Anaplasmosis Treatment with Life-Threatening Doxycycline Allergy, Severe Intolerance, or in Pregnancy
When the standard antibiotic for anaplasmosis is contraindicated, a specific protocol guides selection of an alternative approach. This page addresses three situations: life-threatening allergy to doxycycline, severe doxycycline intolerance, and pregnancy where the clinical course of anaplasmosis is mild.
Physicians should consider alternate antibiotics in cases of life-threatening allergy to doxycycline or severe doxycycline intolerance. Alternative antibiotics are also appropriate for pregnant patients whose clinical course of anaplasmosis appears mild.
Rifampin is the alternative antibiotic considered in this setting, used in consultation with an expert in infectious diseases. The full protocol — including patient selection, management guidance, and the complete evidence-based regimen — is available below.

In cases of life-threatening allergies to doxycycline or severe doxycycline intolerance, physicians should consider alternate antibiotics.
Alternative antibiotics should also be considered for pregnant patients for whom the clinical course of anaplasmosis appears mild.
Rifampin has been used successfully in several pregnant women with anaplasmosis.
Small numbers of children under 8 years of age have also been treated successfully for anaplasmosis with rifampin using a 7–10 day treatment course.
The use of antibiotics other than doxycycline should be made in consultation with a specialist in infectious disease.
