As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.

Other General Ceftriaxone Dosage Information

Here are some other important points about taking ceftriaxone:
 
  • For both adults and children, ceftriaxone is given either as a shot or through an intravenous line (IV).
     
  • Ceftriaxone should be administered at the same time each day to maintain an even level of ceftriaxone in your system.
     
  • For ceftriaxone to work properly, it must be administered as prescribed.
     
  • Make sure that you complete your entire course of ceftriaxone, even if you start feeling better. This will ensure that the infection is completely treated.
     
  • Never receive outdated ceftriaxone. Taking any outdated medication may cause serious problems because the intended effects often change after the medicine expires.
     
  • If you are unsure about anything related to ceftriaxone or your ceftriaxone dosage, please talk to your doctor, nurse, or pharmacist. Do not stop receiving ceftriaxone without first discussing it with your healthcare provider.
