Drug Interaction Report

Moxifloxacin and other medications in its class can cause tendinitis and tendon rupture, and the risk may be increased when combined with a steroid such as triamcinolone. Older adults over 60 years of age and those who have received a kidney, heart, and/or lung transplant may be particularly susceptible. Tendon rupture can occur during or up to several months after finishing moxifloxacin treatment and may require surgery or result in prolonged disability. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. Stop taking moxifloxacin and call your doctor immediately if you experience pain, swelling, or inflammation of a tendon area such as the back of the ankle, shoulder, biceps, hand, or thumb. You should also avoid exercise or use of the affected area until further instruction from your doctor. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moxifloxacin and magaldrate should not be taken orally at the same time. Products that contain magnesium, aluminum, calcium, iron, and/or other minerals may interfere with the absorption of moxifloxacin into the bloodstream and reduce its effectiveness. If possible, it may be best to avoid taking magaldrate while you are being treated with moxifloxacin. Otherwise, moxifloxacin should be taken 2 to 4 hours before or 4 to 6 hours after a magaldrate dose, moxifloxacin should be taken at least 2 hours before and not less than 6 hours after Suprep Bowel Prep (magnesium/potassium/sodium sulfates), or moxifloxacin and magaldrate should be taken as directed by your healthcare provider. Talk to your healthcare provider if you are unsure whether your medications contain something that could potentially interact or if you have questions on how to take this or other medications you are prescribed. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
