Are there any other precautions or warnings for this medication?
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.
Bacterial resistance: Misuse of an antibiotic such as vancomycin may lead to the growth of resistant bacteria that will not be killed by the antibiotic. If this happens, the antibiotic may not work for you in the future. Although you may begin to feel better when you first start taking vancomycin, you need to take all the medication exactly as directed by your doctor to finish ridding your body of the infection and to prevent resistant bacteria from taking hold. Do not take vancomycin or other antibiotics to treat a viral infection such as the common cold; antibiotics do not kill viruses, and using them to treat viral infections can lead to the growth of resistant bacteria.
Hearing loss: Vancomycin can cause hearing loss. People with a history of hearing loss should not take this medication if possible. If you experience any hearing loss, dizziness, or ringing ears while taking this medication, contact your doctor immediately.
Intestinal inflammation: People with conditions associated with inflammation of the intestines (e.g., Crohn's disease, ulcerative colitis) may be at higher risk for side effects when they take vancomycin capsules, especially if they also have impaired kidney function. Your doctor will monitor you closely for side effects.
Kidney function: Reduced kidney function or kidney disease may cause this medication to build up in the body, causing side effects. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Vancomycin can cause kidney damage. If you experience symptoms of reduced kidney function such as decreased urine production, swelling, fatigue, or abdominal pain, let your doctor know as soon as possible.
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 breast-feeding and are receiving IV vancomycin, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: Premature neonates and young infants may require regular blood tests to ensure that the child is receiving the most appropriate dose.
Seniors: Seniors may be more likely to experience side effects associated with vancomycin as a result of reduced kidney function. They may need a lower dose or be put on a less frequent dosing schedule.
