Pharmacist tips for Nexavar (sorafenib)
- Take Nexavar (sorafenib) tablets on an empty stomach, at least 1 hour before or 2 hours after a meal. Swallow the tablet whole with water. Don’t crush, break, or chew it because doing so can cause you harm.
- If you miss a dose of Nexavar (sorafenib), skip it and take the next dose at the regularly scheduled time. Don’t take two doses at the same time to make up for your missed dose because this can raise your risk of harm.
- Check your blood pressure at least once a week while taking Nexavar (sorafenib). This medication can raise your blood pressure. If your blood pressure gets too high while taking Nexavar (sorafenib), your healthcare provider might prescribe blood pressure medications to help manage this problem.
- Since Nexavar (sorafenib) commonly causes rash, keep your skin well hydrated by applying moisturizing creams regularly to your hands and feet. Protect the skin on your feet by avoiding too much friction and wear thick cotton socks or shoes with padded insoles. Let your healthcare provider know right away if you have any redness, blistering, or peeling of your skin.
- Let your healthcare provider know if you’re planning to have surgery. You might need to stop Nexavar (sorafenib) several days before surgery. You also might need to wait until at least a couple weeks after surgery and until your surgical wounds are fully healed to restart the medication. This is because Nexavar (sorafenib) can slow wound healing and cause bleeding.
- If you or your partner can have children, use effective birth control during treatment with Nexavar (sorafenib). After taking your last dose of medication, continue to use birth control for at least 3 months (for men with partners who can become pregnant) or for at least 6 months (for women who can get pregnant). Nexavar (sorafenib) can harm an unborn baby. If you think you or your partner has become pregnant while you’re taking this medication, tell your healthcare provider right away.
- Ask your provider or pharmacist about the best way to handle and throw away Nexavar (sorafenib) safely. Anticancer medications can be very harmful to people who handle or come into contact with them.
Risks and warnings for Nexavar (sorafenib)
Nexavar (sorafenib) 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.
Heart problems
- Risk factors: History of prolonged QT interval | Taking other medications that cause QT prolongation
Nexavar (sorafenib) can cause heart problems, like less blood flow to the heart, heart attack, and heart failure. It can also cause changes in the electrical activity of your heart known as QT prolongation, raising the risk for life-threatening irregular heartbeats. During treatment, your healthcare provider might check the levels of electrolytes in your blood and the electrical activity of your heart with an electrocardiogram (ECG). Let your provider know right away if you have symptoms like chest pain, shortness of breath, swelling in lower legs or feet, racing or irregular heartbeat, feeling faint or lightheaded, or tiredness. If you develop heart problems while taking Nexavar (sorafenib), your provider may recommend you stop taking it.
Bleeding
Nexavar (sorafenib) can raise the risk of serious and sometimes fatal bleeding. Bleeding can happen in any area of the body, including in the lungs, digestive tract, and less commonly, the brain. Tell your healthcare provider as soon as possible if you have symptoms of unusual bleeding, like vomiting blood, blood in your urine, abnormal vaginal bleeding, blood in your stool, coughing up blood, frequent nosebleeds, or bruising easily. Your provider might recommend you to stop taking Nexavar (sorafenib) if you experience serious bleeding.
If you also take the blood thinner warfarin (Coumadin), you might experience changes in your INR (international normalized ratio) and put you at higher risk of bleeding. Your healthcare provider might recommend that you get your warfarin (Coumadin) blood checks more frequently.
High blood pressure
Nexavar (sorafenib) can commonly cause high blood pressure. This change in blood pressure is usually mild, but can be more severe in some cases. It typically happens when you first start Nexavar (sorafenib). Because of this, you should check your blood pressure every week for the first 6 weeks of treatment and then regularly thereafter. If you develop high blood pressure while taking Nexavar (sorafenib), your healthcare provider might recommend that you take blood pressure medication(s). If your blood pressure gets severely high, you might be recommended to stop taking Nexavar (sorafenib).
Skin reactions
Nexavar (sorafenib) can cause serious skin reactions, including serious rash and hand-foot skin reaction. Reactions can also happen in the mouth and look like blistering or peeling inside of your mouth. These skin and mouth reactions can become life-threatening. Let your healthcare provider know if you experience any skin rash or redness, pain, swelling, blistering or peeling of the skin on your body or inside your mouth, or blistering on the palms of your hands or soles of your feet. Some skin reactions can be managed with topical treatments like hydrating lotions or urea-based creams. But if they become severe, your healthcare provider might recommend that you stop taking Nexavar (sorafenib).
Damage to the digestive tract
Though rare, some people who took Nexavar (sorafenib) have developed tears in their gut. Let your provider know if you have symptoms of gut damage, such as a fever, nausea, vomiting, bloating, tenderness, or a lot of stomach pain or cramping (especially if it doesn’t go away).
Problems healing from surgery and wounds
Nexavar (sorafenib) can make it more difficult for your wounds to heal. Let your provider know if you’re planning to have a surgery or procedure so they can adjust your treatment plan. You shouldn’t take Nexavar (sorafenib) at least 10 days before surgery. And you won’t be able to restart the medication until at least 2 weeks after the surgery and until your surgical wounds have properly healed.
In addition, if you get injured while you’re taking Nexavar (sorafenib) and your wounds are healing very slowly, let your provider know. Your provider might ask you to temporarily stop this medication until your injuries have healed.
Liver problems
Although rare, Nexavar (sorafenib) can cause liver damage, which can sometimes lead to liver failure and even death. Your healthcare provider will perform blood tests to check your liver function regularly during your treatment with Nexavar (sorafenib). Let your healthcare provider know right away if you experience any symptoms of liver damage, like yellowing of the skin or eyes, pain on the right side of your stomach, dark urine, light-colored stools, loss of appetite, or severe nausea or vomiting.
Harm to an unborn baby
Based on animal studies, it’s possible that Nexavar (sorafenib) can cause harm to an unborn baby when taken during pregnancy. If you can get pregnant, your provider will ask you to use birth control while you’re taking Nexavar (sorafenib) and for 6 months after your last dose. Men with female partners who can become pregnant should also use birth control while they’re taking Nexavar (sorafenib) and for 3 months after their last dose of medication. Let your provider know right away if you or your partner become pregnant during this time frame.
Change in thyroid hormone levels in people with thyroid cancer
If you have differentiated thyroid cancer, you can have changes in your thyroid hormone levels during treatment with Nexavar (sorafenib). Your healthcare provider will check your thyroid hormone levels through blood tests every month during treatment. If you’re also taking a thyroid medication, your healthcare provider might need to adjust its dose based on your lab results. This helps stabilize your thyroid hormone levels.
