Levofloxacin, while effective against sinus infections, carries potential side effects. Understanding these risks helps you make informed decisions with your doctor.
Common side effects include nausea, diarrhea, and headache. These are usually mild and resolve without intervention. However, more serious, though less frequent, side effects require immediate medical attention.
| Gastrointestinal | Severe diarrhea (potentially C. difficile infection), vomiting, abdominal pain | Contact your doctor immediately. This could indicate a serious complication. |
| Nervous System | Dizziness, lightheadedness, seizures, confusion, hallucinations | Seek immediate medical assistance. These symptoms require prompt evaluation and treatment. |
| Musculoskeletal | Tendinitis, tendon rupture (especially Achilles tendon), muscle pain | Stop taking Levofloxacin and contact your physician. Rest and avoid strenuous activity. |
| Allergic Reactions | Rash, itching, swelling, difficulty breathing | Stop taking Levofloxacin immediately and seek emergency medical care. This could be life-threatening. |
| Other | Increased risk of aortic aneurysm or dissection, prolonged QT interval (heart rhythm disturbance) | Discuss your medical history, especially heart conditions, with your doctor before starting Levofloxacin. Regular monitoring may be necessary. |
This information isn’t exhaustive, and individual reactions vary. Always discuss potential risks and benefits with your healthcare provider before starting any medication. They can assess your specific health status and determine the best course of treatment for your sinus infection.
