OTC Cough Syrup for Breastfeeding Mothers
For breastfeeding mothers needing OTC cough syrup, dextromethorphan (DM) is the preferred cough suppressant, and products containing pseudoephedrine with triprolidine are first-line choices for combination cold/cough products, though single-ingredient products are safer than combinations. 1
Recommended Safe Ingredients
Cough Suppressants
- Codeine is considered compatible with breastfeeding by the American Academy of Pediatrics and is acceptable for short-term use as a cough suppressant, though dextromethorphan is generally preferred for OTC use 1
- Dextromethorphan (DM) is widely available OTC and transfers minimally into breast milk, making it a practical first choice 1
Decongestants and Antihistamines
- Pseudoephedrine and triprolidine should be first-line choices for combination products, as both are considered compatible with breastfeeding by the American Academy of Pediatrics and achieve only low levels in breast milk 1
- Loratadine has been studied in humans and shows low transfer to breastfed infants, making it an acceptable antihistamine option 1
Critical Timing and Dosing Strategy
- Take medication immediately after breastfeeding to minimize infant exposure, as peak milk drug concentrations typically occur 1-2 hours following oral medication 2, 1
- Use the lowest effective dose for the shortest duration necessary 1, 3
- Time medication before the infant's longest sleep period when possible 3
Products to Avoid
Combination Products
- Avoid multi-ingredient combination products that contain unnecessary ingredients—single-ingredient products are preferable to minimize infant exposure 1
- Many liquid cough and cold products contain alcohol, which should be avoided or minimized 1
- Products containing aspirin should be avoided, as aspirin has been associated with significant negative effects in nursing infants 1
Ingredients Requiring Caution
- Products with high alcohol content should be avoided 1
- Aspirin-containing products are not recommended due to potential adverse effects 1
Infant Monitoring Requirements
- Watch for paradoxical CNS stimulation (irritability, poor sleep) from antihistamines in the infant 1
- Monitor for irritability and insomnia from decongestants 1
- Observe for any uncharacteristic symptoms or changes in feeding patterns 4, 2
- Premature or compromised infants face higher risk and require closer monitoring 5
Common Pitfalls to Avoid
- Do not assume pregnancy-safe medications are automatically safe for breastfeeding—a drug safe during pregnancy may not be safe for the nursing infant 5
- Avoid taking medication right before breastfeeding, as this maximizes infant exposure during peak maternal drug levels 2
- Do not use long-acting formulations when shorter-acting alternatives are available, as drugs with short half-lives minimize accumulation risk 2
- Never discontinue breastfeeding without consulting reliable sources first—most medications are compatible with continued breastfeeding 3, 6
