From the FDA Drug Label

Acute epididymo-orchitis caused by N. gonorrhoeae: 100 mg, by mouth, twice a day for at least 10 days. Acute epididymo-orchitis caused by C. trachomatis: 100 mg, by mouth, twice a day for at least 10 days The antibiotics used to treat epididymo-orchitis are:

  • Doxycycline for cases caused by C. trachomatis or N. gonorrhoeae 1

From the Research

Introduction to Epididymo-Orchitis

Epididymo-orchitis is a common urological condition characterized by the inflammation of the epididymis and/or testis, often caused by sexually transmitted infections or enteric organisms. The treatment of epididymo-orchitis typically involves the use of antibiotics.

Antibiotics Used in Treatment

The choice of antibiotic depends on the suspected causative organism and the patient's age. For sexually acquired epididymo-orchitis, the first-line empirical treatment is:

  • Ceftriaxone 1g intramuscularly, as recommended by the British Association for Sexual Health and HIV 2
  • Doxycycline, which is often used in combination with ceftriaxone for the treatment of gonococcal and chlamydial infections 2, 3

Treatment of Non-Gonococcal Epididymo-Orchitis

For patients with epididymo-orchitis probably due to non-gonococcal organisms, the recommended treatment is:

  • Ofloxacin or doxycycline, which are effective against common enteric organisms and Chlamydia trachomatis 2, 4
  • Moxifloxacin, which may be used if Mycoplasma genitalium is identified as the causative organism 2

Treatment of Enteric Pathogen-Related Epididymo-Orchitis

In cases where enteric pathogens are suspected, such as in older patients or those with urinary tract abnormalities, the recommended treatment is:

  • Ofloxacin or levofloxacin, which have adequate penetration into genital tissues and are effective against enteric organisms 2, 4

Important Considerations

It is essential to note that the treatment of epididymo-orchitis should be guided by the patient's clinical presentation, age, and suspected causative organism. The use of antibiotics should be tailored to the specific needs of each patient, and treatment should be started empirically in patients with objective swelling and tenderness on testicular examination 2. Additionally, the rising resistance to fluoroquinolones, such as ciprofloxacin, highlights the need for alternative antimicrobials with adequate penetration into genital tissues 5.

Dosing and Duration

The dosing and duration of antibiotic treatment for epididymo-orchitis vary depending on the specific antibiotic and the patient's condition. For example, ceftriaxone is typically administered as a single 1g intramuscular dose, while doxycycline is often given orally for 10 days 2, 4. It is crucial to follow the recommended treatment guidelines and to complete the full course of antibiotic therapy to ensure effective treatment and prevent complications.

Conclusion

In conclusion, the treatment of epididymo-orchitis involves the use of antibiotics, with the choice of antibiotic depending on the suspected causative organism and the patient's age. It is essential to follow the recommended treatment guidelines and to complete the full course of antibiotic therapy to ensure effective treatment and prevent complications.
