Ready-to-use combination containing two molecules in a fixed ratio formulation providing:

  • Rapid onset
  • Flexible dosage
  • IM or IV injection for dogs
  • IM injection for cats
  • Tiletamine HCL - a dissociative agent that produces profound analgesia plus deep surgical anesthesia in combination with zolazepam.
  • Zolazepam - a non-phenothiazine diazepinone molecule that produces tranquilization and, together with tiletamine HCL, adequate muscle relaxation.


Dose-dependent duration and depth of dissociative anesthesia


Suitable for common procedures requiring anesthesia and analgesia




Important Safety Information:
ZoletilTM for Injection (tiletamine and zolazepam for injection) should not be used : 1) in dogs and cats with severe cardiac or pulmonary dysfunction, or pancreatic disease; 2) at any stage of pregnancy or for Cesarean section; 3) in cats suffering from renal insufficiency; 4) with phenothiazine-derivative drugs as the combination produces respiratory and myocardial depression, hypotension, and hypothermia. Pulmonary edema has been reported in cats. Respiratory depression may occur following administration of high doses. Copious salivation that may occur during anesthesia can be controlled by concurrent administration of atropine sulfate. Reduce dosage in geriatric dogs and cats. Patients should be continuously monitored. For the full prescribing information download here or call 1-800-338-3659 or download here.
