Selinexor (Xpovio®)

Store your medication in the original container with the label. If you want to use a pillbox, talk to your pharmacist. Keep it in a dry place at room temperature unless your provider or pharmacist tells you otherwise. Keep containers out of reach of children and pets.

If a caregiver prepares your dose for you, they should consider wearing gloves or pour the pills directly from their container into the cap, a small cup, or directly into your hand. They should avoid touching the pills. They should always wash their hands before and after giving you the medication. Pregnant or nursing people should not prepare the dose for you. Ask your provider where to return any unused medication for disposal. Do not flush down the toilet or throw in the trash. 

Some cancer medications are only available through specialty pharmacies. Your provider or pharmacist will start this process. Your insurance plan may also affect where you can get your medication.  Call your prescription plan provider to find out which specialty pharmacies are in-network.

This medication may be covered by your prescription plan. If you qualify, you may be able to get financial help through patient assistance programs (PAP). Co-pay cards may also be available to lower your out-of-pocket cost if you have commercial (not Medicare/Medicaid/Tricare) insurance. Your pharmacist, social worker, or navigator can help find resources for financial support.

These are some of the most common or most serious side effects of this medication. Talk with your provider about the side effects you are having and how they can be managed.

Platelets are blood cells that help your blood clot. Thrombocytopenia is when your platelet count is lower than normal, and you are at a higher risk of bleeding. Tell your providers if you have any bruising or bleeding, including nose bleeds, bleeding gums, or blood in your urine or stool. If your count gets too low, you may receive platelets from a donor. 

• Do not use a razor (an electric razor is fine).
• Do not do activities that can cause injury or bleeding.
• Talk to your provider before taking any non-steroidal, anti-inflammatory medications (NSAIDs) like Motrin/Advil (ibuprofen), Aleve (naproxen), Celebrex (celecoxib), and others. These can raise the risk of bleeding. 
• Use a soft-bristle toothbrush to brush your teeth. Ask your provider about flossing or using toothpicks. 

Fatigue can cause exhaustion, feeling worn out and that your body is "heavy" and hard to move, or being unable to focus. It is common when you have cancer, and it is not the same as feeling tired. You may need to adjust your schedule to manage fatigue. Plan times to rest during the day and save your energy for more important activities. Exercise can help lessen fatigue. Talk to your providers about ways to deal with this side effect.

Talk to your providers if you have nausea and/or vomiting. They can prescribe medications to help you. Making changes to your diet can also help. Avoid things that make your symptoms worse, like heavy or greasy/fatty foods and spicy or acidic foods, like tomatoes, lemons, and oranges. Try saltines or ginger ale to help your symptoms.  

Call your providers if you cannot keep fluids down for more than 12 hours or if you feel lightheaded or dizzy.

Anemia is when your red blood cell count is lower than normal. Red blood cells carry oxygen to the tissues in your body. When your red cell count is low, you may feel tired or weak. Tell your providers if you have shortness of breath, trouble breathing, or pain in your chest. If your count gets too low, you may receive a blood transfusion.

Nutrition is an important part of your care. Cancer treatment can affect your appetite and make it hard to eat. Ask your provider about nutrition counseling services. Some tips you can follow are:

• Try to eat five or six small meals or snacks during the day, instead of 3 larger meals.
• Nutritional supplements may help if you are not eating enough.
• You may have a metallic taste or find that food has no taste. You may dislike foods or beverages that you liked before cancer treatment. These symptoms can last for months or longer after treatment ends.
• Avoid any food that you think smells or tastes bad. If red meat is a problem, eat chicken, turkey, eggs, dairy products, and fish without a strong smell. Sometimes cold food has less of an odor.
• Add extra flavor to meat or fish by marinating it in sweet juices, sweet and sour sauce, or dressing.
• Use seasonings like basil, oregano, or rosemary to add flavor.

Diarrhea is when you pass three or more stools in a day. Your providers can suggest medications to relieve diarrhea. Do not take any medications to manage your diarrhea without talking to your provider first, as your stool may need to be tested. To manage it, try eating foods that are low in fiber and bland, like white rice and boiled or baked chicken. Try not to eat raw fruits, vegetables, whole grain breads, cereals, and seeds. Soluble fiber is a type of fiber found in some foods that helps absorb (soak up) fluid. Foods high in soluble fiber are applesauce, bananas (ripe), canned fruit, oranges, boiled potatoes, white rice, foods made with white flour, oatmeal, cream of rice, cream of wheat, and farina. Stay hydrated by drinking 8 to 10 glasses of non-alcoholic, non-caffeinated fluid each day.

This medication can affect your electrolytes (potassium, magnesium, sodium, calcium, etc.). Your electrolyte levels will be checked with blood tests. If your levels get too low, you may be given electrolytes by IV (intravenously through your vein) or by mouth. Talk to your provider before taking any supplements. 

This medication can cause serious infections, with or without a decrease in white blood cell counts.

White blood cells (WBC) help your body fight infection. While you are having cancer treatment, your WBC count can drop, putting you at a higher risk of an infection. Tell your provider right away if you have a fever (a temperature greater than 100.4°F or 38°C), sore throat or cold, shortness of breath, cough, burning with urination, or a sore that doesn't heal.

Tips for preventing infection:

• Hand washing,  both yours and your visitors, is the best way to prevent the spread of infection.
• Avoid large crowds and people who are sick (those who have a cold, fever, or cough, or if someone you live with has these symptoms).
• When working outside, wear clothes that protect you, like long pants and gloves.
• Do not handle pet waste.
• Keep all cuts and scratches clean.
• Shower or bathe daily.
• Brush your teeth at least twice a day.
• Do not cut cuticles or ingrown nails. You may wear nail polish, but not fake nails.
• Ask your providers before scheduling dental appointments or procedures.

Ask your providers before you or someone you live with has any vaccines. 

Your brain, spinal cord, and nerves make up your nervous system. This medication can cause brain (neurological) changes that can affect other parts of your body through your nervous system. You may have 

• Headaches.
• Numbness or tingling (neuropathy).
• Motor skill changes, like loss of control of your arms or legs.
• A hard time understanding when someone speaks to you or being unable to speak as you normally would (called aphasia).
• A change in your mental status, such as confusion, extreme tiredness (lethargy), memory loss, being unable to focus, sleep problems, and seeing or hearing things that aren’t really there (hallucinations), among others.
• A lack of blood flow and oxygen to your brain (called encephalopathy). 
• Seizures.

Call your provider if you are having any neurological symptoms.

Constipation is when you have less bowel movements than usual or are having trouble passing stool. To relieve constipation, you can include fiber in your diet (fruits like prunes, apples, peaches, and pear nectars/juices), drink 8 to 10 glasses of non-alcoholic fluids a day, and stay active. Taking a stool softener once or twice a day can prevent constipation. If you do not have a bowel movement for 2 to 3 days, call your provider.
