What is the most important information I should know about Symjepi?
1. Symjepi contains epinephrine, a medicine used to treat allergic emergencies (anaphylaxis). Anaphylaxis can be life threatening, can happen within minutes, and can be caused by stinging and biting insects, allergy injections, foods, medicines, exercise, or unknown causes. Symptoms of anaphylaxis may include:
- trouble breathing
- hoarseness (changes in the way your voice sounds)
- hives (raised reddened rash that may itch)
- severe itching
- swelling of your face, lips, mouth, or tongue
- skin rash, redness, or swelling
- fast heartbeat
- weak pulse
- feeling very anxious
- stomach pain
- losing control of urine or bowel movements (incontinence)
- diarrhea or stomach cramps
- dizziness, fainting, or “passing out” (unconsciousness)
2. Always carry your Symjepi with you because you may not know when anaphylaxis may happen.
Talk to your healthcare provider if you need additional prefilled syringes to keep at work, school, or other locations. Tell your family members, caregivers, and others where you keep your Symjepi and how to use it before you need it. You may be unable to speak in an allergic emergency.
3. When you have an allergic emergency (anaphylaxis)
- Use Symjepi right away.
- Get emergency medical help right away. You may need further medical attention. You may need to use a second Symjepi if symptoms continue or recur. Only a healthcare provider should give additional doses of epinephrine if you need more than 2 injections for a single anaphylaxis episode.
Other important information
- Your prefilled syringe is designed to work through clothing.
- The needle cap on the Symjepi prefilled syringe helps to prevent needle sticks and accidental injection of epinephrine. Do not remove the needle cap until you are ready to use it.
- Only inject into the middle of the outer thigh (upper leg). Never inject into any other part of the body.
- Never put your thumb, fingers, or your hand over the exposed needle.
- If an accidental injection happens, get medical help right away.
- Do not place patient information or any other foreign objects in the carrier case with the prefilled syringe, as this may prevent you from removing the prefilled syringe for use.
