Filler Complications: Reading the FDA Reports, Not Just Counting Them

Reviewed for medical accuracy against our Medical Review Board  ·  Last updated 23 August 2026

The FDA holds a public database of adverse events reported for medical devices, and fillers are devices. It contains 9,792 reports for Juvederm alone. We pulled the figures and then did the part nobody does: read the reports. That matters, because filtering for deaths returns eight results and reading them shows they do not support the claim that number implies. One of the eight involved a substance that was not Juvederm at all.

What follows is the real picture: which complications are genuinely documented, which counts fall apart on inspection, and the warning signs that are worth memorising.

1. Read this before any number

Everything below comes from MAUDE, the FDA's device adverse event database. It is genuinely useful and it is easy to misuse, so here is what it is not:

Used properly, this data tells you which kinds of things go wrong and what the warning signs are. It cannot tell you your odds.

2. Why counting is not enough: the death reports

Filter the Juvederm reports by event type "Death" and you get eight results. That number, published on its own, would be alarming and wrong. We read all eight. Here is what they actually contain:

So the count is eight and the evidence supports none of them as a filler-caused death. That is not us defending the industry, it is what the reports say when you open them.

We are including this because it is the most useful thing on the page. Somebody will find that count and publish "8 deaths linked to Juvederm", and now you know what sits behind it. It is also the reason to treat every other number here as a starting point for reading rather than a conclusion.

3. Vascular occlusion, the one that matters most

This is the complication that justifies the whole subject being taken seriously, and unlike the death counts the data here is coherent and consistent with a recognised mechanism. Filler enters or compresses a blood vessel and the tissue downstream loses its blood supply.

Vascular problem codes across the Juvederm reports
Coded problemReports
Obstruction or occlusion695
Vascular system, circulation impaired322
Necrosis261

Necrosis means tissue death. 261 reports describe it. The other filler brands show the same signature at smaller volumes: Radiesse has obstruction or occlusion as its second most reported problem at 267 of 1,641 reports, and Belotero shows necrosis in 37 of 321.

The reason this is survivable is that for a hyaluronic acid filler there is an antidote. Hyaluronidase breaks the gel down, and given promptly it can restore circulation. That is the single strongest argument for choosing a dissolvable product, covered in our filler guide.

4. Vision loss, and the case that recovered

Filler reaching an artery connected to the eye can cause blindness. This is the most feared complication and the data on it holds up:

Vision-related problem codes, Juvederm reports
Coded problemReports
Blurred vision53
Visual impairment46
Visual disturbances40
Loss of vision34

Unlike the death reports, these are internally consistent. The loss of vision reports are repeatedly co-coded with obstruction or occlusion and with impaired circulation, which is exactly the mechanism you would expect. They describe a recognised event rather than an unexplained one.

Two of them cite a peer-reviewed case report, and it is worth knowing about because of what it documents: Danks, Dalgliesh and Ayton, "Cosmetic Filler Blindness: Recovery After Repeated Hyaluronidase Injections", Aesthetic Surgery Journal, 2021. Recovery. Vision loss from filler is not automatically permanent if the response is fast and hyaluronidase is available.

Which turns an abstract fear into a practical checklist. Any vision change after filler is an emergency, the treatment exists, and whether your clinic has it on site is a question you can ask before anything is injected.

5. Nodules and granulomas

Less dangerous, far more common, and the reason many people end up unhappy rather than harmed.

Lump-related problem codes, Juvederm reports
Coded problemReports
Nodule1,099
Subcutaneous nodule306
Granuloma272
Abscess646
Unspecified infection1,199

Worth separating two different things. A lump in the first few weeks is extremely common and usually just tissue settling: the FDA trial data on our filler recovery page found 81.1% of patients reported lumps or bumps, with 15.8% of those lasting beyond thirty days. A firm nodule appearing months later is a different event, sometimes triggered by an illness or vaccination, and is what the granuloma code describes.

The infection and abscess counts are a reminder that this is a sterile procedure being performed on skin, and that where it is performed matters.

6. The reports that blame the technique

MAUDE codes a device problem as well as a patient problem, and this is where it gets uncomfortable for the industry:

Device problem codes, Juvederm reports
Coded device problemReports
Adverse event without identified device or use problem6,968
Improper or incorrect procedure or method952
Gel leak272
Off-label use304
Migration or expulsion of device102
Migration46
Device remains implanted61

952 reports coded as improper or incorrect procedure or method. That is technique, not product. And 304 coded as off-label use, meaning the filler was placed somewhere its approval does not cover.

Set against 6,968 reports where no device or use problem was identified at all, the proportion is modest. But it is the clearest available evidence for something this site says constantly: who injects you matters more than which brand they use. Checking a licence is free and takes two minutes, and our guide to verifying one walks through it.

7. Patterns by product

Report totals track how much a product is used, so the totals themselves say little. What is informative is the shape of each product's reports, which tracks what the material is:

Total reports and the most reported problem for each product
ProductReports Signature problem
Juvederm9,792Oedema, skin irritation, inflammation
Versa2,461Largely no known impact, then pain
Sculptra2,009Granuloma, 258
Radiesse1,641Obstruction or occlusion, 267
Restylane1,217Swelling, pain, erythema
RHA588Foreign body embolism, 183
Belotero321Necrosis, 37
Revanesse209Swelling, nodule
Bellafill148Pain, swelling

Sculptra works by provoking a collagen response, and granuloma is its second most reported problem. Radiesse is a firm particulate gel and shows vascular obstruction prominently. RHA's single largest reported problem is foreign body embolism, 183 of 588 reports. Those are coherent with the materials, which is why they are worth raising when choosing a product for a particular area rather than treating all fillers as interchangeable.

8. The warning signs

Learn these. They are the practical output of everything above:

These can begin during the injection or hours afterwards. They are a same-day emergency, not a wait-and-see. For hyaluronic acid filler the treatment is hyaluronidase, and the published case above shows that even vision loss has recovered when it was given promptly and repeatedly.

9. Three questions before you book

  1. "Is this product hyaluronic acid?" If yes, it can be dissolved. Radiesse, Sculptra and Bellafill cannot.
  2. "Do you keep hyaluronidase on site?" Not "can you get it". On site.
  3. "What is your protocol if you suspect a vascular occlusion?" A good injector answers this immediately and without irritation.

Add a fourth if you are being treated in the nose, the temple or under the eye, which are the highest risk vascular territories: ask how often they treat that specific area.

10. Keeping this in proportion

A page that lists 261 necrosis reports and 34 vision losses needs an honest closing note, because the impression it leaves should be accurate rather than merely cautious.

Those reports accumulated across many years and many millions of syringes, and MAUDE has no denominator so no rate can be calculated from them. The overwhelming majority of the 9,792 Juvederm reports describe swelling, irritation, inflammation and lumps. The serious vascular events are a small minority of a database that itself captures a small and unknown fraction of treatments.

Fillers are, on the available evidence, a reasonably safe procedure performed badly quite often and catastrophically rarely. The honest summary is that the risk is concentrated in who injects you, where they place it, and whether they can reverse it. All three are things you can influence before anything happens, which is more than can be said for most medical risks.

Our dermal filler guide covers the products and the dissolvability split, filler recovery covers what normal looks like from FDA trial diaries, and our city guides cover the clinics we have researched.

Most of these figures are Juvederm’s. It has 9,792 reports, more than any other filler, almost certainly because it is the most used. The Juvederm guide splits them by product.

Frequently asked questions

Has anyone died from dermal filler?
The FDA device database returns eight death-coded reports for Juvederm, and reading them is essential because they do not support that number. One states the event was deemed not device related. One describes a doctor injecting unknown substances from an unidentified jar while calling it Juvederm, so the product was not identified as Juvederm at all. One involved a death during sleep where investigation with the coroner found another explanation. Two are duplicates with no detail, one came from an anonymous caller, and one is a bare administrative response. The count is eight; the evidence supports none as a filler-caused death.
Can filler cause blindness?
Yes, and this is the most serious documented risk. The FDA database holds 34 reports coded loss of vision for Juvederm, plus 53 blurred vision, 46 visual impairment and 40 visual disturbances. Unlike the death reports, these hold up on inspection: they are repeatedly co-coded with vascular obstruction and impaired circulation, which is the recognised mechanism. Importantly, a peer-reviewed case report cited in two of them documents recovery of vision after prompt repeated hyaluronidase injections, so it is not automatically permanent.
What is the most common filler complication?
By report volume, the unremarkable ones. Across 9,792 Juvederm reports the leading codes are oedema at 1,729, skin irritation at 1,725, inflammation at 1,450, unspecified infection at 1,199 and nodule at 1,099 plus a further 306 subcutaneous nodules. The serious vascular events are a small minority: 695 obstruction or occlusion, 322 impaired circulation and 261 necrosis.
What is vascular occlusion?
Filler entering or compressing a blood vessel so the tissue downstream loses its blood supply. It is the complication that makes fillers genuinely risky rather than merely inconvenient, and it appears 695 times in the Juvederm reports, with necrosis, meaning tissue death, appearing 261 times. Radiesse shows the same signature, with obstruction or occlusion its second most reported problem. For hyaluronic acid filler the treatment is hyaluronidase, which is why choosing a dissolvable product and a clinic that stocks the enzyme matters.
Do fillers ruin your face?
The data does not support that framing, but it does support a narrower concern. The reports are dominated by swelling, irritation and lumps that resolve. What is worth taking seriously is that 952 reports are coded as improper or incorrect procedure or method and 304 as off-label use, meaning the product was placed somewhere its approval does not cover. Those are technique problems rather than product problems, which is the argument for choosing your injector carefully rather than avoiding fillers.
Which filler has the most complications?
This is the question the data cannot answer, and anyone answering it with report counts is misusing them. There is no denominator: Juvederm leads with 9,792 reports almost certainly because it is the most used filler in the country. What the data shows instead is a coherent pattern within each product: granuloma is prominent for Sculptra at 258 of 2,009 reports, vascular obstruction for Radiesse at 267 of 1,641, and foreign body embolism for RHA at 183 of 588.
What are the warning signs after filler?
Severe or escalating pain out of proportion to the procedure, blanching or white patches, mottled or dusky skin in a pattern, any change in vision, skin cold to the touch, and anything worsening rather than improving after day three. These can begin during the injection or hours later, and they are a same-day emergency rather than a wait-and-see. For hyaluronic acid filler the treatment is hyaluronidase.
Are filler lumps a complication or normal?
Both, depending on timing. Lumps in the first weeks are the normal outcome: FDA trial diary data found 81.1% of patients reported lumps or bumps, and 15.8% of those lasted beyond thirty days. A firm nodule appearing months later is a different event, sometimes triggered by an illness or vaccination, and appears in the FDA reports as granuloma 272 times and nodule 1,099 times. A lump at month four warrants a call; a lump at week two usually does not.
Can filler migrate?
The FDA device data codes migration or expulsion of device 102 times among the Juvederm reports, plus 46 coded simply as migration and 272 as gel leak. Overplacement, injecting too superficially and retreating before previous product has resolved are the usual explanations. Because hyaluronic acid can be dissolved, it is a recoverable problem rather than a permanent one, which is a practical argument for HA over the non-dissolvable materials.
Should I be worried about getting filler?
Proportionately. These reports accumulated over many years and many millions of syringes, and MAUDE has no denominator so no rate can be calculated from them. The overwhelming majority describe swelling, irritation and lumps. The realistic summary is that fillers are performed badly reasonably often and catastrophically rarely, and that the risk concentrates in who injects you, where they place it and whether they can reverse it. All three are things you can influence beforehand.
Where does this data come from?
MAUDE, the FDA's Manufacturer and User Facility Device Experience database, queried through the openFDA device event endpoint. Fillers are regulated as medical devices rather than drugs, so this is where their adverse events are reported, in place of the prescribing information a drug would have. It is public. It is also passive voluntary surveillance, so the counts are reports rather than rates, reporting is incomplete, and a report does not establish that the product caused the event.
Is hyaluronidase always available?
No, and that is precisely why it is worth asking. It is the enzyme that dissolves hyaluronic acid filler and it is the treatment for a suspected vascular occlusion, where minutes matter. Ask whether the clinic keeps it on site rather than whether they can obtain it. If the product being used is Radiesse, Sculptra or Bellafill, hyaluronidase will not dissolve it, which is a reason to prefer a hyaluronic acid filler for a first treatment.
