Step-by-Step: Diagnosing Drug-Induced Skin Reactions
Published: Oct 12, 2023
Diagnosing skin reactions from drugs can be tricky. Let's walk through the steps to help identify the source and find relief.
Initial Assessment
Start by gathering a thorough medication history from the patient, including any recent changes in their prescriptions or over-the-counter drugs. Note the timing of when the skin reaction appeared in relation to medication use. This initial step is crucial to narrowing down potential culprits.
Examining the Rash
Observe the rash's characteristics, such as its size, shape, and location on the body. Common patterns include exanthematous eruptions, which look like measles, or more severe reactions like blistering. Documenting these details helps differentiate between various types of drug reactions.
Using Diagnostic Tools
In some cases, additional diagnostic methods like skin biopsies or patch tests may be necessary. These tests can provide more information about the rash and confirm if a drug is the cause. Always consult with a dermatologist for complex cases.
