Final answer:
The incorrect statement about Gilenya is that first dose observation does not need to be repeated if a patient misses 2 weeks of treatment. In fact, this observation must be repeated to ensure safety.
Step-by-step explanation:
The statement that is incorrect regarding Gilenya (fingolimod) is 'It isn't necessary to repeat first dose observation if a patient has missed 2 weeks of Gilenya.' On the contrary, if a patient miss taking Gilenya for 2 weeks or more, they should undergo the entire first dose observation process again. This includes monitoring of heart rate, blood pressure (BP), and an EKG for 6 hours. Additionally, due to the risk of macular edema, it is recommended that patients have their eyes examined before starting treatment and again 3-4 months after initiating treatment. Patients should also be educated on the symptoms of Progressive Multifocal Leukoencephalopathy (PML) prior to initiating therapy, as it is a serious condition that can occur in those taking Gilenya.
