Umckaloabo + Cromolyn Sodium

Cromolyn Sodium brand names: Intal, Novo Cromolyn.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Umckaloabo and Cromolyn Sodium 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Umckaloabo and Cromolyn Sodium

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 Cromolyn Sodium and Umckaloabo 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.

Umckaloabo safety at a glance

Umckaloabo overall Use caution Generally well tolerated for short-term use, but quality and standardization vary by product.
Pregnancy Avoid Safety has not been established, so it is best avoided during pregnancy.
Breastfeeding Avoid There is not enough safety information, so avoid use while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Cromolyn Sodium

Interactions in our licensed database are recorded against drug classes, not just single drug names. Cromolyn Sodium is filed under a single classification — oral drugs. Umckaloabo has documented interactions with 2 drug classes — the most serious being immunosuppressants (moderate) and anticoagulant/antiplatelet drugs (minor) — and none of Cromolyn Sodium’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 to actually watch for

No Interaction Found — But Data Suggests Umckaloabo and Cromolyn Sodium May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. 2 of them are worth acting on rather than waiting out — marked below.

  • Wheezing / Hives Worth acting on reported in 4.1% of FDA reports for Cromolyn Sodium Additional detail

    “Orally, Pelargonium sidoides has been associated with over 34 reports of allergic reactions. Urticaria is the most common reaction but there were also cases of conjunctivitis, rhinitis, and systemic allergic reactions including bronchospasm, dyspnea, tachycardia, and circulatory failure.”

Reported for Umckaloabo but not commonly for Cromolyn Sodium: stomach upset, pancreatitis, an allergic reaction and liver problems.

Effects for Cromolyn Sodium come from the ADVERSE REACTIONS section of its FDA label; effects for Umckaloabo come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 3,585 voluntary FDA FAERS reports for Cromolyn Sodium that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Cromolyn Sodium Is Prescribed For, and What Umckaloabo Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Cromolyn Sodium is a prescription medicine with approved uses on its FDA label. Umckaloabo is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Cromolyn Sodium is prescribed for: Cromolyn sodium inhalation solution is used on a regular, daily basis to help manage bronchial asthma in adults and children two years of age and older. It works best as a preventive medicine — it will not stop an asthma attack that has already started. It can also be used as a single dose taken shortly before exposure to known triggers — such as exercise, cold dry air, animal dander, or environmental pollutants — to help prevent the sudden airway tightening those triggers can cause.

Umckaloabo has been studied for:

  • Asthma studied, not established Umckaloabo has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Umckaloabo for asthma

    It is unclear if oral Pelargonium sidoides extract is beneficial in children with asthma who have an active viral upper respiratory tract infection.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Cromolyn Sodium on your own; if you are taking Umckaloabo for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Umckaloabo

What is Umckaloabo?

Umckaloabo
  • Acute bronchitis
  • Common cold
  • Sinusitis
  • Sore throat
  • Upper respiratory infections

Umckaloabo is a root extract from a South African geranium that is most studied for short-term relief of acute bronchitis and other respiratory infections. Some clinical research suggests it may help symptoms resolve a bit faster, but the quality of evidence is mixed and it is not a cure. Talk to your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have a chronic illness.

Pelargonium sidoides · Geraniaceae · Roots · Liquid extract (drops), syrup, tablets, lozenges

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

Umckaloabo: dosing

There is no single official dose of Umckaloabo for everyone, and the right amount depends on the specific product and its strength. Most research has used standardized extracts taken a few times a day for a short period, usually during an active respiratory infection.Because formulations differ, the safest approach is to follow the directions on the product label and not exceed the recommended amount. Doses for children differ from those for adults.

Taking Umckaloabo and Cromolyn Sodium Together: Common Questions

Is it safe to take Umckaloabo with Cromolyn Sodium?
We do not list a known interaction between Umckaloabo and Cromolyn Sodium. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Umckaloabo and Cromolyn Sodium have any of the same side effects?
Yes — our sources link each of them separately to 4 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are Umckaloabo and Cromolyn Sodium used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Umckaloabo in each. That is a conversation for your prescriber, especially if Cromolyn Sodium is being adjusted to a target.
How was the Umckaloabo and Cromolyn Sodium combination checked?
Interactions in our licensed database are recorded against drug classes. Cromolyn Sodium is filed under 1 classification, and Umckaloabo has documented interactions with 2 drug classes — none of Cromolyn Sodium's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Umckaloabo interact with any other medications?
Yes. Umckaloabo has 241 documented drug interactions in our database — Cromolyn Sodium is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Cromolyn Sodium interact with any supplements?
Yes. Cromolyn Sodium has documented interactions with 17 supplements in our database — Umckaloabo is not one of them. The Cromolyn Sodium interaction page linked on this page lists every one, ranked by severity.
