Enema to reduce fever is the absorption of drug components through the intestinal mucosa to play the role of drugs to help reduce fever, there are some people with fever, caused by bacterial and viral infections in the intestinal system, these people can be treated by enemas to help reduce fever. Enemas can help reduce fever by allowing the medication to act directly on the intestinal system to quickly kill the viruses and bacteria in the intestinal system, and the intestinal mucosa can quickly absorb the medication and allow the medication to enter the bloodstream, thus achieving a rapid reduction in fever. Since the drug enters the intestinal system directly without passing through the stomach, the damage to the stomach is relatively reduced, but some people have inflammation and ulcers in the intestinal system, so the use of enemas to reduce fever should be avoided to avoid aggravating the ulcerated surface of the intestine.
