Does A Penicillium Mold Allergy Mean I'm Allergic to Penicillin Antibiotics?
The positive allergy test to Penicillium mold mix means that you have an allergy to a common indoor mold called Penicillium. This mold can cause allergies and asthma in some people who are more sensitive to these mold spores in the air.
Having a penicillium mold allergy does not mean that you are allergic to Penicillin antibiotics, such as Amoxicillin and Augmentin. While Penicillin was originally developed from mold, people with this specific mold allergy are not at a higher risk of developing an allergy to penicillin-based antibiotics, compared to anyone else with allergies.
Finally, modern-day Penicillin antibiotics are produced synthetically and are not contaminated with mold particles.
