In medical terms, PR stands for Per Rectum. This term is commonly used to describe the method of administering medication or taking a patient’s temperature through the rectum. It is often abbreviated as PR in medical documentation and prescriptions.
For example, a doctor might prescribe a suppository to be administered PR, meaning it should be inserted into the rectum. Similarly, when taking a patient’s temperature, a PR reading might be taken if an oral or axillary (under the arm) reading is not possible or accurate enough.
This method is particularly useful in certain situations, such as when a patient is unconscious, unable to swallow, or when a more accurate body temperature reading is required.
