Flagyl is an antibiotic and antiprotozoal medication used to treat various infections. Its generic name is Metronidazole. It deals with a large number of microorganisms that are present in the body.

The medication is also used to cure a sexually transmitted disease known as trichomoniasis, usually caused by a parasite. It is, however, not advised to use Flagyl to treat any condition before seeing the doctor for advice and prescription.

How Does Flagyl Work?

  • Break the DNA Strand: Flagyl breaks the DNA strand of the bacteria and protozoa, thus hindering its growth and normal functioning.
  • Reduces the DNA Helix: Apart from aiming at the infectious bacteria, Flagyl targets its helical structure, ensuring it is drastically reduced and its stability affected.
  • Broad Spectrum: Metronidazole ensures that the activities of both the aerobic and anaerobic bacteria are destroyed, and if not, they are affected and drastically reduced in their functions.
  • DNA Synthesis Inhibition: By affecting the broad spectrum, Flagly inhibits the action of bacterial DNA and prevents bacterial synthesis.
  • DNA interference: Flagyl targets the DNA bacteria and microorganisms interfering with the bacteria’s survival.

Precautions and Warnings of Flagyl

  • Alcohol Consumption: You should neither take alcohol nor medicine that has traces of propylene glycol while taking Metronidazole. Interaction can still occur three days after consuming Flagyl.
  • Pregnancy: Flagyl may harm the fetus and unborn babies. Pregnant women should not use Metronidazole to treat trichomoniasis while within the first trimester of pregnancy.
  • Blood Disorder: Flagyl also reduces the white blood cell count in the blood.
  • Historical Health Conditions: Those who have ever been diagnosed with severe conditions such as kidney disease, liver disease, heart rhythm disorder, nerve disorder, and fungal infections should inform their doctor and get advice on how to take Flagyl safely.
  • Breastfeeding: A lactating other should not breastfeed the baby within 24 hours of using Flagyl. The drugs may affect the feeding infant and can cause cases of candidiasis and diarrhea.

Side Effects Associated with Flagyl

  • Vaginal Itching or Discharge: Sometimes, patients who use Flagyl to treat trichomoniasis may experience itching or discharge from their private parts.
  • Painful and Difficult Urination: Patients who use Flagyl might also experience pain and difficulty in urination. Seek medical attention if you experience this side effect.
  • Confusion: A patient taking Flagyl might experience mental confusion at some point, but that is just a side effect of the drug.
  • Muscle Weakness: If you experience muscle weakness after using Flagyl, inform your doctor immediately.
