About Cold Sores
Cold sores (fever blisters) are small, fluid-filled blisters that typically appear on or around the lips. They're caused by the herpes simplex virus (HSV-1) and are extremely common. While there's no cure for the virus, antiviral medications can speed healing, reduce outbreak frequency, and minimize symptoms.
Common Causes
- Herpes simplex virus type 1 (HSV-1)
- Herpes simplex virus type 2 (HSV-2, less common)
- Close contact with infected person
- Sharing utensils, razors, or towels
- Triggers: stress, fatigue, illness
- Sun exposure
- Hormonal changes
- Weakened immune system

Healthcare in Lisbon: what visitors and residents should know
How local care works in Lisbon and across Lisbon Region, Portugal — and where an online doctor fits alongside it.
Lisbon is covered by several of the new Unidades Locais de Saúde, including ULS de Santa Maria in the north of the city and ULS de Lisboa Ocidental to the west, each pairing a university hospital centre with the surrounding health centres. Portugal restructured its health service on 1 January 2024: the five regional health administrations (ARS) were dissolved and replaced by 39 Unidades Locais de Saúde (ULS), each combining hospitals and health centres under one management. For non-emergency symptoms the national triage line SNS 24 (808 24 24 24) assesses you by phone and directs you to self-care, a health centre or an emergency department. EHIC and UK GHIC holders access state care on resident terms. Out of hours, pharmacies run a rota — the farmácia de serviço — posted at every closed pharmacy. Lisbon has changed faster than most European capitals in the past decade: a large influx of remote workers, digital nomads and new foreign residents has arrived alongside its established tourist flow, and many are in the country on visas that leave their health entitlement ambiguous — neither short-stay EHIC visitors nor fully registered SNS users. Registering with a health centre and being assigned a família doctor takes time these newcomers often do not yet have. The city's summers are hot and dry, and its steep cobbled hills and tram-worn pavements generate a persistent stream of falls and ankle injuries among visitors.

Cold Sores Treatment FAQs
Common questions about cold sores treatment in Lisbon
Can I get cold sore medication online in Lisbon?
Yes, our doctors can prescribe antiviral medications like valacyclovir or acyclovir. Starting treatment early (at the first tingling) can significantly reduce outbreak severity and healing time.
How effective are antivirals for cold sores?
Antiviral medications can reduce healing time by 1-2 days and decrease severity when taken at the first sign of an outbreak. For frequent outbreaks, daily suppressive therapy can reduce recurrence by up to 80%.
Can online doctors help with frequent cold sore outbreaks?
Yes, if you experience frequent outbreaks (6+ per year), our doctors can discuss suppressive antiviral therapy, which involves taking medication daily to prevent outbreaks.
Are cold sores contagious?
Yes, cold sores are highly contagious, especially when blisters are present. Our doctors will provide guidance on preventing transmission to others.
How quickly should I start cold sore treatment?
The sooner the better! Starting antiviral treatment within 24-48 hours of the first symptoms (tingling, itching) provides the best results. With UrgentDoc, you can get a prescription quickly.
