Flagyl Patient Tips
How it works
- Flagyl is a brand (trade) name for metronidazole.
- Metronidazole is an antibiotic that may be used in the treatment of anaerobic infections caused by bacteria or protozoa. Anaerobic means "living without air".
- Treats a wide range of infections such as those occurring in the abdomen, gastrointestinal tract, in the deeper layers of the skin, genitourinary area, in bones or joints, throughout the blood, in the central nervous system, heart and lower respiratory tract.
If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:
- A headache, nausea, diarrhea, an unpleasant metallic taste, peripheral neuropathy (nerve damage to fingers and toes), or a rash are common side effects. Rarely, seizures.
- Flagyl reacts with alcohol. Symptoms include abdominal cramps, nausea, vomiting, headaches, and flushing. Avoid alcohol while taking Flagyl.
Notes: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects.

- May be taken with or without food.
- Avoid alcohol while taking Flagyl, and for three days after you have finished your course of Flagyl.
- Take exactly as directed and for the duration intended.
- Only use when prescribed by a doctor to treat infections caused by susceptible bacteria as improper use increases the chance of resistant bacteria developing.
- Seek medical advice if numbness, pain, or sensitivity occurs in your fingers or toes, or if you notice any skin color changes in these areas.
Response and Effectiveness
Peak concentrations are reached within one to two hours after dosing; however, it may take up to 48 hours before infection-related symptoms start to abate.
