Pharmacist tips for Poteligeo (mogamulizumab)
- Mark the dates of your infusions on your calendar or use an app on your phone to keep track of your appointments. It’s important to keep up with your appointments because Poteligeo (mogamulizumab) should be given within 2 days of the scheduled dose. This timing makes sure the medication works consistently in your body. If you miss a dose, you should notify your care team so that you can get the next dose as soon as possible.
- Each Poteligeo (mogamulizumab) infusion takes at least 60 minutes. But you can expect to be at the infusion center longer since it takes time for the pharmacy to prepare your dose. Please plan accordingly. Make sure you dress comfortably, bring water and food, and have something to help you pass the time, such as a book or music.
- Your care team will give you premedications, such as acetaminophen (Tylenol) and diphenhydramine (Benadryl), to take before your first dose of Poteligeo (mogamulizumab). These medications might help lower the risk of an infusion-related reaction, which can be very serious. Tell your care team if you have any chills, shaking, or shortness of breath; these can be signs of an infusion reaction.
- Check your temperature regularly, such as once a day, when you’re receiving Poteligeo (mogamulizumab) treatment. Call your care team immediately if your temperature is 100.4 degrees Fahrenheit or higher; this means you have a fever. It’s important to tell your care team if you’re sick. Sometimes, a fever might be the only sign that you’re sick.
- Pay close attention to your skin and speak with your oncologist if you notice any unusual changes. Poteligeo (mogamulizumab) can cause serious skin rashes. Changes in your skin could also be a sign that your cancer isn’t improving.
- Nausea and vomiting aren’t common side effects of Poteligeo (mogamulizumab). But call your care team if you’re having these side effects. Your oncologist might prescribe medications such as ondansetron (Zofran) or prochlorperazine to help you manage nausea.
- Talk with your oncologist if you’re pregnant or planning to become pregnant before you start treatment with Poteligeo (mogamulizumab). If you’re able to become pregnant, use effective birth control while you’re taking this medication and for 3 months after your last dose. Poteligeo (mogamulizumab) can cause harm to unborn babies.

Poteligeo (mogamulizumab) can cause serious immune problems. The medication can cause your immune system to become too active.

Symptoms of autoimmune problems depend on which organ is affected. They can include pain, weakness, shortness of breath, cough, low blood pressure, yellowing of the skin or eyes, or less urine, among others.

Tell your oncologist whether you’ve taken Poteligeo (mogamulizumab) in the past if you’re about to get a stem cell transplant. This helps your oncologist know your risks so that they monitor you more frequently or possibly adjust the timing of your transplant.
