What Is TDF?

Tenofovir Disoproxil Fumarate is an antiviral medication used to treat and control HIV. TDF suppresses the amount of HIV in the body, so your immune system functions better. Gilead has sold TDF under the brand names:

TDF is not a cure for HIV. Instead, it helps keep the virus under control and helps prevent it from escalating into AIDS.

TDF belongs to a class of HIV medicines known as nucleoside reverse transcriptase inhibitors (NRTIs). They work by blocking an HIV enzyme called reverse transcriptase. With this mechanism, TDF prevents the HIV virus from multiplying and significantly reduces its amount in the body. This drug has helped HIV patients live longer and decreased their likelihood of spreading the disease to others.

There is a strong downside of taking TDF because it has a very low bioavailability, which means the body does not readily absorb it. So, extremely high doses of TDF are necessary for it to be effective. Because of the high doses used, studies have linked it to an increased risk of causing kidney and bone damage.

Why Are Florida Residents Filing TDF Lawsuits?

According to the LA Times, Gilead knew about the drug’s ability to cause bone and kidney damage before obtaining FDA approval to sell TDF. Worse yet, while Gilead was getting FDA approval to sell TDF, it was simultaneously researching a different version of the drug called TAF. This other drug was more effective against HIV and was far less likely to cause kidney or bone damage. Gilead chose to sell TDF instead of the TAF, the safer and more effective alternative.

The TDF lawsuits allege Gilead executives knowingly exposed HIV patients to the increased risk of kidney and bone damage caused by TDF instead of immediately bringing TAF to market. Gilead obtained a patent on TDF, preventing other drug companies from selling its generic version. Gilead then sold TDF without competition until the patent ran out. Once the patent expired, Gilead applied for and received FDA approval to sell TAF, the more effective and safer drug. Because Gilead has a patent on TAF, it can now sell it without competition until its expiration.

Scientific Studies Demonstrate TDF Is Toxic to Bones and Kidneys

The original formulation of the drug was administered intravenously. In 1997, Gilead found a way to turn it into a pill. TDF lawyers allege that Gilead knew as early as year 2000 that prolonged use of TDF’s pill version in high doses would cause severe kidney and bone damage. After the drug’s commercial release in 2001, non-Gilead scientists began studying its side effects. The scientists involved in the research confirmed what Gilead allegedly already knew. Below are some of the current results of those studies:

Bone Damage

  • In 2018, TDF treatment was linked to bone density loss. Researchers concluded that switching to another HIV drug caused bone density loss to improve.
  • In 2016, TDF was found to cause a one to three percent larger bone mineral density loss than other HIV medications.
  • In 2015, HIV patients that received drugs other than TDF were found to have significantly fewer kidney and bone health issues.
  • In 2010, a strong correlation was found between ingesting TDF and bone density loss.

Kidney Damage

  • In 2018, TDF was found to impact the renal function of HIV patients with Hepatitis B.
  • In 2017, researchers found that TDF use over time is significantly associated with the development of chronic kidney disease.
  • In 2013, a link between TDF and kidney disease was found.
  • In 2010, TDF was associated with a significant loss of kidney function.


Gilead Knew TAF Was Safer Than TDF as Early as 2001

TDF lawsuits allege that Gilead was already working on finding a safer alternative to TDF when it began selling the drug in 2001. In April of 2001, it published research of TAF that showed it was much more effective at treating HIV and that it might be far less toxic. Gilead even paid doctors to use TAF in small clinical trials. Although the results were promising, Gilead chose not to publish them. Instead, in 2004, Gilead chose to abruptly end its research into TAF while making billions of dollars selling TDF.

In 2009, as TDF’s patent was expiring, Gilead suddenly began researching TAF again. By 2015, FDA approved TAF for commercial use. At that time, Gilead started encouraging doctors to switch their patients to TAF to reduce the possible harm to their kidneys and bones.

Injuries Associated With TDF

TDF lawyers believe that patients can sustain the following injuries by taking TDF:

  • Kidney failure
  • Kidney damage
  • Acute Kidney disease
  • Chronic Kidney disease
  • Fanconi syndrome
  • Tubular dysfunction
  • Osteoporosis
  • Osteopenia
  • Bone fractures
  • Bone loss

You Can Receive Compensation for Your Injuries

TDF has the potential to impact the lives of innocent HIV patients in many ways. They may incur different types of kidney diseases and bone damages which may take extensive medical care. A Florida attorney from Distasio Law Firm can help you recover compensation for expenses associated with TDF-related treatments through a lawsuit.

Some of the damages you can seek to recover include costs for medications, dialysis, surgeries, hospitalizations, medical equipment, diagnostic testing, and more.

You can also obtain compensation for lost wages or a reduction in earning capacity if the prolonged use of TDF caused it.

Additionally, you can receive damages for pain and suffering you have suffered from the side effects of TDF use. This includes compensation for insomnia, chronic pain, depression, mental anguish, loss of mobility, and more.

If a loved one has died from the side-effects of TDF, their loved ones may also be eligible to receive compensation for funeral expenses, loss of companionship, and more.

How to Prove a TDF Drug Caused You Harm

If you took a TDF-containing drug that you think is responsible for your current health injuries, there are several pieces of evidence you can use to build your case. Your lawyer will collaborate with you in obtaining necessary evidence and demonstrating to the culpable insurance company or judge how this drug caused you damages.

Some of the types of evidence that can be used for this purpose include:

  • Medication receipts
  • Medical records that show that you were prescribed a TDF drug
  • Medical records that document your physical and mental health struggles
  • Financial records that show wage loss or change in employment
  • Photographs of your injuries

Along with the evidence, your attorney will also be able to gather testimonies and statements from medical experts and eyewitnesses to develop a compelling claim for you.
