Tinidazole is an antibiotic and antiprotozoal medication used to treat various infections. It’s commonly prescribed for bacterial vaginosis, trichomoniasis, giardiasis, and amebiasis—conditions caused by bacteria or parasites. Tinidazole works by damaging the DNA of microorganisms, effectively killing them and stopping the infection’s spread. It’s also used for infections in the brain, gastrointestinal tract, reproductive system, and skin. Available as oral tablets, it’s suitable for adults and children over three years old.
