Tarceva, also known by its generic name erlotinib, is a medication commonly prescribed for the treatment of non-small cell lung cancer and pancreatic cancer. It belongs to a class of drugs called tyrosine kinase inhibitors, which work by blocking the action of a protein called epidermal growth factor receptor (EGFR) that is involved in the growth and spread of cancer cells.

Tarceva is typically taken orally once a day, with or without food, as directed by your healthcare provider. It is important to follow the dosing schedule and instructions provided by your doctor to ensure the medication is effective and to minimize the risk of side effects.

Like all medications, Tarceva can cause side effects, which may include rash, diarrhea, nausea, vomiting, and fatigue. It is important to report any side effects to your healthcare provider so they can be properly managed. In some cases, your doctor may adjust your dose or recommend a different treatment option.

It is also important to inform your healthcare provider about any other medications, supplements, or herbal products you are taking, as they may interact with Tarceva and affect its effectiveness or increase the risk of side effects.

Overall, Tarceva has been shown to be an effective treatment option for certain types of cancer, but it is important to work closely with your healthcare provider to determine if it is the right choice for you and to monitor your progress while taking the medication. If you have any questions or concerns about Tarceva, do not hesitate to discuss them with your doctor.
