Allergic Reactions

Allergic reactions can be caused by foods, insect stings, medications, pollen or other substances. Although most allergic reactions are not serious, severe reactions can be life threatening, requiring immediate medical attention.

Common symptoms can be considered mild or severe, and include:

Mild Symptoms:

  • Skin redness
  • Itchiness
  • Slight swelling
  • Stuffy or runny nose
  • Sneezing
  • Itchy or watering eyes
  • Red bumps (hives) anywhere on the body

Severe Symptoms:

  • Swelling of the tongue or mouth
  • Difficulty swallowing or speaking
  • Wheezing or difficulty breathing
  • Abdominal pain, nausea, vomiting or diarrhea
  • Dizziness or fainting


Contact your physician or visit Jupiter Medical Center’s Urgent Care Center if the reaction is more than mild, or concerns you. With mild symptoms, give an oral antihistamine. If symptoms are severe and you have an injectable epinephrine (EpiPen), immediately use it as directed and call for emergency medical help.


Avoid substances that are known to cause an allergic reaction. Keep oral antihistamines on hand. If you have severe allergies and have a physician prescribed injectable epinephrine, keep it nearby at all times. Make sure you know how to use it properly.
