The Texas House of Representatives has passed House Bill 25, permitting the over-the-counter sale of ivermectin, a medication that has been used for decades to treat parasitic illnesses. The bill passed Wednesday after almost three hours of discussion, on an 87-47 vote and one member who was present but not voting. If the bill passes the Senate, Texans would be able to buy ivermectin from pharmacists directly, as with other drugs such as Sudafed.Ivermectin, which was first discovered in the 1970s by Japanese microbiologist Satoshi Ōmura, has been a reliable cure for parasitic diseases like river blindness, scabies, lice, and strongyloidiasis. Its impact on global health earned Ōmura and collaborator William Campbell the 2015 Nobel Prize in Physiology or Medicine. The medication targets parasites by paralyzing and destroying them and disrupting their nerve and muscle functions.Despite its long-standing medical credibility, ivermectin became a contentious topic during the COVID-19 pandemic. Early laboratory studies suggested antiviral activity, prompting some to tout it as a COVID-19 treatment. Subsequent research, however, failed to show meaningful benefits for patients, and the U.S. Food and Drug Administration (FDA) has repeatedly emphasized that ivermectin is not authorized or approved to treat COVID-19. The FDA warns that abuse, especially with the veterinary form, can result in serious side effects such as seizures and coma.Rep. Joanne Shofner, a Nacogdoches Republican, wrote the bill, which has been identified as a priority for Governor Greg Abbott and House Speaker Dustin Burrows during the Legislature's second special session. Texas would join Arkansas, Idaho, Louisiana, and Tennessee as the fifth state to allow the sale of ivermectin without a prescription. Supporters point to "medical freedom" as a driving factor, saying patients deserve the ability to use treatments they think can help them, especially when vaccines or conventional therapy are rejected or considered inadequate.The passage of the bill is part of a larger movement of alternative medicine activists, fueled by social media sites that have promoted ivermectin for a host of off-label applications, from COVID-19 to cancer care.Why Is Ivermectin So Popular?Though the FDA-approved applications of ivermectin still only include parasitic diseases, it persists in showing up in alternative medicine forums. It turned into an icon of skepticism surrounding traditional medicine in the time of the pandemic, spurring demand long after vaccines had been found. In the present day, ivermectin is being researched for use in cancer, though evidence is currently narrow and inconclusive.During the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting, preliminary trials testing ivermectin combined with immunotherapy in metastatic triple-negative breast cancer were inconclusive: six of eight patients had disease progression, one showed partial response, and one had stable disease. Oncologists warn that promising laboratory results do not yet constitute clinican evidence for ivermectin in fighting cancer.What Are The Safety and Regulatory Concerns of Ivermectin Drug?The FDA emphasizes that ivermectin is safe when taken as prescribed for parasitic diseases, but inappropriately or in error, it can be hazardous. Veterinary products, usually in greatly higher concentrations, are quite hazardous to humans. Opponents caution that the sale of ivermectin over the counter may lead to self-medication, with resulting adverse events.Further, public health practitioners observe that although OTC access would be attractive to individuals who desire control of medical choices, it would complicate pharmacist counseling and regulatory control. Patients would not necessarily know proper dosing, interactions with other drugs, or the hazard of off-label use.The Texas debate brings attention to persistent tensions between patient autonomy and medical authority. Supporters of OTC access posit that adults must be capable of making intelligent decisions, pointing to past safety in parasitic disease treatment. Opponents suggest wider availability would worsen misinformation about COVID-19 and cancer claims.Social media has raised the level of interest in ivermectin, frequently citing cherry-picked studies or anecdotal experience as proof of efficacy. This pattern reflects a larger challenge for public health: the tension between patient autonomy and evidence-based recommendations.House Bill 25 now heads to the Texas Senate, where it will be determined. If passed, Texans could soon have simpler access to a drug with a complicated past adulated for its Nobel Prize-winning use as an anti-parasitic but contested for its unproven uses in viral infections and cancer.Experts note that although ivermectin does have valid medical applications, it is not a panacea. Those looking to use it for off-label purposes should see qualified healthcare professionals in an effort to reduce risk.Texas' possible shift towards over-the-counter sales of ivermectin points to a wider cultural and medical discussion: the interplay of individual choice, scientific evidence, and public safety. As ivermectin is an important agent against parasitic disease, its greater availability sparks concerns about prudent use, public health education, and the place of evidence in shaping medical practice.This battle is hardly over, but Texans and Americans generally are paying close attention as politicians work out the balance between independence, control, and science.
