Probenecid has been tested in children 2 to 14 years of age for use together with antibiotics. It has not been shown to cause different side effects or problems than it does in adults. Studies on the effects of probenecid in patients with gout have been done only in adults. Gout is very rare in children.


Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults. There is no specific information comparing use of probenecid in the elderly with use in other age groups.
