What Is This medicine?
Put simply, perflutren protein-type a microspheres injection is a specialized contrast agent. If you wonder what a contrast agent is, think about turning on a flashlight in a dark room to see objects clearly. That is very similar to how this medicine functions inside your body.
When your doctor performs an ultrasound scan of your heart, this medicine helps highlight the inside structures and blood flow patterns. It allows your doctor to see your heart chambers and blood vessels with exceptional clarity. Ultimately, this helps your medical team spot any heart abnormalities or issues accurately.
You might encounter this medicine under brand names such as Definity, Definity RT, or Optison. All of these brand names refer to the same type of contrast product used for imaging procedures.
The most important thing to remember is that this medicine does not treat or cure a disease. doctors use it purely for diagnostic purposes to help figure out what is happening inside your heart.
Doctors may sometimes use this medicine for other clinical reasons not listed here. If you have questions about why you need this scan, always ask your doctor or pharmacist for clear guidance.
What Should I Tell My Care Team Before I Take This medicine?
Before you receive your perflutren protein-type a microspheres injection, you must inform your doctor, nurse, or medical team about several important health details. Sharing this information keeps you safe throughout the procedure.
First, tell your care team if you have any existing heart conditions. If you already suffer from a heart problem, your medical team needs to know how this medicine might interact with your specific condition.
Second, let your team know if you have any allergies. This is a critical step. Ask yourself these questions:
- Have you ever experienced an allergic reaction to perflutren, albumin (a type of protein), or blood products in the past?
- Do you have allergies to other medicines, foods, artificial dyes, or chemical preservatives?
Never hesitate to mention even small allergies. Allergic reactions can be serious, so your medical team needs accurate information before proceeding.
- Pregnancy and breastfeeding: If you are pregnant, planning to become pregnant, or currently breastfeeding your baby, you must inform your doctor right away so they can determine if this test is appropriate for you at this time.
Giving your doctor a complete health history ensures that your care team can give this diagnostic procedure as safely as possible.
