What Is Flagyl Used For 

The Flagyl generic name is metronidazole; it belongs to the class of nitroimidazole antimicrobial that kills bacterias and parasites to relieve infections. This antibiotic is not intended for viral infections like colds and flu; if used when not needed, it may cause ineffectiveness on future infections. Flagyl uses are listed below: 

Metronidazole can be used in various bacterial and parasitic infections, such as vaginal, stomach, liver, skin, brain, joints, spinal cord, heart, lungs, or bloodstreams. This medication can also be used in a sexually transmitted disease called trichomoniasis caused by a parasite that gives off a foul-smelling vaginal discharge, painful urination, and genital itching. Flagyl works in these conditions by leading the organisms to death; metronidazole diffuses and interferes with their synthesis to lose helical DNA and strand breakage leading to cell death. 

Flagyl Dosing 

Before starting this medication, read the drug information on the medicine leaflet and inform your doctor of all other medicines you are taking to avoid drug interactions. The dose and length of the treatment vary per patient based on their medical condition, weight, and response to the medication. Flagyl 500 mg and 250 mg are immediate-released tablets taken orally without regard to food. Listed here are the usual prescription; if prescribed differently, follow how it is instructed to you: 

  • For bacterial infection, 500 mg four times a day is given for 7 to 10 days; some infections may need an extended treatment period, but the maximum dose should only be 4g per day. 
  • For amoebic infection, 500 mg or 750 mg thrice a day is given for 5 to 10 days. 
  • For trichomoniasis, it can be given as a single dose of 2mg or in divided doses of 1mg twice a day for one day, or 250 mg three times a day for 7 days. 

Flagyl will work best if the amount of drug in the body is consistent; take it regularly at an evenly spaced time at the same time of the day every day. If a dose is missed, take it as soon as remembered, but if it is almost the time for the following intake schedule, skipping the missed dose for double dosing is discouraged. Continue taking the entire prescription even if you feel better, for early stopping may cause the infection to return.

How to deal with Flagyl side effects 

This medication is quite hard to tolerate due to its side effects, but there are ways to lessen the burden. 

  • Stomach upset can be avoided if tablets are taken with a snack, meal, or even a glass of milk.
