Proleukin (aldesleukin) is an immunotherapy medication also known as cytokine therapy. It treats skin cancer and kidney cancer that has spread to other parts of the body. But it's not a first-choice option for these conditions because it can cause serious side effects. Typically, Proleukin (aldesleukin) is infused into the veins 3 times a day for 5 days, through 2 cycles. Proleukin (aldesleukin) must be given in a special facility with the staff and equipment needed to treat severe side effects, such as low blood pressure and heart problems.

Proleukin (aldesleukin) is a man-made form of an immune protein (cytokine) found naturally in your body called interleukin-2 (IL-2). This protein plays an important role in the immune system by activating white blood cells in the body to help fight against invaders, like cancer. By acting just like IL-2, Proleukin (aldesleukin) turns on your immune system to target and kill cancer cells.

Let your healthcare provider know if you're taking medications to lower your blood pressure because Proleukin (aldesleukin) can also lower blood pressure. Your provider will likely ask you to stop taking the blood pressure medications to prevent a serious interaction with Proleukin (aldesleukin).
Proleukin (aldesleukin) can put you at higher risk for developing an infection because it lowers your blood cell counts. Your provider will order blood work daily while you're receiving Proleukin (aldesleukin) to check your levels. Contact your provider if you develop a fever, which can be a sign of infection. It's important that your care team treat the infection early.
Proleukin (aldesleukin) raises your risk of serious infection.

To lower the risk of nausea and diarrhea while taking Proleukin (aldesleukin), consider eating foods that are part of the BRAT diet. These foods (e.g., applesauce, bananas, oatmeal) are easier on your stomach. Try to avoid foods that can worsen your symptoms, like greasy, spicy, or acidic foods.
It's important to take good care of your teeth and mouth while receiving Proleukin (aldesleukin) to prevent mouth sores. Consider using a soft bristle toothbrush and brushing your teeth 2 to 3 times a day.
Let your healthcare provider know if you develop mouth sores while receiving Proleukin (aldesleukin). They can recommend ways to ease your symptoms, such as rinsing your mouth with a baking soda and salt water rinse, or sucking on ice chips.
If you experience dry, itchy skin while receiving Proleukin (aldesleukin), you can use an mild, fragrance-free cream or lotion rehydrate your skin. Try to avoid scratching or breaking the skin as this might raise your risk of infection.
Proleukin (aldesleukin) might cause serious harm to an unborn baby. If you’re able to become pregnant, you should use birth control (e.g., birth control pills or condoms) while receiving Proleukin (aldesleukin).
If you need to get imaging with iodinated contrast material, let your provider know that you've received Proleukin (aldesleukin), especially if it has been less than a month since your last dose. You might be at higher risk for having a serious allergic reaction to the contrast material (e.g., rash, chills, and fever) after receiving Proleukin (aldesleukin).
Proleukin (aldesleukin) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Heart problems | Lung problems | Kidney problems | Liver problems
Proleukin (aldesleukin) can cause a rare, but life-threatening side effect called capillary leak syndrome (CLS). This is a condition where fluids and proteins leak out of the blood vessels into surrounding tissues. In serious cases, CLS can result in complications such as sudden drop in blood pressure, chest pain, heart attack, and breathing problems.
Because of the risk of CLS, you’ll only receive Proleukin (aldesleukin) at a facility with trained medical staff who can give you emergency treatment in case you experience CLS. Your provider will check your vital signs and other labs before you start Proleukin (aldesleukin) and regularly during treatment. If you develop CLS, your provider might need to stop Proleukin (aldesleukin) to treat CLS symptoms. Let your provider know if you experience any signs of symptoms of CLS like changes in your amount of urine, trouble breathing, or confusion.
Risk factors: Current infections | Indwelling central lines
Proleukin (aldesleukin) can raise your risk of getting a serious infection. Sometimes, this can lead to complications like sepsis or bacterial endocarditis. If you currently have an infection, your healthcare provider will likely treat it before you start Proleukin (aldesleukin). They might also give your antibiotics to prevent infections, especially if you have a central line. Let your provider know if you experience any signs or symptoms of a new infection like a fever, chills, stuffy nose, cough, ear or sinus pain, pain while urinating, or wounds that won't heal.
Risk factors: Seizures | Cancer that has spread to the brain

CNS problems can go away after you stop Proleukin (aldesleukin), but sometimes they can become permanent. If you notice symptoms of CNS problems are, let your provider know because they might ask you to stop Proleukin (aldesleukin) treatment.
Proleukin (aldesleukin) can cause serious stomach problems like nausea, vomiting, diarrhea, especially for people receiving higher doses of the medication. If your symptoms are mild, your healthcare provider can recommend ways for you to manage them such, as with anti-nausea and anti-diarrheal medications. But if you have more serious symptoms, like dark and tarry stool or stomach pains that don't go away, then your provider might ask you to stop Proleukin (aldesleukin).
Proleukin (aldesleukin) can cause high blood sugar levels, sometimes leading to diabetes. If you already have high blood sugar levels, your provider will check on your labs more often during treatment. If needed, they might adjust the doses of your blood sugar medications. Let your healthcare provider know right away if you experience symptoms of dangerously high blood sugar levels, such feeling very thirsty or confused, urinating more frequently, and sweet smelling breath; you might need more urgent medical attention.
Proleukin (aldesleukin) can cause thyroid gland problems including hypothyroidism. Hypothyroidism usually happens 1 to 4 months after starting treatment with Proleukin (aldesleukin). Symptoms of thyroid gland problems can include weight loss or weight gain, feeling nervous or anxious, depression, eye or neck swelling, feeling hot or cold, sweating, or changes in menstruation. Let your healthcare provider know if you have symptoms of thyroid gland problems as they may need to start you on thyroid replacement medication in some cases.
Proleukin (aldesleukin) can cause autoimmune or inflammatory disorders to worsen. This can include conditions like Crohn's disease, thyroiditis, diabetes, and myasthenia gravis. Let your healthcare provider know if you have a history of an autoimmune or inflammatory disorder.
Risk factors: Taking other medications that can cause liver damage
Proleukin (aldesleukin) can cause damage to the liver. This risk is higher if you are also taking other medications that can harm the liver. If you experience serious liver problems, your healthcare provider might need to stop your treatment with Proleukin (aldesleukin). Let your healthcare provider know right away if you have symptoms of liver problems like dark colored urine, lowered appetite, tiredness, stomach pain, or yellowing of the skin or eyes.
Risk factors: Taking other medications that can cause kidney damage
Proleukin (aldesleukin) can cause damage to the kidneys. This risk is higher if you are also taking other medications that can harm the kidneys or you already have kidney problems. If you experience serious kidney problems, your healthcare provider might need to stop Proleukin (aldesleukin). Let your care team know right away if you have symptoms of kidney problems like being unable to urinate, urinating less frequently or in smaller amounts, blood in your urine, or swelling in your feet or hands.
Proleukin (aldesleukin) can cause skin problems, including a skin reaction called bullous pemphigoid. In rare cases, it can cause severe skin reactions like Stevens-Johnson syndrome (SJS), which can be life-threatening. Tell your provider immediately if you develop painful blisters, skin wounds, peeling skin, mouth sores, or red irritated eyes as these are signs of a serious skin reaction that requires medical attention.
