From the Research
The safest cough syrup option during pregnancy is one containing dextromethorphan, such as Robitussin DM, as it has been shown to not increase the rates of major malformations above the expected baseline rate of 1% to 3% 1. When considering cough syrup options during pregnancy, it's essential to prioritize the safety of both the mother and the developing baby.
- Dextromethorphan is generally considered safe for use during all trimesters of pregnancy, with a typical dose of 10-30 mg every 4-6 hours as needed for cough suppression.
- Guaifenesin, another common ingredient in cough syrups, is also considered safe, with a usual dose of 200-400 mg every 4 hours to help thin mucus.
- However, it's crucial to avoid cough syrups containing alcohol, pseudoephedrine, phenylephrine, or codeine, as these ingredients may pose risks to the developing baby.
- Non-medication approaches like staying hydrated, using a humidifier, and consuming honey (not for children under 1 year) can also help manage cough symptoms during pregnancy, as shown in a study comparing the effect of honey, dextromethorphan, and diphenhydramine on nightly cough and sleep quality in children and their parents 2. Before taking any medication during pregnancy, even over-the-counter options, it's best to consult with your healthcare provider first, as they can provide personalized advice based on your specific health situation and pregnancy stage.
- Always check that the product you choose contains only the recommended ingredients and nothing else.
- The study on the safety of dextromethorphan in pregnancy 1 provides strong evidence for its safety, and it is a more recent and higher-quality study compared to the other available evidence 3, 2.
