The US Food and Drug Administration (FDA) has warned against buying or using Ort-Flx and RX7 Articulaciones after laboratory testing found medicines missing from their labels. Both contain the steroid dexamethasone and the anti-inflammatory medicine diclofenac. Ort-Flx also contains the muscle relaxant methocarbamol.
The notices, dated 28 October 2026, concern products marketed for pain relief. They matter to people with diabetes because dexamethasone can raise blood sugar. However, the most important message for anyone already taking either product is about stopping safely.
Already taking Ort-Flx or RX7 Articulaciones? Contact a healthcare professional immediately for help to discontinue it safely. The FDA specifically says a professional should assess the risk of corticosteroid withdrawal. Do not try to calculate a taper from the product label or this article.
Which products are involved?
The FDA describes Ort-Flx as a product promoted for pain, arthritis and allergies, and RX7 Articulaciones as a product promoted for joint and muscle pain. The products were sold through websites including eBay and may also have been available in shops.
- Ort-Flx: undeclared diclofenac, dexamethasone and methocarbamol.
- RX7 Articulaciones: undeclared diclofenac and dexamethasone.
The Ort-Flx warning and RX7 Articulaciones warning contain actual product photographs. Use those notices, rather than our generic illustration, when checking a pack. These are FDA public safety notifications, not evidence that the products are approved medicines.
Why a hidden steroid changes the safety advice
Dexamethasone is a corticosteroid used under medical supervision for several conditions. A prescribed medicine has instructions and a known intended dose. An undeclared ingredient means someone may be exposed without knowing they are taking it.
The NHS warns that suddenly stopping dexamethasone, especially after substantial or prolonged exposure, can cause withdrawal problems. A clinician may need to reduce a prescribed steroid gradually. That is background information, not a tapering plan for an unlabelled product.
Keep the packaging and tell the clinician how long you have used the product, how often you have taken it and when you last took it. Include other supplements and medicines in the discussion. If your usual service is unavailable, use an urgent medical advice service rather than waiting for a routine appointment. In the UK, NHS 111 can help direct urgent care.
Do not start, stop or alter a prescribed steroid or another prescribed medicine on the strength of this warning. The warning concerns these specific products; a clinician needs to assess your treatment separately.
What this means for blood sugar
Steroid medicines can affect glucose control. The NHS notes that someone with diabetes may need professional treatment adjustments while taking dexamethasone and again after stopping it. The presence of a hidden steroid is therefore worth mentioning when seeking help for unexpected high readings.
Follow your existing glucose-monitoring and sick-day plan. Do not skip or change insulin or other diabetes medicine doses unless your care team advises you. A reading alone cannot show which ingredient caused a change, and this warning does not mean everyone who used either product will develop a complication.
Get emergency help if you suspect high blood sugar and have vomiting, stomach pain, rapid breathing, marked drowsiness, confusion, fruity-smelling breath or high ketones. These can signal serious illness. Do not wait for the supplement review or a routine diabetes appointment. Call the local emergency number; in the UK, call 999 or go to A&E, and in the US call 911. Do not drive yourself.
The other hidden medicines matter too
Diclofenac belongs to the non-steroidal anti-inflammatory drug (NSAID) group. The FDA highlights risks including heart attack, stroke and serious stomach or intestinal bleeding. Taking other NSAID-containing products can increase the risk of serious side effects.
For this reason, ask a pharmacist or prescriber to review the full medicine list, including non-prescription painkillers. Do not add another pain medicine to compensate for stopping a suspect product without checking what is suitable for you.
Methocarbamol, found in Ort-Flx, can cause sleepiness, dizziness and low blood pressure. The FDA warns that these effects can make driving or operating machinery unsafe.
Seek emergency help for vomiting blood, new chest pain or stroke symptoms such as sudden one-sided weakness or difficulty speaking. Severe breathing difficulty or collapse also needs emergency assessment. Black stools, severe stomach pain, pronounced weakness or vomiting need urgent medical advice; if symptoms are severe or you cannot stay awake, seek emergency help. Take the product packaging and medicine list if possible, without delaying care.
What the warning can and cannot tell us
The FDA has confirmed hidden ingredients in the products it tested. The notices do not provide a clinical trial, a numerical chance of harm for each user or a personal exposure assessment. Feeling well does not make an undeclared medicine an acceptable ingredient, but finding the name on your pack does not establish that a particular symptom was caused by it.
Suspected side effects can be reported through the FDA MedWatch programme. Reporting does not replace medical care. For further patient-facing information, see our type 2 diabetes guide and latest diabetes and medicine-safety news.
