What is Palforzia?
Palforzia is used to help reduce the severity of an allergic reaction (including anaphylaxis) when you are accidentally exposed to peanuts. This medicine will not treat an allergic reaction that has already begun.
Palforzia is for use in adults and children at least 4 years old who have been diagnosed with an actual peanut allergy. Palforzia will not affect allergic reactions to other foods. Always seek emergency medical attention if you have an allergic reaction.
Palforzia is available only under a special program. You must be registered in the program and understand the risks and benefits of this medicine.
You should not use Palforzia if you have uncontrolled asthma, or problems with your esophagus or digestive tract due to increased eosinophils (a type of white blood cell).
Palforzia can cause a severe or life-threatening allergic reaction. Your doctor may prescribe epinephrine injection to keep on hand in case you have an allergic reaction.
Call your doctor or get emergency medical help if you have an allergic reaction, even if you have used epinephrine to treat it.
Before taking this medicine
You should not use Palforzia if you have:
untreated or uncontrolled asthma; or
problems with your esophagus or digestive tract that are caused by higher than normal levels of eosinophils (a type of white blood cell).
You may not be able to use Palforzia if:
you are unable to give yourself an epinephrine injection in the case of an allergic reaction; or
an allergic reaction would be life-threatening to you because of a medical condition you have or a medicine you use.
To make sure Palforzia is safe for you, tell your doctor if you have:
any disease related to increased eosinophils.
Tell your doctor if you are pregnant or breastfeeding.
How should I take Palforzia?
Take Palforzia exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.
When you start using Palforzia (and any time your dose is increased) you will receive your first dose in a hospital or clinic setting. Your breathing, blood pressure, oxygen levels, and other vital signs will be watched closely for at least 60 minutes after your dose.
Your dose may need to be postponed if you are not feeling well before starting this treatment.
Do not swallow a Palforzia capsule whole or inhale the powder medicine. Open the capsule or powder packet and sprinkle the medicine into a spoonful of applesauce, yogurt, or pudding (do not mix with liquid). Stir well and swallow the mixture right away without chewing. Do not save it for later use.
You may need to use up to 6 capsules to get the correct dose. Follow your doctor's dosing instructions very carefully.
Wash your hands after handling a capsule or powder packet.
You may be more likely to have an allergic reaction:
if you have uncontrolled asthma;
if you are sick with a virus;
during your menstrual period;
during vigorous exercise or exposure to hot water;
if you are not getting enough sleep;
if you are not getting enough to eat; or
if you are taking an NSAID (nonsteroidal anti-inflammatory drug).
The timing of your doses may need to be adjusted to avoid using Palforzia while any of the above conditions exists.
Store Palforzia in the original packaging in a refrigerator, do not freeze.
You must keep injectable epinephrine with you at all times while you are using Palforzia. Read and carefully follow any Instructions for Use provided with your epinephrine. Ask your doctor or pharmacist if you don't understand all instructions.
