Metronidazole tablets are not painkillers, but an anti-anaerobic antibiotic.
The drug has a killing effect on anaerobic microorganisms, and the metabolites generated when it is reduced in the human body also have an anti-anaerobic effect, inhibiting the synthesis of bacterial deoxyribonucleic acid, thus interfering with bacterial growth and reproduction, and ultimately leading to bacterial death.
Clinically the drug is used to treat acute wisdom tooth pericoronitis, pulpitis, facial folliculitis, acne, intestinal and extra-intestinal amebiasis, vaginal trichomoniasis, abdominal infections, and pelvic infections caused by anaerobic bacterial infections.
Adverse reactions such as nausea, vomiting, loss of appetite, and abdominal pain may occur during administration.
It is contraindicated in people with active central nervous system disorders and blood diseases; in people who are allergic to the components of the drug; in pregnant and lactating women.
The metabolites of the drug can make the urine dark red; the drug should be discontinued in the event of movement disorders or other central nervous system symptoms; alcohol should be abstained from during the use of the drug, and symptoms such as abdominal pain, vomiting, and headache may occur after drinking alcohol.
If you need to use the drug, you should go to the hospital to check and clarify the cause of the disease, and choose the drug to use under the guidance of the physician.
