Your height and weight are important factors your healthcare provider will take into consideration when determining an appropriate carmustine dosage. He or she will also carefully monitor your blood cell counts, as this drug can lower them significantly. Carmustine is an intravenous injection that is given no more often than every six weeks.
An Introduction to Your Dosage of CarmustineThe dosage of carmustine (BiCNU®) your healthcare provider recommends will vary, depending on a number of factors, including:
- Your height and weight
- How you respond to and tolerate it
- Other medications you are taking.
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
Recommended Carmustine Dosing GuidelinesLike many chemotherapy medicines, carmustine dosing is based on body surface area, which is normally calculated using your height and weight. Doses based on body surface area are written as milligrams per meter squared (mg per m2).
The initial recommended dosage of carmustine, when used alone, is usually 150 to 200 mg per m2 every six weeks. The dose may be given on one day as a single dose, or divided up as 75 to 100 mg per m2 on two consecutive days. People who are receiving other chemotherapy medicines may need lower doses.
Carmustine can cause a significant decrease in blood cells. Your healthcare provider will monitor your blood cell counts weekly after each dose and adjust your next dosage based on how low your blood cell counts drop.
Carmustine is given no more often than every six weeks, as it usually takes blood cell counts about that long to return to normal. However, your healthcare provider may recommend a longer break in treatment if your blood cell counts remain too low.
