1. Introduction

Medications, both prescription and over-the-counter, can sometimes cause side effects, and the skin is a common site for these reactions. Skin changes due to medication side effects can range from mild to severe and may manifest in various ways. Understanding these potential reactions is important for anyone taking medication.

2. Common Skin Changes Due to Medications

Several types of skin changes can occur as a result of taking medication:

• Rash: This is one of the most common reactions and can be caused by many medications, including aspirin and antibiotics. (MyHealth Alberta)
• Hives (Urticaria): These are raised, swollen, red or flesh-colored bumps or welts on the skin that can be very itchy. They can appear anywhere on the body and may cover large areas. (NYU Langone Health)
• Itching (Pruritus): Itching can occur with or without a visible rash and is a frequent symptom of drug reactions. (BMJ Best Practice)
• Skin Color Changes: Some medications, such as birth control pills, can cause changes in skin pigmentation. 
• Blisters: Some drug reactions can cause the formation of blisters on the skin.

3. Types of Drug-Induced Skin Reactions

Drug-induced skin reactions can manifest in various forms, including: (BMJ Best Practice)

• Maculopapular eruptions (flat, red areas with small bumps)
• Fixed drug eruptions (rashes that reappear in the same spot with each exposure to the drug) 
• Erythema multiforme (target-like lesions) 
• Drug reaction with eosinophilia and systemic symptoms (DRESS syndrome), also called drug hypersensitivity syndrome (severe reaction with fever, rash, and internal organ involvement) 
• Stevens-Johnson syndrome and toxic epidermal necrolysis (severe blistering and peeling of the skin) 

4. Managing Skin Changes from Medications

If you experience skin changes while taking medication, here are some steps to take:

• Identify the Medication: Note the name and dosage of all medications you are currently taking, including over-the-counter drugs and supplements.
  
  
  
• Stop Non-Prescription Medications: If you suspect a non-prescription medicine is causing the reaction, stop taking it and monitor your symptoms. (MyHealth Alberta)
  
  
  
• Seek Medical Advice: Contact the doctor who prescribed the medication as soon as possible to inform them about the skin changes. They can advise whether you should stop taking the medication or switch to an alternative.
  
  
  
• Manage Symptoms: While waiting for medical advice, you can try applying cool compresses, using over-the-counter antihistamines for itching, and avoiding scratching the affected area. (Penn Medicine Becker ENT)

5. When to Seek Medical Advice

Seek immediate medical attention if you experience any of the following severe symptoms:

• Difficulty breathing or swallowing
• Swelling of the face, lips, or tongue
• Widespread rash or hives
• Blistering or peeling skin
• Fever

6. Q&A

Q: Can over-the-counter medications cause skin reactions?
A: Yes, even non-prescription medications like aspirin can cause skin reactions in some people.

Q: How are drug-induced skin reactions treated?
A: Treatment depends on the type and severity of the reaction. Mild reactions may resolve on their own after stopping the medication or can be treated with topical creams or oral antihistamines. Severe reactions may require hospitalization and medications like epinephrine or corticosteroids.

Q: Will a drug allergy rash always reappear if I take the medication again?
A: In many cases, yes. Once you have a drug allergy rash, your body will likely react again if you take the same medication. It's important to inform your doctor about any drug allergies you have experienced.
