From the Guidelines
Treatment for pregnancy nausea should start with lifestyle changes, including eating small, frequent meals, avoiding triggers, and consuming ginger products, and if necessary, progress to medication options such as vitamin B6 and doxylamine, with ondansetron, metoclopramide, or promethazine considered for more severe cases, as recommended by the most recent guidelines 1. The approach to managing pregnancy nausea involves a stepwise treatment plan. Initially, diet and lifestyle modifications are recommended, such as reducing spicy, fatty, acidic, and fried foods to alleviate heartburn, and eating small, frequent, bland meals, like the BRAT diet, to help with nausea and vomiting of pregnancy (NVP) 1.
- Identifying and avoiding specific triggers, such as strong odors or certain activities, can also be beneficial.
- Consuming ginger products, such as tea, candies, or capsules containing 250mg four times daily, has natural anti-nausea properties and can be helpful.
- If symptoms persist or are severe, therapeutic options include vitamin B6 (pyridoxine, 10–25 mg every 8 hours) and ginger, as recommended by the American College of Obstetricians and Gynecologists (ACOG) 1.
- For more severe cases, H1-receptor antagonists like doxylamine, which is US Food and Drug Administration–approved and recommended by ACOG for persistent NVP refractory to non-pharmacologic therapy, can be considered 1.
- Other prescription antiemetics such as promethazine, metoclopramide, or ondansetron may be used under medical supervision for more severe cases, with the understanding that while they are effective, they carry potential risks and side effects, as discussed in recent studies 1. The severity of vomiting during pregnancy can be quantified with a scoring system, such as the Motherisk Pregnancy Unique Quantification of Emesis score, to guide the intensity of treatment needed 1. Early intervention and treatment of NVP may help prevent progression to hyperemesis gravidarum (HG), emphasizing the importance of prompt and appropriate management 1.

From the Research
Treatment Options for Pregnancy Nausea
- The treatment options for pregnancy nausea include lifestyle and dietary changes, as well as pharmacologic therapy 2, 3.
- For mild cases of nausea and vomiting, lifestyle and dietary changes may be sufficient to resolve symptoms 2, 3.
- Pharmacologic therapy, such as vitamin B6, doxylamine, and antihistamine (H(1)) blockers, may be effective for treating nausea and vomiting of pregnancy 4, 5, 6.
- The combination of doxylamine and pyridoxine (vitamin B6) has been shown to be safe and effective for treating nausea and vomiting of pregnancy 4, 5, 6.
- Other medications, such as metoclopramide, droperidol, and ondansetron, may also be effective, but safety data are insufficient to recommend them as first-line agents 5.
- Corticosteroids may not be as beneficial as first thought and may have a small teratogenic risk 5.
Safety and Effectiveness of Treatment Options
- Vitamin B6 has been established as harmless during pregnancy in doses up to 40-60mg/day, mainly in combination with doxylamine 4.
- Doxylamine succinate/pyridoxine hydrochloride (Diclegis) has been approved by the U.S. Food and Drug Administration for the treatment of nausea and vomiting of pregnancy 6.
- The safety and effectiveness of pharmacologic therapy for nausea and vomiting of pregnancy should be carefully considered, and treatment should be individualized based on the severity of symptoms and the woman's perception of her symptoms 2, 3.
