Doctors need to sign when writing a prescription. The signature on the prescription must be clear and must not be altered. If modifications are required, the doctor must sign the modification and indicate the date of modification. In order to prevent signature errors, some doctors will have their own personal seal. There are no specific regulations on the shape and size of the seal, but it is best not to be too large.
