If you took Tepezza (teprotumumab) for thyroid eye disease and suffered hearing loss, tinnitus, or other serious side effects, you may be entitled to significant compensation. Thousands of patients have filed lawsuits against Horizon Therapeutics (now Amgen), alleging the company failed to warn about the risk of permanent hearing damage. Choosing the right Tepezza lawyer can make the difference between a fair settlement and a missed opportunity. This guide explains how to find the best Tepezza attorney, what these cases cost, and what your claim may be worth in 2026.

What Is a Tepezza Lawsuit?

Tepezza was approved by the FDA in January 2020 as the first and only drug for thyroid eye disease (TED) — a rare autoimmune condition that causes bulging eyes, double vision, pain, and vision loss. The drug quickly became a blockbuster, generating billions in sales. But many patients soon reported a troubling side effect: hearing problems.

Tepezza lawsuits allege that Horizon Therapeutics knew — or should have known — that Tepezza could cause hearing loss, tinnitus, and other auditory damage, but failed to adequately warn patients and doctors. The lawsuits claim:

  • Failure to warn: The original drug label did not mention hearing loss as a potential side effect, even though clinical trials showed hearing-related adverse events.
  • Defective design: The drug's mechanism of action — blocking insulin-like growth factor-1 receptor (IGF-1R) — can damage the inner ear, which relies on IGF-1 for hearing function.
  • Negligent marketing: The company aggressively marketed Tepezza without disclosing the full scope of hearing risks.
  • Breach of duty: The manufacturer had a duty to conduct adequate safety testing and to update warnings as evidence of harm emerged.

In 2023, the FDA required Horizon to update Tepezza's label to include a warning about the risk of hearing impairment. By then, thousands of patients had already suffered hearing damage — some permanent. Tepezza lawsuits have been consolidated into a federal multidistrict litigation (MDL No. 3069) in the Northern District of Illinois, where bellwether trials are helping to establish settlement values.

Who Can File a Tepezza Lawsuit?

You may qualify for a Tepezza lawsuit if you:

  • Received one or more Tepezza infusions for thyroid eye disease
  • Developed hearing loss, tinnitus, deafness, or other hearing problems during or after treatment
  • Were not warned about the risk of hearing damage before starting treatment
  • Suffered financial losses, medical expenses, or diminished quality of life as a result

Eligible hearing injuries include: sensorineural hearing loss, conductive hearing loss, tinnitus (ringing in the ears), hyperacusis (sensitivity to sound), deafness (partial or total), and the need for hearing aids or cochlear implants. Even if your hearing loss was diagnosed months after your last infusion, you may still have a valid claim — the statute of limitations generally starts when you discovered (or should have discovered) the connection between Tepezza and your injury.

Family members of patients who died from complications related to Tepezza may also file wrongful death claims. If you are unsure whether you qualify, a free case review with a Tepezza hearing loss lawyer can help you determine your eligibility.

Why Tepezza Cases Differ From Ordinary Injury Claims

Tepezza lawsuits are complex pharmaceutical mass torts — not simple personal injury cases. They differ in several important ways:

  • Multidistrict litigation (MDL): Tepezza cases are consolidated in federal MDL, where pretrial proceedings are coordinated. Your lawyer must understand MDL procedure, common benefit assessments, and bellwether trial strategy.
  • Scientific complexity: Proving causation requires expert testimony on pharmacology, audiology, and the IGF-1R pathway. Your lawyer needs access to qualified medical experts.
  • Corporate defendant: You are up against Amgen, one of the world's largest pharmaceutical companies, with virtually unlimited legal resources. Your lawyer needs the financial strength and experience to go toe-to-toe with a corporate giant.
  • Long timelines: Pharmaceutical mass torts typically take 2–5 years to resolve. Patience and persistence are essential.
  • Medical records: Your case depends on detailed medical records — infusion records, audiology tests, ENT evaluations, and treatment history. Your lawyer must know how to gather and organize this evidence.

Do You Need a Tepezza Lawyer?

Technically, you can file a lawsuit on your own — but in a pharmaceutical mass tort, that is almost never advisable. Here is why a specialized Tepezza lawyer matters:

  • MDL navigation: Filing in the correct court, meeting MDL deadlines, and complying with court orders requires specialized knowledge.
  • Expert witnesses: You need audiologists, pharmacologists, and medical experts to prove causation. Experienced firms already have these experts lined up.
  • Settlement leverage: Pharmaceutical companies settle when they face organized, well-prepared litigation. A solo plaintiff has little leverage.
  • Case valuation: An experienced lawyer knows what similar cases have settled for and can negotiate accordingly.
  • No upfront cost: Tepezza lawyers work on contingency — you pay nothing unless you win.

If you suffered hearing loss after Tepezza, the cost of not hiring a lawyer could be enormous. Pharmaceutical companies have teams of attorneys whose job is to minimize payouts. You deserve someone fighting just as hard for you.

What a Tepezza Lawyer Does

A qualified Tepezza attorney handles every aspect of your case:

  1. Free case evaluation: Reviews your medical history, infusion records, and hearing damage to determine if you have a valid claim.
  2. Evidence gathering: Collects medical records, audiology tests, pharmacy records, and infusion logs. Orders independent medical examinations if needed.
  3. Expert consultation: Works with audiologists, ENTs, and pharmacologists to establish causation between Tepezza and your hearing loss.
  4. Filing your claim: Files your lawsuit in the appropriate court and ensures compliance with MDL procedures and deadlines.
  5. Discovery: Obtains internal company documents, clinical trial data, and marketing materials through the MDL discovery process.
  6. Negotiation: Negotiates with Amgen's attorneys for a fair settlement, using bellwether trial results and comparable case values as leverage.
  7. Trial representation: If a fair settlement is not offered, takes your case to trial and presents your evidence to a jury.
  8. Settlement distribution: Ensures you receive your compensation promptly and handles any medical liens or subrogation claims.

How to Choose the Best Tepezza Lawyer: 10 Key Factors

1. Pharmaceutical Mass Tort Experience

Tepezza cases are not ordinary personal injury claims. Look for a firm with a proven track record in pharmaceutical litigation — especially drug injury MDLs. Ask: How many pharmaceutical mass tort cases have you handled? Are you actively involved in the Tepezza MDL? Have you handled cases against major drug manufacturers?

2. Tepezza-Specific Knowledge

Your lawyer should understand Tepezza's mechanism of action, the IGF-1R pathway, the FDA approval history, the label change timeline, and the specific hearing injuries associated with the drug. A lawyer who has already handled Tepezza cases will be far ahead of one learning on your case.

3. MDL Participation

The best Tepezza lawyers are actively participating in MDL No. 3069 — serving on plaintiffs' steering committees, attending court conferences, and contributing to common benefit work. This gives them access to the latest discovery, settlement negotiations, and bellwether trial intelligence. Ask whether the firm has a leadership role in the MDL.

4. Medical Expert Network

Your case lives or dies on expert testimony. Top firms have established relationships with audiologists, otolaryngologists (ENTs), pharmacologists, and epidemiologists who can testify about causation. Ask: What experts do you work with? Have they testified in Tepezza or similar drug cases?

5. Track Record and Results

Look for a firm with a history of significant pharmaceutical settlements and verdicts. While past results do not guarantee future outcomes, they indicate the firm's ability to handle complex litigation. Ask about specific results in drug injury cases — not just general personal injury settlements.

6. Resources and Financial Strength

Pharmaceutical mass torts are expensive. Expert witnesses, medical record retrieval, and years of litigation cost hundreds of thousands of dollars per case. Your firm must have the financial resources to fund your case through trial if necessary — without cutting corners or pressuring you to accept a low settlement.

7. Communication and Transparency

You should receive regular updates on your case, honest assessments of its strengths and weaknesses, and prompt responses to your questions. Avoid firms that are hard to reach, use high-pressure tactics, or make unrealistic promises. During your free consultation, note how clearly the lawyer explains the process and whether they listen to your concerns.

8. Fee Transparency

Reputable Tepezza lawyers work on a contingency fee basis and clearly explain all costs upfront — including the contingency percentage, case expenses, and any MDL common benefit assessment. Get the fee agreement in writing before signing. If a lawyer is vague about fees, walk away.

9. Who Actually Handles Your Case

Some large firms sign up thousands of clients and then hand cases off to less experienced attorneys or paralegals. Ask: Who will be my primary point of contact? Will a senior attorney handle my case? How many Tepezza cases has that attorney personally worked on?

10. Honest Case Assessment

A good lawyer will be honest about the strengths and weaknesses of your case, the expected timeline, and realistic settlement ranges. Be wary of anyone who guarantees a specific outcome or settlement amount — no lawyer can predict results with certainty.

Questions to Ask During Your Free Consultation

Most Tepezza lawyers offer free consultations. Use this opportunity to evaluate the firm. Ask:

  1. How many Tepezza cases have you handled?
  2. Are you involved in the Tepezza MDL? What role do you play?
  3. What hearing injuries qualify for a Tepezza lawsuit?
  4. What is the statute of limitations in my state?
  5. What is your contingency fee? What case costs will I be responsible for?
  6. What is the MDL common benefit assessment, and how does it affect my settlement?
  7. How long do Tepezza cases typically take to resolve?
  8. What is a realistic settlement range for a case like mine?
  9. Who will be my primary contact, and how often will I receive updates?
  10. Have you taken pharmaceutical cases to trial? What were the results?

Red Flags to Avoid

  • Guaranteed results: No lawyer can guarantee a settlement amount or outcome.
  • Upfront fees: Reputable Tepezza lawyers work on contingency. Never pay upfront.
  • High-pressure tactics: If a firm pressures you to sign immediately, walk away.
  • No MDL involvement: A firm with no connection to the Tepezza MDL may lack critical information and leverage.
  • Vague about fees: If the lawyer will not clearly explain fees in writing, find someone else.
  • Poor communication: If the firm is hard to reach during the consultation phase, it will not improve later.
  • Out-of-state firms with no local presence: Your firm should be licensed to practice in your state or partnered with local counsel.

How Much Does a Tepezza Lawyer Cost in 2026?

Tepezza lawyers work on a contingency fee basis — you pay nothing upfront, and the lawyer only gets paid if you win your case. Here is how the costs break down:

Contingency Fees: 33%–40%

The standard contingency fee for pharmaceutical mass tort cases is 33% to 40% of your gross settlement or verdict. Most Tepezza lawyers charge 33.33% (one-third) if the case settles before trial, and up to 40% if it goes to trial. The exact percentage should be clearly stated in your fee agreement.

Case Costs: $15,000–$150,000+

Litigating a pharmaceutical case is expensive. Case costs may include:

  • Medical record retrieval ($500–$2,000)
  • Expert witness fees ($10,000–$100,000+)
  • Court filing fees ($400–$500)
  • Deposition costs ($5,000–$20,000)
  • Travel expenses
  • MDL common benefit assessment (see below)

In most cases, the law firm advances these costs and deducts them from your settlement. If you lose, you typically owe nothing — but confirm this in your fee agreement. Some firms charge costs even if you lose; the best firms do not.

MDL Common Benefit Assessment: 4%–8%

In multidistrict litigation, the court may order a common benefit assessment — typically 4% to 8% of each settlement — to compensate the attorneys who performed work benefiting all plaintiffs (discovery, expert development, bellwether trials). This assessment is deducted from your settlement in addition to your lawyer's contingency fee. Your lawyer should explain exactly how this works.

Worked Example: $250,000 Settlement

Suppose your Tepezza case settles for $250,000. Here is how the money might break down:

  • Gross settlement: $250,000
  • Attorney contingency fee (33.33%): −$83,325
  • MDL common benefit assessment (6%): −$15,000
  • Case costs (advanced by firm): −$25,000
  • Medical liens (if any): −$10,000
  • Net to you: $116,675

Your actual net recovery depends on your settlement amount, fee percentage, case costs, and medical liens. Always ask your lawyer for a written estimate of your net recovery before accepting any settlement.

Free Consultations

Every reputable Tepezza lawyer offers a free case evaluation — no obligation, no cost. Use this to assess the firm and your case before committing. You should never pay for an initial consultation in a pharmaceutical mass tort case.

What If You Lose?

With a true contingency fee arrangement, you owe nothing if you lose — no attorney fees, no case costs. Confirm this in writing. Some firms use a modified arrangement where you may owe case costs even if you lose. The best firms absorb all costs if your case is unsuccessful.

What Compensation Can You Recover?

Tepezza lawsuit compensation may include:

  • Medical expenses: Audiology tests, hearing aids, cochlear implants, ENT visits, surgeries, medications, and future medical care.
  • Lost wages: Income lost due to hearing problems, missed work, or reduced earning capacity.
  • Pain and suffering: Physical pain, emotional distress, anxiety, depression, and diminished quality of life.
  • Loss of enjoyment of life: Inability to enjoy conversations, music, social activities, or hobbies due to hearing loss.
  • Permanent disability: Compensation for permanent hearing damage that affects your daily life and career.
  • Punitive damages: In some cases, if the court finds the manufacturer acted with reckless disregard for patient safety, punitive damages may be awarded to punish the company.

Tepezza Settlement Value Ranges (2026)

Settlement values depend on the severity of your hearing loss, the duration of your Tepezza treatment, your age, and the impact on your life and career. While every case is unique, here are general ranges based on reported outcomes and comparable pharmaceutical settlements:

  • Mild hearing loss / tinnitus (resolved): $50,000–$150,000
  • Moderate hearing loss (hearing aids required): $150,000–$400,000
  • Severe / permanent hearing loss: $400,000–$1,000,000+
  • Total deafness / cochlear implant: $750,000–$2,000,000+

These are estimates, not guarantees. Bellwether trial results in the Tepezza MDL will help establish more precise settlement values. Your lawyer can provide a more specific estimate based on the details of your case.

The Tepezza Lawsuit Process: 8 Steps

  1. Free case evaluation: A lawyer reviews your medical records and determines if you qualify.
  2. Filing your lawsuit: Your attorney files a complaint in federal court. Your case is transferred to the Tepezza MDL in the Northern District of Illinois.
  3. Discovery: Both sides exchange evidence — medical records, company documents, clinical trial data, and expert reports. This phase typically takes 12–24 months.
  4. Expert depositions: Medical experts are deposed about causation, damages, and the standard of care.
  5. Bellwether trials: A small number of representative cases go to trial. The results help both sides gauge settlement values.
  6. Settlement negotiations: Based on bellwether results, the parties negotiate a global settlement or individual settlements.
  7. Settlement or trial: Most cases settle. If yours does not, it proceeds to an individual trial.
  8. Compensation: You receive your settlement, minus attorney fees, costs, and any medical liens.

Tepezza Lawsuit Timeline

Pharmaceutical mass torts take time. Here is a realistic timeline:

  • Case evaluation and filing: 1–3 months
  • Discovery: 12–24 months
  • Bellwether trials: 6–18 months
  • Settlement negotiations: 3–12 months
  • Total: 2–5 years from filing to resolution

While this timeline may seem long, it reflects the complexity of pharmaceutical litigation and the need to build a strong case. Your lawyer should keep you informed at every stage and set realistic expectations.

Statute of Limitations for Tepezza Lawsuits

Every state has a statute of limitations — a deadline for filing a lawsuit. For drug injury cases, the statute typically ranges from 1 to 6 years, depending on the state. In most states, the clock starts when you discovered (or reasonably should have discovered) that Tepezza caused your hearing loss — not when you received your first infusion.

Important: If you miss the deadline, you lose your right to compensation permanently. Because the discovery rule and state-specific exceptions can be complex, contact a Tepezza lawyer as soon as possible to determine your deadline. Do not wait — even if you are unsure whether you have a case.

Individual Lawsuit vs. Class Action vs. MDL

Tepezza cases are handled as an MDL (multidistrict litigation), not a class action. Here is the difference:

  • Individual lawsuit: You file your own case. You control your claim and receive compensation based on your specific injuries. In an MDL, your case remains individual — you are not lumped together with other plaintiffs.
  • Class action: One lawsuit represents a large group. All members receive the same (or similar) compensation. Tepezza cases are NOT class actions.
  • MDL: Individual cases are consolidated for pretrial proceedings (discovery, expert testimony) to save time and resources. Each case retains its own value based on individual injuries. If a settlement is reached, compensation is allocated based on the severity of each plaintiff's injuries. This is the best of both worlds — efficiency plus individualized compensation.

Steps to Take After a Tepezza Hearing Injury

  1. See a doctor immediately: Visit an audiologist or ENT specialist. Get a comprehensive hearing test and document your symptoms.
  2. Preserve your records: Keep all medical records, infusion logs, pharmacy receipts, and correspondence with your doctors.
  3. Do not stop treatment without talking to your doctor: If you are still receiving Tepezza, discuss the risks and benefits with your physician before discontinuing.
  4. Document your symptoms: Keep a journal of your hearing problems — when they started, how they affect your daily life, and any treatments you have tried.
  5. Contact a Tepezza lawyer: Get a free case evaluation as soon as possible to protect your rights and meet the statute of limitations.

Common Mistakes to Avoid

  • Waiting too long: The statute of limitations may expire. Contact a lawyer promptly.
  • Signing a settlement without a lawyer: The manufacturer may offer a quick, low settlement. A lawyer can negotiate for much more.
  • Posting on social media: Do not discuss your case, injuries, or settlement online. The defense may use your posts against you.
  • Choosing the wrong lawyer: A general personal injury lawyer without pharmaceutical experience may not understand MDL procedure or the science behind Tepezza cases.
  • Not documenting your injuries: Without medical records and audiology tests, your case is much weaker.
  • Missing medical appointments: Gaps in treatment can be used to argue your injuries are not serious.

Tepezza Lawyer vs. General Personal Injury Lawyer

While any licensed attorney can technically handle a Tepezza case, a specialized Tepezza hearing loss lawyer offers significant advantages:

  • Deep understanding of the drug, its mechanism, and the hearing injuries it causes
  • Active participation in the Tepezza MDL with access to the latest discovery and settlement intelligence
  • Established relationships with audiology and pharmacology experts
  • Experience negotiating with pharmaceutical companies
  • Knowledge of MDL procedure, common benefit assessments, and bellwether strategy

A general personal injury lawyer — even an excellent one — may lack these specialized resources. For a complex pharmaceutical mass tort, specialization matters.

How to Find a Tepezza Lawyer Near You

  • Online search: Search for "Tepezza lawyer near me" or "best Tepezza attorney" and review firm websites, case results, and client reviews.
  • MDL court records: Check the Tepezza MDL docket for firms serving on the plaintiffs' steering committee — these are the firms leading the litigation.
  • State bar association: Verify the lawyer's license and disciplinary history through your state bar.
  • Referrals: Ask other Tepezza patients, support groups, or your doctor for recommendations.
  • Free consultations: Interview 2–3 firms before choosing. Compare their experience, communication style, and fee structures.

Most Tepezza lawyers handle cases nationwide — you do not need to find a lawyer in your city. What matters is the firm's MDL involvement, pharmaceutical experience, and track record.

Frequently Asked Questions

How much is a Tepezza lawsuit worth?

Settlement values vary based on the severity of your hearing loss, treatment duration, and impact on your life. Mild cases may settle for $50,000–$150,000, while severe permanent hearing loss cases may exceed $1,000,000. Your lawyer can provide a more specific estimate after reviewing your medical records.

How long does a Tepezza lawsuit take?

Most pharmaceutical mass torts take 2–5 years from filing to resolution. The Tepezza MDL is still in the discovery and bellwether phase. Your lawyer can provide a more current timeline estimate based on the MDL's progress.

Do I have to pay anything upfront?

No. Reputable Tepezza lawyers work on contingency — you pay nothing upfront and owe nothing unless you win.

What if I stopped taking Tepezza years ago?

You may still have a valid claim. The statute of limitations generally starts when you discovered the connection between Tepezza and your hearing loss, not when you stopped treatment. Contact a lawyer to determine your deadline.

Can I file if my hearing loss is mild?

Yes. Even mild hearing loss or tinnitus may qualify for compensation, especially if it required medical treatment or affected your quality of life. A free case evaluation can determine your eligibility.

What if I signed a consent form?

Signing a consent form does not waive your right to sue if the manufacturer failed to warn about the specific risk of hearing loss. The original Tepezza consent forms and labels did not adequately disclose hearing risks.

The Bottom Line

If Tepezza caused your hearing loss, you deserve compensation — and the right lawyer can help you get it. Look for a Tepezza lawyer with pharmaceutical mass tort experience, active MDL participation, a strong expert network, transparent fees, and a proven track record. Take advantage of free consultations, ask tough questions, and choose a firm that communicates clearly and fights hard for its clients.

Time matters. The statute of limitations may be running, and evidence is easiest to gather sooner rather than later. Contact a qualified Tepezza attorney today for a free case evaluation. You pay nothing unless you win — and you owe it to yourself to explore your options.
