Occasional doses of common over-the-counter motion sickness medications are generally considered acceptable while breastfeeding. Ginger is the simplest starting point since it carries virtually no risk, but if you need something stronger, antihistamine-based options like dimenhydrinate and meclizine can work when used in single or short-term doses. The key is keeping use occasional and being mindful of timing.
Ginger: The Lowest-Risk Option
Ginger has a long track record for treating nausea and motion sickness, and the FDA classifies it as “generally recognized as safe” as a food ingredient, including during lactation. Very limited data exist specifically on ginger in nursing mothers, but no safety concerns have been identified. Mild side effects like heartburn or stomach discomfort are occasionally reported in adults.
Ginger capsules, ginger chews, ginger tea, and crystallized ginger are all reasonable forms to try. For motion sickness, taking it 30 to 60 minutes before travel tends to work best. As a bonus, several small studies in postpartum women found that ginger may actually support milk production rather than hinder it.
Dimenhydrinate (Dramamine)
Dimenhydrinate is the active ingredient in original Dramamine and one of the most widely used motion sickness remedies. It’s a first-generation antihistamine, and while formal studies in breastfeeding women are limited, one older study measured milk levels after a dose and found the drug was undetectable in half the women tested. In the others, levels were low and dropped further by five hours after the dose.
In a telephone follow-up study of mothers taking various antihistamines, about 10% reported mild irritability or colicky symptoms in their infants, and 1.6% reported drowsiness. None of these reactions required medical attention. Among mothers specifically taking dimenhydrinate, irritability was reported in one out of seven exposed infants. These numbers are reassuring for occasional use, though you should watch your baby for unusual sleepiness or fussiness.
Meclizine (Bonine, Dramamine Less Drowsy)
Meclizine is another over-the-counter antihistamine sold under brand names like Bonine and Dramamine Less Drowsy. No published data exist on how much meclizine transfers into breast milk, but based on its drug class, occasional doses are considered probably acceptable during breastfeeding. It tends to cause less drowsiness than dimenhydrinate in the mother, which can be a practical advantage when you’re caring for an infant.
The same caution applies here as with other antihistamines: large doses or prolonged use could potentially affect your baby or reduce milk supply, especially if your milk supply isn’t fully established yet (generally before six to eight weeks postpartum).
What About Prescription Options
If over-the-counter options aren’t enough, two prescription medications come up most often for motion sickness.
The scopolamine patch (Transderm Scop) does pass into breast milk. The FDA labeling notes that no data exist on its effects on a breastfed infant or on milk production, and it advises discussing infant feeding plans with your provider before using it. It’s not ruled out, but the lack of safety data means it’s a conversation to have rather than a decision to make on your own.
Promethazine (Phenergan) is sometimes prescribed for severe nausea. Occasional short-term use appears to pose little risk to a breastfed infant based on what’s known about similar drugs in its class. However, promethazine can lower prolactin, the hormone that drives milk production. One small study found that women given promethazine during labor experienced a delay of about 14 hours in their milk coming in. For this reason, it’s generally not the preferred choice for nursing mothers, and experts recommend antiemetics without strong antihistamine effects when possible.
Protecting Your Milk Supply
The biggest practical concern with motion sickness medications while breastfeeding isn’t infant exposure. It’s the potential effect on milk production. First-generation antihistamines have a drying effect on secretions (that’s why they also help with runny noses), and there’s a theoretical concern this extends to breast milk. At normal therapeutic doses, antihistamines are unlikely to affect supply once lactation is well established, which typically happens around six to eight weeks postpartum.
Before that point, be more cautious. Avoid combining antihistamines with decongestants like pseudoephedrine, which has a documented effect on reducing milk output. If you’re in the early weeks of breastfeeding and facing a situation where you’ll need motion sickness relief, ginger or acupressure are the safest bets for supply preservation.
Timing Your Dose to Reduce Infant Exposure
If you’re taking dimenhydrinate or meclizine, you can minimize how much reaches your baby by timing the dose right after a feeding or pumping session. This gives the drug time to peak in your bloodstream and begin clearing before the next feed. Based on the limited milk level data available for dimenhydrinate, drug concentrations in milk were already dropping by five hours post-dose, so nursing or pumping just before taking a dose and then waiting as long as practical before the next feed is a reasonable approach.
You don’t need to pump and dump. The amounts that transfer into milk are small, and the reported infant effects are mild and uncommon. Timing is simply an extra layer of caution, not a requirement.
Acupressure Wristbands
Sea-Bands and similar wristbands claim to reduce nausea by pressing on the P6 acupuncture point on the inner wrist. They’re completely safe during breastfeeding since nothing enters your body. However, controlled studies have found that neither acupressure bands nor electrical stimulation bands prevented motion sickness any better than placebo. Some people find them subjectively helpful, and there’s no downside to trying them, but they shouldn’t be your only plan if you’re prone to significant motion sickness.
What to Watch for in Your Baby
If you take any antihistamine-based medication, keep an eye on your infant for unusual drowsiness, difficulty feeding, or increased irritability in the hours after nursing. These effects were reported in a small percentage of infants in survey data and resolved without medical intervention. If your baby seems excessively sleepy, difficult to wake for feedings, or is feeding poorly, that warrants a call to your pediatrician.
