Before Using

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of tagraxofusp-erzs injection in children 2 years of age and older. Safety and efficacy have been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of tagraxofusp-erzs injection in the elderly. However, elderly patients are more likely to have unwanted effects (eg, confusion, mental problems, dementia, encephalopathy), which may require caution in patients receiving this medicine.

Breastfeeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Drug Interactions

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.

Other Interactions

Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

Other Medical Problems

The presence of other medical problems may affect the use of this medicine. Make sure you tell your doctor if you have any other medical problems, especially:

  • Heart problems—Use with caution. May cause side effects to become worse.
  • Liver problems—Use with caution. May make this condition worse.

Proper Use

A nurse or other trained health professional will give you this medicine in a medical facility. It is given through a needle placed into one of your veins. This medicine must be given slowly, so the needle will have to stay in place for at least 15 minutes once a day on Days 1 to 5 of a 21-day cycle.

Your doctor may also want you to stay for at least 4 hours to check for unwanted effects.

You may receive other medicines (eg, allergy medicine, fever medicine, steroid, stomach medicine) about 60 minutes before each infusion to prevent unwanted effects.

Precautions

It is very important that your doctor check your or your child's progress at regular visits to make sure this medicine is working properly. Blood and urine tests may be needed to check for unwanted effects.

This medicine may cause a condition called capillary leak syndrome. It can cause fluid to leak from the blood vessels into your body's tissues. Call your doctor right away if you are urinating less often, or have swelling or puffiness, trouble breathing, feeling of fullness, dizziness, or feeling faint. You may also need to weigh yourself daily.

This medicine may cause serious allergic reactions, which can be life-threatening and require immediate medical attention. Tell your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth after receiving this medicine.

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.
