Pharmaceutical & Bad Drugs Lawyer in Houston, TX

Houston personal injury lawyer, Charles J. Argento assists Texas residents with lawsuits and damage claims after a serious injury or death resulting from the use of a harmful drug they presumed was safe. All drugs we purchase are required by law to meet certain safety guidelines and standards for use. When these drugs fail to meet these standards and an injury results, you have the right to seek compensation for medical bills, lost wages and long-term care.

Defective or dangerous product injuries from drugs generally result from flaws (intentional or not) that arise during the testing, design, manufacture and distribution of a consumer drug.

While many Houston harmful drug lawyers may claim to take dangerous drug cases, few of them have the legal, technical and financial resources to effectively investigate the circumstances and identify all responsible parties down the chain of distribution.
