Shingles
Also called: herpes zoster, zoster
A painful, blistering rash caused by the chickenpox virus reactivating. BC pharmacists can assess shingles and prescribe antiviral treatment, which works best when started early.
Quick answer
- What it is
- Shingles is a reactivation of the varicella-zoster virus — the virus that causes chickenpox — which stays dormant in the nerves after a chickenpox infection and can wake up years later.
- Common symptoms
- Burning, tingling or pain on one side of the body, followed a few days later by a band or patch of fluid-filled blisters in the same area.
- How it's treated
- Antiviral tablets, ideally started within 72 hours of the rash appearing, along with pain relief and keeping the rash clean and covered.
- Who can help
- Shingles is on the list of conditions BC pharmacists can assess and prescribe for — Pill4Me can see you the same day, no doctor's appointment needed.
- Warning signs
- A rash on the forehead, around the eye or on the tip of the nose, any change in vision, a rash spreading across the body, or a weakened immune system all need prompt medical assessment.

Book a pharmacist assessmentWhat is shingles?
Anyone who has had chickenpox can get shingles. The virus never fully leaves the body; it rests in nerve cells and can reactivate, most often in people over 50 or when the immune system is weakened by illness, medication or stress. Because it follows a single nerve, the rash usually appears as a band or strip on one side of the body or face and does not cross the midline.
Timing matters. Antiviral medication shortens the outbreak and can reduce the risk of long-lasting nerve pain afterwards, but it works best when started within about 72 hours of the rash appearing. That is why waiting for a doctor's appointment can cost you the most useful window — and why a same-day pharmacist assessment helps.
Shingles itself is not caught from someone else, but fluid from the blisters can give chickenpox to a person who has never had chickenpox or the vaccine. Keeping the rash covered until it crusts over protects babies, pregnant people and anyone with a weakened immune system around you.
Common symptoms
Shingles usually develops in stages:
- Burning, tingling, itching or stabbing pain in one area, often a day to a few days before any rash
- A red rash in a band or patch on one side of the body or face
- Fluid-filled blisters that break open and then crust over within 7 to 10 days
- Sensitivity to touch over the affected area
- Sometimes fever, headache, tiredness or feeling generally unwell
Having these symptoms does not confirm a diagnosis — they overlap with other conditions. Assessment by a pharmacist, physician or nurse practitioner is what establishes the cause.
Causes and risk factors
What causes it
- Reactivation of the varicella-zoster virus, which stays in the body after chickenpox
- A weakening of the immune response that normally keeps the virus dormant — most often with age
What raises the risk of developing it
- Being over 50
- A weakened immune system from conditions such as cancer or HIV
- Medications that suppress the immune system, including long-term steroids and transplant medications
- Significant physical or emotional stress
- Having had chickenpox — shingles cannot occur without a previous infection or the live vaccine
Risk factors make a condition more likely across a population — they are not causes, and having several does not mean you will develop it.
When should I seek medical care?
Seek urgent or emergency care
- Rash on the forehead, around the eye or on the tip of the nose, or any eye pain or change in vision — the eye can be permanently damaged
- Weakness or drooping on one side of the face, or hearing changes
- Severe headache, stiff neck, confusion or high fever
- Rash spreading widely across the body
If you are unsure how urgent something is, call 8-1-1 to speak with a HealthLink BC nurse at any hour, or 911 in an emergency.
Worth asking a pharmacist
- A painful one-sided rash or blisters that look like shingles in an otherwise healthy adult
- Rash that started within the last few days, so antiviral treatment can begin early
- Advice on pain relief and caring for the rash
- Questions about the shingles vaccine
See a physician or nurse practitioner
- Shingles in someone with a weakened immune system or on immune-suppressing medication
- Shingles during pregnancy, or in a child
- A rash that keeps spreading, or blisters in several areas of the body
- Pain that continues for weeks after the rash has healed
- Signs the rash has become infected — spreading redness, warmth, pus or increasing pain
How is shingles treated?
Lifestyle measures
- Keep the rash clean, dry and loosely covered until the blisters crust over
- Cool, damp compresses and loose clothing can ease discomfort
- Avoid contact with babies, pregnant people and anyone with a weakened immune system who has not had chickenpox until the rash has crusted
- Try not to scratch or break blisters, which can lead to infection and scarring
Medication
Antiviral tablets are the main treatment and work best when started within 72 hours of the rash appearing. Which antiviral and for how long depends on your kidney function, other medications and medical history, so the choice is made at assessment. Pain relief — from over-the-counter options to prescription medication for more severe pain — is an important part of treatment.
Monitoring
Most shingles outbreaks heal within two to four weeks. If the rash spreads, becomes infected, or nerve pain persists after the skin has healed (post-herpetic neuralgia), see a physician. Once you have recovered, ask about the shingles vaccine, which reduces the chance of another episode.
This is a general overview, not a treatment plan. What is right for you depends on your history, your other conditions and everything else you take — that is a conversation with your prescriber or pharmacist.
Can a BC pharmacist assess shingles?
Yes — this is within pharmacist scope in BC
Shingles (herpes zoster) is on the list of conditions BC pharmacists can assess and prescribe for under the Minor Ailments and Contraception Service. A pharmacist at Pill4Me can look at the rash, and where it is appropriate, prescribe and dispense antiviral treatment the same day — no doctor's appointment needed.
Important limits and when you will be referred
- Any rash near the eye or on the tip of the nose needs urgent physician or emergency assessment, not pharmacist treatment
- You will be referred to a physician if you are pregnant, if the patient is a child, if your immune system is weakened, or if the rash is widespread
- Antivirals are most effective within 72 hours of the rash appearing — come in as soon as you can
- If pain is severe or the rash is not healing as expected, you will be referred for follow-up
