From the Guidelines
The recommended dose of ceftriaxone for gonorrhea treatment is 250 mg as a single intramuscular injection, accompanied by azithromycin 1 g orally as a single dose. This recommendation is based on the most recent evidence from the Centers for Disease Control and Prevention (CDC) 1, which suggests that ceftriaxone 250 mg intramuscularly, in combination with azithromycin 1 g orally, is the most reliably effective treatment for uncomplicated gonorrhea. The use of ceftriaxone is effective because it inhibits bacterial cell wall synthesis and maintains high concentrations in blood and tissues.
Some key points to consider when treating gonorrhea include:
- The importance of testing for co-infection with chlamydia and treating accordingly
- The need for patients to abstain from sexual activity for 7 days after treatment completion and until all partners have been treated to prevent reinfection
- The potential for gonorrhea to develop resistance to multiple antibiotics, which is why combination therapy with ceftriaxone and azithromycin is recommended
- The importance of follow-up testing to ensure cure if symptoms persist
It's worth noting that the CDC no longer recommends cefixime as a first-line treatment for gonorrhea due to concerns about emerging resistance 1. Additionally, fluoroquinolones are not recommended for treatment of gonorrhea in many areas due to the spread of quinolone-resistant N. gonorrhoeae 1.
Overall, the recommended treatment regimen of ceftriaxone 250 mg intramuscularly and azithromycin 1 g orally as a single dose is the most effective and reliable option for treating uncomplicated gonorrhea, based on the latest evidence from the CDC 1.
From the FDA Drug Label
For the treatment of uncomplicated gonococcal infections, a single intramuscular dose of 250 mg is recommended. The recommended dose of ceftriaxone for uncomplicated gonococcal infections is a single intramuscular dose of 250 mg 2.
- This dose is recommended for adults.
- It is essential to note that if Chlamydia trachomatis is a suspected pathogen, appropriate antichlamydial coverage should be added, as ceftriaxone has no activity against this organism.
From the Research
Ceftriaxone Dose for Gonorrhea
- The recommended dose of ceftriaxone for the treatment of gonorrhea has evolved over time, with various studies suggesting different dosages.
- A study from 1991 3 compared the efficacy of single-dose cefixime with ceftriaxone for the treatment of uncomplicated gonorrhea, with a dose of 250 mg of ceftriaxone administered intramuscularly.
- However, more recent guidelines from 2020 4 recommend a single 500 mg IM dose of ceftriaxone for the treatment of uncomplicated urogenital, anorectal, and pharyngeal gonorrhea.
- Another study from 2022 5 compared the efficacy of high-dose intravenous ceftriaxone and oral cefixime combined with doxycycline for the treatment of Chlamydia trachomatis and Neisseria gonorrhoeae co-infection, with a dose of 1 g intravenous ceftriaxone.
- A pharmacodynamic evaluation from 2024 6 suggested that a ceftriaxone 1 g single-dose intramuscularly may cure most anogenital and oropharyngeal gonorrhoea cases caused by currently internationally spreading ceftriaxone-resistant gonococcal strains.
- Additionally, a review from 2022 7 recommends a single 500-mg dose of intramuscular ceftriaxone for the treatment of uncomplicated gonococcal infection in people weighing less than 331 lb (150 kg).
Dosage Considerations
- The dosage of ceftriaxone may vary depending on the specific circumstances of the infection, such as the presence of co-infection with Chlamydia trachomatis.
- It is essential to follow current guidelines and consult with a healthcare professional to determine the most effective treatment regimen for gonorrhea.
- The use of ceftriaxone in combination with other antibiotics, such as doxycycline, may be recommended in certain cases 4, 5, 7.
