Leptospirosis treatment is a relatively complicated process comprising two main components - suppressing  the causative agent and  fighting possible complications. [[Aetiotropic]] drugs are [[antibiotics]], such as [[doxycycline]], [[penicillin]], [[ampicillin]], and [[amoxicillin]] (doxycycline can also be used as a [[prophylaxis]])There are no human [[vaccine]]s; animal vaccines are only for a few strains, and are only effective for a few months.  Human therapeutic dosage of drugs is as follows: doxycycline 100 mg orally every 12 hours for 1 week or penicillin 1-1.5 MU every 4 hours for 1 week.  Doxycycline 200-250 mg once a week is administered as a [[prophylaxis]].  In dogs, penicillin is most commonly used to end the leptospiremic phase (infection of the blood), and doxycycline is used to eliminate the [[asymptomatic carrier|carrier]] state.
Antimicrobial therapy is the mainstay of therapy for LeptospirosisLess severe cases can be treated with either [[Amoxicillin]], [[Ampicillin]], [[Doxycycline]], or [[Erythromycin]].   
 
Severe cases may be treated with high doses of intravenous [[Penicillin]].  Supportive therapy measures (esp. in severe cases) include [[detoxication]] and normalization of the [[Electrolyte#Physiological importance|hydro-electrolytic balance]].

Serum phosphorus levels may likewise increase to unacceptable levels due to renal failure. Treatment for hyperphosphatemia consists of treating the underlying disease, [[dialysis]] where appropriate, or oral administration of [[calcium carbonate]], but not without first checking the serum calcium levels (these two levels are related). [[Corticosteroid]]s administration in gradually reduced doses  (e.g., [[prednisolone]] starting from 30-60 mg) during 7-10 days is recommended by some specialists in cases of severe haemorrhagic effects.

Treatment

Antimicrobial therapy is the mainstay of therapy for Leptospirosis. Less severe cases can be treated with either Amoxicillin, Ampicillin, Doxycycline, or Erythromycin. Severe cases may be treated with high doses of intravenous Penicillin. Supportive therapy measures (esp. in severe cases) include detoxication and normalization of the hydro-electrolytic balance. Glucose and salt solution infusions may be administered; dialysis is used in serious cases.

Antimicrobial regimen

  • 2. Less severe
  • Preferred regimen: Amoxycillin OR Ampicillin OR Doxycycline OR Erythromycin
  • Alternative regimen: Ceftriaxone OR Cefotaxime OR Quinolone
  • Note (1): Treatment with effective antibiotics should be initiated as soon as the diagnosis of leptospirosis is suspected and preferably before the fifth day after the onset of illness
  • Note (2): Clinicians should never wait for the results of laboratory tests before starting treatment with antibiotics because serological tests do not become positive until about a week after the onset of illness, and cultures may not become positive for several weeks.
