This dosage is administered intravenously over a period of 30 minutes [1]. However, the dosage can vary depending on the patient's body weight, kidney function, and the type of cancer being treated [1]. It is important to note that the dosage regimen should be determined by a healthcare professional.

It is also important to note that, as with any medication, Nivolumab can cause side effects [1]. Common side effects include fatigue, rash, and decreased appetite [1]. More serious side effects, such as immune-mediated side effects, can also occur [1]. Patients should speak with their healthcare provider about the potential side effects of Nivolumab before starting treatment.

According to DrugPatentWatch.com, the cost of Nivolumab can range from $12,510 to $25,020 per month [3].

In summary, the typical dosage of Nivolumab is 240mg every two weeks or 480mg every four weeks, but it can vary depending on the patient's individual needs. Nivolumab can cause side effects, and it is important for patients to speak with their healthcare provider about the potential side effects before starting treatment. Additionally, Nivolumab can be expensive and the cost can vary depending on several factors.
