Enasidenib 100mg Side Effects: What Patients and Caregivers Should Know
24 Oct 2026
Understanding the side effects of cancer medicines is essential for patients and caregivers who want to manage treatment safely. Enasidenib 100mg tablet in Delhi may be searched for by patients receiving treatment for certain types of acute myeloid leukaemia (AML), a cancer affecting blood-forming cells. This targeted therapy can cause digestive problems, changes in appetite, abnormal blood test results, and potentially serious complications. Knowing which symptoms are common and which require immediate medical attention can help patients work closely with their haematologist and recognise problems early.
What Is Enasidenib 100mg Tablet Used For?
Enasidenib is a targeted anticancer medicine used to treat adults with relapsed or refractory acute myeloid leukaemia carrying a specific mutation in the IDH2 gene. Relapsed AML means the cancer has returned after treatment, while refractory AML means it has not responded adequately to previous treatment.
The medicine, marketed under the brand name Idhifa in the United States, belongs to a class called isocitrate dehydrogenase-2 (IDH2) inhibitors. It targets an abnormal enzyme produced by the mutated IDH2 gene, helping immature blood cells develop towards a more normal state.
Although enasidenib can provide a treatment option for eligible patients, it requires specialist supervision. The prescribed dose, treatment duration, and monitoring schedule depend on the patient's condition and response to therapy.
What Are the Common Enasidenib 100mg Side Effects?
Like other targeted cancer medicines, enasidenib can cause unwanted reactions. Some are manageable with supportive care, while others may require medical assessment or changes to treatment.
According to official prescribing information, common adverse reactions include nausea, vomiting, diarrhoea, decreased appetite, elevated bilirubin, and changes in taste. Their severity varies between individuals, and not every patient experiences all of them.
1. Nausea and Vomiting
Nausea and vomiting may affect appetite, hydration, and daily comfort. Patients should inform their healthcare team if these symptoms persist, become severe, or make it difficult to keep fluids down.
Eating smaller meals, drinking fluids as advised, and following the prescribed anti-nausea plan may help. Persistent vomiting needs prompt assessment because dehydration can complicate cancer treatment.
2. Diarrhoea
Diarrhoea can cause abdominal discomfort, fluid loss, and weakness. Patients should monitor how frequently it occurs and report persistent or worsening symptoms.
A healthcare professional may recommend appropriate medication and fluid replacement. Severe diarrhoea, dizziness, reduced urination, or inability to drink enough fluids warrants urgent medical advice.
3. Reduced Appetite and Taste Changes
Some patients experience a reduced appetite or notice that food tastes different. These effects may make it difficult to maintain adequate nutrition during treatment.
Caregivers can help by offering small, frequent meals and keeping track of food and fluid intake. If weight loss continues, a doctor or oncology dietitian can suggest suitable nutritional support.
4. Elevated Bilirubin
Bilirubin is a yellow pigment produced when red blood cells break down. Enasidenib can increase bilirubin levels in blood tests, sometimes without other signs of liver injury.
However, yellowing of the skin or whites of the eyes, known as jaundice, should never be ignored. Patients should contact their treating team promptly so the cause can be assessed through examination and laboratory testing.
Serious Warning: Differentiation Syndrome
One of the most important risks associated with enasidenib is differentiation syndrome. This potentially life-threatening complication occurs when developing blood cells undergo changes that trigger inflammation and fluid accumulation in different parts of the body.
Symptoms may appear early in treatment or several months later. Patients and caregivers should not assume that new symptoms are simply routine side effects.
Warning signs include:
Fever, cough, or difficulty breathing.
Sudden weight gain or swelling of the arms and legs.
Reduced urination or signs of kidney problems.
Chest discomfort or new bone pain.
If these symptoms develop, seek immediate medical assessment and tell the healthcare team that the patient is taking enasidenib. Do not wait for the next scheduled appointment. Differentiation syndrome can be fatal without timely treatment, but prompt recognition and appropriate medical management can improve outcomes.
Other Serious Risks Patients Should Know About
Beyond common digestive symptoms and differentiation syndrome, enasidenib can cause other complications that require monitoring.
Tumour lysis syndrome: When cancer cells break down rapidly, substances released into the bloodstream can disrupt electrolyte balance and affect kidney function. Symptoms may include nausea, weakness, muscle cramps, or reduced urination. Doctors may recommend blood tests and other preventive measures based on individual risk.
Non-infectious leukocytosis: The white blood cell count may rise during treatment. Your specialist will assess blood results and decide whether additional treatment or monitoring is necessary.
Electrolyte abnormalities: Changes in calcium, potassium, and phosphorus can occur. Significant abnormalities may affect muscles, nerves, or heart rhythm and require medical management.
Pregnancy-related risks: Enasidenib may harm an unborn baby. Patients who are pregnant, planning pregnancy, or could become pregnant should discuss the risks and effective contraception with their specialist. Breastfeeding should also be discussed with the treating team.
How Can Patients and Caregivers Manage Side Effects?
Safe management starts with communication, regular monitoring, and following the treatment plan. Patients should never change their dosage or stop taking enasidenib independently because symptoms appear manageable or treatment seems difficult.
Caregivers can support treatment by keeping a record of symptoms, temperature changes, weight fluctuations, fluid intake, and any unusual changes in behaviour or breathing. This information helps the medical team identify developing complications.
The following habits can also support safer treatment:
Attend scheduled blood tests and specialist appointments.
Maintain hydration and nutrition according to medical advice.
Keep an updated list of prescription medicines, supplements, and over-the-counter products.
Report new symptoms promptly rather than waiting for them to worsen.
Enasidenib can interact with other medicines by changing how certain drugs are processed in the body. Patients should consult their doctor or pharmacist before starting any new medicine or supplement.
