Tolu Balsam and Aztreonam

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 Aztreonam and Tolu Balsam 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 Tolu Balsam at all — not against Aztreonam, 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.

Tolu Balsam safety at a glance

Tolu Balsam overall Use caution Generally used in small amounts in foods and cough products, but it can cause allergic reactions and lacks strong safety data.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety during breastfeeding is unknown, so avoid medicinal use.

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

What Aztreonam’s Own FDA Label Lists

This is not an interaction — none of it involves Tolu Balsam. These are the most notable effects listed in the ADVERSE REACTIONS section of Aztreonam’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.

  • Bleeding in the gut Worth acting on
  • Blood clots Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Wheezing Worth acting on
  • Shortness of breath Worth acting on mentioned in 6.2% of FDA reports for Aztreonam
  • Confusion Worth acting on
  • A severe skin reaction Worth acting on
  • Seizures Worth acting on
  • Chest pain Worth acting on
  • A low platelet count Worth acting on

Showing the 10 most notable of 37 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Aztreonam. Read the label on DailyMed › Where a percentage is shown, it is the share of 7,148 voluntary FDA FAERS reports for Aztreonam that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Tolu Balsam’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Tolu Balsam side to compare — that is a limit of the record, not a statement that Tolu Balsam has no side effects.

Overlapping uses

What Aztreonam Is Prescribed For, and What Tolu Balsam Has Been Studied For

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

Aztreonam is prescribed for: Azactam (aztreonam for injection) is used to treat infections caused by susceptible gram-negative bacteria. It is approved for urinary tract infections (including kidney infections and bladder infections), lower respiratory tract infections (including pneumonia), bloodstream infections (septicemia), skin and skin-structure infections (including those related to wounds, ulcers, and burns), intra-abdominal infections (including peritonitis), and gynecologic infections (including endometritis and pelvic cellulitis). Azactam is also used alongside surgery to manage infections such as abscesses and infections involving perforated organs. In seriously ill patients who may also have gram-positive bacterial infections, it is often started together with another antibiotic that covers those bacteria.

When anaerobic bacteria (bacteria that don't need oxygen) are also suspected, an anti-anaerobic antibiotic is added as well.

Tolu Balsam has been studied for:

  • Respiratory tract infections studied, not established Tolu Balsam has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Tolu Balsam for respiratory tract infections

    Although there has been interest in using oral and inhaled Tolu balsam for respiratory tract infections, including bronchitis, laryngitis, and croup, there is insufficient reliable information about the clinical effects of Tolu balsam for this purpose.

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 Aztreonam on your own; if you are taking Tolu Balsam for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Aztreonam

This page covers Tolu Balsam only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Aztreonam page lists 27 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Bacillus Coagulans (moderate), Bacillus Subtilis (moderate), Bifidobacterium Animalis Subsp. Lactis (moderate), Bifidobacterium Bifidum (moderate) and Bifidobacterium Breve (moderate).

By severity: 26 moderate · 1 minor.

From our pharmacist’s overview on the Aztreonam page

“Every entry on this page tells one story, and it is a gentler one than most interaction lists. Aztreonam (Azactam) is an injectable or inhaled antibiotic used for serious infections, often in people with cystic fibrosis, and none of these 27 supplement pairings makes the drug itself riskier or weaker.”

About Tolu Balsam

What is Tolu Balsam?

  • Cough and sore throat
  • Chest congestion
  • Wound and skin care (topical)
  • Flavoring and fragrance
  • Mild expectorant

Tolu balsam is a fragrant resin from a South American tree that has long been used as a flavoring and as an ingredient in cough syrups and throat lozenges. Good-quality human studies are lacking, so its real effectiveness is uncertain, and it can cause allergic skin reactions in some people. Talk to a pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have allergies.

Myroxylon balsamum · Fabaceae · Resinous balsam (oleoresin) collected from the tree trunk · Syrups, cough lozenges, throat preparations, tinctures, and as a flavoring or fragrance ingredient

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

Tolu Balsam: dosing

There is no well-established standardized dose for tolu balsam. It is most often found as a minor ingredient in cough syrups, lozenges, and tinctures rather than taken on its own.If you use a product that contains tolu balsam, follow the directions on the label and do not exceed the recommended amount.
