The bottom line No known interaction

Interaction report

Common Stonecrop and Omalizumab

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 Omalizumab and Common Stonecrop 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Common Stonecrop at all — not against Omalizumab, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

Common Stonecrop overall Use caution Limited safety data exist, and internal use can cause irritation, vomiting, and diarrhea.

What to actually watch for

What Common Stonecrop Itself Has Been Linked To

This is not an interaction — nothing below involves Omalizumab. It is the side-effect record for Common Stonecrop on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Common Stonecrop, this list is the first place to look.

Diarrhea / Vomiting Additional detail
“Orally, common stonecrop can cause vomiting and diarrhea when consumed in very large amounts (18).”

Everything above comes from the Natural Medicines adverse-effect record for Common Stonecrop — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Omalizumab’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Omalizumab column appears here.

Everything else you take

See Every Supplement That Interacts With Omalizumab

This page covers Common Stonecrop only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Omalizumab page lists 53 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Active Hexose Correlated Compound (ahcc) (moderate), Alfalfa (moderate), American Ginseng (moderate), Andrographis (moderate) and Ashwagandha (moderate).

By severity: 52 moderate · 1 minor.

From our pharmacist’s overview on the Omalizumab page

“None of the 53 supplements on file for omalizumab (Xolair) carries a major rating, so this is a list to read with steady attention rather than alarm. Xolair treats allergic asthma and chronic hives by calming part of the immune system, and every entry here pulls the other way: these are immune-stimulating products, echinacea and astrag…”

About Common Stonecrop

What is Common Stonecrop?

Wounds and skin irritation
Eczema and other skin conditions
Constipation (laxative use)
Urinary and bladder complaints
High blood pressure (folk use)

Common Stonecrop (Sedum acre) is a small succulent with a long history in European folk medicine, mostly applied to the skin or used as a laxative. There is very little modern scientific evidence to support any of its uses, and the plant can be irritating and may cause vomiting or diarrhea when swallowed, so it should be used with caution and ideally avoided internally.

Sedum acre · Crassulaceae · Above-ground parts (leaves, stems, and flowering tops), used fresh or dried · Fresh plant, dried herb, topical preparations, and rarely teas or tinctures

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

Common Stonecrop: dosing

There is no established or standardized dose for Common Stonecrop. Because it has not been studied in proper clinical trials, safe and effective amounts are simply not known.If you choose to use a commercial product, follow the directions on the label and do not exceed them.

From our Common Stonecrop monograph — the full record covers uses, side effects and every documented interaction.

Medication

About Omalizumab Injection

What Is Omalizumab Injection Used For?

Brand name: Xolair

Xolair is used for several allergy-driven conditions. It treats moderate to severe persistent asthma in adults and children 6 and older whose symptoms aren't controlled by inhaled steroids alone and who test positive for a year-round airborne allergen. It is also used as an add-on maintenance treatment for chronic rhinosinusitis with nasal polyps (ongoing sinus inflammation with polyp growths) in adults 18 and older who haven't responded well to nasal corticosteroids.

Xolair is also approved to reduce allergic reactions — including anaphylaxis — from accidental food exposure in adults and children aged 1 and older with IgE-mediated food allergy. It must be used alongside strict food avoidance, and it is not a substitute for emergency treatment like epinephrine. Finally, Xolair treats chronic spontaneous urticaria (persistent hives with no identified trigger) in adults and adolescents 12 and older who still have symptoms despite antihistamine treatment.
