Intravenous Flagyl, while effective against Clostridioides difficile (C. diff), carries potential side effects. Understanding these risks helps you and your doctor make informed decisions.
Gastrointestinal Issues
- Nausea and vomiting are common. Manage this with antiemetics as prescribed. Diarrhea, separate from C. diff, can occur. Report persistent or severe diarrhea to your doctor immediately. Abdominal pain or cramps are possible. Proper hydration often alleviates this.
Neurological Effects
- Headache is a relatively frequent side effect. Over-the-counter pain relievers might help, but consult your doctor. Dizziness or vertigo can occur. Avoid driving or operating machinery until these symptoms subside. In rare cases, seizures have been reported. This requires immediate medical attention.
Other Potential Side Effects
Metallic taste in the mouth: This usually resolves on its own. Changes in blood counts: Regular blood tests monitor this. Allergic reactions: Report any skin rashes, itching, or difficulty breathing immediately. Inflammatory effects: Your doctor will monitor for any unexpected inflammation.
Managing Risks
Open communication with your healthcare provider is key. Report any unusual symptoms promptly. Careful monitoring during and after treatment minimizes risks.
