Penicillin Testing

What is penicillin, and should I get tested for a penicillin allergy? 

Penicillin is a group of antibiotics that’s often prescribed to treat bacterial infections like strep throat, urinary tract infections, and ear infections. It works by targeting the bacterial cell walls, weakening and destroying them.

If you recall having an allergic reaction to penicillin as a child, it’s highly likely you’ve outgrown it. Testing at Allergy Associates of Utah can confirm whether you still need to avoid penicillin or can safely use it again.

What are the symptoms of a penicillin allergy?

If you’re allergic to penicillin, you can experience one, some, or all of these symptoms:

• Itching
• Fever
• Shortness of breath
• Wheezing
• Runny nose
• Hives
• Skin rash
• Gastrointestinal problems
• Headaches

In severe cases, a penicillin allergy could lead to life-threatening anaphylaxis.

Am I a candidate for penicillin testing? 

You’re an ideal candidate for penicillin testing at Allergy Associates of Utah if you:

• Need penicillin for an upcoming medical procedure
• Have a history of allergic reactions after taking penicillin
• Can’t take beta-lactam antibiotics

Your doctor assesses your medical history, talks to you about your past experiences, and evaluates your current medical needs to determine if you can benefit from penicillin testing.

What can I expect during penicillin testing? 

Your doctor places a small amount of penicillin on your skin and lightly pricks the area. If there’s no reaction, you advance to the next round, where you receive a small amount under your skin to test for additional sensitivity. If you still don’t have a reaction, the allergy team will give you an oral dose of penicillin and monitor you closely. 

If you do have an allergic reaction, your skilled provider prioritizes your safety and treats you quickly with antihistamine medication to stop it before it becomes serious or life-threatening. 

A reaction to penicillin earlier in your life does not mean you’re still allergic. Because penicillin is a cost-effective and safe medication, it’s important to determine where you stand with it.
