Apalutamide

Apalutamide

(a' puh loo" tuh mide)

Brand Name(s): , Erleada®


WHY is this medicine prescribed?

Apalutamide is used to treat certain types of prostate cancer (cancer that begins in the prostate [a male reproductive gland]) that has not spread to other parts of the body in men who have not been helped by other medical treatments. Apalutamide is in a class of medications called androgen receptor inhibitors. It works by blocking the effects of androgen (a male reproductive hormone) to stop the growth and spread of cancer cells.

Are there OTHER USES for this medicine?

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

HOW should this medicine be used?

Apalutamide comes as a tablet to take by mouth. It is usually taken with or without food once a day. Take apalutamide at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take apalutamide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the tablets whole; do not split, chew, or crush them.

Your doctor may tell you to stop taking apalutamide for a short time or decrease your dose if you experience serious side effects during your treatment. Be sure to talk to your doctor about how you are feeling during your treatment with apalutamide.

If your doctor has prescribed another medication such as goserelin (Zoladex), histrelin (Supprelin LA, Vantas), leuprolide (Eligard, Lupron), or triptorelin (Trelstar) to treat your prostate cancer, you will need to continue receiving this medication during your treatment with apalutamide.

Continue to take apalutamide even if you feel well. Do not stop taking apalutamide without talking to your doctor.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

What SPECIAL PRECAUTIONS should I follow?

Before taking apalutamide,

  • if your partner is pregnant, you must use a condom whenever you have sex during your treatment with apalutamide and for three months after your final dose.

What should I know about STORAGE and DISPOSAL of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from light, excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. [WEB]

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ([WEB]) for more information if you do not have access to a take-back program.

What should I do in case of OVERDOSE?

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at [WEB]. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.

What OTHER INFORMATION should I know?

Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body's response to apalutamide.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
