Class II U.S. Food and Drug Administration

Baxter Healthcare Corporation Brand Name: Welch Allyn recall: Display screen may unintentionally flicker due to a software issue. Exposure

Recall published 7 months ago

Display screen may unintentionally flicker due to a software issue. Exposure to flickering lights may induce photosensitive seizure activity in susceptible individuals.

The hazard: Device malfunction

This is a device recall, and in FDA language that usually means a correction rather than a removal: the device stays in use and the manufacturer fixes, patches or re-instructs.

What the notice says: Display screen may unintentionally flicker due to a software issue. Exposure to flickering lights may induce photosensitive seizure activity in susceptible individuals.

Why it matters: The device may not perform as intended — a mechanical failure, a software defect, an inaccurate reading, or an alarm that does not sound. For a device someone depends on, the consequence of the failure is usually worse than the failure itself.

Symptoms and when to call a doctor

If the device supports a vital function, do not disable or remove it on your own judgement. Contact the clinician who prescribed or fitted it, and use the back-up arrangement they gave you. Go to an emergency department if the symptoms the device is meant to manage are getting worse, or if an implanted device gives an unexpected alarm or shock.

This page is general information, not medical advice. If you feel unwell, a clinician who can see you is the only person able to judge your case.

What to do about Malfunction

Baxter Healthcare Corporation — This is a device recall, and in FDA language that usually means a correction rather than a removal: the device stays in use and the manufacturer fixes, patches or re-instructs.

  1. Match the model, catalogue, lot and serial numbers on your device against the identifiers listed on this page.
  2. If you are a clinic or facility, quarantine affected stock and record the correction in your recall log.
  3. Report device problems to the FDA through MedWatch — that database is where this recall came from.
  4. If the device is implanted, or you depend on it daily, speak to your clinician before changing anything about how you use it.

Replacements, repairs and reimbursement

Device remedies run through the supply chain, so the route depends on who sold you the unit.

  • Contact the distributor or clinic named on your paperwork and quote the recall number on this page. They will tell you whether the remedy is a repair, a replacement or an instruction update.
  • If the device was billed to insurance or Medicare, the replacement is usually billed the same way; you should not face a second deductible for a recall.
  • Keep every piece of correspondence. If a recalled device caused harm, that paper trail is what a claim rests on.
  • Consumer-purchased devices such as monitors and test kits are normally replaced free, with return shipping paid.
