What is Prexan?
Prexan is a nonsteroidal anti-inflammatory drug (NSAID). It works by reducing hormones that cause inflammation and pain in the body.
Prexan is used to treat pain or inflammation caused by conditions such as arthritis, ankylosing spondylitis, tendinitis, bursitis, gout, or menstrual cramps. It can also be used to treat acute pain caused by other conditions not listed in this medication guide.
The delayed-release or extended-release tablets are slower-acting forms of Prexan that are used only for treating chronic conditions such as arthritis or ankylosing spondylitis. These forms will not work fast enough to treat acute pain.
*These forms are for children ages 2-11 years, with dosage based on weight. †Only for people 12 years or older
Since ibuprofen and Prexan are both NSAIDs, they have the same side effects. However, the risk of heart and blood pressure-related side effects is greater with Prexan.
