Penicillin Allergy Symptoms: What to Watch For

Immediate vs. Delayed Reactions

Penicillin allergies are typically categorized as immediate or delayed. Immediate reactions occur within an hour of taking the medication and are usually more severe. Delayed reactions can appear days later and are often less serious. Understanding the timing can help determine the type of reaction you're experiencing.

Common Symptoms of Immediate Reactions

Immediate allergic reactions to penicillin can include hives, itching, flushing, swelling of the face or throat, wheezing, difficulty breathing, abdominal pain, nausea, and vomiting. In severe cases, anaphylaxis may occur, causing a dangerous drop in blood pressure and potential loss of consciousness. These symptoms require immediate medical attention.

Delayed Reaction Symptoms

Delayed reactions typically appear after several days of treatment. Common symptoms include rashes, fever, and joint pain. While usually less severe than immediate reactions, some delayed reactions can be serious, such as serum sickness or rare conditions like Stevens-Johnson syndrome.
