thank god i do nocturnal in unit and i get Benadryl shots anytime I wake up. I average about 4 per 8 hour treatment. Its the only thing that gets me through treatments it puts me to sleep and totally relaxes me its AMAZING..lol Do any of you get I.V Benadryl while dialysing? Oh and i know i told you earlier i get 4 benadryl injections throughout my treatment. my Doc says its harmless thats why he lets me get so many because the machine filters it quite quickly after its injected. Is he right? Is there any harm in taking so much during my treatments?
I will try to explain what I think is happening to your Benadryl. The tubing we use at dialysis (and everyone should be using something similar) have small ports, one on the arterial side and one on the venous side. The port on the arterial side is red and the one on the venous side is blue. There is also a place on the machine for the nurses to give you any IV meds you may need during treatment (epo, heparin, etc). I take an IV medication for nausea each treatment. I was taught to put it in the blue port and here is the reason why: any medication put into the arterial side would be quickly filtered out as it travels into the machine with the blood from your artery and thru the filters (just as your doctor said). If you put the medicine into the blue port, it is injected into blood which has already gone thru the machine and been filtered. This blood is now returning to your body and so the medicine will not be filtered out before it is absorbed by the body. I also realize that your blood does not just go thru the machine one time, but it truly makes a difference.
You may still require more Benadryl than you would take by mouth, but not nearly the amount you seem to need now. 4 injections for one treatment sounds like an awful lot of Benadryl, but it depends on how much they are actually giving you each injection. One last comment
- your dr. may say it is harmless, but if you require the medicine to put you to sleep or at least relax you enough to fall asleep (and help you to go back to sleep), then your body becomes dependent on this medicine. I am not saying that occasional use would be harmful, but repetitive use
can be. Many people who work the night shift take Benadryl to sleep during the day. When these people switched to a different shift, 75% of them still required the Benadryl to go to sleep. Just be aware of what you are taking and how it affects your body. Anything taken in a large enough dose can be detrimental, even water. Our bodies are up to 75% water, but too much IV saline or drinking too much water can cause serious side effects, even for people who
don't have kidney problems. I hope this helps answer your question.
