Prolotherapy and Eribulin Mesylate

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 Eribulin Mesylate 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 Eribulin Mesylate, 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 to actually watch for

What Eribulin Mesylate’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 Eribulin Mesylate’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. 4 of them are worth acting on rather than waiting out — marked below.

  • A low white blood cell count Worth acting on mentioned in 28.9% of FDA reports for Eribulin Mesylate
  • Low potassium Worth acting on
  • An irregular heartbeat Worth acting on
  • Anemia Worth acting on
  • Fever mentioned in 14.7% of FDA reports for Eribulin Mesylate
  • Numbness or tingling mentioned in 5.8% of FDA reports for Eribulin Mesylate
  • Hair loss
  • Constipation
  • Stomach pain
  • Tiredness

Showing the 10 most notable of 12 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 Eribulin Mesylate. Read the label on DailyMed › Where a percentage is shown, it is the share of 3,719 voluntary FDA FAERS reports for Eribulin Mesylate 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.

From our pharmacist’s overview on the Eribulin Mesylate page

“Eribulin mesylate (Halaven) is an infused chemotherapy, used most often for advanced breast cancer, and one of its known effects is stretching the heart's QT interval, the recovery pause between beats on an ECG. All 13 supplements on this page can do the same thing, so pairing any of them with eribulin stacks that strain and raises the…”

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 20, 2026. The Prolotherapy and Eribulin Mesylate 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 Eribulin Injection

What Is Eribulin Injection Used For?

Brand name: Halaven

Eribulin mesylate injection (brand name Halaven) is used to treat metastatic breast cancer in patients who have already received at least two prior chemotherapy regimens for metastatic disease, including an anthracycline and a taxane. It is also approved for unresectable or metastatic liposarcoma in patients who have received a prior anthracycline-containing regimen.

Both uses are for advanced cancers that have already been treated with other therapies. This is not a first-line treatment — it is used when the cancer has progressed despite earlier chemotherapy.

Most-Reported Side Effects for Eribulin Mesylate

From FAERS, the FDA’s public side-effect reporting system (3,719 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Neutropenia 537 reports
Malignant neoplasm progression 382 reports
Febrile neutropenia 331 reports
Myelosuppression 310 reports
Fever 215 reports
