What Actually Helps With Pregnancy Nausea? Here's What Works
If you're reading this while fighting off waves of nausea or wondering how you'll make it through another workday feeling this way, first, you have plenty of company. And second, you do not have to tough it out.
Pregnancy nausea and vomiting affects up to 90% of pregnant women in some form during the first trimester. For many, it's manageable with a few adjustments. For others, it becomes debilitating. Either way, there are real, evidence-based options and no one should be told to just push through it.
Watch Dr. Monique shares what actually worked for her personally — and what your provider can offer when symptoms get serious:
Why Pregnancy Nausea Happens
The exact cause of nausea and vomiting in pregnancy (NVP) isn't fully understood, but hormonal changes, particularly the rapid rise of human chorionic gonadotropin (hCG), are the most widely cited factor. hCG peaks during the first trimester, which tracks closely with when nausea tends to be most intense.
Symptoms typically begin between weeks 4 and 9, peak around weeks 7 to 12, and resolve for most women by week 16. However, about 20% of women experience symptoms beyond the first trimester, and for a small percentage, nausea persists throughout the entire pregnancy.
Other factors that can worsen symptoms include fatigue, stress, strong smells, heat, an empty stomach, and certain foods.
Integrative modalities that may help with nausea
Ginger: Many options for taking ginger. ½ teaspoon freshly grated ginger in tea. Ginger chews. 250 mg capsules up to 4 times a day. There are many studies that demonstrate ginger being effective for nausea.
Peppermint tea can soothe nausea and reduce gastric spasm. If you are experiencing reflux it may worsen your symptoms.
Acupressure: this is a point on your wrist: P6, that when pressure is applied it can relieve nausea. You can purchase a wristband such as Sea-bands or learn how to apply pressure yourself.
Acupuncture: Is safe and pregnancy and many studies showing it is effective for nausea.
Guided imagery, breathing exercises and yoga: help with supporting your autonomic regulation (reducing stress, increasing calm) which can help reduce intensity of the nausea.
The First Line: Vitamin B6 and Doxylamine
The most well-studied and widely recommended starting point for pregnancy nausea is the combination of Vitamin B6 (pyridoxine) and doxylamine.
Dr. Monique used this combination herself. When she was pregnant, she bought them separately, Vitamin B6 as a supplement and doxylamine from an over-the-counter sleep aid. Today, these two ingredients come combined in prescription formulations specifically approved for pregnancy nausea: Diclegis and Bonjesta.
Here's how they work:
Vitamin B6 (pyridoxine) reduces the severity of nausea. A typical starting dose is 10 to 25 milligrams taken up to three times daily. It's safe, well-tolerated, and often recommended as the first step even before adding doxylamine.
Doxylamine is an antihistamine that enhances the anti-nausea effect and also supports sleep, which is helpful, because fatigue makes nausea significantly worse. The main side effect is drowsiness, which is why Dr. Monique took hers at night or first thing in the morning, before the day's demands kicked in.
Diclegis and Bonjesta combine both ingredients in a delayed-release formulation, designed so the medication is active in your system when you need it most. These are the only FDA-approved medications specifically for nausea and vomiting of pregnancy, and they work best when taken consistently rather than only when symptoms flare.
What If That's Not Enough?
For some women, the B6 and doxylamine combination doesn't fully control symptoms. In those cases, your provider has additional options. Dr. Monique mentions several by brand name, because, as she says, the brand names are frankly easier to remember:
Zofran (ondansetron) is one of the most commonly used medications for more severe pregnancy nausea. It works by blocking serotonin receptors involved in triggering the vomiting reflex. It's widely used, though your provider will weigh your individual situation before recommending it.
Phenergan (promethazine) is an antihistamine and anti-nausea medication that has been used in pregnancy for decades, with a well-established safety profile. It's particularly effective for severe symptoms and is available in oral, rectal, and injectable forms.
Reglan (metoclopramide) helps by speeding up stomach emptying, which can reduce nausea in women whose symptoms are related to delayed digestion. It's typically used when other options haven't worked sufficiently.
Dramamine (dimenhydrinate) is another antihistamine option, available over the counter, that has been used safely in pregnancy. It's more commonly used for milder symptoms or as an occasional option.
These medications can be taken as needed, during particularly bad stretches, or on a consistent schedule for women with more severe, persistent symptoms. Your provider will help determine the right approach based on how much your nausea is affecting your daily functioning and nutrition.
The Pre-Conception Tip You Might Not Have Heard
Here's something Dr. Monique wants every woman planning a pregnancy to know: starting a prenatal vitamin before you conceive may actually reduce your chances of developing severe nausea and vomiting once you're pregnant.
Some studies suggest that women who begin taking a multivitamin or prenatal vitamin in the weeks before conception experience less severe NVP symptoms in the first trimester. The exact mechanism isn't fully established, but the B vitamins, particularly B6, are thought to play a role.
If you're in the planning stage, this is one of the simplest things you can do to set yourself up well. Our pre-conception counseling visits are a great opportunity to talk through exactly these kinds of steps: what to start, what to adjust, and how to give your pregnancy the best foundation from the very beginning.
Dietary Adjustments
When nausea is mild, diet adjustments may be adequate. If medications are needed, they work best when supported by practical dietary habits.
Eat small, frequent meals. An empty stomach worsens nausea significantly. Eating something small every one to two hours, even if it's just crackers, keeps your blood sugar stable and gives stomach acid something to work on.
Keep crackers by your bed. Eating a few crackers before you even sit up in the morning can reduce that early-morning nausea spike.
Choose bland, easy-to-digest foods. Bananas, toast, plain rice, applesauce, and broth are gentle on a sensitive stomach. Avoid greasy, spicy, or strongly aromatic foods, which can trigger nausea in many women.
Prioritize protein. High-protein foods, nuts, eggs, yogurt, chicken, help stabilize blood sugar and have been shown to reduce the severity of nausea symptoms.
Stay hydrated. Dehydration intensifies nausea and vomiting. Sip fluids throughout the day rather than drinking large amounts at once which can overdistend your stomach and cause nausea. Cold beverages, ginger tea, and broth are often better tolerated than plain water when nausea is at its worst.
Avoid strong smells. Heightened smell sensitivity is real during pregnancy, and certain odors can trigger immediate nausea. Know your triggers and avoid them where you can.
While these dietary strategies can help many women manage mild pregnancy nausea, they may not be enough for everyone. If nausea or vomiting becomes severe, persistent, or makes it difficult to eat or drink, contact your healthcare provider to discuss safe and effective treatment options.
When Does Pregnancy Nausea End?
For most women, nausea peaks around weeks 8 to 10 and begins to ease by weeks 12 to 14. By the end of the first trimester, the majority of women experience significant improvement.
That said, about one in five women continues to have symptoms into the second trimester, and a smaller group experiences nausea throughout the entire pregnancy.
When Nausea Becomes Something More Serious
There is a more severe form of pregnancy nausea called hyperemesis gravidarum (HG), characterized by persistent, intense vomiting multiple times a day that leads to dehydration, weight loss, and nutritional deficiency. HG affects less than 2% of pregnant women, but when it occurs, it is a medical condition that requires treatment, not willpower.
Seek care promptly if you:
Cannot keep any fluids down for 24 hours or more
Are vomiting more than three to four times per day
Are losing weight
Feel dizzy, faint, or severely weak
Notice dark-colored urine (a sign of dehydration)
HG may require intravenous fluids, medication, and in some cases, hospitalization. It is not something you should manage alone.
You Don't Have to Figure This Out By Yourself

Frequently Asked Questions
Is it safe to take Zofran during pregnancy?
Zofran (ondansetron) is commonly used for pregnancy nausea, but like all medications during pregnancy, it should only be taken under the guidance of your provider, who can evaluate your specific situation and discuss any relevant considerations.
Can I take Unisom and B6 without a prescription?
Yes, doxylamine (found in Unisom SleepTabs) and Vitamin B6 can be purchased separately over the counter. However, talk to your provider before starting any medication regimen during pregnancy so they can confirm the appropriate doses and timing for you.
Does morning sickness mean my baby is healthy?
Research does suggest that women who experience nausea and vomiting in pregnancy tend to have slightly better pregnancy outcomes on average, which many believe reflects a robust, active placenta. But not experiencing nausea doesn't mean anything is wrong, and severe, untreated nausea is never good for mother or baby.
