Before starting treatment with moxifloxacin, inform your healthcare provider about any existing medical conditions, allergies, or other medications you are taking. This includes prescription drugs, over-the-counter medications, and dietary supplements, as they may interact with moxifloxacin.
Specifically, discuss any history of:
- Allergies to moxifloxacin or similar antibiotics
- Tendon problems or tendon disorders
- Liver or kidney problems
- Heart rhythm disorders or a family history of such disorders
- High blood pressure
- Circulation problems
- Low potassium or magnesium levels in the blood
- Myasthenia gravis (a neuromuscular disorder)
- Diabetes
- Anemia
There is an increased risk of fluoroquinolone-associated tendinitis or tendon rupture with moxifloxacin. It can occur during therapy months later, after completing therapy. There is an increased risk in individuals over 60 years old, patients taking corticosteroids, transplant patients, rheumatoid arthritis patients, patients in renal failure, and during strenuous exercise.
Moxifloxacin also can increase your risk of central nervous system reactions (CNS). These reactions include seizures, increased intracranial pressure, hallucinations, confusion, depression, paranoia, and nightmares.
Moxifloxacin can cause photosensitivity (sensitivity to the sun). It is best to avoid excessive exposure to the sun during treatment.
If you are pregnant, planning to become pregnant, or breastfeeding, consult your healthcare provider before using moxifloxacin to assess potential risks and benefits.
