Etopophos comes as a solution that is injected slowly into a vein by a healthcare provider. The specific dosage and the number of treatment cycles you receive will depend on a number of things, such as your height and weight and how you respond to the medicine. After receiving Etopophos for a few days, you will have a break to allow your body to recover.
An Introduction to Dosing With EtopophosThe dose of Etopophos® (etoposide phosphate) your healthcare provider recommends will vary, depending on a number of factors, including:
- Your height and weight
- The type of cancer being treated
- How you respond to the medication
- Other medications you are taking
- Other medical conditions you may have.
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
Etopophos Dosage for Small Cell Lung CancerLike many chemotherapy medicines, Etopophos dosing is based on body surface area, which is normally calculated using your height and weight. Doses based on body surface area are expressed as milligrams per meters squared (mg per m2).
In addition, Etopophos contains a salt form of the medication etoposide (Toposar®). Doses of Etopophos are usually expressed as the desired etoposide dose, rather than the Etopophos dose. This means that a healthcare provider will normally write an order to give an Etopophos dose equivalent to a certain amount of etoposide. The pharmacist will then determine how much Etopophos should be given.
The usual dose for treating small cell lung cancer is highly individualized and can range from the equivalent to 35 mg per m2 of etoposide once a day for four days to a dose equivalent to 50 mg per m2 of etoposide once a day for five days. People with kidney or liver disease are normally given lower amounts.
After receiving Etopophos for four or five days, you will be given a break in treatment to allow your body to recover from any side effects. The treatment and break period make up a cycle of treatment. Treatment cycles are normally repeated every three to four weeks. Your healthcare provider will tell you how many treatment cycles you need.
