Questions about this case?
AI Legal Assistant · free · answers in seconds · general information, not legal advice
Short answer: as of October 2026 there is no open Mirena IUD settlement, no claim form and no deadline. The two big injury cases — uterine perforation and intracranial hypertension — ended years ago, mostly in Bayer’s favor. The one case still on file is a 2024 class action in California that alleges Mirena raises breast cancer risk. We found no class certification or settlement in any source we checked, but could not confirm the current docket.

What the Mirena Lawsuits Alleged
Mirena is Bayer’s hormonal IUD; it releases levonorgestrel. Three waves of litigation have used the name:
Perforation and migration. Thousands of women alleged the device moved out of place or pierced the uterus and that Bayer under-warned about it.
Idiopathic intracranial hypertension (IIH). Plaintiffs alleged they developed IIH — also called pseudotumor cerebri, raised pressure around the brain — as a result of using Mirena.
Breast cancer. The current class action alleges that Mirena raises breast cancer risk “by a statistically significant amount of approximately 20-30%” and that Bayer failed to warn doctors and patients. Bayer called these claims “equally baseless” to an earlier, dismissed version of the same suit. These are allegations; no court has found them true.
Case Details
Breast-cancer class action (open): Copeland v. Bayer Healthcare Pharmaceuticals Inc., No. 5:24-cv-03042-BLF, U.S. District Court for the Northern District of California, San Jose Division, filed May 20, 2024. Its proposed class is women who paid an out-of-pocket cost for a Mirena IUD — it seeks money for that cost, not compensation for a cancer diagnosis. It replaced an earlier case, filed in March 2022, in which Judge Beth Labson Freeman denied most of Bayer’s motion to dismiss on October 5, 2023; that plaintiff voluntarily dismissed in May 2024.
IIH litigation (closed): federal IIH cases were centralized in the Southern District of New York before Judge Paul A. Engelmayer. After the plaintiffs’ general-causation experts were excluded, he granted summary judgment for Bayer. The Second Circuit affirmed on December 8, 2020 (No. 19-2155).
Perforation litigation (closed): a federal MDL created in 2013 in the Southern District of New York. Per the law firm Miller & Zois, about 1,300 cases were dismissed in July 2016 after the plaintiffs’ experts were rejected; the Second Circuit affirmed in 2017. Parallel New Jersey state cases were closed as well.
Status: No Mirena IUD Settlement to Claim
The Copeland breast-cancer case is the only Mirena class action we could find. We could not confirm its current docket status from the court record as of October 2026; we found no class certification, settlement or notice program in any source we checked. Drugwatch, updated in September 2026, reports “no new major developments” in Mirena litigation and says most lawyers have stopped accepting cases.
Individual injury suits can still be filed, but each stands alone, faces the same causation rulings that ended the MDLs, and is subject to state filing deadlines.
Are You Affected?
Perforation or IIH injury: the group deals are closed. If you had a case in the MDL or in New Jersey, your lawyer at the time has your file and knows whether you were paid. There is nothing new to sign up for.
Breast-cancer class action: the proposed class in Copeland is women who paid out of pocket for a Mirena IUD. We found no class certification, so no one appears to be a class member yet and we found no notice. If a class is ever certified or a settlement is reached, notice comes from a court-appointed administrator, and the case would appear on our open class action settlements list.

What the Mirena Cases Have Paid
The only public Mirena IUD settlement is the perforation deal. Per Drugwatch, Bayer offered $12.2 million in August 2017 and estimated it would cover 4,600 claims in the federal MDLs and New Jersey; the master settlement agreement followed in April 2018. That works out to a few thousand dollars per claim on average, before legal fees — Miller & Zois describes the payouts as “extremely low.” The IIH cases ended with judgment for Bayer and no group settlement.
The breast-cancer class action seeks the out-of-pocket cost of the device, not injury damages. No court has valued it. Dollar ranges on recruiting sites are not drawn from any Mirena IUD settlement. Our payout calculator shows how class funds are actually divided.
How cases like this one end
Our copy of the federal courts’ own case database covers 24,037 other fraud casesclosed in U.S. federal district courts between 2015 and 2025, 27.4% of them filed as class actions:
- 17.3% ended in a settlement recorded by the court. Another 22.5% were dismissed voluntarily, which often follows a private settlement — so the real settlement share sits between 17.3% and 39.8%.
- 10.4% were decided on a motion before any trial.
- 1 in 111 reached a trial (0.9%), after a median of 30 months.
- Median time from filing to the end of the case: 7 months.
- Only 735 of them (3.1%) record a money award at all; the median of those is $663,000.

October 2026 — No Open Settlement
As of October 2026 there is no Mirena IUD settlement, claim form or deadline. The Copeland class has not been certified, as far as we could find.
Three Things to Watch For
A well-known brand with old settlement headlines and no open claim process attracts misleading pitches:
“Claim your Mirena settlement payment”
The $12.2 million perforation deal covered people who already had filed cases, and it closed years ago. There is no Mirena claim portal. A site asking for your Social Security number or a fee to “release” a Mirena payout is not a court administrator.
Ads quoting big per-person amounts
Recruiting pages still show settlement ranges for perforation and IIH cases. Those cases ended with expert evidence excluded and appeals lost. Ask any firm which court and case number your claim would go into, and what happened to the earlier cases.
“You are already in the breast-cancer class”
We found no class certification in Copeland, and it seeks the cost of the device, not cancer damages. A caller saying you qualify for a cancer payout from it, or asking for medical records to “register,” is overstating what exists.
Mirena IUD Lawsuit — Questions People Actually Ask
Is there a Mirena IUD lawsuit I can join in 2026?
There is no group settlement to join. As of October 2026, the only Mirena class action we could find is Copeland v. Bayer (N.D. Cal., No. 5:24-cv-03042), which concerns breast cancer risk and covers people who paid out of pocket for the device. We found no class certification, but could not confirm the current docket. You do not sign up for a class action; if a class is certified, notice is sent by the court.
Is there a Mirena IUD settlement with a claim form?
No. The only public Mirena IUD settlement was the $12.2 million perforation deal offered in August 2017, which resolved cases that were already filed. There is no open claim form and no deadline.
What happened to the Mirena perforation lawsuits?
The federal perforation cases were dismissed in 2016 after the judge rejected the plaintiffs’ expert testimony, and the Second Circuit affirmed in 2017. Bayer then offered $12.2 million to settle some perforation claims, per Drugwatch.
What happened to the pseudotumor cerebri (IIH) lawsuits?
They lost. Judge Paul A. Engelmayer excluded the plaintiffs’ general-causation experts and granted summary judgment for Bayer. The Second Circuit affirmed on December 8, 2020. There was no group settlement for IIH claims.
Does the breast-cancer case pay people who got cancer?
Not as filed. The complaint seeks relief for women who paid an out-of-pocket cost for Mirena, on the theory they would not have bought it with a proper warning. Anyone with a breast cancer diagnosis who wants injury damages would need an individual claim, with a lawyer, within their state’s deadline.
Does this cover Kyleena, Skyla or Paragard?
No. The Copeland complaint is about Mirena. Kyleena is covered on our Kyleena lawsuit page. Paragard is a copper IUD from a different maker with its own active litigation over devices breaking at removal.
Can I still file an individual Mirena lawsuit?
Anyone can file, but Miller & Zois, a firm that once took these cases, says it no longer does, and Drugwatch reports most lawyers have stopped accepting them. Federal courts have twice ruled the plaintiffs’ causation evidence inadequate. State deadlines usually run from when you knew of the injury.
I got a call or letter about a Mirena payout. Is it real?
Probably not. There is no open Mirena IUD settlement as of October 2026. Real class notices name the court and case number and never charge a fee. Check the case number against the court record before giving out any information.
Separate from this case: were you injured in the last 2 years?
Class-action payouts are fixed amounts through an administrator. A personal injury claim is a different case — and often worth far more. Free estimate, no obligation.
