Overview

The mainstay of therapy for Lyme disease is antimicrobial therapy. Antimicrobial therapy may include doxycycline, amoxicillin, cephalosporins, or macrolides. The choice of antimicrobial therapy depends on the stage of Lyme disease. Individuals who remove attached ticks should be monitored closely for signs and symptoms of tick-borne diseases for up to 30 days.

Follow-up

Approximately 10 to 20% of patients treated for Lyme disease with a recommended 2-4 week course of antibiotics will develop post-treatment Lyme disease syndrome (PTLDS). Patients report lingering symptoms of fatigue, pain, or joint and muscle aches. In some cases, these can last for more than 6 months.
The majority of patients with post-treatment Lyme disease syndrome gradually improve over months/years of the primary infection.

-A controversial new guideline developed by the American Academy of Neurology, finds conventionally recommended courses of antibiotics are highly effective for treating nervous system Lyme disease. They find no compelling evidence that prolonged treatment with antibiotics has any benefit in treating symptoms that persist following standard therapy. The guideline is endorsed by the Infectious Diseases Society of America (IDSA). However, these guidelines refer mostly to early acute lyme neuroborreliosis, as there is a paucity of studies on late lyme encephalopathy and parenchymal CNS disease. The guideline leader was John J. Halperin and was co-written by Gary Worsmer and Eugene Shapiro, neither of whom are neurologists. Halperin, Worsmer and Shapiro were all co-authors of the IDSA Lyme guidelines released in 2006 by the Journal of Clinical Infectious Diseases. There is significant disagreement with this guideline (www.ilads.org).

-Approximately 10 to 20% of patients treated for Lyme disease with a recommended 2-4 week course of antibiotics will have lingering symptoms of fatigue, pain, or joint and muscle aches. In some cases, these can last for more than 6 months. Although often called “chronic Lyme disease,” this condition is properly known as “Post-treatment Lyme disease Syndrome” (PTLDS).
+**** Alternative regimen (1): [[Doxycycline]] 100–200 mg q12h for 14 days '''(avoid in [[pregnancy]])'''
+*** 2.1.2 '''Pediatric'''
-The exact cause of PTLDS is not yet known. Most medical experts believe that lingering symptoms are due to residual damage to the tissues and the immune system that occurred during the infection. Similar complications and auto-immune responses are known to occur following other infectious diseases.
+**** Preferred regimen (1): [[Ceftriaxone]] 50–75 mg/kg/day IV q24h (maximum, 2 g/day)
+**** Preferred regimen (2): [[Cefotaxime]] 150–200 mg/kg/day IV q6–8h (maximum, 6 g/day)
-In contrast, a few health care providers tell patients that these symptoms reflect persistent infection with Borrelia burgdorferi. However, there is no credible scientific evidence that PTLDS is caused by persistent infection. More importantly, studies have shown that patients treated with prolonged courses of antibiotics do not do better than patients treated with placebo.

+**** Alternative regimen (1): [[Doxycycline]] '''(for children aged ≥ 8 years)''' 4–8 mg/kg/day q12h (maximum 200 mg/day)
-The good news is that patients with PTLDS almost always get better with time; the bad news is that it can take months or even years to feel completely well. If you have been treated for Lyme disease and still feel unwell, see your doctor to discuss how to relieve your suffering. Doctors may want to treat you in ways similar to patients who have [[fibromyalgia]] or [[chronic fatigue syndrome]]. This does not mean that your doctor is dismissing your pain or saying that you have these conditions instead. It simply means that the doctor is trying to help you cope with your symptoms using the tools available.

+===Follow-up===
-::* Parenteral regimen
+*Approximately 10 to 20% of patients treated for [[Lyme disease]] with a recommended 2-4 week course of [[Antibiotic|antibiotics]] will develop [[Lyme disease natural history, complications and prognosis|post-treatment Lyme disease syndrome (PTLDS)]]. Patients report lingering symptoms of [[fatigue]], [[pain]], or [[Joint aches|joint]] and [[muscle aches]]. In some cases, these can last for more than 6 months.
-:::* Preferred regimen: [[Ceftriaxone]] 2 g IV q24h for 14 (14–21) days
+*The majority of patients with [[Lyme disease natural history, complications and prognosis|post-treatment Lyme disease syndrome]] gradually improve over months/years of the primary [[infection]].
-:::* Alternative regimen: [[Cefotaxime]] 2 g IV q8h for 14 (14–21) days {{or}} [[Penicillin G]] 18–24 million U/day IV q4h for 14 (14–21) days
-::* Oral regimen

-:::: Note (1): Parenteral regimen is recommended at the start of therapy for patients who have been hospitalized for cardiac monitoring; oral regimen may be substituted to complete a course of therapy or to treat ambulatory patients.
-:::: Note (2): A temporary pacemaker may be required for patients with advanced heart block.
-:::: Note (3): Patients treated with macrolides should be closely observed to ensure resolution of the clinical manifestations.
