Overview of Allegra

Allegra is an antihistamine medication commonly used to alleviate symptoms associated with seasonal allergies. The medication is effective in reducing common symptoms like sneezing, runny nose, and itchy eyes. Allegra works by blocking histamine, a substance in the body responsible for triggering allergic reactions. By inhibiting histamine, Allegra helps to alleviate allergy symptoms and provide relief to individuals suffering from seasonal allergies.

Types of Drug Allergies

Immediate Allergic Reactions

Immediate allergic reactions are the most common type of drug allergy and occur within minutes to hours after taking the medication. Symptoms can range from mild itching and hives to more severe reactions like anaphylaxis. An example of this type of drug allergy is a rash developed after taking penicillin.

Delayed Allergic Reactions

Delayed allergic reactions to drugs can occur days to weeks after exposure to the medication. Symptoms may include skin rashes, fever, and joint pain. A classic example is a delayed hypersensitivity reaction to sulfa drugs, which can manifest as a skin eruption.

Cytotoxic Reactions

Cytotoxic reactions involve the formation of antibodies that attack the body’s own cells after exposure to a drug. This can lead to conditions like hemolytic anemia, where red blood cells are destroyed. Methyldopa is an example of a medication that can cause a cytotoxic reaction.

Immune Complex Reactions

Immune complex reactions occur when antibodies and antigens form immune complexes that deposit in tissues, leading to inflammation and tissue damage. Drug-induced immune complex reactions can result in conditions like serum sickness. A well-known medication associated with immune complex reactions is penicillin.

Types of Drug Allergies and Prevalence

The survey also revealed the prevalence of different types of drug allergies:

  • Immediate allergic reactions: These occur within minutes to a few hours after taking a medication and account for 80% of drug allergies.

  • Cytotoxic reactions: These reactions involve the body’s immune system attacking its own cells in response to a drug, representing 5% of drug allergies.

Impact of Drug Allergies on Healthcare Costs

The survey also highlighted the financial burden of drug allergies, with an estimated $2-4 billion spent annually in the US on clinical services related to drug allergies. These costs encompass physician visits, emergency department visits, hospitalizations, and medications to manage allergic reactions.

Recommendations for Managing Drug Allergies
