Flagyl and Alcohol
Avoid drinking alcohol or products containing propylene glycol during intake of Flagyl and at least 3 days after Flagyl therapy. Metronidazole is associated with disulfiram-like reactions to alcohol such as abdominal cramps, vomiting, nausea, headache, and flushing.
Consult a doctor to get the correct dosage of Flagyl as it will vary per patient. It is important to complete the full course of treatment even if the patient started feeling better in a few days of taking the medication as the symptoms may improve even before the infection is treated. The dose and duration of treatment will depend on the infection being treated and the severity of infection. Take a tablet of Flagyl by mouth, swallowed whole with a full glass of water or milk to prevent stomach upset. It may be taken during or just after a meal. Take a missed dose as soon as remembered but skip it if it’s almost time for the next dose. Do not double the dose to make up for the missed dose. Skipping doses will increase the risk of antibiotic resistant infection therefore it is best to strictly follow the dosing schedule.
The usual adult dose of Flagyl in treating bacterial infection is 800mg as an initial dose. The next dose of 400mg is taken after 8 hours and repeated every 8 hours.
To prevent bacterial infections after surgery, Flagyl should be taken 24 hours before the surgery. A dose of 400mg is taken every 8 hours. Children are given Flagyl tablets 1 to 2 hours before an operation.

- 2g of Flagyl as a single dose or in two divided doses as one-day treatment.
