From the Research
For pregnant individuals, dextromethorphan (found in medications like Robitussin DM) is generally considered the safest cough suppressant option. The recommended dose is typically 10-30 mg every 4-6 hours as needed, not exceeding 120 mg in 24 hours. Always use the lowest effective dose for the shortest duration possible. Before taking any medication, consult with your healthcare provider first, as individual circumstances may affect recommendations. Non-medication approaches should be tried initially, including staying hydrated, using a humidifier, consuming honey (1-2 teaspoons as needed), and gargling with salt water. Avoid combination products that contain additional ingredients like antihistamines, decongestants, or alcohol. Dextromethorphan works by suppressing the cough reflex in the brain rather than addressing the underlying cause. While it's considered relatively safe during pregnancy, it's essential to treat only troublesome coughs that interfere with sleep or daily activities, as coughing serves the important function of clearing airways of irritants and mucus.
Some studies suggest that honey may be an effective alternative to dextromethorphan for cough suppression, particularly in children 2. However, the evidence for honey's effectiveness in pregnant individuals is limited. A study published in 2018 found that honey probably reduces cough frequency better than no treatment or placebo in children, and may have a similar effect as dextromethorphan in reducing cough frequency 2. Nevertheless, dextromethorphan remains the most widely recommended and studied cough suppressant for pregnant individuals.
It's crucial to note that codeine, a commonly used antitussive, may not be the best option for pregnant individuals due to its potential risks and side effects 3. Additionally, other over-the-counter cough medications, such as antihistamines and decongestants, may not be effective in relieving cough symptoms and can have adverse effects 4, 5. Therefore, it's essential to consult with a healthcare provider before taking any medication during pregnancy.
In terms of non-medication approaches, staying hydrated, using a humidifier, and consuming honey can help alleviate cough symptoms. Gargling with salt water can also help soothe a sore throat and reduce coughing. These approaches can be used in conjunction with dextromethorphan or as an alternative for mild coughs.
Key points to consider:
- Dextromethorphan is generally considered the safest cough suppressant option for pregnant individuals.
- Honey may be an effective alternative to dextromethorphan for cough suppression, particularly in children.
- Codeine and other over-the-counter cough medications may not be the best options for pregnant individuals due to potential risks and side effects.
- Non-medication approaches, such as staying hydrated and using a humidifier, can help alleviate cough symptoms.
- Consult with a healthcare provider before taking any medication during pregnancy.
