Allopurinol: Key Points and Mnemonics

Introduction

• Presenter: Claire
• Topic: Allopurinol, a medication for preventing gout.
• Focus for NCLEX: Mechanism, usage, and side effects of Allopurinol.
• Mnemonic Anchor: Aloe plant, due to phonetic similarity to allopurinol ("allo").

Mechanism and Usage

• Primary Function: Lowers uric acid levels.
• Mnemonic Symbol: Yurt + acidic lemons = uric acid.
• Clinical Uses:
  • Gout Prevention:
    • Used for maintenance therapy to prevent gouty attacks.
    • Not for treating acute gout attacks (use NSAIDs for that).
    • Reduces uric acid buildup in joints, preventing attacks.
  • Kidney Stone Prevention:
    • Useful in preventing uric acid kidney stones in gout patients.

Patient Advice

• Hydration:
  • Patients should take allopurinol with plenty of water.
  • Increased water intake helps prevent uric acid crystallization, reducing gout and kidney stones risk.

Tumor Lysis Syndrome

• Mnemonic Symbol: Crab = Cancer (Zodiac symbol).
  • Split Crab: Symbolizes tumor lysis syndrome.
• Context:
  • Happens when chemotherapy causes rapid cancer cell death, increasing uric acid levels.
  • Allopurinol is used to manage uric acid in tumor lysis syndrome.

Side Effects

• Mnemonic Symbol: Scrapes from aloe plant = rash.
  • Potential Rash: Allopurinol can cause a severe rash known as Stevens-Johnson syndrome.
  • Patient Instructions: Report any rash immediately due to the severity of Stevens-Johnson syndrome.
