What is Truvada?
As claimed by the manufacturer, Truvada (tenofovir disoproxil fumarate TDF) is one of several pre-exposure prophylaxis medications that are currently used to treat human immunodeficiency virus (HIV) and hepatitis B virus infection [1].
The drug is sometimes considered a safer HIV drug for some people who do not have HIV infection (for example, those who do not always use condoms or who have a sex partner that has HIV infection) to help reduce their chances of getting an HIV infection. Truvada was approved by the U.S. Food and Drug Administration in 2012.
How Does it Work?
Truvada prevents HIV infection by blocking the virus’s ability to replicate inside human cells. Understanding how Truvada works can help individuals make informed decisions about its use and effectiveness in HIV prevention.
Detailed Comparison of TDF vs. TAF Effectiveness
Drug Interaction Information
Since Truvada is primarily processed through the kidneys, certain medications can interfere with its effectiveness or increase the risk of side effects.
Medications That Require Caution with Truvada
- NSAIDs (e.g., ibuprofen, naproxen) – May increase kidney strain.
- Other HIV medications – Taking Truvada alongside certain antiretrovirals can lead to higher tenofovir levels, increasing toxicity risks.
- Medications for Hepatitis B – Truvada also treats Hepatitis B, so stopping it abruptly could cause severe flare-ups in people with HBV.
By understanding how Truvada works and following best practices for adherence, individuals can take full advantage of its life-changing benefits while minimizing risks.
What’s the Problem with HIV Treatment Drugs?
According to the Clinicalinfo.HIV.gov research from 2023, Truvada side effects can be [2]:
- Acute or chronic kidney disease – When damage to the kidneys prevents them from filtering blood properly. Anything below 90 GFR (glomerular filtration rate) is abnormal. Truvada‘s “poor bioavailability” keeps the body from efficiently absorbing the drugs. This leads to kidney problems and kidney injuries.
- Kidney failure – occurs when kidney disease is left untreated. Patients would then need a kidney transplant or dialysis to filter waste from their blood. Kidney function failure can be acute or chronic.
- Fanconi Syndrome – Occurs when impaired kidney tubule function affects the urine’s chemical makeup. This includes abnormal protein levels in the urine, called proteinuria. Fanconi Syndrome can lead to kidney damage and bone loss.
- Osteopenia – Medical condition characterized by weakened bone mineral density (including teeth). If left untreated, it could lead to breaks and fractures.
- Osteoporosis – occurs when bones become brittle and fracture easily.
- Osteomalacia – When bones break down more quickly than they can re-form.
Judge Clears Suit Alleging Gilead HIV Drugs Defectively Designed
U.S. District Judge Jon S. Tigar has allowed a lawsuit against Gilead Sciences Inc. to proceed, filed by a group of patients accusing the company of negligence, product liability, and defective drug design.
However, he dismissed allegations that Gilead intentionally hid knowledge that its tenofovir disoproxil fumarate (TDF)-based HIV drugs were “unreasonably and unnecessarily unsafe.”
Despite this, key claims remain in the case, including:
- Design defect – Plaintiffs argue that TDF drugs had a flawed formulation that led to serious health risks.
- Negligence – The lawsuit claims Gilead failed to act responsibly in designing, testing, and warning patients about risks.
- Product liability – Allegations include the failure to ensure patient safety and market a safer alternative (TAF) sooner.
This lawsuit underscores growing concerns over the long-term safety of TDF-containing drugs like Truvada, especially their impact on kidney and bone health.
Scientific Findings on Truvada
Bone Density Loss Linked to Truvada
One recent study found that patients taking Truvada experienced bone mineral density (BMD) loss of 2-6% within the first two years of treatment.
The study also revealed that:
- This decline is particularly concerning for individuals at risk of osteoporosis or fractures.
- Long-term use may increase the likelihood of developing osteopenia or osteoporosis, requiring additional monitoring and preventive measures.
Given these findings, bone health screenings and calcium/vitamin D supplementation may be necessary for individuals on long-term Truvada therapy.
Kidney Function Decline and Truvada
A large-scale study conducted by researchers at the University of San Francisco examined 10,000 patients and found a direct link between Truvada and kidney complications, including [3]:
- Proteinuria – High levels of protein in urine, indicating kidney damage.
- Rapid decline in kidney function – Accelerated deterioration of renal filtration capacity.
- Chronic Kidney Disease (CKD) – Long-term kidney dysfunction, increasing the risk of kidney failure.
- Kidney failure – A life-threatening condition requiring dialysis or transplantation.
These findings support concerns raised in lawsuits that Gilead was aware of these risks but continued marketing TDF-based drugs without adequate warnings.
Increased Protein Levels in Urine (Proteinuria) in iPrEx Study
The iPrEx study, a major clinical trial on PrEP effectiveness, found no significant differences in markers of kidney damage between treatment arms.
However, in the iPrEx-OLE (open-label extension) study, more concerning data emerged:
- After 24 weeks on PrEP, patients experienced [4]:
- 21% increase in urine α1m levels (a marker of kidney damage)
- 18% increase in proteinuria (95% confidence interval: 8 to 28)
These results suggest that long-term PrEP use with TDF-based medications may lead to gradual kidney damage even in individuals without pre-existing conditions.
Given these findings, patients taking Truvada should undergo routine kidney function tests to monitor for early signs of deterioration, especially if they have pre-existing kidney issues or risk factors such as diabetes or hypertension.
Among the 200 participants included in the cross-sectional iPrEx substudy, the median age was 23 years and 18% of participants were transgender. Persons of black race comprised 11% of participants, whereas Asians and Latinos comprised 27% and 54% of participants, respectively. – Stated the National Center for Biotechnology Information.
Which Other HIV Medications Have Been Linked to These Side Effects?
Truvada and other tenofovir disoproxil fumarate (TDF)-based drugs—including Atripla, Stribild, Complera, and Viread—are widely used for HIV treatment and prevention (PrEP).
While effective, these medications can cause a range of mild to severe side effects that patients should be aware of.
Understanding how these symptoms progress and the key risk factors can help individuals take proactive steps in managing their health while on these medications.
Early Warning Signs and Progression Timeline
Recognizing the early warning signs of side effects can prevent more serious complications from developing.
Mild Symptoms (First Few Weeks)
- Many individuals experience headaches, nausea, diarrhea, dizziness, fatigue, abdominal pain, and weight loss shortly after starting Truvada or similar drugs.
- Some may develop mild upper respiratory infections.
- These symptoms often resolve within the first month as the body adjusts to the medication.
Progression to More Serious Symptoms (Months to Years)
- Kidney problems may develop or worsen, especially in patients with pre-existing conditions.
- Bone density loss (osteopenia, osteoporosis, osteomalacia) can occur gradually, leading to an increased risk of fractures.
- Lactic acidosis, a rare but life-threatening condition, has been reported in post-marketing surveillance, though it was not observed in clinical trials.
Because some side effects take months or years to appear, regular monitoring is essential for early detection and management.
Risk Factors for Developing Complications
While anyone taking Truvada or similar TDF medications can experience side effects, certain individuals are at a higher risk of developing serious complications:
Pre-existing Kidney Conditions
- People with reduced kidney function are at a higher risk of developing renal impairment while on TDF-based drugs.
- These individuals should have their kidney function monitored more frequently.
Liver Disease and Hepatitis B
- Patients with liver disease should be cautious, as Truvada and similar drugs can cause liver toxicity.
- Those with Hepatitis B (HBV) who stop taking Truvada abruptly may experience a severe worsening of their liver disease.
Age and Bone Health
- Older adults naturally experience decreased bone density, making them more prone to osteoporosis and fractures when taking TDF medications.
- Individuals with a family history of osteoporosis should discuss preventative strategies with their doctor.
By identifying these risk factors early, patients can take steps to minimize potential complications while continuing their HIV treatment or prevention regimen.
Monitoring Requirements and Recommended Tests
Routine medical tests can help detect issues before they become serious, ensuring that individuals using Truvada or similar medications remain in optimal health.
Test | Purpose |
---|---|
Kidney Function Tests (eGFR, Creatinine Clearance) | Measure how well the kidneys are filtering waste. |
Urine Tests | Check for proteinuria, an early sign of kidney damage (Fanconi Syndrome). |
Bone Density Scans (DEXA Scan) | Assess bone mineral density, especially for long-term users. |
Liver Enzyme Tests (ALT, AST, Bilirubin Levels) | Detect potential liver damage or toxicity. |
Regular screening helps ensure that any potential side effects are identified and managed early, preventing long-term complications.
Prevention Strategies While on Truvada and Similar Medications
While Truvada and other TDF-based drugs can cause side effects, there are steps individuals can take to minimize these risks and maintain overall health:
-
Stay Hydrated: Drinking plenty of water supports kidney function and may help reduce the risk of renal impairment.
-
Support Bone Health: Consume calcium- and vitamin D-rich foods to maintain bone strength and engage in weight-bearing exercises to prevent bone density loss.
-
Limit Alcohol and NSAID Use: Excessive alcohol intake can worsen liver function, especially for those at risk, also avoid NSAIDs (e.g., ibuprofen, naproxen) unless prescribed, as they can strain the kidneys.
-
Attend Regular Medical Check-ups: Follow-up appointments help detect side effects before they become serious, ensuring long-term health.
By understanding early warning signs, key risk factors, and proper medical monitoring, individuals can stay proactive about their health while using these medications.
Are Truvada Lawsuits Being Filed?
Only a qualified attorney can determine whether you are eligible to file a dangerous drug lawsuit against Gilead Sciences Inc., the maker of Truvada, which is why we are currently offering free case evaluations.
Simply fill out the confidential evaluation form below to contact our law firm now to see if you qualify for Truvada Lawsuit Settlements.
Most cases involving pharmaceuticals allege that a drug was sold with design, manufacturing, and/or marketing defects, which typically refers to a company’s failure to warn of a certain side effect.
In the case of a Truvada Lawsuit, our attorneys suspect that patients may be able to take legal action in light of claims that Gilead failed to adequately warn consumers about the risk of kidney disease and bone loss.
Truvada Litigation
Truvada lawsuits have been consolidated in the Northern District of California in multidistrict litigation (MDL). This is where similar lawsuits are consolidated to speed up litigation and a settlement.
The Truvada Lawsuit MDL is called In Re. Tenofovir Disoproxil Fumarate Products Liability Litigation, MDL 2881. Currently, the first Bellwether trial is scheduled for June 2022.
Failure to Warn and Defective Design Claims
The bulk of the lawsuits deal with the claim that Gilead Sciences knew that Truvada carried serious design defects that caused severe side effects. Gilead also failed adequately to warn doctors or patients of those risks in its disclaimers.
The lawsuits claim that Gilead knew that the drug TDF was very toxic in the prescribed doses. The company even sought a safer version of it right after TDF was approved by the FDA in 2001. Nevertheless, Gilead continued to tout TDF and Truvada as “risk-free.”
The FDA reprimanded Gilead in 2002 and 2003 for false claims that TDF did not put a patient’s bone density or kidneys in jeopardy. Truvada continued to be marketed as a safe drug to maximize profits. This happened despite a growing body of scientific evidence to the contrary.
Claims that Gilead Withheld a Safer Drug
AIDS Healthcare Foundation Files Truvada Class Action Lawsuit
AIDS Health Foundation (AHF), the largest global AIDS organization, helped file the class action lawsuit on behalf of Devin Martinez, Ricardo Wohler, and others who purchased Truvada and other TDF drugs in May 2018.
This California class action lawsuit is separate from the individual injury lawsuits filed by people who suffered injuries from TDF, but it deals with similar issues.
According to the complaint, Gilead misrepresented TDF’s safety profile as early as 2001. The FDA even reprimanded Gilead in 2002 and 2003 for claiming the drug had no toxicities and would not cause bone or kidney damage, but the company continued to downplay the risks.
Allegations against Gilead in the class action include:
- Failing to disclose that TDF had a significant risk for toxicity and bone and kidney damage
- Failed to warn of the kidney and bone risks in all patients, not just those with preexisting kidney and bone problems
- Gilead misrepresented the risks and benefits of its TDF drugs to sell them
Has There Been a Recall?
Truvada is still available and has yet to be taken off the market. Despite the evidence linking the drug to several serious injuries, the FDA has not mandated a recall of the product.
If you are currently taking Truvada, talk to your doctor about other treatment options. Before stopping use, consult with your doctor to make sure that it is safe.
