How to Take

The treatment condition will determine the dosage of Metronidazole. For most infections, a typical dose is 500 mg taken twice a day for 7 to 10 days. However, always follow the instructions provided by your doctor.

You can take metronidazole with or without food. If it causes stomach upset, taking it with food may help.

• Swallow Whole: Take the tablet with a glass of water. Do not crush or chew the tablet.
• Missed Dose: If you miss a dose, take it as soon as you remember unless it is almost time for your next dose. Do not take two doses to make up for a missed dose.
• Complete the Course: Even if you start feeling better, it’s crucial to finish the entire course of treatment to guarantee the full clearance of the infection.

Always follow your doctor’s instructions regarding dosage and duration of treatment.
