Quick summary

IBRANCE 100 mg film-coated tablets contain palbociclib and are used as part of treatment for certain types of breast cancer. This page explains the main safety points, common monitoring needs, possible side effects, and practical questions to discuss with your healthcare team.

Medical disclaimer: This article is for general information only and does not replace the official patient leaflet, prescribing information, or advice from your doctor, pharmacist, or oncology team. Do not use it to diagnose a condition or to change your treatment plan.

What is IBRANCE 100 mg used for?

IBRANCE 100 mg film-coated tablets are used in the treatment of certain types of breast cancer. The medicine is part of a broader treatment plan and is designed to be used together with other therapies.

The active ingredient is palbociclib. If you have been prescribed this medicine, your healthcare team will explain how it fits into your overall treatment plan.

What should I know before using IBRANCE?

Before treatment starts, it is important to discuss your full medical history with your healthcare provider. The original content highlights liver impairment and previous lung disease as conditions that should be mentioned during the consultation.

Pregnancy is another important safety issue. The original content states that effective contraception should be used during treatment and for at least three weeks afterward. If pregnancy is possible, this should be discussed with your healthcare team before treatment begins.

Regular blood tests are also important because IBRANCE can affect blood counts. Monitoring helps your healthcare team check for neutropenia, which means a lower white blood cell count and a higher risk of infection.

What if I am taking other medicines?

Tell your doctor or pharmacist about all medicines you use, including prescription medicines, over-the-counter products, vitamins, and supplements.

The original content notes that medicines affecting the liver enzyme CYP3A may interact with IBRANCE. Because interactions can change how a medicine works or increase side effects, it is important to have your full medication list reviewed by a healthcare professional.

How do I use IBRANCE?

IBRANCE 100 mg film-coated tablets are taken once daily at the same time each day. They may be taken with or without food, but it is best to be consistent.

The original content describes a treatment cycle of three weeks on treatment followed by one week off. Weekly blister packs are included to help support the schedule.

  • Take the medicine exactly as prescribed.
  • Do not take more than the prescribed amount.
  • If you miss a dose, follow the instructions given by your healthcare team or the official leaflet.
  • Do not double a dose to make up for a missed one.

What should I know while using IBRANCE?

Regular blood monitoring is an important part of treatment. Your healthcare team may check your blood counts more often if needed.

Watch for signs of infection such as fever, chills, or a persistent cough. The original content says these symptoms may need prompt medical attention.

It also mentions interstitial lung disease as a possible serious concern. Report any new or worsening breathing symptoms to your healthcare provider.

What are the possible side effects?

The original content lists several common side effects, including:

  • Fatigue
  • Nausea
  • Alopecia, or hair loss
  • Stomatitis, or inflammation in the mouth

Not everyone will experience these effects. If side effects occur, your healthcare team can advise on the next step based on your situation.

Serious side effects mentioned in the original content include severe allergic reactions and interstitial lung disease. Seek urgent medical help if you notice severe or rapidly worsening symptoms.

What is the difference between IBRANCE capsules and tablets?

The original content explains that capsules and film-coated tablets are different dosage forms of IBRANCE, and both contain palbociclib. They may differ in how they are formulated and how they are used in practice.

If you have been prescribed one form, use the form and strength specified by your healthcare provider. Do not assume the capsule and tablet versions are interchangeable.

How much does IBRANCE cost per month?

The cost of IBRANCE can vary widely depending on insurance coverage, pharmacy pricing, and local access. The original content gives an example range of $10,000 to $15,000 per month without insurance.

For the most accurate information, check with your insurer, pharmacy, or treatment center. Some patients may also be able to ask about financial assistance options.

What to verify with your doctor or pharmacist

If you are prescribed IBRANCE, it can help to confirm the following:

  • Which form and strength you should take
  • How your treatment cycle is scheduled
  • Which medicines or supplements may interact with it
  • How often blood tests are needed
  • What symptoms should prompt urgent medical advice
