Haemophilus Influenzae: Drug Therapy

Therapeutic targets

  • Elimination of the pathogens
  • Avoidance of complications

Therapy recommendations

  • Antibiosis (antibiotic therapy):
    • Cephalosporins are used for life-threatening infections
    • If there is no danger to life, the active ingredient ampicillin is the drug of choice.
  • Symptomatic therapy (if necessary antipyretics / drugs that reduce fever).
  • See also under “Further therapy”
  • Post-exposure prophylaxis (PEP) [see below].
  • See also under “Further therapy“.

Postexposure prophylaxis (PEP)

Post-exposure prophylaxis is the provision of medication to prevent disease in individuals who are not protected against a particular disease by vaccination but have been exposed to it.

Indications (areas of application)

  • Persons with close (“face to face”) contact with a diseased person, ie:
    • All household members from the age of 1 month, provided that there is an unvaccinated or inadequately vaccinated child up to the age of 4 years, or else a person with relevant immunodeficiency or suppression (immunodeficiency).
    • Unvaccinated children up to 4 years in community settings.

Implementation

  • Persons with close (“face to face”) contact with a sick person:
    • Chemoprophylaxis – rifampicin (antibiotic).
      • From 1 month: 20 mg/kg/day (maximum 600 mg) in 1 ED for 4 days.
      • Adults: 600 mg p.o. in 1 ED for 4 days.
      • In pregnant women, the administration of rifampicin is contraindicated (prohibited)! Here, instead of rifampicin ceftriaxone, also an antibiotic, is prescribed.

Prophylaxis (prevention) should be given at the earliest possible time, no later than 7 days after the onset of the index case (first documented case of disease).
