Shingles in Ireland — Treatment and Vaccine Guide

What is shingles?

Shingles (medical name herpes zoster) is a painful rash caused by reactivation of the chickenpox virus (varicella-zoster virus), which stays dormant in nerve cells after the original chickenpox infection. Most common in older adults — risk increases sharply from age 50. About 1 in 4 people will have shingles in their lifetime per HSE estimates.

Symptoms

Typically per NICE CKS:

• Tingling, burning, or pain in a band on one side of the body — usually 1-5 days before any rash
• Rash: red patches, then fluid-filled blisters in the same band/strip; classic feature is staying on one side of the body and not crossing the midline
• Blisters crust over within 7-10 days
• Pain can be severe and continue beyond the rash
• Fatigue, headache, mild fever sometimes accompany the early phase

Treatment — timing matters

Per NICE and ICGP, oral antiviral therapy (aciclovir, valaciclovir, famciclovir) is most effective when started within 72 hours of rash onset. Antivirals shorten the illness, reduce pain severity, and reduce the risk of postherpetic neuralgia (persistent nerve pain after the rash heals). Treatment is still often recommended after 72 hours in older adults, immunocompromised patients, or those with severe symptoms.

Pain management ranges from paracetamol/NSAIDs through to nerve-pain agents (amitriptyline, gabapentin, pregabalin) for postherpetic neuralgia. Topical capsaicin or lidocaine patches can help.

When to seek urgent in-person care

• Shingles near the eye (herpes zoster ophthalmicus) — rash on the forehead, eyelid, or nose tip with eye redness or pain. Needs same-day in-person assessment, often ophthalmology referral. Untreated can threaten vision.
• Widespread rash crossing the midline or affecting multiple regions
• Immunocompromised patients
• Pregnant women
• Severe pain not controlled by simple analgesia
• Signs of secondary infection — increasing redness, pus, fever

Shingrix vaccine

The Shingrix vaccine (recombinant zoster vaccine) is highly effective — around 90% efficacy at preventing shingles and reducing postherpetic neuralgia. Per HSE National Immunisation Office:

• Recommended for adults aged 50 and over
• Two doses given 2-6 months apart
• Particularly recommended for those at higher risk (older adults, immunocompromised)
• Currently typically available privately in Ireland (Shingrix is not part of the routine HSE programme for general population at time of writing — check current HSE/NIO eligibility, which is evolving)
• Available through pharmacies and travel/private health clinics

Important: avoid Shingrix during active shingles or for 12 months after an episode. Discuss with your Online Doctor or treating doctor for personal eligibility.

Is shingles contagious?

Yes — but differently from chickenpox. People who have never had chickenpox or are unvaccinated can catch chickenpox from someone with shingles (not shingles itself), through direct contact with the rash. Cover the rash with clothing or a dressing. Avoid pregnant women who have not had chickenpox, immunocompromised people, and newborns until the rash crusts.

Online Doctor consultation

Helpful for: prompt antiviral prescription within the critical 72-hour window, pain management, vaccine discussion, and follow-up. For eye involvement, atypical presentation, or severe disease, in-person assessment is appropriate.
