Shingles Rash: Why the First 72 Hours Matter
A band of burning, stabbing pain on one side of the body, followed by a strip of red blisters that stops at the midline — that’s the classic picture of shingles. Antiviral tablets work best when started within 72 hours of the rash appearing, cutting the severity and the risk of long-lasting nerve pain. That deadline is exactly why a same-day video review with a registered Irish doctor (€34.99) is worth booking now, not next week.

Recognising shingles
- Pain first — burning, tingling or stabbing in one area, often 1–3 days before anything appears on the skin.
- One-sided rash — a band or patch of red spots turning to fluid-filled blisters, most often on the chest, back or abdomen, never crossing the midline.
- Blisters cloud, burst and crust over 7–10 days; the rash usually clears within 2–4 weeks.
- You can feel generally off — headache, fatigue, mild fever.
Shingles is the chickenpox virus reactivating from where it lay dormant in a nerve — anyone who has had chickenpox can get it, and it becomes more common (and harsher) from the 50s onward, or when the immune system is run down.
Treatment
- Antiviral tablets (aciclovir or valaciclovir, typically 7 days) — most effective started within 72 hours of the rash, and particularly recommended over 50, with moderate-to-severe rash or pain, or with any complication risk. Beyond 72 hours they can still be worthwhile while new blisters are appearing.
- Proper pain relief — shingles pain is nerve pain; paracetamol may not be enough, and the doctor can prescribe targeted options where needed.
- Skin care — keep the rash clean and dry, loose clothing, a cool compress; cover weeping blisters lightly.
Am I contagious?
You cannot give anyone shingles — but the fluid in the blisters can give chickenpox to someone who has never had it. Until every blister has crusted: keep the rash covered, avoid sharing towels, and stay away from pregnant women who haven’t had chickenpox, newborns, and anyone immunosuppressed. Covered and dry, everyday work and contact is generally fine.
How the online consultation works
- Book a time above — same-day appointments are usually available, seven days a week.
- Show the rash by video — its one-sided banded pattern is usually diagnostic on camera.
- Get treated fast — antivirals and pain relief prescribed electronically to your pharmacy where appropriate, plus clear guidance on contagion and red flags.
Frequently asked questions
What does shingles feel like at the start?
Usually pain before rash: burning, tingling or stabbing in one patch of skin for one to three days, then red spots and blisters appear in that same area on one side of the body only.
Why do the first 72 hours matter?
Antiviral tablets shorten the illness and reduce the risk of lasting nerve pain most effectively when started within 72 hours of the rash appearing — after that the benefit falls, though treatment can still help while new blisters are forming.
Can I give shingles to someone?
Not shingles itself — but blister fluid can cause chickenpox in someone who’s never had it. Keep the rash covered until fully crusted, and avoid non-immune pregnant women, newborns and immunosuppressed people.
Can I work with shingles?
If you feel well enough and the rash can be kept covered and dry, generally yes — unless you work with high-risk groups (maternity, neonatal, immunosuppressed patients), where you should stay off until crusted. A sick note can be arranged during the consultation if needed.
Shingles is near my eye — is that serious?
Potentially, yes. Shingles on the forehead, around the eye or on the tip of the nose can involve the eye itself and threaten sight — it needs same-day in-person assessment, usually with an eye specialist, rather than a remote consultation alone.
Can you get shingles more than once?
Yes, though most people don’t. Repeated episodes, or shingles at a young age, are worth discussing — occasionally they point to a run-down immune system, and vaccination may be worth considering.
