Why is this medication prescribed?
Mogamulizumab-kpkc injection is used to treat mycosis fungoides and Sézary syndrome, two types of cutaneous T-cell lymphoma ([CTCL], a group of cancers of the immune system that first appear as skin rashes), in adults whose disease has not improved, has gotten worse, or has come back after taking other medications. Mogamulizumab-kpkc injection is in a class of medications called monoclonal antibodies. It works by activating the immune system to attack cancer cells.
How should this medicine be used?
Mogamulizumab-kpkc injection comes as a solution (liquid) to be injected intravenously (into a vein) over at least 60 minutes by a doctor or nurse in a hospital or medical office. It is usually given once a week for the first four doses, and then once every other week for as long as your treatment continues. The length of treatment depends on how well your body responds to the medication and the side effects that you experience.
You may experience a serious or life-threatening reaction while you receive a dose of mogamulizumab-kpkc injection. These reactions are more common with the first dose of mogamulizumab-kpkc injection but may occur at any time during treatment. Your doctor may tell you to take certain medications before receiving your dose to prevent these reactions. Your doctor will monitor you carefully while you are receiving the medication. If you experience any of the following symptoms during or after your infusion, tell your doctor immediately: chills, shaking, nausea, vomiting, flushing, itching, rash, fast heartbeat, shortness of breath, coughing, wheezing, dizziness, feeling like passing out, tiredness, headache, or fever. If you experience any of these symptoms, your doctor will slow down or stop your infusion and treat the symptoms of the reaction. If your reaction is severe, your healthcare provider may decide not to give you any more infusions of mogamulizumab-kpkc.
