Typical dosage for Ceftriaxone

Ceftriaxone is given as an injection into the veins or into the muscle, usually by a provider in a healthcare setting (e.g., hospital, office, nursing home).

The dose and length of treatment depends on what type of infection you have and how serious it is. Your provider will determine the right dose and length of treatment for you. For most infections, the general dosage is as follows:

Adults

  • Most infections: The typical dose is 1 to 2 grams per day for 4 to 14 days.
  • Gonorrhea: The recommended dose is 250 mg injected into the muscle for one time.
  • Preventing infections before surgery: The typical dose is 1 gram injected into the vein once, 30 minutes to 2 hours before surgery.
  • The maximum dose is 2 or 4 grams per day, depending on your age and liver and kidney function.

Children

  • Most infections: The dose depends on your child's weight. The typical dose is 50 mg/kg to 75 mg/kg of body weight per day for 7 to 14 days. This dose is given once per day or split into two equal doses in the day. The maximum dose is 100 mg/kg (up to 4 grams) per day.
