Doctors' Answers to "Frequently Asked Questions" - Drug Dosage
IVIG [posted 1/7/99]
Answer: I have two patients and at first adjusted it by their levels until a pattern was established. But, found out that it usually is 3-4 weeks for most whichever way you do it. The weight is usually ideal, but check the levels.
Answer: B.I.D. means twice daily, and H.S. means the hour of sleep.
Answer: Drug doses vary depending on their volume of distribution. Some drugs
are only distributed to body organs and the blood stream. Consequently, their levels are
based on ideal or lean weight, and not the actual weight of the patient. Other drugs are
distributed to fat and the actual weight is used to figure the dosage. In general, a 100
pound adult would require less of a drug than a 200 pound adult.
