Treatment of Bacterial Tonsillitis in Pregnancy

First-line Treatment

• Penicillin G or Ampicillin are preferred due to their narrow spectrum of activity and established safety profile, as recommended by the Centers for Disease Control and Prevention (CDC) 1
• For non-anaphylactic penicillin allergy, first-generation cephalosporins (e.g., cefazolin) are recommended by the CDC 1

Alternative Treatments

• Clindamycin can be used if the bacterial isolate is susceptible, as recommended by the CDC 1
• Erythromycin is an alternative if the isolate is susceptible, according to the CDC 1
• Vancomycin may be used when susceptibility testing is not available or isolates are resistant to clindamycin and erythromycin, as recommended by the CDC 1

Medications to Avoid

• Oral decongestants should not be used, especially during the first trimester, due to potential association with congenital malformations, as reported by the American Academy of Allergy, Asthma, and Immunology 2

Special Considerations

• Intranasal corticosteroids, such as budesonide, fluticasone, and mometasone, may be safely used for associated nasal symptoms during pregnancy, according to the European Rhinologic Society 3
• The first trimester carries the highest risk for medication-induced teratogenicity, so non-urgent treatments should be carefully evaluated during this period, as recommended by the European Rhinologic Society 3

Treatment of Tonsillitis in Pregnant Women

Antibiotic Selection

• Penicillin antibiotics are the first-line treatment for tonsillitis in pregnant women, with cephalosporins as an appropriate alternative for those with penicillin allergy 4, 5
• Avoid tetracyclines, aminoglycosides, trimethoprim-sulfamethoxazole, and fluoroquinolones during pregnancy due to potential fetal risks 4

Treatment Approach

For Bacterial Tonsillitis:

• For penicillin-allergic patients, first-generation cephalosporins are recommended if the allergy is not anaphylactic 5

For Symptomatic Relief:

• Saline gargles are safe and may provide symptomatic relief 5
• Acetaminophen (paracetamol) can be used for pain and fever control 5
• Avoid oral decongestants as they may increase risks during pregnancy 6, 7

Special Considerations in Pregnancy

• Consider consultation with an obstetrician for pregnant women with severe infections or complications 8
