Taking Tarceva: A Guide to Dosage and Administration
Tarceva, also known as erlotinib, is a brand-name drug used for the treatment of certain types of non-small cell lung cancer (NSCLC) and pancreatic cancer in adults. The drug is intended for long-term treatment, and most people take it until their cancer worsens or they experience serious side effects.
The standard dosage recommendations for Tarceva are as follows:
- For NSCLC, the recommended dosage is 150 mg once per day, taken on an empty stomach, preferably at the same time each day, at least 1 hour before or 2 hours after food.
- For pancreatic cancer, the dosage is 100 mg once per day, following the same administration guidelines as for NSCLC.
It is essential to follow the dosage prescribed by your doctor. Never take more Tarceva than prescribed, and if you believe you've taken too much, contact your doctor right away or contact America's Poison Centers. If you miss a dose, consult your doctor or pharmacist to determine when to take your next dose.
Other factors that may affect the dosage of Tarceva include other medical conditions you have, other medications you are taking, and whether you smoke cigarettes. For instance, if you smoke cigarettes or are taking another medication that's a CYP3A4 inducer, such as Rimactane (rifampin) or Tegretol (carbamazepine), your doctor may recommend a higher dose of Tarceva. On the other hand, if you are taking certain medications called CYP3A4 inhibitors, such as ketoconazole, your doctor may recommend a lower dose.
Tarceva comes as an oral tablet and is available in three strengths: 25 mg, 100 mg, and 150 mg. If you have difficulty opening medication bottles, ask your pharmacist about using an easy-open container or tools to make it easier. If you have difficulty reading your prescription label, talk with your doctor or pharmacist about options like large print, braille, or smartphone-scannable labels.
Remember, always follow the dosage that your doctor prescribes for you. Never change your dosage without your doctor's recommendation. For more information about Tarceva, see additional articles on its side effects, details about lung cancer and pancreatic cancer, and the Tarceva prescribing information.
In the case of pancreatic cancer, Tarceva is often taken in combination with the drug Infugem (gemcitabine). For detailed information about these treatments, consult your healthcare provider.
Staying informed and following your doctor's advice is crucial when taking Tarceva. If you have any questions or concerns, do not hesitate to discuss them with your healthcare team.
- It's important to note that Tarceva is also approved for the treatment of certain cases of pancreatic cancer, which is a type of cancer that falls under the category of medical-conditions.
- While taking Tarceva, be aware that it's sometimes prescribed in combination with another drug, Anthrax, for instance (though this is not a typical combination), as that drug is used mainly to treat anthrax, not cancer.
- Maintaining good health and addressing any health-and-wellness concerns are key when dealing with cancer, including pancreascancer, considering the potentially serious nature of these medical-conditions.
