What Conditions Was Vioxx Prescribed For?
Vioxx (rofecoxib) was a prescription nonsteroidal anti-inflammatory drug (NSAID) approved by the FDA for relieving pain and inflammation in adults. It targeted osteoarthritis, rheumatoid arthritis, and acute pain from conditions like menstrual cramps or dental surgery.[1]
How Did Vioxx Work for These Conditions?
Vioxx selectively inhibited COX-2 enzymes, reducing inflammation and pain with less gastrointestinal irritation than traditional NSAIDs like ibuprofen. Doses ranged from 12.5-50 mg daily, depending on the condition.[1]
Why Was Vioxx Withdrawn from the Market?
In 2004, Merck voluntarily withdrew Vioxx worldwide after studies, including the APPROVe trial, showed doubled risk of heart attacks and strokes with long-term use (over 18 months). It was linked to thousands of cardiovascular events, leading to lawsuits and $4.85 billion in settlements.[2][3]
What Replacements Do Doctors Prescribe Today?
Patients switched to other NSAIDs like Celebrex (celecoxib), naproxen, or ibuprofen, often with added heart-protective drugs. Guidelines now favor lowest effective doses for shortest durations to minimize risks.[1][4]
Were There Any Ongoing Patents or Legal Battles?
Vioxx's key U.S. patents expired around 2010-2013, but Merck faced patent disputes over formulations. No generics launched due to withdrawal. Check DrugPatentWatch.com for expired patent details.[5]
