Drug & supplement interaction

Androstenedione + Aztreonam

Aztreonam brand name: Azactam.

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 Androstenedione and Aztreonam 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.

Androstenedione 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 Androstenedione 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.

How we checked

Why No Interaction Is Listed for Aztreonam

Interactions in our licensed database are recorded against drug classes, not just single drug names. Aztreonam is filed under a single classification — antibiotic drugs. Androstenedione has documented interactions with 1 drug class — the most serious being estrogens (moderate) — and none of Aztreonam’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 Androstenedione and Aztreonam 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.

    Aztreonam

    Listed in the ADVERSE REACTIONS section of the FDA label for Aztreonam. Read the label on DailyMed ›

Reported for Androstenedione but not commonly for Aztreonam: low mood, a change in sex drive, erection problems and acne.

Effects for Aztreonam come from the ADVERSE REACTIONS section of its FDA label; effects for Androstenedione come from the Natural Medicines adverse-effect record, quoted above. 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. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

See Every Supplement That Interacts With Aztreonam

This page covers Androstenedione 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 Androstenedione

What is Androstenedione?

Androstenedione
  • Muscle building
  • Athletic performance
  • Boosting testosterone
  • Anti-aging
  • Increasing libido

Androstenedione is a prohormone that the body can convert into testosterone and estrogen, but studies have not shown that taking it reliably builds muscle or improves athletic performance. It carries real risks, is a controlled substance in the United States, and is banned in nearly all sports, so most people should avoid it.

Not a plant; a hormone precursor made synthetically or in the body · Capsules, tablets, sublingual sprays, powders (where legally available)

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

Androstenedione: dosing

There is no established safe or effective dose for androstenedione. Past products varied widely, and because it is now a controlled substance, it is not appropriate to recommend any amount.If you encounter a product containing it, do not assume the label dose is safe or accurate. The safest choice is to avoid it.

About Aztreonam Injection

What Is Aztreonam Injection Used For?

Brand name: Azactam

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.

Most-Reported Side Effects for Aztreonam

From FAERS, the FDA’s public side-effect reporting system (7,148 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Infective pulmonary exacerbation of cystic fibrosis 849 reports
Dyspnea 440 reports

Taking Androstenedione and Aztreonam Together: Common Questions

Is it safe to take Androstenedione with Aztreonam?
We do not list a known interaction between Androstenedione and Aztreonam. 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 Androstenedione and Aztreonam 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.
How was the Androstenedione and Aztreonam combination checked?
Interactions in our licensed database are recorded against drug classes. Aztreonam is filed under 1 classification, and Androstenedione has documented interactions with 1 drug class — none of Aztreonam'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 Androstenedione interact with any other medications?
Yes. Androstenedione has 41 documented drug interactions in our database — Aztreonam 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 Aztreonam interact with any supplements?
Yes. Aztreonam has documented interactions with 27 supplements in our database — Androstenedione is not one of them. The Aztreonam interaction page linked on this page lists every one, ranked by severity.
