Ricovir-EM is one of the generic drugs that has the same active ingredients as Truvada, but made by a different company. It is being used by people all over the world as a way to access PrEP when Truvada is not readily available or affordable. Although there have no effectiveness studies on Ricovir-EM or Tenvir-EM, they both contain the same ingredients as Truvada, and there has been no reason or hypothesis to suggest one is more effective than the other.
Hope this answers your doubts.
