How many boxes of pemetinib do I need to take every month?

Pemigatinib, also known as pemigatinib, is an FGFR inhibitor commonly used to treat patients with locally advanced or metastatic cholangiocarcinoma carrying FGFR2 fusions or rearrangements. According to the common recommended usage, the drug is usually taken in cycles: once a day, 13.5 mg each time, continuous taking for 14 days and then stopping for 7 days, and 21 days as a course of treatment. This "14days of taking medication+7days of stopping medication" is currently the most common dosing cycle, also known as the "intermittent dosing pattern."

According to the dosage of 13.5mg one tablet per day, the patient actually takes the medicine during a 21 day treatment course 14days, that is, 14tablets13.5mg specifications of pemetinib tablets are needed. The common packaging specifications on the market are 13.5mg Therefore, according to the standard usage of one course of treatment every 21 days, only 1 box of medicine is usually needed in one month (about 30 days).

It should be noted that due to individual differences, some patients may be adjusted to other dosages (such as 9mg or 4.5mg) or continuous medication rather than intermittent medication. In addition, during the actual treatment process, if the disease progresses rapidly or continuous clinical medication is required, the doctor may adjust to continuous daily administration instead of stopping the medication for 7 days, at which time the monthly dosage will increase to 30pieces or more may require 2 boxes or even 3 boxes. Therefore, patients should strictly follow the doctor's instructions to adjust the dosage and avoid changing the frequency of medication without authorization.
