Question: (1) If a patient has suspected sepsis and is administered ceftriaxone 1g then does it make any difference with regard to efficaciousness if the antibiotic is administered rapidly into a canulla, administered by slow drip or administered intra muscularly? (2) Typically, how long does it take to administer IV ceftriaxone 1g by slow drip (rougly how many minutes)? (3) If a patient needs to be on a saline solution for sepsis to avoid dehydration then are there any potential problems in adding the ceftriaxone to the saline solution at the same time?

Brief Answer:
short IV push is preferred

Detailed Answer:
Thanks for your query.

Ceftriaxone is recommended to be administered as short IV push injection or intramuscular. There is not much difference in efficacy but higher doses are usually given IV as intramuscular would require too many pricks. It is not required to give ceftriaxone in a slow drip in 50-100 ml saline over 1/2 to 1 hr but it can surely be given like that. No difference in efficacy is expected.

In IV push it has to be given over 2-5 min.

Giving ceftriaxone in IV fluids over 4-6 hr has not been studied and hence not recommended.

Hope this helps.

Thank you kindly Dr. XXXXXXX for your very clear and informative answers. May I ask one more related question? If it is not recommended to add ceftriaxone to a saline solution then could an IV administration of ceftriaxone and IV fluids be administered SEPARATELY at the same time? Or would it be unusual or ridiculous to use two different canulla at the same time?

Brief Answer:
yes it would be unnecessary

Detailed Answer:
The usual practice is to continue the IV fluids as required and at the time of ceftriaxone administration to stop it, give the injection as short IV push and then restart the IV fluids.

This can be done by a three way connector so that no tubing has to be removed.

I have an indentation in my lower leg near my shin bone that just showed up from the way i was sitting. It s going away slowy, seems like it would be from edema (pitting) maybe? As far as i know i m healthy but did have gastric bypass surgery almost a year ago and have lost more than 90 lbs. I weigh 129 right now at 5 3 . Could this indention be caused by dehydration?

Is it possible that taking Claritin contributed to the weakening of the walls of the disks in my spinal column? I have a herniated disk and wondered if taking Claritin for a year( with the dehydration that comes with the medication) could have caused the herniation.

My son aged 15 was I believe misdiagnosed with ulceraive colitis in February. His dioreahha episode began after sitting in a unventilated room for long hours next to a window with black mould and putting on the airconditioning.The reason i disagree with this diagnosis is that after a while in hospital recieving blood transplant and medication he did not recover and had another episode in July when again he used airconditioning to cool down, He then went to a specialist in Ankara Turkey where they discovered his medication was causing problems with his pancreas and kidneys and immediatly stopped it. there he did not adhere to any kind of diet he just began to eat and walk as much as his strength would allow. After 10 days hte diarehha disappeared and the doctor gave him Iron supplements to help his anemia . A few weeks ago the weather turned cold. Again he used the airconditioning. Again he began to get dioreahha began geting slight pains in his stomach and going to the lavatory about once every hour and was running a slight temperature . He became afraid to eat has got a few red patched on his legs maybe due to dehydration and malnutrition . He is currently in hospital where a specialist who helped a friend in a similar condition has given him antibiotics along with vitamins for a stomach infection. So could my son be a victim of black mould? it looks that way to me
