More than 70% of pregnant people experience morning sickness - nausea and vomiting that can hit at any time of day. It’s not just a nuisance; for many, it disrupts sleep, work, and daily life. The good news? There are safe, proven ways to manage it - from simple over-the-counter options to prescription treatments backed by decades of research. But not all remedies are created equal. Some work better than others. Some carry risks you might not know about. And some are completely off-limits.
What’s Actually Safe During Pregnancy?
When it comes to treating morning sickness, safety isn’t just a buzzword - it’s the foundation. The American College of Obstetricians and Gynecologists (ACOG) says the first-line treatment is a combination of pyridoxine (vitamin B6) and doxylamine. Both are available over the counter. Pyridoxine comes in 10-25 mg tablets. Doxylamine is the active ingredient in Unisom SleepTabs (12.5 mg per tablet). Together, they’re effective for most people, and they’ve been studied in more than 200,000 pregnancies with no link to birth defects.
Even though this combo has been around since the 1950s, it was pulled off the market in the U.S. in 1983 due to lawsuits - not science. In 2013, it came back as Diclegis, a delayed-release prescription version. It’s the same ingredients, just formulated to release slowly so you don’t get hit with drowsiness all at once. Studies show it reduces nausea and vomiting by 70% compared to placebo. And it’s classified as Pregnancy Category A - the highest safety rating possible - meaning there’s no evidence of harm to the fetus in controlled human studies.
OTC Options That Actually Work
You don’t need a prescription to start feeling better. Here are the most effective OTC choices, backed by clinical data:
- Pyridoxine (vitamin B6): Take 10-25 mg three times a day. The FDA says up to 200 mg daily is safe during pregnancy. It’s cheap - often under $5 for a month’s supply - and rarely causes side effects.
- Doxylamine succinate (Unisom): Take 12.5 mg at bedtime. It can make you sleepy, which is why many use it as a nighttime aid. If nausea continues, you can add a second dose in the afternoon. About 65% of users report drowsiness, but most adjust within a few days.
- Ginger: Studies show 1,000 mg of dried ginger root per day reduces nausea by 32% compared to placebo. You can get it in capsules, chews, tea, or crystallized form. Ginger is labeled ‘Generally Recognized As Safe’ (GRAS) by the FDA. One study found it worked better than placebo for nausea, though it didn’t significantly reduce vomiting. Still, many find it helpful enough to use alongside other treatments.
- Acupressure wristbands: These target the P6 point on the inner wrist - three finger-widths above the crease. A Cochrane Review of over 1,100 pregnant people found they reduced vomiting episodes by 2.2 per day. They’re not a magic fix, but they’re drug-free, safe, and cost under $20. Some users swear by them; others notice little change. Worth trying if you want to avoid medication early on.
Prescription Treatments: When OTC Isn’t Enough
If you’ve tried OTC options for 3-5 days and still can’t keep food or water down, it’s time to talk to your provider. Diclegis is the gold standard. The dosing is specific: one tablet in the morning, one in the afternoon, and two at bedtime. It takes 3-5 days to build up in your system. Most users report improvement by day 7. It’s more expensive than OTC versions - around $250 a month without insurance - but many pharmacies offer coupons that bring it down to $50 or less.
Another option is ondansetron (Zofran). It’s highly effective - 70-80% of users get relief. But it’s not first-line. Why? Because some studies have raised questions about a possible small increase in oral clefts, though the largest study - tracking 1.2 million pregnancies - found no significant risk. The FDA hasn’t issued a warning, but experts like Dr. Gideon Koren from the Motherisk Program say it should be reserved for cases where other treatments fail. It costs about $350 a month without insurance and can cause headaches or constipation.
Promethazine (Phenergan) is another prescription choice. It comes as a pill, suppository, or injection. It works quickly, but it causes drowsiness in 15% of users and can irritate veins if given by injection. It’s often used when someone can’t keep pills down - the rectal form bypasses the stomach entirely.
What to Avoid
Not every remedy you hear about is safe. Avoid these:
- Marijuana or CBD: ACOG explicitly warns against using marijuana for morning sickness. There’s no solid data on safety, and studies link prenatal cannabis use to lower birth weight and potential developmental issues.
- Unregulated herbal supplements: Things like peppermint, chamomile, or licorice root aren’t tested in pregnancy. Some can stimulate contractions or affect hormone levels.
- High-dose vitamin B6 without medical advice: While up to 200 mg is safe, doses over 500 mg daily may cause nerve damage. Always check with your provider before going above 25 mg per dose.
How to Use These Treatments Together
The most successful approach combines lifestyle changes with medication - not one or the other.
Start with diet and habits:
- Eat small meals every 2-3 hours. Aim for 45-60 grams of carbs and 15-20 grams of protein each time.
- Choose cold foods over hot ones - they’re less likely to trigger nausea from smell.
- Avoid greasy, spicy, or strong-smelling foods.
- Keep crackers by your bed. Eat one before getting up in the morning.
- Stay hydrated. Sip water, electrolyte drinks, or ginger tea slowly throughout the day.
Then layer in remedies:
- Day 1-2: Try ginger chews and acupressure bands.
- Day 3: Add pyridoxine 10 mg three times a day.
- Day 4: If nausea continues, add doxylamine 12.5 mg at bedtime.
- Day 5-7: If still struggling, ask your provider about Diclegis or ondansetron.
Many women find that using acupressure bands with ginger and B6 reduces their need for stronger meds. One Reddit user wrote: “Ginger chews saved me during first trimester - but I needed Diclegis for full relief.” That’s not unusual.
Cost, Access, and Real-World Challenges
Price matters. Generic pyridoxine and doxylamine cost $15-30 a month. Diclegis runs $200-300 without insurance. But many insurers cover it, and the manufacturer offers savings cards that can cut the cost to $20 or less. GoodRx shows the generic combo can be as low as $18.99 at Walmart or CVS.
Access isn’t equal. A 2022 study found only 42% of Medicaid patients received guideline-recommended care, compared to 89% of privately insured patients. If you’re struggling to afford treatment, ask your provider about samples or patient assistance programs.
Some women can’t tolerate pills at all. That’s where suppositories like promethazine come in. Others can’t sleep because of nausea. That’s where nighttime doxylamine helps. There’s no one-size-fits-all - but there is a safe path forward.
When to Call Your Doctor
Most morning sickness fades by week 14. But if you’re losing weight, can’t keep fluids down, or notice dark urine or dizziness, you may have hyperemesis gravidarum - severe nausea that requires medical care. The updated ACOG guideline now defines it as just 3% weight loss plus ketones in urine, not 5%. That means earlier help is possible.
Don’t wait until you’re dehydrated. If you’ve tried OTC remedies for five days and feel worse, call your provider. You don’t have to suffer through your first trimester. Safe, effective help is out there.
Is it safe to take Unisom and vitamin B6 together during pregnancy?
Yes. The combination of doxylamine (in Unisom) and pyridoxine (vitamin B6) is the first-line treatment recommended by ACOG and has been studied in over 200,000 pregnancies with no increased risk of birth defects. The FDA approves this combo for use in pregnancy, and it’s the same active ingredients found in the prescription drug Diclegis. Take 10-25 mg of B6 three times daily and 12.5 mg of doxylamine at bedtime, or as directed by your provider.
Can I take ginger supplements while pregnant?
Yes. Ginger is classified as Generally Recognized As Safe (GRAS) by the FDA. Studies show 1,000 mg per day of dried ginger root reduces nausea by about 32%. You can take it as capsules, chews, tea, or candy. Avoid large doses over 1,500 mg daily unless approved by your provider, as high amounts may affect blood clotting. Ginger is safest when taken after eating to avoid stomach irritation.
Is Diclegis better than Unisom and B6?
Diclegis contains the same ingredients as Unisom and vitamin B6, but it’s formulated to release slowly, reducing drowsiness and improving symptom control. In clinical trials, Diclegis reduced nausea and vomiting by 76% compared to 53% with B6 alone. It’s more expensive, but many find it more effective and easier to tolerate. If you’re already using Unisom and B6 and it’s working, there’s no need to switch - but if you’re still struggling, Diclegis may be worth discussing with your provider.
Why is ondansetron not a first-choice treatment?
Ondansetron (Zofran) works well, but it’s not first-line because some studies have raised questions about a possible small increase in oral clefts, though larger studies show no significant risk. Experts recommend it only after safer options like B6, doxylamine, or Diclegis have failed. It’s also more expensive and can cause headaches or constipation. For most people, the proven safety of doxylamine-pyridoxine makes it the better starting point.
Are acupressure bands worth trying?
Yes, especially if you want to avoid medication early on. A Cochrane Review found they reduced vomiting by 2.2 episodes per day compared to placebo. They’re safe, drug-free, and cost under $20. They work best when worn continuously and properly placed - three finger-widths above the wrist crease, between the two tendons. Some users find them helpful for mild nausea, while others need to combine them with ginger or B6. They’re a low-risk option worth testing.
Final Thoughts
Morning sickness is common, but it doesn’t have to be normal. You don’t have to push through it. There are safe, effective options - from a $15 bottle of B6 to a prescription that can turn your day around. Start simple. Track what works. Talk to your provider. And remember: you’re not alone. Millions of people have been here. And every one of them found a way through - with science, support, and the right tools.
