Reporting a Bad Product to FDA MedWatch

By Alsen Walker · Editorially reviewed on 25 August 2026 · Not medically reviewed by a clinician

MedWatch is the FDA programme for reporting problems with medicines, including side effects, suspected counterfeits, and quality defects. Anyone can file a report. It takes a few minutes, it does not require certainty about what happened, and it is how patterns in unapproved and falsified products get identified.

What is worth reporting

Serious side effects, including anything requiring medical attention or hospital treatment.

Suspected counterfeit or falsified product.

Quality problems: a product that looks wrong, packaging that seems altered, a device that does not work as it should.

Problems with compounded preparations, including suspected dosing errors from unclear concentration labelling.

You do not need to prove the product caused what happened. Suspicion is the threshold, and that is deliberate.

What to gather first

The product name and, if you have it, the manufacturer or compounding pharmacy.

Lot or batch number and expiry date, from the packaging.

Where you obtained it.

The dose you took and when.

What happened, with dates, and what treatment you received.

Your other medications and relevant medical history.

Keep the product and packaging. Do not discard them, since they may be requested.

How to file

FDA provides an online consumer reporting form through MedWatch, which is the most straightforward route for patients. Postal and telephone options also exist.

Your clinician or pharmacist can file on your behalf, and a report from a clinician carries clinical detail yours may not. Both can be filed; duplication is not a problem.

Manufacturers have their own reporting lines and are themselves obliged to report to FDA.

Where else to report

State board of pharmacy, for problems with a pharmacy or a compounded preparation.

State medical board, for concerns about prescribing.

State attorney general, for consumer issues such as subscriptions that cannot be cancelled or misleading claims.

These are separate systems and a report to one does not reach the others. If more than one applies, file more than once.

If you bought outside the regulated supply chain

Report it anyway. People hesitate because they think they will be in trouble, and that hesitation is what allows sellers to keep operating.

The purpose is identifying dangerous products and the operations distributing them.

What happens next

Reports feed a surveillance database that FDA analyses for patterns. A single report rarely triggers action on its own; a cluster does.

You may not hear anything back, and that is normal rather than a sign it was ignored. Several current warnings on approved products originated in exactly this process.

Frequently asked questions

Do I need proof?
No. Suspicion is enough, and that is intentional.

Can I report a compounded product?
Yes, and also report it to your state board of pharmacy.

Will I get in trouble for reporting something bought online?
The purpose is identifying dangerous products. Report it.

Should my doctor report instead?
Either or both. Clinician reports add detail; duplication is fine.

Do I keep the product?
Yes. Keep the product and packaging.

Will I hear back?
Often not. Reports contribute to pattern detection rather than individual responses.
