Hollyhock and Captopril

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 Captopril 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 Captopril

Interactions in our licensed database are recorded against drug classes, not just single drug names. Captopril is filed under 5 classifications — including ace inhibitors (aceis), antihypertensive drugs, photosensitizing drugs. Hollyhock has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Captopril’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 Captopril’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 Captopril’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.

  • A stroke or mini-stroke Worth acting on
  • Bleeding in the gut Worth acting on
  • High potassium Worth acting on
  • Low sodium Worth acting on
  • Unsteadiness Worth acting on
  • A heart attack Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Heart failure Worth acting on
  • Fainting Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Captopril. Read the label on DailyMed › Where a percentage is shown, it is the share of 9,625 voluntary FDA FAERS reports for Captopril that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. 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 Captopril page

“Anyone taking captopril (Capoten), an ACE inhibitor for high blood pressure and heart failure, should treat this list with genuine care rather than a quick skim. Most of the ingredients here act on blood pressure itself, some dropping it lower than intended and others, tyramine among them, pushing it back up and working against the med…”

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 Captopril

What Is Captopril Used For?

Brand names: Capoten, Acepril

Captopril tablets are used to treat high blood pressure (hypertension), heart failure, and left ventricular dysfunction (weakened pumping function of the heart) in stable patients after a heart attack. For the heart attack indication, it helps improve survival and reduces the chance of developing full heart failure.

Captopril tablets are also used to slow the progression of diabetic nephropathy (kidney damage caused by diabetes) in people with type 1 (insulin-dependent) diabetes who have retinopathy and significant protein in their urine. It reduces the risk of the kidneys failing to the point of needing dialysis or a transplant.

Most-Reported Side Effects for Captopril

From FAERS, the FDA’s public side-effect reporting system (9,625 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Dyspnea 615 reports
Hypertension 536 reports
Nausea 508 reports
Diarrhea 470 reports
Dizziness 448 reports
