# qiskit.circuit.Instruction.inverse¶

- Instruction.inverse()[source]¶
Invert this instruction.

If the instruction is composite (i.e. has a definition), then its definition will be recursively inverted.

Special instructions inheriting from Instruction can implement their own inverse (e.g. T and Tdg, Barrier, etc.)

- Returns
a fresh instruction for the inverse

- Return type
- Raises
**CircuitError**– if the instruction is not composite and an inverse has not been implemented for it.
