Prolotherapy and Fenoprofen Calcium

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 Fenoprofen Calcium 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 Fenoprofen Calcium, 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 Fenoprofen Calcium’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 Fenoprofen Calcium’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.

  • Bleeding in the gut Worth acting on
  • High potassium Worth acting on
  • Heart failure Worth acting on
  • Confusion Worth acting on
  • Kidney problems Worth acting on
  • Raised blood pressure Worth acting on
  • Shortness of breath Worth acting on
  • Liver problems Worth acting on
  • Bleeding or bruising Worth acting on
  • A higher chance of infection Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Fenoprofen Calcium. Read the label on DailyMed › 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.

Overlapping uses

What Fenoprofen Calcium Is Prescribed For, and What Prolotherapy Has Been Studied For

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

Fenoprofen Calcium is prescribed for: Fenoprofen is used to relieve mild to moderate pain in adults. It is also used to reduce the pain, swelling, and stiffness caused by rheumatoid arthritis and osteoarthritis. These uses are supported by products including Fenoprofen Calcium, Fenopron, and Nalfon capsules. Nalfon is also available as a tablet.

Prolotherapy has been studied for:

  • Osteoarthritis studied, not established Prolotherapy has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Prolotherapy for osteoarthritis

    The results of two double-blind human trials suggest that prolotherapy may effectively treat osteoarthritis.

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 Fenoprofen Calcium on your own; if you are taking Prolotherapy 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 Fenoprofen Calcium

From our pharmacist’s overview on the Fenoprofen Calcium page

“The kidneys and the stomach lining take the brunt of any NSAID, and fenoprofen calcium (Nalfon), prescribed for arthritis and other pain, is no exception. This list of 32 interacting supplements deserves real caution; five carry a major rating, and understanding those five comes first.”

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 Fenoprofen Calcium 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.
