What side effects are most common with Tasigna (nilotinib)?
Tasigna (nilotinib) can cause a range of side effects, with the most commonly reported ones including nausea, constipation, rash, fatigue, headache, muscle pain, and low blood counts (such as decreased white blood cells or platelets). [1]
What serious side effects should patients watch for?
Tasigna carries risks that can be clinically important. Patients are typically monitored for effects on heart rhythm, blood counts, and certain lab abnormalities. Serious concerns can include:
- Changes in heart electrical activity (QT prolongation) and related heart rhythm problems [1]
- Severe low blood counts (increasing infection or bleeding risk) [1]
- Pancreatitis and liver problems (elevated liver enzymes) [1]
- Fluid retention and metabolic changes such as elevated cholesterol or triglycerides [1]
Heart rhythm risks: how does Tasigna affect the QT interval?
Tasigna is associated with QT prolongation, which can raise the risk of abnormal heart rhythms. Clinicians often check baseline and follow-up EKGs and review other medications and risk factors that can increase QT risk. [1]
Blood count problems: what does Tasigna do to white cells and platelets?
Nilotinib can suppress bone marrow function, leading to decreases in white blood cells and platelets. Lower counts can increase the risk of infection and bleeding, so blood tests are part of routine monitoring. [1]
Other lab abnormalities patients ask about (lipids and liver tests)
Patients on Tasigna are typically monitored for:
- Elevated triglycerides and cholesterol [1]
- Elevated liver enzymes (liver injury signals) [1]
What symptoms mean patients should get urgent care?
Seek urgent medical attention if Tasigna side effects include signs that could point to heart rhythm problems (such as fainting, severe dizziness, or new palpitations), serious infection (fever with chills), significant bleeding, or severe abdominal pain that could suggest pancreatitis. [1]
Drug interactions: can other medicines increase Tasigna side effects?
Yes. Some drugs can increase Tasigna exposure or increase QT prolongation risk, which can worsen side effects. Your prescriber/pharmacist should review all medicines, including over-the-counter drugs and supplements, before starting or during treatment. [1]
