Moxifloxacin Tablet dosage

Take this medicine only as directed by your doctor. Do not take more of it, more often, or for longer than ordered. Swallow the tablet whole with a glass of water. Do not split, crush, or chew it. This medicine may be taken with or without food. Take this medicine at the same time each day.

Drink plenty of fluids while taking this medicine to help prevent some unwanted effects. If you take antacids containing aluminum or magnesium, iron supplements, multivitamins, didanosine, sucralfate, or zinc, do not take them at the same time as this medicine. Take these products at least 4 hours before or 8 hours after moxifloxacin, as they can keep it from working properly.

  • Moxifloxacin passes into breast milk. Talk to your doctor before using it while breastfeeding, as the benefits should be weighed against the risks to the baby.
  • Tell your doctor if you have kidney disease. Use with caution, as it may make side effects worse, and a dose adjustment may be needed. Kidney problems can also increase the risk of tendon problems.
  • Tell your doctor if you have liver disease, including cirrhosis. Use with caution. People with severe liver problems should avoid moxifloxacin or use it carefully, as it may worsen liver function.
  • Discuss with your healthcare professional the use of this medicine with alcohol.

  • Taking moxifloxacin raises the risk of tendon swelling (tendinitis) or a tendon tearing (rupture) during treatment or for up to several months afterward. The risk is highest in people over 60, those taking steroids, and those with kidney, heart, or lung transplants. Stop taking it and get help if you have tendon pain, swelling, or a snap or pop in a tendon area.
  • Moxifloxacin may cause nerve damage that may not go away even after you stop taking it. Stop the medicine and call your doctor if you have numbness, tingling, pain, burning, or weakness in your arms or legs.
  • Moxifloxacin may affect your brain or nervous system and cause serious side effects, even after the first dose. Stop the medicine and call your doctor if you have seizures, tremors, dizziness, hallucinations, mood changes, or thoughts of hurting yourself.
  • Moxifloxacin can worsen muscle weakness in people with myasthenia gravis and cause severe trouble breathing or death. Tell your doctor if you have this condition; it should not be used in people with it.
  • Moxifloxacin may cause serious diarrhea that can happen 2 months or more after you stop taking it. Do not take any diarrhea medicine without checking with your doctor first, as it may make things worse.
  • Moxifloxacin may increase your risk of an aortic aneurysm (a bulge in the wall of the body's largest artery).
  • Moxifloxacin should not be given to children younger than 18 years old, as it may cause problems with bones, joints, and the tissues around joints.
