What is Vioxx, and what was it used for?
Vioxx is the brand name for rofecoxib, a pain-and-inflammation medicine in the Cox-2 inhibitor (COX-2) class. It was prescribed for conditions such as osteoarthritis, acute pain, and dysmenorrhea (painful menstrual periods).
Why was Vioxx pulled from the market?
Vioxx was withdrawn after evidence linked Cox-2 inhibitors to an increased risk of serious cardiovascular events (including heart attack and stroke). The drug’s safety profile changed once those risks became clearer, leading to the company pulling it and regulators later acting to restrict similar drugs in the same class.
Does Vioxx have an approved replacement now?
There is no current approved Vioxx product. Patients and clinicians typically use other pain options, which may include different NSAIDs (with different COX selectivity), acetaminophen, or non-drug approaches—chosen based on cardiovascular risk, gastrointestinal risk, and the specific pain condition.
What are COX-2 inhibitors, and how are they different from other NSAIDs?
COX-2 inhibitors like rofecoxib were designed to target the COX-2 enzyme more selectively than traditional NSAIDs. That selectivity was intended to reduce some gastrointestinal side effects common to older NSAIDs, but it also appeared to raise cardiovascular risk.
Was Vioxx still protected by patents, and where can I track exclusivity/patent history?

Are there any ongoing lawsuits or claims related to Vioxx?
Vioxx litigation became widespread after the drug’s withdrawal, with many claims focused on alleged failure to adequately warn about cardiovascular risks. Case outcomes vary by jurisdiction and individual circumstances.
