From the Guidelines
For a cough during the first trimester caused by a URI, conservative non-medication approaches are generally recommended first, prioritizing hydration, rest, and the use of a humidifier to moisten the air, as these methods are safe and effective in managing symptoms without posing risks to the fetus 1.
Key Recommendations
- Start with adequate hydration to help thin out mucus and soothe the throat.
- Rest is crucial to help the body fight off the infection.
- Using a humidifier can add moisture to the air, which helps relieve cough and congestion.
- Honey (1-2 teaspoons as needed) can effectively soothe the throat and suppress cough in adults, though it should be avoided in infants under 12 months.
- Saline nasal sprays can help with congestion by moisturizing the nasal passages.
Medication Use
If medication is necessary, acetaminophen (Tylenol) is considered safe for fever and discomfort at regular doses (650mg every 6 hours, not exceeding 3000mg daily) 1. Most cough suppressants and decongestants should be avoided in the first trimester due to limited safety data. Specifically, pseudoephedrine, phenylephrine, and combination cold medicines should be avoided. Dextromethorphan may be used sparingly if the cough is severe and affecting sleep, but only after consulting with a healthcare provider.
Rationale
This cautious approach is recommended because the first trimester is a critical period for fetal organ development, and unnecessary medication exposure should be minimized. Most URIs are viral and will resolve within 7-10 days with supportive care alone. The management of cough in pregnancy, especially during the first trimester, requires careful consideration of the potential effects of medications on the fetus, emphasizing the importance of clinical acumen and close monitoring 1.

If pregnant or breast-feeding, ask a health professional before use. The FDA drug label does not answer the question.

Recommendations for Cough in the First Trimester Caused by URI
For a cough in the first trimester caused by an Upper Respiratory Infection (URI), several options can be considered based on available evidence:
- Guaifenesin, an expectorant, can help loosen mucus in the airways, making coughs more productive 2.
- Studies have shown that guaifenesin inhibits cough reflex sensitivity in subjects with URI, potentially providing relief 3, 4.
- The combination of guaifenesin with other agents, such as benzonatate, may also be effective in suppressing capsaicin-induced cough 4.
- Extended-release formulations of guaifenesin have been found to be safe and well-tolerated in patients with cough, thickened mucus, and chest congestion associated with URI 5.
- Patient-reported outcomes have been used to assess the efficacy of extended-release guaifenesin for treating acute respiratory tract infection symptoms, with promising results 6.
Key Considerations
When considering treatment options for a cough in the first trimester caused by URI:
- It is essential to consult with a healthcare provider to determine the best course of treatment.
- Guaifenesin has a well-established safety and tolerability profile in adult and pediatric populations 2, 5.
- The efficacy of guaifenesin in acute respiratory infections is being further studied to optimize its effectiveness 2, 6.
