Treatment of Sore Throat in Pregnant Women with Negative COVID-19, Strep A, and Influenza Tests
For a pregnant woman with sore throat and negative testing for COVID-19, strep A, and influenza, symptomatic treatment with acetaminophen is the safest first-line approach, as it is FDA-approved for use in pregnancy and has the most reassuring safety profile. 1
Recommended Treatment Approach
First-Line Symptomatic Management
Acetaminophen (paracetamol) is the preferred systemic analgesic for pregnant women with sore throat, as the FDA label specifically states it can be used in pregnancy after consulting a health professional 1
Avoid NSAIDs (ibuprofen, flurbiprofen) during pregnancy, particularly in the third trimester, despite their superior efficacy for sore throat in non-pregnant populations 2
Local anesthetics may be considered as adjunctive therapy if acetaminophen alone provides insufficient relief, though pregnancy-specific safety data are limited 2
Supportive Care Measures
Encourage adequate hydration and rest to support recovery from the presumed viral upper respiratory infection 3
Implement infection prevention measures including hand hygiene for at least 20 seconds with soap and water, avoiding sharing utensils or personal items, and cleaning frequently touched surfaces 4
Monitor for warning signs that would require escalation of care, including high fever, difficulty breathing, persistent symptoms beyond 7-10 days, or development of lower respiratory tract symptoms 3
Clinical Reasoning
Why Symptomatic Treatment Only
Most sore throats in this scenario are viral and self-limiting, given the negative testing for the most common bacterial (strep A) and serious viral (COVID-19, influenza) pathogens 3, 2
Antibiotics are not indicated without confirmed bacterial infection, as they lack efficacy for viral pharyngitis and carry unnecessary risks 2
Local antiseptics should not be recommended due to lack of efficiency data and primarily viral etiology 2
Pregnancy-Specific Considerations
Pregnancy physiology does not fundamentally alter the management of uncomplicated viral pharyngitis, though medication safety profiles must be carefully considered 3
The absence of pregnancy-specific data does not equal presence of harm, but caution dictates using medications with established safety profiles like acetaminophen 5
Mental health assessment should be conducted during any consultation with pregnant women, with appropriate referrals as needed 6
Red Flags Requiring Further Evaluation
Persistent high fever or signs of systemic illness may indicate a more serious infection requiring antibacterial therapy active against S. pneumoniae or H. influenzae 3
Development of respiratory distress, stridor, or barky cough could indicate laryngotracheitis, which may require corticosteroid therapy (prednisolone preferred in pregnancy) 7
Symptoms persisting beyond 7-10 days warrant re-evaluation for alternative diagnoses or bacterial superinfection 3
Common Pitfalls to Avoid
Do not prescribe local antibiotics or antiseptics for simple viral pharyngitis, as they lack proven efficacy and may cause unnecessary side effects 2
Do not withhold acetaminophen due to pregnancy - it has an acceptable safety profile when used appropriately 1
Do not assume all sore throats are benign - maintain vigilance for complications such as pneumonia, which can occur in pregnancy with similar frequency to non-pregnant patients but may have more serious consequences for both mother and fetus 3
