How should I take Metronidazole 200mg Oral Suspension 100ml?

Dosing depends on the infection, age, body weight, liver function, and the exact concentration written on your prescription bottle.
Your doctor will choose the dose and number of days based on the infection being treated. Children usually need weight-based dosing, so never estimate a child’s dose from an adult prescription.
Do not increase the dose, repeat a course, or share this medicine with another person. Incorrect use may lead to treatment failure, side effects, or antibiotic resistance.
