Important Safety Information

There are three main risks associated with treatment with CAMZYOS:

• Heart failure due to systolic dysfunction, a condition where the heart cannot pump enough blood to the body.
• Heart failure due to interactions with certain medicines and herbal supplements.
• Embryo-fetal toxicity (toxicity to an unborn baby).

Other possible side effects related to CAMZYOS are outlined in the patient leaflet.

CAMZYOS and heart failure

Heart failure due to systolic dysfunction is a serious medical condition that sometimes can lead to death.

Tell your prescriber or doctor, or seek other medical attention immediately if you experience new or worsening symptoms of heart failure, including shortness of breath, chest pain, fatigue, swelling in your legs, a racing sensation in your heart (palpitations), or rapid weight gain.

Tell your prescriber or doctor of any new or existing medical condition(s) you experience before and during treatment with CAMZYOS. Certain conditions, such as infections or atrial fibrillation (irregular and rapid heartbeat), may impact your treatment with CAMZYOS.

CAMZYOS and drug interactions

Some medicines, including those available over-the-counter, and some herbal supplements can affect the levels of CAMZYOS in your body and may increase the risk of heart failure due to systolic dysfunction. Tell your prescriber, doctor or pharmacist about all the prescription medicines, over-the-counter medicines and herbal supplements you take, even if you do not take them every day. Do not start taking, stop taking or change the dose of any of your medicines, vitamins or herbal supplements without consulting your prescriber, doctor or pharmacist.

Some examples of medicines and products that may affect how much CAMZYOS is in your body are shown in Table 1. Please note, these examples are a guide and are not considered a comprehensive list of all possible medicines that may fit this category. Intermittent use of products that might affect the levels of CAMZYOS in your body, including prescription and over-the-counter medicines, vitamins, herbal supplements and grapefruit juice, is not recommended.

CAMZYOS and embryo-foetal toxicity (toxicity to unborn baby)

If you are pregnant or plan to become pregnant, consult your doctor before starting treatment with CAMZYOS. CAMZYOS may harm your unborn baby.

If you are able to get pregnant, you will need a confirmed negative pregnancy test before you start taking CAMZYOS. You should use an effective method of contraception throughout treatment with CAMZYOS and for 4 months after your last dose of CAMZYOS. CAMZYOS may reduce how well some hormonal birth control works.  You should discuss with your doctor which method(s) of contraception is/are the most suitable for you.

Talk to your doctor if you are considering becoming pregnant. If you suspect you may be pregnant or are pregnant while receiving CAMZYOS, tell your prescriber or doctor immediately. Your prescriber or doctor will discuss your treatment options with you.
