An Experienced Texas Legal Team Handling Pharmaceutical Mass Tort Claims
Every day, millions of people put their trust in pharmaceutical companies, believing that the medicines they take will improve their health or save their lives. Unfortunately, these drugs sometimes cause more harm than good.
At KRW Lawyers, we can work tirelessly to uncover the truth behind dangerous pharmaceuticals and hold the responsible parties accountable for the harm they have caused through mass tort actions. A mass tort is a type of legal action that allows individuals harmed by a dangerous drug to pursue compensation alongside others who have experienced similar harm. By joining a mass tort, you gain the power of collective legal action while retaining your right to an individual claim. In other words, unlike a class action lawsuit, you can still recover compensation for your personal damages when you participate in a mass tort.
Our attorneys have experience navigating mass torts and can fight to protect your individual interests throughout each stage of the legal process. We aim to provide exceptional service, including transparent communication and results-driven advocacy that puts your needs first. You owe us no legal fees unless we help you recover damages.
If you suffered harm after using a pharmaceutical as intended, don’t wait to discuss your legal options with our San Antonio dangerous drug lawyers. A member of our team is available 24/7, so call (855) 770-4045 or contact us online to schedule a free consultation today.



When Is a Drug “Dangerous,” and When Am I Eligible to Join a Mass Tort?
A drug is considered "dangerous" if it causes unexpected harm or severe side effects, particularly when those risks outweigh the benefits of its intended use. Factors that contribute to a drug being dangerous include improper testing, undisclosed side effects, manufacturing defects, or incorrect labeling. A drug can also become hazardous if it interacts negatively with other medications or is prescribed in an improper dosage.
You may have a dangerous drug claim if you suffered harm directly linked to the use of such a drug. To have a valid claim, you must demonstrate that the drug caused harm due to negligence or failure on the part of a manufacturer, distributor, or healthcare provider. This may involve proving that a company ignored safety protocols during production, failed to communicate known risks, or misrepresented the product through marketing.
Joining a mass tort may make sense if your experience aligns with others who have suffered similar harm from the same medication. This option becomes particularly beneficial if the drug in question has caused widespread injuries or adverse effects that share common factors, such as a defect in the drug's design or inadequate warnings about risks. By participating in a mass tort, you can pool resources with others, making it more feasible to challenge powerful pharmaceutical companies or large organizations. Our San Antonio dangerous drug attorneys can review your circumstances and walk you through your legal options, including whether you are eligible to join a mass tort.
If you think you may have a claim, call (855) 770-4045 or contact us online to explore your legal options with our San Antonio dangerous drug attorneys.

-
One of the most significant issues linked to Abilify is its potential to cause compulsive behaviors, including gambling, shopping, eating, and hypersexuality. These behaviors can lead to severe financial and emotional consequences for individuals and their families. Additionally, some users have reported experiencing severe mood swings and withdrawal symptoms when discontinuing the medication.
-
Reports have linked Actemra to an increased risk of cardiovascular complications, such as heart attacks and strokes, as well as gastrointestinal perforations. Furthermore, some patients have experienced severe infections due to the medication’s immunosuppressive effects.
-
Gadolinium, a contrast agent commonly used in MRI scans, has been associated with several safety concerns. One of the primary issues is its potential to cause a rare condition known as nephrogenic systemic fibrosis (NSF) in patients with kidney dysfunction. Additionally, there is growing evidence that traces of gadolinium can remain in the body, including in the brain and other tissues, even in individuals with normal kidney function. While the long-term effects of these deposits are still being studied, these findings have raised questions about the overall safety of gadolinium-based contrast agents.
-
Imodium’s active ingredient, loperamide, works by slowing intestinal movement to reduce symptoms of diarrhea, but excessive use can lead to serious complications. One of the known issues with Imodium is its misuse at high doses, which can cause severe cardiac side effects, including arrhythmias and even cardiac arrest.
-
Invokana is a medication used to manage type 2 diabetes by lowering blood sugar levels. However, its use is associated with several known issues and potential risks. One significant concern is an increased risk of ketoacidosis, a serious condition where elevated levels of ketones in the blood can lead to severe complications if not addressed promptly. Additionally, Invokana has been linked to an increased risk of lower limb amputations, particularly in patients with existing risk factors, such as peripheral vascular disease or neuropathy.
-
One of the known issues associated with Invokana use is the increased risk of developing diabetic ketoacidosis (DKA). DKA is a serious and potentially life-threatening condition characterized by the buildup of ketones in the blood, which can occur even when blood glucose levels are not significantly elevated, a phenomenon known as euglycemic DKA. Symptoms of DKA may include nausea, vomiting, abdominal pain, confusion, and rapid breathing.
-
KEYTRUDA, also known as pembrolizumab, is an immunotherapy drug used to treat various cancers by enhancing the body’s immune response to target and eliminate cancer cells. This drug can sometimes cause the immune system to attack healthy tissues. Commonly reported side effects include fatigue, rash, and gastrointestinal issues, such as diarrhea or constipation. More severe complications may involve inflammation of critical organs, such as pneumonitis (lungs), hepatitis (liver), nephritis (kidneys), or endocrinopathies (glands).
-
Limbrel 500, a prescription medical food previously used for the management of osteoarthritis, has been associated with certain adverse effects that led to significant concerns regarding its safety. Known issues include reports of liver injury and hypersensitivity pneumonitis, a condition that inflames the lungs. Symptoms of liver injury may include jaundice, dark urine, nausea, fatigue, and abdominal pain. Hypersensitivity pneumonitis symptoms can encompass coughing, difficulty breathing, and fever.
-
Nuedexta, a medication primarily prescribed for the treatment of pseudobulbar affect (PBA), can trigger heart rhythm abnormalities, particularly in individuals with pre-existing cardiac conditions or those taking medications that affect heart rate.
-
Nuplazid (pimavanserin) is an atypical antipsychotic medication primarily prescribed for the treatment of hallucinations and delusions associated with Parkinson’s disease psychosis. One of the primary concerns with this drug is the increased risk of mortality in elderly patients with dementia-related psychosis, a warning highlighted in the drug’s labeling. Additionally, some patients have reported side effects like nausea, peripheral edema, confusion, and hallucinations, which may exacerbate existing symptoms in sensitive populations.
-
Ocaliva is a medication used for the treatment of primary biliary cholangitis (PBC). Some patients have reported side effects like severe itching (pruritus), abdominal discomfort, fatigue, and rash, which can significantly impact quality of life. Additionally, Ocaliva carries warnings about potential liver-related complications, particularly in patients with advanced liver disease, such as decompensated cirrhosis. Misuse or improper dosing of Ocaliva in this population has been linked to serious liver injury and even fatal outcomes.
-
Onglyza (saxagliptin) is used to manage type 2 diabetes but has faced scrutiny due to dangerous associated risks. Studies have suggested a potential link between Onglyza and an increased risk of heart failure, particularly in patients with pre-existing cardiovascular conditions. Additionally, some users have reported serious side effects, such as respiratory infections, joint pain, and gastrointestinal discomfort.
-
PPIs are meant to treat conditions like acid reflux and ulcers. However, prolonged usage of PPIs has been associated with an increased risk of bone fractures, kidney disease, and vitamin B12 deficiency. Additionally, there is emerging evidence suggesting that PPIs may alter gut microbiota, potentially contributing to infections.
-
Risperdal (risperidone) is an antipsychotic medication used to treat conditions like schizophrenia, bipolar disorder, and irritability associated with autism, but it has been linked to several side effects and complications. One notable concern is the increased risk of developing extrapyramidal symptoms, such as tremors and muscle stiffness. Additionally, Risperdal has been associated with elevated prolactin levels, which can lead to issues like gynecomastia (breast tissue enlargement in males) and menstrual irregularities. Long-term use may also carry a risk of weight gain, metabolic changes, and an increased likelihood of diabetes.
-
Tasigna (nilotinib) is designed to treat certain types of leukemia but has the potential to cause QT prolongation, a condition that can lead to serious heart rhythm disturbances. Patients taking Tasigna may also experience elevated cholesterol levels, liver enzyme abnormalities, and a higher risk of pancreatitis. Furthermore, it has been linked to peripheral arterial occlusive disease, which can result in reduced blood flow to the extremities.
-
Taxotere is a chemotherapy medication commonly used for treating various types of cancer, including breast, lung, and prostate cancer. One significant issue linked to Taxotere is permanent hair loss, also known as alopecia, which can have a lasting emotional impact on patients. Other common side effects include fatigue, nausea, neuropathy, and a weakened immune system, making patients more susceptible to infections. Taxotere may also cause fluid retention, leading to swelling in the limbs or abdomen.
-
Testosterone medications, while beneficial for treating specific conditions like low testosterone levels, have been associated with various dangerous side effects. Known issues include an increased risk of cardiovascular events such as heart attacks and strokes, particularly in older individuals or those with pre-existing heart conditions.
-
The FDA has issued warnings about an increased risk of cardiovascular-related death linked to Uloric use compared to alternative gout treatments like allopurinol. Other potential side effects include liver function abnormalities, nausea, and skin rashes.
-
Varubi is meant to prevent nausea and vomiting caused by chemotherapy, but the drug has been linked to several safety concerns. This medication can cause serious allergic reactions, including anaphylaxis, which can occur during or shortly after administration. Varubi may also cause hypersensitivity reactions, with symptoms such as flushing, swelling, and difficulty breathing.
-
Viberzi, a medication used to treat irritable bowel syndrome with diarrhea (IBS-D), is now known to increase the risk of pancreatitis, particularly in patients without a gallbladder. Some patients have also reported experiencing severe abdominal pain and constipation while taking Viberzi.
-
Xarelto, a widely prescribed anticoagulant, is considered a dangerous drug due to its associated risk of severe bleeding. Unlike some older blood thinners, Xarelto does not have a readily available antidote to reverse its effects in emergency situations, making uncontrollable bleeding a significant concern. Patients taking Xarelto may also experience side effects such as gastrointestinal bleeding, stroke, and increased risk of blood clots if the medication is abruptly stopped.
