Drug Allergies
Number of Conditions: 5
Penicillin Allergy
Specialty: Allergies and Immunology
Category: Allergic Disorders
Sub-category: Drug Allergies
Symptoms:
hives; swelling; shortness of breath; anaphylaxis in severe cases
Root Cause:
Immune system overreaction to penicillin antibiotics.
How it's Diagnosed: videos
Skin testing for penicillin-specific IgE, clinical history, and sometimes graded oral challenges.
Treatment:
Avoidance of penicillin, alternative antibiotics, antihistamines, corticosteroids, and epinephrine for anaphylaxis.
Medications:
Antihistamines (e.g., Diphenhydramine ), corticosteroids (e.g., Prednisone ), and epinephrine for severe reactions.
Prevalence:
How common the health condition is within a specific population.
Reported by up to 10% of the population, but true allergy is confirmed in only about 1%.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Previous exposure to penicillin, family history of drug allergies.
Prognosis:
The expected outcome or course of the condition over time.
Good with alternative medications; many people outgrow the allergy over time.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Limited antibiotic options, which may lead to suboptimal treatment.
Sulfa Drug Allergy
Specialty: Allergies and Immunology
Category: Allergic Disorders
Sub-category: Drug Allergies
Symptoms:
rash or hives; fever; swelling; difficulty breathing; stevens-johnson syndrome (rare but severe)
Root Cause:
Immune-mediated hypersensitivity to sulfonamide-containing medications.
How it's Diagnosed: videos
Clinical history, exclusion of other causes, and sometimes skin testing.
Treatment:
Discontinuation of sulfa drugs, antihistamines, corticosteroids, and supportive care for severe reactions.
Medications:
Antihistamines (e.g., Cetirizine , Diphenhydramine ) and corticosteroids (e.g., Prednisone ) for severe reactions.
Prevalence:
How common the health condition is within a specific population.
Affects approximately 3% of the population.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
HIV infection, slow acetylator phenotype, and female gender.
Prognosis:
The expected outcome or course of the condition over time.
Good with prompt discontinuation of the drug; severe cases require close monitoring.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Severe reactions like Stevens-Johnson syndrome or toxic epidermal necrolysis.
NSAID Allergy
Specialty: Allergies and Immunology
Category: Allergic Disorders
Sub-category: Drug Allergies
Symptoms:
hives or angioedema; wheezing; nasal congestion; anaphylaxis in severe cases
Root Cause:
Hypersensitivity reaction to NSAIDs caused by immune or non-immune mechanisms.
How it's Diagnosed: videos
Clinical history, oral challenge, and exclusion of other causes.
Treatment:
Avoidance of NSAIDs, use of alternative medications like acetaminophen, and desensitization protocols when necessary.
Medications:
Antihistamines (e.g., Loratadine , Diphenhydramine ) and epinephrine for anaphylaxis.
Prevalence:
How common the health condition is within a specific population.
Affects 0.1-0.3% of the general population.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Asthma, chronic urticaria, nasal polyps.
Prognosis:
The expected outcome or course of the condition over time.
Good with avoidance of offending drugs; severe reactions require emergency preparedness.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Life-threatening anaphylaxis, limited treatment options for pain or inflammation.
Anesthesia Allergy
Specialty: Allergies and Immunology
Category: Allergic Disorders
Sub-category: Drug Allergies
Symptoms:
hives or rash; difficulty breathing; low blood pressure; anaphylaxis
Root Cause:
Immune-mediated reaction or direct histamine release triggered by anesthetic agents.
How it's Diagnosed: videos
Clinical history, perioperative monitoring, skin testing, or specific IgE testing.
Treatment:
Avoidance of the specific anesthetic, preoperative antihistamines or corticosteroids, and epinephrine for anaphylaxis.
Medications:
Epinephrine for severe reactions, corticosteroids (e.g., Hydrocortisone ) for inflammation, and antihistamines (e.g., Diphenhydramine ).
Prevalence:
How common the health condition is within a specific population.
True allergies are rare, estimated at 1 in 10,000 to 1 in 20,000 anesthesia administrations.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Previous surgeries, atopy, and certain medications.
Prognosis:
The expected outcome or course of the condition over time.
Good with appropriate preoperative planning and alternative anesthetic options.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Anaphylaxis, cardiac arrest, or death in rare cases.
Chemotherapy Drug Allergy
Specialty: Allergies and Immunology
Category: Allergic Disorders
Sub-category: Drug Allergies
Symptoms:
hives or rash; swelling; shortness of breath; fever; anaphylaxis
Root Cause:
Hypersensitivity reaction to chemotherapeutic agents due to immune activation or direct mast cell degranulation.
How it's Diagnosed: videos
Clinical history, skin testing, and drug challenge under close supervision.
Treatment:
Premedication with antihistamines or corticosteroids, desensitization protocols, or alternative agents.
Medications:
Premedication with corticosteroids (e.g., Dexamethasone ) and antihistamines (e.g., Diphenhydramine ).
Prevalence:
How common the health condition is within a specific population.
Affects up to 10% of patients receiving chemotherapy, depending on the drug.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Previous exposure to chemotherapy, atopy, female gender.
Prognosis:
The expected outcome or course of the condition over time.
Manageable with premedication or desensitization; alternative drugs may be required in severe cases.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Delayed treatment, anaphylaxis, and therapy-limiting reactions.
