Verzenio medication basics

Verzenio contains the active ingredient abemaciclib. (An active ingredient is what makes a drug work.) It belongs to a group of medications called cyclin-dependent kinase 4/6 (CDK4/6) inhibitors.

Verzenio is a brand-name medication. It’s not available as a generic medication.

If you have breast cancer, your doctor may prescribe Verzenio for you. Verzenio is a prescription drug that’s used to treat early breast cancer and advanced or metastatic breast cancer in some situations.

Early breast cancer means the cancer has not spread outside of the breast. Advanced or metastatic breast cancer has spread from your breast to other parts of your body.

Verzenio treats breast cancer that’s hormone receptor-positive (HR-positive) and HER2-negative. Having HR-positive breast cancer means that hormones encourage the cancer to grow. And having HER2-negative breast cancer means the cancer cells don’t have certain proteins on them.

Verzenio can be prescribed:

  • as an add-on treatment, together with hormone therapy in adults with early breast cancer that has spread to lymph nodes near the breast and has a high risk of coming back after treatment
  • by itself in adults with advanced or metastatic breast cancer after past hormone treatment and chemotherapy didn’t work and the cancer has become more advanced
  • together with a kind of drug called an aromatase inhibitor (a hormone blocker) in adults with advanced or metastatic breast cancer who haven’t used a hormone treatment for the cancer in the past
  • together with a drug called fulvestrant (Faslodex) in adults who have used hormone treatment in the past but it didn’t work and the cancer has become more advanced

Verzenio works by helping to prevent cancer cells from making more cancer cells. By doing this, Verzenio helps people with cancer to live longer and have a better quality of life.

Your doctor will recommend the dosage of Verzenio that’s right for you. Below are commonly used dosages, but the dosage you take will be determined by your doctor.

Questions about taking Verzenio

Here are some answers to common questions about taking Verzenio.

  • Can Verzenio be chewed, crushed, or split? No, you should not crush, split, or chew Verzenio tablets. There isn’t any information available to know whether doing so changes how the medication works. If you have trouble swallowing Verzenio tablets, talk with your doctor about your treatment options.
  • Should I take Verzenio with food? Verzenio can be taken with or without food. Keep in mind that the drug can cause side effects, such as diarrhea, nausea, and vomiting. So, you can see if it works better for you to take it with food or on an empty stomach. And be sure to talk with your doctor if you have any serious side effects, including abdominal pain, severe diarrhea, nausea, or vomiting.

Like most drugs, Verzenio may cause mild or serious side effects.

More common side mild effects of Verzenio include diarrhea, nausea, and fatigue.

Serious side effects can include blood clots and liver problems. These require monitoring by a healthcare professional.

Whether you have health insurance or not, cost may be a factor when you’re considering Verzenio. What you’ll pay for Verzenio may depend on several things, such as your treatment plan and the pharmacy you use.

Here are a few things to consider regarding cost:

  • Comparing pharmacies: The price of Verzenio may vary depending on which pharmacy you use, so it can help to compare prices across pharmacies to find the lowest cost.
  • Drug coupons: You may be able to find drug coupons on prescription discount websites that can reduce the cost of your medication. These coupons cannot be used with insurance copays or benefits, but the discounted price may be lower than what you would pay through insurance.
  • Financial assistance: Some websites provide details about drug assistance programs, ways to make the most of your insurance coverage, and links to savings cards and other services. Two such websites are:

Here are answers to some commonly asked questions about Verzenio.

How does Verzenio compare with Ibrance?

Verzenio and Ibrance belong to the same group of drugs called kinase inhibitors. And they work in similar ways to stop cancer cells from growing.

Verzenio and Ibrance have a lot in common. But they also have some differences, including how they’re used. Here’s an overview of some of the key differences between Verzenio and Ibrance:

  • Verzenio is approved to treat advanced or metastatic breast cancer and early breast cancer, and Ibrance is only used for advanced or metastatic breast cancer.
  • They contain different active ingredients.
  • Verzenio comes as a tablet, and Ibrance comes as a tablet and a capsule.
  • They come in different strengths.
  • They have some different side effects.
  • Verzenio can be prescribed by itself in certain situations, but Ibrance is used together with other drugs.
  • Verzenio is taken twice per day for as long as it’s prescribed, but Ibrance is taken on cycles of 21 days on, followed by 7 days off for as long as it’s prescribed.

In one study, Verzenio was shown to be helpful when used by itself after other therapies didn’t work. (These other therapies include hormone treatment and chemotherapy.) Ibrance, on the other hand, isn’t used alone when hormone treatments and chemotherapy haven’t worked. Instead, it’s always used with certain other drugs.

Compared with Ibrance, Verzenio causes more stomach and intestinal side effects. These include diarrhea, abdominal pain, and nausea. It can also cause more fatigue. One common side effect of both Ibrance and Verzenio is neutropenia (low level of certain white blood cells). And this condition can increase your risk of serious infections.

If you’d like, your doctor or pharmacist can give you more information on how Ibrance and Verzenio compare with each other.

How does Verzenio affect the life expectancy of someone with breast cancer?

It’s important to know that cancer can affect each person differently. And our bodies can respond differently to various treatments. How your body responds to treatment can depend on things such as:

  • your genetic makeup
  • your overall health and any medical conditions you have
  • your age
  • any medications you may be taking

Survival rate, which is also sometimes called life expectancy, is an estimate of how long someone may live. For people with certain cancers, this estimate is based on everyone who has that kind of cancer. But the estimate doesn’t take into account everyone’s individual factors.

Over the past few years, several new medications, including Verzenio, have shown promise for metastatic breast cancer. They’re improving both survival rates and quality of life in people with this kind of cancer.

Studies have shown that Verzenio increases people’s life expectancy. And the drug slows cancer from spreading in the body when it’s used either alone or together with other medications.

If you’d like to know more about possible outcomes with Verzenio treatment, talk with your doctor.

What’s the effectiveness of Verzenio?

In studies, Verzenio was effective for treating certain kinds of breast cancer. (For more information about this kind of cancer, see the “How is Verzenio used?” section.)

The studies showed that Verzenio was effective when it was used:

In these studies, Verzenio extended the length of time that people’s cancer didn’t spread or worsen. And more people using Verzenio didn’t have their cancer spread or worsen compared with people not using Verzenio.

If you’d like to learn more about how effective Verzenio is, talk with your doctor.

Is it safe to drink coffee while taking Verzenio?

Yes, in most cases it’s safe to drink coffee during Verzenio treatment. Verzenio and coffee aren’t known to interact with each other.

But diarrhea was a common side effect in studies of Verzenio. For some people, coffee may cause or worsen episodes of diarrhea. If you have this side effect after drinking coffee during Verzenio treatment, talk with your doctor. They may recommend that you consume less (or no) coffee to help ease your symptoms.

For more information about Verzenio and coffee, talk with your doctor or pharmacist. You can also read this article to learn more about Verzenio and interactions.

Some important points to discuss with your doctor when considering Verzenio treatment include:

  • your overall health
  • any medical conditions you may have

See the sections below to learn about these and other things to consider before starting this drug.

Interactions

Taking medications, vaccines, foods, and other things with a certain drug can affect how the drug works. These effects are called interactions. Verzenio can interact with some medications, foods, and supplements.

Before taking Verzenio, be sure to tell your doctor about all medications you take (including prescription and over-the-counter types). Also describe any vitamins, herbs, or supplements you use. Your doctor or pharmacist can tell you about any interactions these products may cause with Verzenio.

Interactions with drugs or supplements

Many medications, including Verzenio, are broken down in your liver by an enzyme (type of protein) called CYP3A. This is how the medications get cleared from your body.

Some medications affect how CYP3A works. For instance:

  • CYP3A inhibitors slow the removal of Verzenio from your body. And this can increase your side effects from Verzenio.
  • CYP3A inducers speed up the removal of Verzenio from your body. And this can make Verzenio less effective for you.

Examples of medications that are CYP3A inhibitors include:

Examples of medications that are CYP3A inducers include:

These lists don’t contain all types of drugs that may interact with Verzenio. Your doctor or pharmacist can tell you more about these interactions and any others that may occur with the use of Verzenio.

Other interactions

You should not drink grapefruit juice or eat grapefruit with Verzenio. Doing so can increase the effect of Verzenio in your body. And this may lead to increased side effects of the drug.

Other warnings

Verzenio may not be right for you if you have certain medical conditions or other factors that affect your health. Talk with your doctor about your health history before you take Verzenio. Factors to consider include those in the list below.

Liver or kidney problems: If you have severe liver or kidney problems, your doctor may adjust your dosage of Verzenio. Before you start taking Verzenio, your doctor will order blood work to check the health of your liver and kidneys. And they’ll order these tests during your treatment to make sure your liver and kidneys are working well.

Infection: If you have an infection, your doctor may wait to have you start Verzenio until the infection is treated. This will help you to avoid having complications of the infection.

Blood disorders: Verzenio can lower your blood cell levels. If your blood cell levels are already low, your doctor may have you wait to start Verzenio. This is because it can be dangerous to take the drug while your blood cell levels are low.

Increased risk of blood clots: Verzenio can cause blood clots, which can be life threatening. Verzenio has not been studied in people who have early breast cancer and a history of blood clots. If you have an increased risk of blood clots, such as if you’ve had one in the past, let your doctor know. They’ll determine whether Verzenio treatment is safe for you.

Problems with your immune system: Verzenio may lower the activity of your immune system. And this increases your risk of getting infections. Before you start Verzenio, your doctor will order tests to see how well your immune system is working. And they’ll continue to check on your immune system during your treatment with Verzenio.

Allergic reaction: If you’ve had an allergic reaction to Verzenio or any of its ingredients, you should not take Verzenio. Ask your doctor what other medications are better options.

Verzenio with alcohol

There aren’t any known interactions between Verzenio and alcohol. But alcohol and Verzenio can both affect your liver. If you drink alcohol, be sure to ask your doctor whether it’s safe to drink it while you’re taking Verzenio.

Also, keep in mind that alcohol may increase some side effects with Verzenio, such as:

Pregnancy and breastfeeding

You should not take Verzenio if you’re pregnant or planning to become pregnant. You should also avoid taking this drug if you’re breastfeeding. There isn’t any information available on taking Verzenio during pregnancy or while breastfeeding.

If you have questions about the risks and benefits of using Verzenio during pregnancy or while breastfeeding, talk with your doctor.

Do not take more Verzenio than your doctor prescribes, as this can lead to harmful effects.

What to do in case you take too much Verzenio

Call your doctor if you think you’ve taken too much Verzenio. You can also call 800-222-1222 to reach America’s Poison Centers or use its online resource. But if you have severe symptoms, immediately call 911 or your local emergency number. Or go to the nearest emergency room.
