Brief Answer:
what the CDC recommends
Detailed Answer:
Hello,
The Center for Disease Control recommends a single dose of Ceftriaxone (an injection) plus levofloxacin or ofloxacin for 10 days for treatment of epididymitis.
If he did not get the injection, this could be part of the problem. He may need to get the injection and then a course of the antibiotic doxycycline (which should be cheaper than the ofloxacin.
I hope he is better soon,
