Some tendon problems include pain, swelling, tears, and inflammation of tendons including the back of the ankle (Achilles), shoulder, hand, or other tendon sites.

Call your healthcare provider right away at the first sign of tendon pain, swelling, or inflammation. Also, get medical help 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.

    Noroxin can cause worsening of myasthenia gravis (a disease characterized by long-lasting fatigue and muscle weakness) symptoms. Call your healthcare provider right away if you develop worsening muscle weakness or breathing problems.

    More common side effects may include: dizziness, nausea, headache, stomach cramps.

    Less common side effects may include:

    Serious allergic reactions, with symptoms such as hives; rash; trouble breathing or swallowing; swelling of the face, lips, tongue, or throat; rapid heartbeat; fainting; or skin rash accompanied by fever and feeling unwell.

    Liver damage, with symptoms such dark colored urine, or yellowing of your skin or whites of your eyes.

    Changes in sensation and possible nerve damage in your arms, hands, legs, or feet, with symptoms such as pain, burning, tingling, numbness, or weakness in any of these areas of your body.

    Changes in the electrical activity of your heart, with symptoms such as fast or slow heartbeat, or fainting.

    Watery and bloody stools (with or without stomach cramps and fever), even as late as two or more months after having taken the last dose of Noroxin.

Also, talk to your healthcare provider about your complete medical history, especially if you have tendon, nerve, bone, kidney, or liver problems; myasthenia gravis; seizures; joint problems; low blood potassium levels; diabetes or problems with low blood sugar; or if you or anyone in your family has an irregular heartbeat, especially prolonged QT interval (very fast or abnormal heartbeats).

    Do not drive, operate machinery, or engage in other activities that require mental alertness or coordination until you know how Noroxin affects you.
