Why is this medication prescribed?

Ibrance is prescribed for the treatment of hormone receptor-positive, human epidermal growth factor receptor 2-negative (HR+/HER2-) advanced or metastatic breast cancer. This type of breast cancer is sensitive to hormones, specifically estrogen, and does not overexpress the HER2 protein.

Ibrance is used in combination with other medications, such as an aromatase inhibitor or fulvestrant, to slow down the growth and spread of cancer cells. The medication works by inhibiting certain proteins called cyclin-dependent kinases (CDK) 4 and 6, which are involved in the regulation of cell division. By blocking these proteins, Ibrance helps to prevent cancer cells from dividing and growing.

The combination of Ibrance with other medications has been shown to extend the progression-free survival (the length of time during treatment when the cancer does not worsen) in patients with advanced or metastatic breast cancer. It provides an additional treatment option for postmenopausal women or men with HR+/HER2- breast cancer who have not received prior systemic therapy for their advanced disease or have progressed after prior endocrine therapy.

How should this medicine be used?

Ibrance should be used according to the instructions provided by your healthcare provider. It is important to follow the prescribed dosage and schedule. Here are some general guidelines for the use of Ibrance, but it’s crucial to consult with your doctor for personalized advice:

• Dosage: The dosage of Ibrance will be determined by your healthcare provider based on various factors, including your specific condition and other medications you may be taking. The typical starting dose of Ibrance is 125 mg, taken orally once daily for 21 consecutive days, followed by a break of 7 days (known as a treatment cycle). Your doctor may adjust the dosage as needed.
• Administration: Ibrance comes in the form of capsules. Swallow the capsules whole with a glass of water. Do not chew, crush, or open the capsules.
• Timing: Take Ibrance at approximately the same time each day to maintain consistent levels of the medication in your body.
• Combination therapy: Ibrance is typically used in combination with other medications, such as an aromatase inhibitor (e.g., letrozole, anastrozole) or fulvestrant. Take the prescribed combination therapy as instructed by your doctor. The other medication may have its own specific dosing instructions.
• Food and beverages: Ibrance can be taken with or without food. However, it’s recommended to take it consistently either with food or on an empty stomach, as food can affect the absorption of the medication.
• Duration: Your doctor will determine the duration of treatment with Ibrance. It may be prescribed for as long as it is effective in controlling the cancer or until you experience intolerable side effects.
• Follow-up appointments: Regularly visit your healthcare provider for follow-up appointments and monitoring of your progress. Your doctor may adjust the dosage or schedule based on your response to treatment and any side effects you may experience.

Remember, it is essential to strictly adhere to the instructions provided by your healthcare provider. If you have any questions or concerns about the use of Ibrance, it’s important to discuss them with your doctor or pharmacist for clarification and guidance.

Other uses for this medicine

Ibrance (palbociclib) is primarily prescribed for the treatment of hormone receptor-positive, human epidermal growth factor receptor 2-negative (HR+/HER2-) advanced or metastatic breast cancer. However, there may be instances where healthcare providers prescribe medications for off-label use, which means using a medication for a purpose other than its approved indication. It’s important to note that the off-label use of Ibrance should be determined by a healthcare professional based on their clinical judgment and evaluation of the individual’s specific condition.

What special precautions should I follow?

Regarding special precautions for Ibrance, it’s crucial to discuss these with your healthcare provider, as they can provide personalized guidance based on your medical history and current health status. However, here are some general precautions associated with Ibrance use:

• Pregnancy and breastfeeding: Ibrance may cause harm to unborn babies, so it is not recommended during pregnancy. If you are a woman of childbearing potential, you should use effective contraception during treatment with Ibrance and for at least three weeks after the last dose. It is not known if Ibrance passes into breast milk, so breastfeeding should be avoided while taking Ibrance.
• Liver function: Ibrance may affect liver function. Your doctor may monitor your liver function through blood tests before and during treatment. Inform your healthcare provider if you have a history of liver disease or if you experience symptoms such as yellowing of the skin or eyes, dark urine, or persistent nausea and vomiting, as these may be signs of liver problems.
• Low blood cell counts: Ibrance can cause a decrease in white blood cell counts, which may increase the risk of infection. Your doctor will monitor your blood cell counts regularly. Inform your doctor if you experience symptoms such as fever, chills, sore throat, or any signs of infection.
• Interactions with other medications: It is important to inform your healthcare provider about all the medications, supplements, and herbal products you are taking, as Ibrance may interact with certain medications, including those that affect liver enzymes or medications that can cause QT prolongation (a type of abnormal heart rhythm).
• Side effects: Like any medication, Ibrance can cause side effects. Common side effects include fatigue, nausea, decreased appetite, hair thinning or hair loss, diarrhea, and infections. However, everyone may respond differently to treatment. It is essential to report any new or worsening symptoms to your doctor.

These precautions are not exhaustive, and there may be additional factors to consider based on your specific situation. It is crucial to have open and regular communication with your healthcare provider regarding any concerns or questions you may have about Ibrance.
