Tarceva (Erlotinib)

Do’s

• Tarceva is typically taken by mouth on an empty stomach, usually once daily, as directed by a healthcare provider.
• The dosage of Tarceva is based on the individual's medical condition, response to treatment, and other medications being taken.
• Take Tarceva regularly to obtain the most benefit from it. Taking it at the same time each day can help maintain a steady level of the drug in the body, thus enhancing its effectiveness.
• Medications that lower stomach acid, such as antacids and H2 blockers, may prevent erlotinib from working. Consult your healthcare provider on how to use these medications safely with Tarceva.

Don’ts

• Do not increase the dose or use the drug more often or for longer than prescribed, as this can increase the risk of serious side effects without improving the condition any faster.
• Women who are pregnant or may become pregnant should avoid handling this medication or breathing the dust from the tablets, as the drug can be absorbed through the skin and lungs and may harm an unborn baby.
• Grapefruit and grapefruit juice should be avoided while using Tarceva, as they can increase the chance of side effects with this medicine 
• Smoking should be avoided while using Tarceva, as it can make the medication less effective.
• Exposure to sunlight or tanning beds should be avoided, as erlotinib can cause skin rash, dryness, or other irritation. Protective clothing and sunscreen should be used when outdoors.
