Pemetinib (pemetinib) usage warning: these groups should use with caution

Pemetinib (Pemetinib), this innovative drug has shown significant efficacy in the treatment of adult cholangiocarcinoma withFGFR2 rearrangement and myeloid/lymphoid tumors with FGFR1 rearrangement. However, each drug has its own specific scope of use and precautions, and pemetinib is no exception. Particularly for certain groups of people, this drug needs to be used with extreme caution.

First of all, patients who are allergic to pemetinib or any of its ingredients are strictly prohibited from using this drug. Allergic reactions may include skin rash, shortness of breath, swelling, etc. In severe cases, they may even cause anaphylactic shock, which is life-threatening. Therefore, patients must report their allergy history to their doctor in detail before starting treatment.

Secondly, pemetinib may induce retinal pigment epithelial detachment (RPED), a side effect that affects vision. Symptoms may include blurred vision and moving dark shadows in front of the eyes. For this reason, all patients should undergo a comprehensive ophthalmological examination, specifically optical coherence tomography, before initiating pemetinib treatment to detect and evaluate the ocular condition promptly. Particular caution should be exercised when using pemetinib in patients with pre-existing visual impairment. The retinas of such patients tend to be more fragile and may be more sensitive to the side effects of medications. In this case, doctors need to consider the patient's overall health and the possible risks and benefits of treatment.

In addition, pregnant women, lactating women, and children should also consult a professional doctor before using pemetinib. There is currently insufficient data on the safety and effectiveness of this drug in these special populations, so extra caution is needed.

In general, although pemetinib has brought new treatment hope to many patients, it is still necessary to strictly follow medical instructions when using it, especially for those patients who belong to the cautious use group. Through comprehensive medical consultation and regular health examinations, the safety and effectiveness of treatment can be ensured, so that patients can get the maximum benefit from it.
