Overview

The types of drugs that can cause drug allergies vary. Drugs containing sulfa are common in causing drug allergy reactions. Other common drugs implicated in leading to an allergic reaction are antibiotics, insulin, and iodinated drugs.

Causes

Common Causes

When a medication causes an allergic reaction, it is called an allergen. The following is a short list of the most common drug allergens

Antibiotics
Analgesics
- Codeine
- Non-steroidal anti-inflammatory drugs (NSAIDs)
Anticonvulsives
- Dilantin
- Tegretol
