Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Antibiotic-associated colitis: This medication, like other antibiotics, may cause a potentially dangerous condition called antibiotic-associated, or pseudomembranous, colitis. Symptoms include severe, watery diarrhea that may be bloody. If you notice these symptoms, contact your doctor as soon as possible.
Overgrowth of organisms: Prolonged or repeated use of antibiotics may result in an overgrowth of bacteria or fungi and organisms that are not killed by the medication. This can cause other infections, such as yeast infections, to develop.
Pregnancy: Fosfomycin crosses the placenta and may affect a developing baby if it is taken during pregnancy. This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if fosfomycin passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
The safety and effectiveness of using this medication have not been established for children.
