What is the maximum number of intravenous ceftriaxone courses recommended in Lyme disease?

Explanation:
Lyme disease treated with intravenous ceftriaxone is given for a finite course to balance effectiveness with the risks of IV antibiotics. A single IV course is the standard approach, with duration often in the 14–28 day range depending on the manifestations. If symptoms persist or a relapse occurs after the first course, a second IV course may be considered, but there is little evidence that a third or subsequent course provides additional benefit and the risks rise with more exposure. Therefore, the maximum number of intravenous ceftriaxone courses recommended is two.
