Swallowroot and Doxylamine Succinate, Pyridoxine Hydrochloride

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Doxylamine Succinate, Pyridoxine Hydrochloride and Swallowroot in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How to take them

Some Doxylamine Succinate, Pyridoxine Hydrochloride Products Have a Food Rule — Swallowroot Should Not Break It

At least one FDA label for a product containing Doxylamine Succinate, Pyridoxine Hydrochloride says to take it on an empty stomach. Most supplements — Swallowroot included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Doxylamine Succinate, Pyridoxine Hydrochloride on its own and move Swallowroot to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Doxylamine Succinate, Pyridoxine Hydrochloride products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Take on an empty stomach with a glass of water [ see Clinical Pharmacology (12.3) ].

From the Dosage and Administration section of the FDA label we read for Doxylamine Succinate, Pyridoxine Hydrochloride — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

About Swallowroot

What is Swallowroot?

  • Digestive complaints
  • General tonic and appetite stimulant
  • Blood purifier in folk medicine
  • Antimicrobial and food preservative
  • Cooling drink in hot weather

Swallowroot (Decalepis hamiltonii) is a root used in South Indian folk medicine and as a food flavoring, often pickled or made into a cooling drink. Modern scientific evidence for its health benefits in people is very limited, resting mostly on laboratory and animal studies, so its effectiveness is not proven. If you are considering it, talk with your pharmacist or doctor first, especially during pregnancy or breastfeeding.

Decalepis hamiltonii · Apocynaceae · Roots and root tubers · Dried root, root powder, pickles, syrups, and traditional decoctions

An interaction check asks whether these two react with each other — it does not ask whether Swallowroot is a good idea for someone in your situation. Here is what our Swallowroot record says about it on its own.

Swallowroot: dosing

There is no established standardized dose for Swallowroot. Traditional use varies widely depending on whether it is taken as a pickle, a drink, or a powder.If you choose to use a commercial product, follow the directions on the label and do not exceed them.

About Doxylamine and Pyridoxine

What Is Doxylamine and Pyridoxine Used For?

Brand names: Diclegis, Bonjesta

Doxylamine and pyridoxine is indicated for the treatment of nausea and vomiting of pregnancy in women who do not respond to conservative management. This applies to the delayed-release tablets (including Diclegis and the generic doxylamine succinate and pyridoxine hydrochloride delayed-release tablets) as well as to Bonjesta, the extended-release tablet formulation.

None of these products have been studied in women with hyperemesis gravidarum (severe, persistent vomiting in pregnancy), so their use in that setting is not established.
