What should I do if I have a nosebleed while taking trametinib?

If you develop nosebleeds after taking trametinib, you should first stop taking the drug and gently press your nostrils with your fingers while leaning forward. Using a cold compress, such as an ice pack or a cold wet washcloth, can help constrict blood vessels and reduce nosebleeds. Keep your nasal cavity moist by using saline drops. If nosebleeds persist or occur frequently, or are accompanied by other serious symptoms (such as dizziness, vomiting, etc.), you should seek medical advice immediately. Remain calm during handling and closely monitor the development of symptoms to ensure the patient's safety and comfort. At the same time, be sure to inform your doctor that you are taking trametinib so that the doctor can better assess your condition and provide appropriate treatment recommendations.
