Flagyl, or metronidazole, can cause several side effects. Common ones include nausea, vomiting, and diarrhea. These usually are mild and resolve without treatment. However, if they persist or worsen, contact your doctor.
Less common, but still possible, side effects involve metallic taste in your mouth. This usually fades as the medication is stopped. Some individuals report headaches or dizziness. These are generally manageable with over-the-counter pain relievers or rest.
More Serious Side Effects
While rare, more serious side effects require immediate medical attention. These include seizures, severe abdominal pain, and difficulty breathing. Allergic reactions, such as skin rashes or swelling, are also possible and necessitate prompt medical help.
Interactions and Precautions
Flagyl interacts with certain medications, including alcohol. Avoid alcohol consumption during treatment and for at least 24 hours afterward. Inform your doctor about all medications and supplements you’re taking to prevent interactions. Pregnant or breastfeeding women should discuss Flagyl use with their physician.
