Why is this medication prescribed?

Gilotrif (generic name: afatinib) is a prescription medication primarily used in the treatment of certain types of advanced non-small cell lung cancer (NSCLC). It is specifically indicated for patients with metastatic NSCLC whose tumors have certain genetic mutations, such as those with epidermal growth factor receptor (EGFR) mutations.

EGFR mutations can drive the growth of cancer cells in some individuals with NSCLC. Gilotrif works by inhibiting the activity of EGFR and certain other proteins that play a role in the growth and spread of cancer cells. By blocking these proteins, Gilotrif helps to slow down or stop the growth of cancer cells, potentially leading to tumor shrinkage and improved outcomes for patients with NSCLC.

How should this medicine be used?

Here’s how Gilotrif is typically used:

• Dosage: The recommended dosage of Gilotrif is usually determined by a healthcare provider based on factors such as the patient’s overall health, the specific type and stage of cancer, and any other medications the patient may be taking.
• Administration: Gilotrif is usually taken orally once daily, with or without food. It’s important to swallow the tablets whole and not crush or chew them.
• Follow-up testing: Patients taking Gilotrif may need to undergo regular monitoring, including blood tests and imaging scans, to assess the response to treatment and monitor for any potential side effects.
• Adherence: It’s crucial for patients to take Gilotrif exactly as prescribed by their healthcare provider. Missing doses or taking more than prescribed can affect the effectiveness of the treatment.
• Side effects management: Like all medications, Gilotrif can cause side effects. It’s essential for patients to report any side effects to their healthcare provider promptly. Common side effects of Gilotrif may include diarrhea, skin rash, mouth sores, and decreased appetite, among others. Your healthcare provider may provide guidance on managing these side effects.
• Duration of treatment: The duration of Gilotrif treatment can vary depending on factors such as the response to treatment, disease progression, and tolerability. Patients should continue taking Gilotrif for as long as their healthcare provider recommends, even if they start to feel better.
• Discontinuation: It’s important not to stop taking Gilotrif without consulting a healthcare provider, even if side effects occur. Suddenly stopping the medication can lead to adverse effects and may not effectively control the cancer.

Patients should consult their healthcare provider for specific instructions on how to take Gilotrif and any other questions or concerns they may have about their treatment.
