This clinical trial aims to find out if using 1 gram of Multiprofen-CC cream on the hands three times a day for 4 weeks can help reduce pain in adults with hand osteoarthritis, compared to a placebo (a cream with no active medicine). The research team will also look at how Multiprofen-CC affects hand function, opioid use, and how patients feel about their overall improvement. In addition, the research team will keep track of any side effects.
Participants will:
* Use both Multiprofen-CC and a placebo (a cream with no active medicine) during the study, in a random order.
* Be asked to apply 1 gram of cream to their hands three times a day for 2 weeks, following the manufacturer's instructions.
* Attend a visit before starting the study, after 2 weeks, and after 6 weeks.
* Report any symptoms they experience during the study.
