Metronidazole should not be combined with alcohol. Mixing metronidazole with alcohol can result in a disulfiram-like reaction. This can cause symptoms like accelerated heart rate, skin flushing, nausea and vomiting, or visual disturbances.
The dosage of Flagyl (metronidazole) depends on the patient's individual needs, including the type and severity of the infection being treated. For many infections, a standard dose is 500 mg, taken orally two to three times daily for 7 to 10 days. For certain infections, such as trichomoniasis, a single large dose may be prescribed.
Dosage adjustments may be recommended for individuals with reduced liver function or who are on dialysis. Certain dialysis methods can be more or less likely to impact metronidazole levels. Some infections require more aggressive treatment than others. Consult your healthcare provider to better understand the unique risks and benefits associated with your needs.
Common questions and answers about Flagyl (metronidazole):
Flagyl (metronidazole) usually starts working within a few days, though the exact timing depends on the infection being treated. Many patients begin to feel better within 48-72 hours, but it is essential to complete the entire course of medication to ensure the infection is fully eradicated.
Flagyl (metronidazole) can be taken with or without food, but taking it with food may help reduce stomach upset, a common side effect. Follow your healthcare provider’s recommendations and try to take it at evenly spaced intervals to maintain a consistent level of the medication in your bloodstream. Avoid alcohol while taking Flagyl, as it can cause severe nausea and vomiting when combined with this medication.
