A drag-reducing additive comprises a dispersion polymer and a microemulsion. The dispersion polymer comprises a polymer and a saline solution, and the microemulsion comprises a solvent, a surfactant and an aqueous phase. The drag-reducing additive can be combined with an aqueous treatment fluid to form a drag-reducing composition. A method of using a drag-reducing composition, wherein the method comprises providing a drag-reducing additive comprising a dispersion polymer and microemulsion, forming the drag-reducing composition by combining the drag-reducing additive with an aqueous treatment fluid, and injecting the drag-reducing composition into a subterranean formation, a pipeline or a gathering line.
