INTRODUCTION

Introduction

If you have had chickenpox, the varicella-zoster virus is still hiding in your nerve roots. When immunity dips, it reactivates as shingles—tingling followed by a sharply demarcated band of blisters and stabbing pain.

One in three people will experience shingles. Acting within 72 hours is the difference between a short-lived rash and months of post-herpetic neuralgia.

WHAT IS SHINGLES?

What Is Shingles?

Shingles is a reactivation of varicella-zoster virus along a single dermatome. It is unilateral, blistering, and intensely painful compared with chickenpox. Immunosenescence, stress, chemotherapy, and poorly controlled diabetes all raise your risk.

CAUSES & SYMPTOMS

Causes & Symptoms

The illness progresses through prodrome, blistering phase, and healing. Burning or itching precedes the rash by a few days, then vesicles emerge, crust, and heal over 2–4 weeks.

Watch for:

  • Band-like clusters of vesicles on one side of the body or face
  • Severe neuritic pain (burning, electric shocks)
  • Low-grade fever or fatigue during the acute phase
  • Persistent nerve pain (post-herpetic neuralgia) in older adults

TREATMENT & PHARMACY SUPPORT

Treatment & Pharmacy Support

Pharmacists provide scheduled analgesia plans, topical lidocaine patches, wound-care advice, and guidance on antiviral adherence once your GP prescribes aciclovir, valaciclovir, or famciclovir.

We will also discuss:

  • Why antivirals must begin within 72 hours to reduce complications
  • How to layer paracetamol, ibuprofen, or capsaicin after vesicles crust
  • Hydration and renal protection while taking high-dose antivirals
  • Eligibility for the state-funded Shingrix vaccine once you are recovered

RED FLAGS

Red Flags

Seek emergency ophthalmic or hospital review if:

  • Rash or pain involves the eye, forehead, or tip of the nose (risk of corneal damage)
  • You notice facial weakness, hearing changes, or vertigo (possible Ramsay Hunt syndrome)
  • You are immunocompromised and the rash is widespread or crosses the midline
  • Pain is uncontrollable or you develop meningitis-like symptoms (headache, neck stiffness)

PLAN YOUR RECOVERY

Plan Your Recovery

Tell your pharmacist as soon as you suspect shingles so we can fast-track GP referral for antivirals, manage the pain aggressively, and schedule the Shingrix vaccine once you heal.
