How quickly do I need to be seen for shingles?
Within 72 hours of the rash appearing — that is the evidence-based window, and the main determinant of outcome is often simply how fast you were seen.
Beyond 72 hours it is still worth treating if the rash is spreading, if you are over 50, or if you are immunosuppressed. Do not assume you have missed the boat.
When is shingles an emergency?
If it affects the eye, eyelid, or the tip of the nose — that needs same-day ophthalmology, not just antivirals.
The nose sign is the one to remember: a rash on the tip of the nose indicates the nerve supplying the eye is involved, and sight is at risk.
Also urgent: facial weakness, hearing change or vertigo with a rash around the ear (Ramsay Hunt syndrome); widespread shingles; or shingles in someone immunosuppressed.
Is shingles contagious?
You cannot give someone shingles — but you can give chickenpox to anyone who has not had it.
Keep the rash covered, and avoid contact with pregnant women who have not had chickenpox, newborns, and anyone immunosuppressed until it has crusted over. It is not spread by coughing.
Will the antivirals get rid of it?
No — these viruses stay dormant in nerve tissue for life, and no treatment eliminates them.
What antivirals do is shorten the episode, reduce its severity, and in shingles reduce the chance of lasting nerve pain. That last point is the main reason to treat.
What is postherpetic neuralgia?
Nerve pain persisting beyond a month after the rash — the commonest complication of shingles, and more likely with increasing age and with severe pain early on.
It is treatable, and it should be reported rather than endured. Early antivirals and early proper pain control both reduce the risk.
Why is paracetamol not touching the pain?
Because shingles pain is neuropathic, and simple painkillers frequently do not work for it. This is routinely undertreated.
Amitriptyline or a gabapentinoid are the appropriate options, and we will be clear about what can be prescribed remotely. We do not prescribe opioids remotely, and they work poorly here anyway.
Should I have the shingles vaccine?
If you are eligible, yes — and it is free on the NHS for eligible age groups and for people who are immunosuppressed.
It substantially reduces both shingles and postherpetic neuralgia, and it is markedly under-taken. Worth checking your eligibility.
My cold sore cream never seems to work.
Timing. Aciclovir cream works only if applied at the tingling stage, before the blister forms — once the blister has appeared it does very little.
If your recurrences are frequent or predictable, having oral treatment in hand to start at the first tingle is far more effective, and worth arranging in advance.
I keep getting outbreaks. Is there anything better?
Yes — suppressive treatment, and it is genuinely under-offered. A daily low dose taken continuously, standard practice for six or more recurrences a year.
It reduces outbreaks substantially and, in genital herpes, reduces transmission to a partner. For people whose life is organised around recurrences, it is transformative.
Can I take these in pregnancy?
They are considered safe where treatment is needed, and this is a discussion worth having rather than avoiding.
Genital herpes in pregnancy needs maternity team involvement, particularly a first episode in the third trimester, which has specific implications for delivery. Tell us.
Are there side effects?
Aciclovir and valaciclovir are well tolerated — most people notice nothing. Nausea, headache and diarrhoea are the commonest.
Two things matter: drink plenty, since these are cleared by the kidneys and can crystallise if you are dehydrated; and doses must be reduced in kidney impairment — at full dose with poor kidney function, confusion and agitation can occur, more often in older people, and it is sometimes mistaken for delirium from the illness itself.
Should I use the NHS for genital herpes instead?
Where you can, yes. NHS sexual health services are free, take self-referrals, and are better placed for partner notification and wider support.
What we offer is speed and privacy when an outbreak starts and you cannot get seen.
