This medication is given by injection into a vein as directed by your doctor, usually every 6 hours. It should be injected slowly over at least 30 minutes. The dosage is based on your medical condition, age, weight, and response to treatment. If you are giving this medication to yourself at home, learn all preparation and usage instructions from your health care professional.
