WARNING

Idelalisib is a medication used in the treatment of certain types of blood cancers, such as chronic lymphocytic leukemia (CLL) and follicular lymphoma. While it can be effective in managing these conditions, like any medication, it carries certain risks and potential side effects. Here are some of the risks associated with taking Idelalisib:

• Diarrhea: Diarrhea is one of the most common side effects of Idelalisib. It can range from mild to severe and may require medical intervention and dose adjustments.
• Infections: Idelalisib can weaken the immune system, making individuals more susceptible to infections. Patients taking this medication may experience frequent infections, such as pneumonia or urinary tract infections.
• Hepatotoxicity: Idelalisib has been associated with liver problems, including severe liver injury and hepatotoxicity. Regular monitoring of liver function is required during treatment.
• Colitis: Idelalisib can cause inflammation of the colon, leading to symptoms like abdominal pain, diarrhea (which can be severe), and gastrointestinal bleeding. Close monitoring is necessary, and treatment may involve the discontinuation of Idelalisib.
• Lung toxicity: Some patients taking Idelalisib have experienced lung problems, including inflammation and lung infections. Symptoms may include coughing, difficulty breathing, and fever.
• Pneumocystis jirovecii pneumonia (PJP): Idelalisib treatment increases the risk of PJP, a serious fungal infection affecting the lungs. Patients may need prophylactic medication to prevent this infection.
• QT interval prolongation: Idelalisib can cause an abnormality in the electrical activity of the heart, leading to a potentially life-threatening condition called QT interval prolongation. Regular cardiac monitoring is necessary.
• Immunological effects: Idelalisib can affect the body’s immune system, leading to changes in lymphocyte counts and increasing the risk of autoimmune conditions.

It’s important to note that these risks may vary in severity from person to person. Patients considering Idelalisib should have a thorough discussion with their healthcare provider about the potential risks and benefits of this medication, as well as any specific considerations based on their individual health profile.

Why is this medication prescribed?

Idelalisib is prescribed for the treatment of certain types of blood cancers, specifically chronic lymphocytic leukemia (CLL) and follicular lymphoma. It is used in specific situations when other treatments have been unsuccessful or are not suitable for the patient.

• Chronic Lymphocytic Leukemia (CLL): Idelalisib is prescribed for patients with CLL who have received at least one prior therapy. It is often used in combination with other medications, such as rituximab, to target cancer cells and slow down the progression of the disease.
• Follicular Lymphoma: Idelalisib is prescribed for patients with follicular lymphoma who have received at least two prior therapies. It is typically used in combination with rituximab to treat this slow-growing type of non-Hodgkin lymphoma.

Idelalisib belongs to a class of medications known as kinase inhibitors. It works by blocking specific enzymes called phosphoinositide 3-kinase (PI3K) delta, which are involved in the growth and survival of cancer cells. By inhibiting these enzymes, Idelalisib helps to control the growth of cancer cells and may prolong the time before the disease progresses.

How should this medicine be used?

Here are some general guidelines for using Idelalisib:

• Follow Prescription Instructions: Take Idelalisib exactly as directed by your healthcare provider. Do not change the dosage or treatment schedule without consulting them.
• Take with or without Food: Idelalisib can be taken with or without food. Follow the instructions provided by your healthcare provider or the medication label.
• Swallow the Tablet Whole: Do not crush, chew, or break the Idelalisib tablets. Swallow them whole with water or another beverage.
• Stick to the Schedule: Take Idelalisib at the same time(s) each day to maintain a consistent level of the medication in your body. It is important to adhere to the prescribed treatment schedule.
• Do Not Miss Doses: If you forget to take a dose, take it as soon as you remember. However, if it is close to the time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.
• Store Properly: Store Idelalisib tablets at room temperature, away from heat, moisture, and direct light. Follow any specific storage instructions provided with the medication.
• Regular Check-ups: Your healthcare provider will monitor your progress and may order blood tests or other assessments to evaluate your response to Idelalisib and manage any potential side effects. Attend all scheduled appointments and communicate any concerns or changes in your health.

It’s crucial to communicate openly with your healthcare provider about any questions, concerns, or side effects you may experience while taking Idelalisib. They can provide personalized guidance and support throughout your treatment.

Other uses for this medicine

Idelalisib is primarily used for the treatment of chronic lymphocytic leukemia (CLL) and follicular lymphoma. However, it is important to note that Idelalisib should only be used under the guidance and prescription of a healthcare professional specializing in cancer treatment. It is not recommended for other uses or conditions unless specifically prescribed by a healthcare provider.

What special precautions should I follow?

As for special precautions, here are some important points to consider:

• Medical History: Provide your healthcare provider with a comprehensive medical history, including any previous or existing medical conditions, especially liver problems, lung disorders, or infections.
• Medications and Supplements: Inform your healthcare provider about all the medications, supplements, and herbal products you are currently taking or planning to take. Certain medications, including those metabolized by the liver, may interact with Idelalisib and require dose adjustments or avoidance.
• Pregnancy and Breastfeeding: Idelalisib can harm an unborn baby, so it is important to discuss the potential risks and benefits with your healthcare provider if you are pregnant or planning to become pregnant. Additionally, it is not known whether Idelalisib passes into breast milk, so breastfeeding should be avoided during treatment.
• Liver Function: Idelalisib can cause liver problems, including severe liver injury. Regular monitoring of liver function tests is necessary during treatment. If you experience symptoms such as yellowing of the skin or eyes, dark urine, abdominal pain, or persistent nausea, inform your healthcare provider immediately.
• Infections: Idelalisib can increase the risk of infections, including serious fungal infections like Pneumocystis jirovecii pneumonia (PJP). Prophylactic medications may be prescribed to prevent such infections. Notify your healthcare provider if you develop signs of infection, such as fever, cough, or urinary tract symptoms.
• QT Interval Prolongation: Idelalisib can cause abnormal heart rhythms, specifically prolongation of the QT interval. It is important to inform your healthcare provider if you have a history of heart problems or take other medications that can prolong the QT interval.

These are general precautions, and it is essential to consult your healthcare provider for personalized guidance based on your specific medical situation before starting Idelalisib treatment. They will consider your individual risks, benefits, and any additional precautions necessary for your well-being.
