Erlotinib Dosage

Your dosage of erlotinib will depend on several factors, such as the type of cancer being treated and whether you are taking other medications. The standard dose is 100 mg a day for prostate cancer and 150 mg a day for non-small cell lung cancer. To keep an even level of medication in your body, take each dosage at the same time each day.

An Introduction to Your Dosage of Erlotinib

The dose of erlotinib (Tarceva®) your healthcare provider recommends will vary, depending on a number of factors, such as:
 
  • Why you are using the medication
  • How well you tolerate it
  • Other medical conditions you may have
  • 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.
 

Erlotinib Dosing for Pancreatic Cancer

The standard dose of erlotinib for the treatment of pancreatic cancer is 100 mg once a day. Treatment usually continues until a benefit is no longer seen or serious side effects occur.
 

Erlotinib Dosing for the Treatment of Lung Cancer

The standard dose of erlotinib for the treatment of advanced non-small cell lung cancer is 150 mg once a day. As with pancreatic cancer, treatment usually continues until a benefit is no longer seen or serious side effects occur.
 
Regardless of whether you are taking erlotinib for pancreatic cancer or lung cancer, people who experience certain potentially serious side effects, such as lung disease, severe diarrhea, and skin reactions, may need to stop taking the medicine or use a lower dose. If a dose reduction is necessary, erlotinib is generally reduced in 50-mg increments.
 
People who take certain other medications may also need lower or higher erlotinib doses (see Drug Interactions With Erlotinib). The maximum recommended amount is 450 mg daily.
 
Smoking may decrease erlotinib blood levels. Therefore, people who smoke may need higher doses. The maximum recommended erlotinib dosage in people who smoke is 300 mg a day.
