An implantable medical electrical lead is connectable to an electrical header of an implantable pulse generator. The lead includes a lead body, at least one electrode, a lead terminal, and a lead boot. The lead body extends from a proximal end to a distal end. The at least one electrode is disposed at the distal end of the lead body. The lead terminal is disposed at the proximal end of the lead body and configured to connect the lead to the electrical header. The lead boot is formed of an elastic polymer infused with at least one antibiotic drug. A portion of the lead boot is configured to bedisposed within the electrical header when the lead is connected to the electrical header.
