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

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of piflufolastat F 18 injection in the elderly.

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.

Proper Use

A doctor or other trained health professional will give you this medicine. This medicine is given through a needle placed in one of your veins just before you have a PET scan.

Drink enough water to be hydrated before the PET scan.

You will need to urinate right away and as often as possible for the first few hours after the PET scan.

It is very important that your doctor check you closely while you are receiving this medicine. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to receive it.

This medicine may cause serious allergic reactions, which can be life-threatening and require immediate medical attention. Check with your doctor right away if you have a difficulty in breathing or swallowing, fast heartbeat, skin itching, rash, or redness, or swelling of the face, throat, or tongue after you receive the injection.
