Avelox (Moxifloxacin HCl)
Avelox is an antibiotic used to treat certain bacterial infections of the sinuses, respiratory (lung) tract, skin, and abdomen.
Avelox can cause tendon problems (such as tendon rupture or swelling). Your risk can increase if you are over 60 years; are taking corticosteroids (such as prednisone); have had a kidney, heart, or lung transplant; engage in physical activity or exercise; have kidney failure; or have past tendon problems (such as rheumatoid arthritis [a type of arthritis that involves inflammation of the joints]). Tell your doctor right away if you experience pain, swelling, tears, or inflammation of tendons in the back of your ankle (Achilles), shoulder, hand, or other tendon sites. Also, tell your doctor right away if you hear or feel a snap or pop in a tendon area, bruise right after an injury in a tendon area, or are unable to move the affected area or bear weight.
Avelox can cause worsening of myasthenia gravis (a disease characterized by long-lasting fatigue and muscle weakness) symptoms. Tell your doctor right away if you develop muscle weakness or breathing problems.
Serious or severe allergic reactions that may result in death if not immediately treated can occur while you are taking Avelox. Your doctor will not prescribe Avelox if you are allergic to it, any of its ingredients, or similar antibiotics (such as levofloxacin or ciprofloxacin). Tell your doctor right away if you experience a severe rash or difficulty breathing.
Do not drive, operate machinery, or engage in other activities that require mental alertness or coordination until you know how Avelox affects you. Tell your doctor right away if you experience dizziness, lightheadedness, pain, burning, tingling, numbness, weakness, or seizures.
Avelox can cause diarrhea or colitis (inflammation of the colon). This can occur even a couple of months after receiving the last dose of Avelox. Tell your doctor right away if you have diarrhea or colitis.
Use Avelox as prescribed by your doctor for the full course of treatment, even if symptoms improve earlier. Do not skip doses. Skipping doses or not completing the full course of Avelox can decrease its effectiveness and can lead to the growth of bacteria that are resistant to the effects of Avelox.
