Drug & supplement interaction

Indium + Azithromycin

Azithromycin brand names: Zithromax, Zmax, Azasite.

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 Indium and Azithromycin 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.

Indium and Azithromycin

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 Azithromycin and Indium 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 Indium at all — not against Azithromycin, 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.

What to actually watch for

No Interaction Found — But Data Suggests Indium and Azithromycin 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. One of them is worth acting on rather than waiting out — marked below.

  • Chest pain Worth acting on Additional detail

    Indium

    “Occupational exposure to indium by inhalation can lead to potentially fatal interstitial lung disease, characterized by pulmonary alveolar proteinosis, progressing to fibrosis with or without emphysema. The disease develops slowly with shortness of breath, chest tightness and pain, dry cough, dyspnea, and deteriorating pulmonary function tests.”

Reported for Indium but not commonly for Azithromycin: shortness of breath.

Effects for Azithromycin come from the ADVERSE REACTIONS section of its FDA label; effects for Indium come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 59,712 voluntary FDA FAERS reports for Azithromycin 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.

From our pharmacist’s overview on the Azithromycin page

“A five-day Z-Pak for a sinus or chest infection seems too brief to fuss over, but azithromycin (Zithromax, Zmax) deserves genuine caution around supplements, and the eight major-rated entries on this list are the ones to understand first. Most of those involve the heart.”

About Indium

What is Indium?

  • Anti-aging
  • Boosting energy
  • Supporting hormone or gland function
  • General 'wellness' or trace mineral supplementation

Indium is a metallic chemical element sometimes sold as a liquid 'trace mineral' supplement with bold anti-aging and energy claims, but it is not a recognized essential nutrient and there is no reliable human evidence that it offers any health benefit. Because safety data are very limited and it is a heavy metal, most people should avoid it and talk with a pharmacist or doctor first.

Not a plant; a chemical element (indium) sold as a mineral supplement · Liquid 'indium sulfate' drops, sometimes capsules

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

Indium: dosing

There is no established or recommended dose for indium, because it is not an essential nutrient and has no proven benefit. Products that contain it are not standardized, and label amounts vary.We do not recommend a specific dose. In general, the safest choice is to avoid it.

About Azithromycin

What Is Azithromycin Used For?

Brand names: Zithromax, Zmax, Azasite

  • Azithromycin is used to treat certain bacterial infections, such as bronchitis; pneumonia; sexually transmitted diseases (STD); and infections of the ears, lungs, sinuses, skin, throat, and reproductive organs. Azithromycin also is used to treat or prevent disseminated Mycobacterium avium complex (MAC) infection [a type of lung infection that often affects people with human immunodeficiency virus (HIV)]. Azithromycin is in a class of medications called macrolide antibiotics. It works by stopping the growth of bacteria.

  • Antibiotics such as azithromycin will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

Most-Reported Side Effects for Azithromycin

From FAERS, the FDA’s public side-effect reporting system (59,712 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Dyspnea 4,651 reports
Nausea 3,461 reports

Taking Indium and Azithromycin Together: Common Questions

Is it safe to take Indium with Azithromycin?
We do not list a known interaction between Indium and Azithromycin. 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 Indium and Azithromycin have any of the same side effects?
Yes — our sources link each of them separately to 2 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.
Does Azithromycin interact with any supplements?
Yes. Azithromycin has documented interactions with 92 supplements in our database — Indium is not one of them. The Azithromycin interaction page linked on this page lists every one, ranked by severity.
