrimeTime Senior ModeratorThe cause of loop diuretic-associated hearing loss is thought to be a marked reduction in endocochlear action potentials through the inhibition of sodium-potassium activated ATPase in the stria vascularis. There are also dramatic changes in the electrolyte composition of endo- and perilymph (<K and >Na) within the semicircular canals that may affect hearing acuity as well. Physical changes in the hair cells and the stria vascularis are also thought to be implicated. There's a very complex explanation at this link; http://books.google.ca/books?id=T5AN...esult#PPA43,M1

Ototoxicity refers to the fact that if lasix is pushed too fast, it can cause tinnitus.
We don't have syringe pumps at the hospital where I work, so when the order comes down for 80-160 mg Lasix Iv push, it can be kind of a bugger.
We're working on getting syringe pumps for just this sort of occasion.
