The recommended Vectibix dosage will depend on your weight, whether you develop serious reactions to the drug, and other factors. The usual dose is 6 mg per kg body weight given every 14 days. The medicine comes as a liquid and is given as an intravenous (IV) infusion by a healthcare provider.
An Introduction to Dosing With VectibixThe dose of Vectibix® (panitumumab) your healthcare provider recommends will vary, depending on:
- Your weight
- Side effects you experience.
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
Recommended Vectibix DosageThe standard dosage of Vectibix for the treatment of advanced colorectal cancer is 6 mg per kg body weight (about 2.7 mg per lb) every 14 days.
The medication will normally be stopped, at least temporarily, in people who experience serious or intolerable skin reactions. If the skin reaction improves within one month, Vectibix may be restarted at a lower dose -- usually 3 mg per kg body weight (about 1.4 mg per lb). This amount may be increased slowly to the standard dosage of 6 mg per kg if skin reactions do not recur.
