Vitamin B6 and an over-the-counter combination have real evidence behind them for nausea. Today you write the question for your provider before you try either.

Size this week
about the size and shape of a pea
Length this week

A woman in a loose shirt at a bathroom mirror in morning light, writing a note on her phone, a plain unlabeled bottle on the shelf behind her out of focus.

Six weeks and two days. Yesterday was ginger. Today is the next step up, the one with a label on it, and the rule that comes before it.

Your baby

A single green pea resting on a fingertip, close up, soft window light.

Around 6mm, about the size and shape of a pea, with the ears beginning to take shape (NHS). The reason today's rule exists is one NHS sentence: the baby draws everything it needs from the mother (NHS). What goes into you is on the same supply line.

Your body

Vitamin B6 at 100 mg or less a day has been shown to ease morning sickness, and many providers suggest trying it first (MedlinePlus). Diclegis, a combination of doxylamine and vitamin B6, is FDA-approved for morning sickness (MedlinePlus); the same pairing, doxylamine (sold as Unisom) with B6, is described by MedlinePlus as very effective and safe for pregnancy nausea and available without a prescription (MedlinePlus). The Cochrane review is cooler: only limited evidence supports B6 and doxylamine-pyridoxine for mild or moderate symptoms (Cochrane).

Then the rule, in MedlinePlus's words: "Do not take any medicines for morning sickness without talking with your provider first" (MedlinePlus). The reason is bigger than nausea. Fewer than 10% of medicines approved since 1980 have enough information to determine their safety during pregnancy, because pregnant women are usually excluded from the studies (CDC). Your provider knows your history; a label doesn't.

Try today

  1. The B6 ask

    Time: 5 minutes

    1. Write the question exactly: "Should I try vitamin B6 for nausea, and how much?" (MedlinePlus)

    2. Under it, list what you've already tried: the snack clock, the ginger, the sips between meals. The answer will be better for it.

    3. List everything you already take, prescription and over the counter, vitamins and herbal included. Talk to your providers before starting or stopping any of them (CDC).

    4. Send it to the office today if they take messages, or put it at the top of the first-visit list.

    Make it work:

    If a friend's bottle is already in your bathroom, leave it there until you've asked (MedlinePlus). Asking is a two-line message; it isn't a fuss.

Watch for

  • Normal

    nausea that comes and goes through the day (NHS).

    Call your provider

    if you can't keep any fluids down for over 12 hours, lose more than 5 pounds (2.3 kilograms), feel lightheaded, or see blood in your vomit (MedlinePlus).

  • Normal

    wanting to take what helped someone else.

    Call your provider

    before any medicine for nausea; that's MedlinePlus's rule (MedlinePlus), and the CDC's warning is that online "safe medicine" lists often lack sufficient scientific evidence (CDC).

  • Normal

    tiredness and a few more trips to the bathroom (NHS).

    Call 911

    or go to an emergency room right away for severe chest pain or shortness of breath that does not go away (MedlinePlus).

  • Normal

    a week of small plans and one unanswered question.

    Call your provider

    if you feel like something just isn't right, even if it isn't on any list, and tell every provider you see that you're pregnant (CDC).

For you

You're not alone in the question. About 9 in 10 women report taking some type of medicine during pregnancy (CDC). The hard part isn't needing something; it's the gap between needing it and knowing.

For that gap there's a free line. MotherToBaby gives free, confidential expert answers about medicines in pregnancy, in English or Spanish, by phone at 1-866-626-6847, chat, or email (CDC). It doesn't replace your provider, but it answers on a Sunday.

If you're the partner: your medicine cabinet is the other half of the question. Nothing of yours goes to her without the ask.
