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.

Allergy: Cloxacillin is a type of penicillin and therefore should not be used by anyone with a serious penicillin allergy. People who have allergies in general should watch carefully for any reaction to cloxacillin when starting a new prescription.

Other infections: Treatment with any antibiotic may allow normal fungus or types of bacteria not killed by the antibiotic to overgrow, causing unwanted infections such as yeast infections. Contact your doctor as soon as possible if you notice symptoms of a new infection.

Stomach problems: People taking this medication may develop diarrhea caused by an infection with the bacteria C. difficile. If you have loose, watery and bloody bowel movements, with or without fever or stomach cramps after taking cloxacillin, get medical attention as soon as possible. Diarrhea caused by C. difficile infection can lead to serious health problems if it is not properly treated.

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: This medication passes into breast milk. If you are a breast-feeding mother and are taking cloxacillin, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
