Metronidazole can cause several side effects, though not everyone experiences them. Common side effects include nausea, vomiting, and diarrhea. These are usually mild and temporary. A metallic taste in your mouth is another frequent side effect.
Less common but more serious side effects include dizziness, headache, and seizures. If you experience any of these, contact your doctor immediately. A severe allergic reaction, characterized by difficulty breathing or swelling of your face, lips, tongue, or throat, requires immediate medical attention.
Dark urine is a possible side effect, indicating your body is processing the medication. However, unusual changes in your urine color should be reported to your doctor. Similarly, observe any changes in your vision or hearing.
While rare, blood disorders are a potential complication. Monitor yourself for unusual bruising or bleeding. Numbness or tingling in your extremities should also be reported.
Remember to inform your doctor about all medications you are taking, including over-the-counter drugs and herbal supplements, as interactions can occur. Follow your doctor’s instructions carefully regarding dosage and duration of treatment. Before starting any new medication, consult your physician.
