Ibrance is taken once a day for 21 days at a dose of 125 mg. Then there’s a seven-day period where no drugs are used. This 28-day cycle is repeated as as your doctor suggests. If you have problems with your liver function or are taking other medications, your doctor may prescribe a lower dose. If you experience certain side effects, such as low blood cell counts, your doctor may reduce your dosage or have you stop treatment. Always take Ibrance as directed by your doctor.

Take the next dose at regular intervals. To make up for a missed dose, do not take an extra dose. Set a reminder on your phone to help you remember not to miss a dose. A drug timer can also be beneficial. Ibrance (palbociclib) is a drug that comes in pill or tablet form and is taken by mouth to treat some types of breast cancer.

It’s important to note that Ibrance should not be used by women who are pregnant or intending to become pregnant. Doctors are unsure if Ibrance would hurt your unborn child. You mustn’t become pregnant while taking Ibrance. You have to use requisite birth control if you are undergoing this Ibrance treatment and for a minimum period of two weeks after you took your last dose.


If a male is taking Ibrance who has a female partner and if there is a chance of her becoming pregnant then they should use birth control for a minimum period of 3 months after stopping Ibrance. Ibrance should not be taken by women who are breastfeeding or expect to breastfeed. If you are breastfeeding and your doctor prescribes you to take Ibrance then you should have a proper discussion with your doctor about whether you should take Ibrance or breastfeed.


Doctors prefer to combine Ibrance with an aromatase inhibitor or a fulvestrant for female patients with hormonal therapy. This will be determined by their specific circumstances. Ibrance should not be used in conjunction with any other drugs. Antibiotics, antifungals, and anti-epileptic medications are among the most commonly prescribed medicines. Tell the doctor or dentist that you’re taking Ibrance if they give you a new prescription. Don’t forget to follow all the guidelines mentioned by your doctor.
