Purchasing this medication in Mexico: Because Voltaren gel is not controlled in Mexico, it may be purchased without a prescription. Because Voltaren is a prescription drug in the U.S., a valid prescription written by a licensed U.S. doctor will be required to bring the medicine into the United States.

That item, sold over the counter in Mexico, is only available by prescription in the US. It is called Volfenac Diclofenac Gel.
