The best and most simple online authoritative antibiotic guide in my opinion is

JHU ABX GUIDE

Most importantly it is regularly updated

It is freely available to all after you do a one time registration.

I find it very helpful in day to day practice when you want to clarify "doubts" on the drugs you use

Hope you will also find it useful

thank you JACK. it is useful.

Thanks a lot JACK for this online site. Really the best !!!!!!

thank you very much Jack...

But where is the neonatal dosage guidelines in JHU ABX GUIDE? Did I miss it?

Neofax is a very good source for Neonatal drug doses.
