Cold sores (herpes labialis) are small, fluid-filled blisters that form on or around the lips, caused by the herpes simplex virus that stays dormant in the body between flare-ups. Many people notice a tingling, itching, or burning sensation hours to a day before a blister actually appears -- that early warning sign is often the best moment to start treatment. Common triggers include sun exposure, stress, illness, fatigue, or hormonal changes, and once you've had one cold sore, recurrences are common because the virus never fully leaves the body.

Quick Self-Check
Answer a few quick questions. This isn't a diagnosis — a real pharmacist assessment is the next step either way.
How We Work
Because cold sores respond best to treatment started right at the first tingle, a Care365 online pharmacist consult is well suited to getting you an antiviral cream or a fast oral antiviral option prescribed quickly, often the same day symptoms start. The assessment also checks for signs that suggest something other than a typical recurrence -- such as a first-ever outbreak, spread to the eye area, or signs of a bacterial skin infection -- since those need a different approach than routine cold sore care.

Frequently Asked Questions
This is my first-ever cold sore -- is that treated differently?
Yes. A first outbreak can be more severe and sometimes comes with fever or swollen glands, so it's usually assessed in person rather than treated the same way as a recurrence.
When is the best time to start treatment for a cold sore?
As early as possible -- ideally right when you feel that first tingling or itching sensation, before the blister even appears. Antiviral treatment is much more effective started at this prodrome stage than after the blister has fully formed.
Can a cold sore near my eye be dangerous?
Yes -- herpes affecting the eye area or causing vision changes is a different situation that needs urgent in-person assessment, since it can threaten your eyesight if not treated properly.
I get cold sores often -- is there a faster treatment option?
If you get cold sores often, a single-day oral antiviral course can be an effective option for early treatment at the first sign of a recurrence, and a pharmacist can discuss whether that approach fits your pattern.
Is it normal for a cold sore to have pus or look swollen and red?
No -- a straightforward cold sore looks like small blisters, not pus or spreading redness and swelling. Those signs suggest a secondary bacterial infection, which needs a different treatment approach.
