Quick summary

IBRANCE 100 mg film-coated tablets are used in breast cancer treatment plans, usually as part of combination therapy. This guide explains the main uses, common safety points, possible interactions, and what to check with your oncology team or pharmacist.

Medical disclaimer: This article is for general information only and does not replace advice from your oncologist, pharmacist, or the official patient leaflet. Do not use it to self-diagnose, start, stop, or change any treatment.

What is IBRANCE 100 mg used for?

IBRANCE 100 mg film-coated tablets are used in the treatment of hormone receptor-positive, HER2-negative breast cancer. The original content describes it as part of modern breast cancer treatment, often used with other hormonal therapies.

Because treatment plans vary, the exact reason for use should always be confirmed with the prescribing oncology team.

How IBRANCE is usually taken

The original content states that IBRANCE is typically prescribed in a three weeks on, one week off schedule. It can be taken with or without food, and taking it consistently at the same time each day is important.

Do not alter the prescribed schedule without medical advice. If a dose is missed, the original content advises taking it when remembered unless it is close to the next dose, in which case it should be skipped rather than doubled.

What should I know before using IBRANCE?

Before treatment starts, it is important to tell your healthcare provider about:

  • Any allergies, including allergies to tablet ingredients
  • Any existing medical conditions
  • All prescription medicines, over-the-counter products, and supplements
  • Pregnancy or breastfeeding status

The original content notes that pregnancy and breastfeeding should be discussed with a healthcare provider, and that effective contraception may be recommended during treatment.

Medicine and supplement interactions

IBRANCE may interact with other medicines, especially those that affect liver enzymes. These interactions can change how the medicine works or increase the risk of side effects.

It is also important to mention herbal products, traditional remedies, and supplements, since these may also affect treatment.

What to review Why it matters
Prescription medicines Some may interact with IBRANCE
Over-the-counter products They can still affect treatment
Herbal supplements They may change how the medicine is processed
Traditional remedies These should also be checked for interactions

What should I know while using IBRANCE?

Regular follow-up is important during treatment. The original content says blood tests may be needed to monitor white blood cell counts and other parameters.

Watch for signs of infection, such as fever or chills, and report unexplained bruising or other concerning symptoms promptly to your healthcare team.

For storage, the original content advises keeping the tablets at room temperature, away from moisture and heat, and out of reach of children.

Possible side effects

The original content lists fatigue, nausea, and diarrhea among common side effects. It also highlights neutropenia as a more serious risk that can increase the chance of infection.

Mouth sores and changes in appetite are also mentioned. Any persistent, severe, or worrying symptoms should be discussed with a healthcare professional.

IBRANCE tablets vs capsules

The original content explains that the active ingredient is the same, but the dosage form differs. It also states that IBRANCE capsules have been discontinued, while film-coated tablets are available in 75 mg, 100 mg, and 125 mg strengths.

If you have questions about the form prescribed to you, check the label and confirm with your pharmacist or oncology team.

Food and drink considerations

The original content specifically advises avoiding grapefruit and grapefruit juice while taking IBRANCE.

It also suggests discussing diet with a healthcare professional if digestive symptoms occur. For any food-related concerns, the official leaflet or your pharmacist is the best source of guidance.

Safety reminder

Contact your healthcare team promptly if you develop fever, chills, signs of infection, unusual bruising, or side effects that are severe or do not improve. Do not make treatment changes on your own.
