What dose of NyQuil to give a cat between 10-20 lbs
1 Answer
Published on March 3rd, 2015
NyQuil should NOT be given to cats because one of its active ingredients is acetominophen - a drug that can be toxic to cats. A single adult dose of Nyquil® syrup contains 1000 milligrams of acetaminophen, the equivalent of more than three Tylenol tablets. Considering that the the ingestion of one 325-mg Tylenol tablet by a cat results in severe toxicosis, and two tablets ingested within 24 hours is fatal, 1000-mg is an extremely toxic dose of acetominophen.
