Dysentery refers to furazolidone, which is generally not used in enemas. The drug belongs to the nitrofuran class of antimicrobials and is mainly used for the treatment of infections of gram-positive as well as negative bacteria, including Escherichia coli, Streptococcus aureus, Streptococcus pyogenes, Campylobacter spp., Shigella spp. and difficult-to-eliminate Helicobacter pylori infections, whose mechanism of action is to interfere with bacterial oxidation reductase enzymes, thus blocking the normal metabolism of bacteria. Furazolidone is generally administered orally and does not act via enema. Only 5% is absorbed orally, but high drug concentrations can be maintained in the intestines. Some patients may experience adverse reactions such as nausea, diarrhea, dizziness, headache, vomiting, rash, asthma, hypoglycemia, and occasionally hemolytic anemia, jaundice, and polyneuritis when using furazolidone tablets, which are contraindicated for those who are allergic to the drug, nursing mothers, and pregnant women. It is recommended that patients under the guidance of a doctor, strictly follow the instructions of the doctor to use the drug, do not blindly use the drug or unauthorized changes in the dose of the drug, so as not to cause adverse effects on the body, triggering the emergence of other diseases.
