What Is Metronidazole 500 Mg Used For

Metronidazole 500 mg is an antibiotic used to treat a variety of infections caused by certain bacteria and parasites. It is commonly prescribed for:

  • Bacterial vaginosis (an infection in women caused by harmful vaginal bacteria)[2][4][5]
  • Trichomoniasis (a sexually transmitted infection)[1][2][3]
  • Amebiasis (intestinal or liver infection caused by parasites)[1][2][6]
  • Giardiasis (parasitic intestinal infection)[1]
  • Pelvic inflammatory disease[4][7]
  • Gum and dental infections (including dental abscesses and gum disease)[4][7]
  • Skin infections and rosacea (topical forms)[1][7]
  • Infections in the abdomen, heart, bones, joints, central nervous system, and respiratory tract caused by anaerobic bacteria (such as Bacteroides and Clostridium species)[1][2][3][5]
  • Bloodstream (septicemia) and gynecological infections[2][3][5]
  • Prevention of infections after certain surgeries, especially involving the colon or reproductive organs[1][3]

Metronidazole is taken by mouth, usually as a tablet, but may also be given as a capsule, liquid, suppository, or injection depending on the infection and patient need[5][7]. It works by stopping the growth of sensitive bacteria and parasites[5].

It is important to complete the full prescribed course, even if symptoms improve before finishing the medication[8]. Avoid alcohol during treatment and for a few days after, as mixing the two can cause a serious reaction[2][7].
