Vancomycin: How to use, Side Effects, Dosage

What is Vancomycin?

Vancomycin belongs to the group of medications known as antibiotics. Vancomycin is an antibiotic used to treat infections. This form of vancomycin is used to treat a certain intestinal condition (colitis) caused by bacteria. This condition causes diarrhea and stomach/abdominal discomfort or pain. When vancomycin is taken by mouth, it stays in the intestines to stop the growth of certain bacteria that cause these symptoms. Antibiotics such as vancomycin injection will not work for colds, flu, or other viral infections. Taking or using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment. Vancomycin injection is used to treat infections in many different parts of the body.

How to use Vancomycin?

Vancomycin injection comes as a powder to be added to fluid and injected intravenously (into a vein). It is usually infused (injected slowly) over a period of at least 60 minutes once every 6 or 12 hours, but may be given every 8 hours in newborn babies. Take this medication by mouth as directed by your doctor, usually every 6 to 8 hours. Shake the bottle well before each dose. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.

The dosage is based on your medical condition and response to treatment. In children, the dosage is also based on weight.

If you are also taking certain bile acid-binding cholesterol medication (such as cholestyramine, colestipol), take it at least 3 to 4 hours after taking vancomycin. Taking them together will make vancomycin work less well. Ask your pharmacistif you have questions.

Dosage of Vancomycin

The usual oral dose for adults is 125 mg to 500 mg taken every 6 to 8 hours for 7 to 10 days.

The usual intravenous, (into a vein), or IV dose for adults is 500 mg given every 6 hours or 1g given every 12 hours. For IV injections, the dose of this medication will be administered by your doctor or health care professional. The length of treatment with IV vancomycin depends on the severity of the infection and the response to the medication.

For children, the oral form (given by mouth) is based on body weight and is given in 3 or 4 daily doses for 7 to 10 days. The IV form of vancomycin, also based on body weight, is given every 6 hours. The total daily dose should not be greater than 2,000 mg.
