Why is this medication prescribed?
Infigratinib is a medication that belongs to a class of drugs known as fibroblast growth factor receptor (FGFR) inhibitors. It is prescribed for the treatment of a specific type of cancer called locally advanced or metastatic urothelial carcinoma (UC) that has specific genetic alterations.
Infigratinib is specifically used in patients with UC who have genetic alterations in the FGFR2 or FGFR3 genes and who have previously received chemotherapy or are ineligible for cisplatin-based chemotherapy. These genetic alterations lead to overactivation of the FGFR pathway, which plays a role in the growth and spread of cancer cells.
By inhibiting the FGFR pathway, infigratinib helps to slow down or stop the growth of cancer cells and may shrink tumors in patients with UC. It is typically used when other treatment options have been ineffective or are not suitable for the individual patient.
How should this medicine be used?
Infigratinib is available in the form of oral capsules. The recommended dosage and usage instructions may vary depending on the specific prescribing information and the patient’s individual circumstances. Therefore, it is important to follow the instructions provided by the prescribing healthcare professional or the medication guide.
Typically, infigratinib is taken orally once a day, with or without food. The capsules should be swallowed whole with a glass of water and should not be crushed, chewed, or opened.
It’s essential to adhere to the prescribed dosage and schedule without altering it unless specifically instructed by the healthcare provider. Taking infigratinib consistently at the same time each day helps maintain a steady level of the medication in the body, which can optimize its effectiveness.
If a dose of infigratinib is missed, the patient should consult their healthcare provider for guidance on what to do. It is generally recommended not to take an additional dose to make up for the missed one unless advised by a healthcare professional.
It’s important to attend regular follow-up appointments with the healthcare provider to monitor the response to treatment, manage any potential side effects, and make any necessary dosage adjustments.
Other uses for this medicine
Infigratinib is primarily used for the treatment of locally advanced or metastatic urothelial carcinoma (UC) with specific genetic alterations. However, it’s important to note that medications may sometimes be prescribed off-label, meaning they may be used for conditions or purposes not specifically approved by regulatory authorities. The off-label use of infigratinib would depend on the healthcare provider’s assessment and clinical judgment.
