Keflex How Much To Give for 12lb 3oz baby ?

Answer 1

The usual recommended daily dosage of Keflex for pediatric patients is 25 to
50 mg/kg in divided doses.

Your baby's weight is about 5.5 kg so to calculate the dosage, it will come up as 137.5 - 275 mg in divided doses is required daily.

If your supply is Keflex Suspension 125 mg per 5 mL (1 teaspoon), you need to give
5.5 - 11 ml daily. It would then be good to give 1 tsp every 12 hours.

If your supply is Keflex Suspension 250 mg per 5 mL (1 teaspoon), you need to give
2.75 - 5.5 ml daily. It would then be good to give half tsp every 12 hours.

Answer 2

You probably have the 125mg per 5 cc (one teaspoon) liquid.
If this were my baby, I would use 125 mg or one teaspoon every 8 hours. This is a generous amount - - half of this may be plenty - - but I'd rather be a bit high than too low IF the baby has a bacterial infection for which Keflex is indicated such as a bacterial middle ear infection or bacterial respiratory tract infection. There should be directions in the package insert or prescribed on the bottle by the physician who wrote for this antibiotic. It is always best to check with your primary physician. You must also be sure the baby has no history of allergy to this medication. In general, there isn't a great concern about too much dosage for this antibiotic.

Added note considering answers below - - As I said, half a teaspoon would probably be plenty. I realize Keflex is not the first choice for respiratory infections. My assumption is that Keflex is what you have. I prefer every 8 hours to every 12 hours since Keflex does not stay in the system very long.
If you don't have the perfect antibiotic, you use what you have. Not everyone has easy and affordable access to a good primary care physician. I assume you have a sick baby at home and no easy way to get specialty help. I doubt you would ask this question if you had a doctor you could contact.

I am a retired MD with experience as an ER physician, internal medicine, hematology, and oncology. I realize that affordable, accessible medical care is not always perfectly provided for everyone here in the USA.

Keflex Dosage

Answer 5

I'm going to be very honest with you. I'm a pharmacist, and I can tell you doses depending on what your child has. But, I really don't know what does the baby has, how old is he (or she). The weight by itself is not good enough to give you a dose. And sometimes, people end up giving antibiotics when the patient does not need them. I know this is not an answer to your question, but as a professional, my recommendation is that if your child is sick, go to the doctor. If this is for some kind of homework, you don't have enough info to solve the problem. But if this is for real, take the baby to the doctor. It may take a little more time, but surely it will be more effective to give the baby what he or she needs instead of giving only what you have. Take care.

Answer 6

The dose is dependent on the diagnosis and is based on mg/kg of body wt in divided doses. Contrary to the first responders answer, Keflex is not generally acceptable for respiratory infections, as it lacks the coverage for many infectious organisms.

The first responder also recommended a dose of 375 mg per day which is higher than the general dose for an infant of this weight.

Please see your family practice or pediatric physician or nurse practitioner for recommendations on use of antibiotics in any infant.

Answer 7

The doc usually makes it clear how much to give, I hope you are not just doing this on your own. A 12pound baby is very fragile. Do be careful......Thanks You can call the office of the prescriber for clarification.
