The bottom line No known interaction

We found no known interaction between Prolotherapy 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.

Prolotherapy 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 Prolotherapy in our sources. This does not guarantee that the combination is completely free of risk — research on Prolotherapy alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Prolotherapy 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.

Prolotherapy is a treatment rather than something you take. Tell whoever provides it which medicines you use, and ask your prescriber whether it is appropriate for your health and treatment. 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.

Prolotherapy safety at a glance

Prolotherapy overall Use caution Generally considered low-risk when performed by a trained clinician, but it is an invasive injection with possible side effects.
Pregnancy Avoid Not recommended during pregnancy due to lack of safety data and the use of injections and anesthetics.
Breastfeeding Use caution Safety has not been well studied; discuss with your doctor before considering it.

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

What Azithromycin’s Own FDA Label Lists

This is not an interaction — none of it involves Prolotherapy. These are the most notable effects listed in the ADVERSE REACTIONS section of Azithromycin’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 have Prolotherapy and take the medicine. 10 of them are worth acting on rather than waiting out — marked below.

  • Hearing loss Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Fainting Worth acting on
  • An irregular heartbeat 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
  • Kidney problems Worth acting on

Showing the 10 most notable of 45 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 Azithromycin. Read the label on DailyMed › 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. Prolotherapy’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Prolotherapy side to compare — that is a limit of the record, not a statement that Prolotherapy has no side effects.

Everything else you take

See Every Supplement That Interacts With Azithromycin

This page covers Prolotherapy only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Azithromycin page lists 92 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), Arsenic (major), Cesium (major) and Ephedra (major).

By severity: 8 major · 71 moderate · 13 minor.

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.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Prolotherapy is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Prolotherapy reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Prolotherapy and Azithromycin records this page draws on were last updated June 20, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Prolotherapy

What is Prolotherapy?

  • Chronic low back pain
  • Knee osteoarthritis
  • Tendon and ligament pain
  • Joint instability
  • Tennis elbow and other tendinopathies

Prolotherapy is not a dietary supplement or herb; it is an injection procedure in which an irritant solution (usually dextrose) is injected near painful joints, tendons, or ligaments to encourage a healing response. The evidence is mixed and generally low-to-moderate quality, with some studies showing modest pain relief for conditions like knee osteoarthritis and chronic low back pain. It should only be done by a trained, licensed clinician, so talk with your doctor before considering it.

Not applicable (a medical injection procedure) · Injected solution, most often dextrose (sugar water) mixed with a local anesthetic

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

Prolotherapy: dosing

There is no single standard dose or protocol for prolotherapy. The type of solution (most often dextrose), the concentration, the amount injected, the number of injection sites, and how many sessions are needed all vary based on the clinician, the body area, and the condition being treated.Treatment is usually given as a series of sessions spaced a few weeks apart.

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
Pneumonia 3,225 reports
Cough 3,120 reports
Drug hypersensitivity 2,991 reports
