The bottom line No known interaction

We found no known interaction between Hollyhock and Thalidomide in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Hollyhock and Thalidomide

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 Thalidomide and Hollyhock 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.

Hollyhock safety at a glance

Hollyhock overall Use caution Generally considered gentle, but human safety data are limited.
Pregnancy Avoid Not enough safety information, so it is best avoided.
Breastfeeding Avoid No reliable safety data during breastfeeding, so avoid use.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Thalidomide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Thalidomide is filed under 2 classifications — immunosuppressants, oral drugs. Hollyhock has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Thalidomide’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Thalidomide’s Own FDA Label Lists

This is not an interaction — none of it involves Hollyhock. These are the most notable effects listed in the ADVERSE REACTIONS section of Thalidomide’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Muscle weakness Worth acting on
  • Low potassium Worth acting on
  • A slow heartbeat Worth acting on
  • Blood clots Worth acting on
  • High blood sugar Worth acting on
  • Fainting Worth acting on
  • Confusion Worth acting on
  • Seizures Worth acting on
  • Low mood Worth acting on
  • A low platelet count Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Thalidomide. Read the label on DailyMed › Hollyhock’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Hollyhock side to compare — that is a limit of the record, not a statement that Hollyhock has no side effects.

From our pharmacist’s overview on the Thalidomide page

“Thalidomide (Thalomid) works in part by quieting the immune system, which is exactly why most of the supplements on this page concern me. The large majority are herbs and extracts marketed as immune boosters, astragalus being one familiar example, and their theoretical effect is to push back against what thalidomide is trying to accomp…”

About Hollyhock

What is Hollyhock?

  • Sore throat and cough
  • Digestive upset
  • Soothing irritated skin
  • Mild inflammation
  • Urinary discomfort

Hollyhock is a flowering plant in the mallow family that has been used in traditional medicine, mainly as a soothing (demulcent) remedy for the throat, gut, and skin. Solid human studies are very limited, so its benefits are not well proven. It is generally considered gentle, but you should still talk to a pharmacist or doctor before using it, especially if you are pregnant or breastfeeding.

Alcea rosea · Malvaceae · Flowers, leaves, and roots · Tea, dried flowers, extracts, topical preparations

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

Hollyhock: dosing

There is no well-established, standardized dose for hollyhock. Traditional use most often involves a tea made from the dried flowers or leaves.Because products vary in strength and form, the safest approach is to follow the directions on the product label and not exceed the recommended amount.

About Thalidomide

What Is Thalidomide Used For?

Brand name: Thalomid

Thalomid (thalidomide capsules) is approved for two uses. First, it is used in combination with dexamethasone to treat newly diagnosed multiple myeloma — a cancer of plasma cells in the bone marrow.

Second, Thalomid is used on its own to treat the skin symptoms of moderate to severe erythema nodosum leprosum (ENL), a painful inflammatory reaction that can occur in people with leprosy. It can also be used as ongoing maintenance therapy to prevent ENL from coming back. Note: Thalomid is not approved as the sole treatment for ENL when moderate to severe nerve inflammation (neuritis) is also present.
