What does tachyphylaxis mean?
A rapid decrease in response to a drug or other stimulus after initial exposure, due to the body's adaptation to the stimulus. This can occur with various substances, including medications, and can lead to a decrease in their effectiveness over time.
Example
"The patient's tachyphylaxis to the pain medication meant that it was no longer providing the same level of relief as it had initially."
