to remember

What is CAMZYOS?

CAMZYOS is a prescription medicine used to treat:

adults with symptomatic obstructive hypertrophic cardiomyopathy  (obstructive HCM). CAMZYOS may improve your symptoms and your ability to be active.

It is not known if CAMZYOS is safe and effective in children.

WARNING: RISK OF HEART FAILURE

 

CAMZYOS may cause serious side effects, including heart failure.

Heart failure, a condition where the heart cannot pump with enough force, is a serious condition that can lead to death.

You must have echocardiograms before you take your first dose and during your treatment with CAMZYOS to help your healthcare provider understand how your heart is responding to CAMZYOS.  Echocardiograms (echos) are imaging tests, a type of ultrasound study, which take pictures of your heart and show how well your heart is working.

People who develop a serious infection or irregular heartbeat have a greater risk of heart failure during treatment with CAMZYOS.

Get medical help right away if you experience new or worsening symptoms, including:
  • shortness of breath
  • chest pain
  • fatigue
  • racing heart (palpitations)
  • leg swelling
  • rapid weight gain

The risk of heart failure is also increased when CAMZYOS is taken with certain other medications. Tell your healthcare provider about the medicines you take, both prescribed and obtained over-the-counter, before and during treatment with CAMZYOS.

Because of the serious risk of heart failure, CAMZYOS is only available through a restricted program called the CAMZYOS Risk Evaluation and Mitigation Strategy (REMS) Program. This means:

You and your healthcare provider must both be enrolled in the CAMZYOS REMS program in order to have it prescribed. Talk to your healthcare provider about how to enroll and for more information about the program.

Your healthcare provider and pharmacist will make sure you understand how to take CAMZYOS safely, which includes returning for echos when advised by your healthcare provider.

You can get CAMZYOS only from a certified pharmacy that is part of the CAMZYOS REMS program. Talk to your healthcare provider about finding a certified pharmacy. You will not be able to get CAMZYOS from a local pharmacy.

If you have questions about the CAMZYOS REMS program, ask your healthcare provider, visit www.CAMZYOSREMS.com or call 1‑833‑628‑7367.

What should I discuss with my healthcare provider before starting CAMZYOS?

Talk to your healthcare provider about  all of your medical conditions, including if:

CAMZYOS may reduce how well some hormonal birth control works. Talk to your healthcare provider about the use of effective forms of birth control during treatment with CAMZYOS.
