- The antibiotics most commonly associated with allergic reactions are the sulfonamides, penicillins, and cephalosporins. Anaphylaxis is the most severe form of allergic reaction. It can present as an acute, life-threatening reaction with multiple organ system involvement or it can be more localized in appearance. Approximately 1 in every 2,700 hospitalized patients experience drug-induced anaphylaxis. If antibodies are not involved in the process, the reaction is termed anaphylactoid.

- Inflammation is a series of defensive biological reactions to harmful agents that leads to pain, redness, swelling and heat in the affected areas of the body. One notable deadly short-term consequence due in part to the inflammatory response includes anaphylactic shock, which is a severe, potentially deadly, whole-body allergic reaction that occurs with rapid speed.

Delayed hypersensitivity often goes unnoticed because symptoms arise hours or days after ingesting the offending foods.

Medications and Drug Allergic Reactions Most allergic reactions occur within hours to two weeks after taking the medication and most people react to medications to which they have been exposed in the past. This process is called sensitization.. However, rashes may develop up to six weeks after starting certain types of medications. The most severe form of immediate allergic reactions is anaphylaxis (an-a-fi-LAK-sis). Symptoms of anaphylaxis include hives, facial or throat swelling, wheezing, light-headedness, vomiting and shock.
