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

Healthcare in Cascais: what visitors and residents should know
How local care works in Cascais and across Lisbon Region, Portugal — and where an online doctor fits alongside it.
Cascais sits within ULS de Lisboa Ocidental — the local health unit that took over the Cascais health-centre grouping in the 2024 reorganisation, alongside those of western Lisbon and Oeiras. 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. Cascais has one of the highest concentrations of foreign residents in Portugal: the coastal strip out through Estoril and Quinta da Marinha has long attracted expatriate families, international-school communities and, more recently, remote workers relocating from Northern Europe and North America. That population is permanent rather than seasonal, so the dominant need is continuity of care — repeat prescriptions, ongoing-condition management, paediatric care for school-age children — rather than holiday medicine. The town is on the exposed Atlantic coast west of Lisbon, with strong surf at Guincho and consistent wind, giving it a year-round pattern of water-sport injuries, and a cooler, breezier climate than the city half an hour inland.
- Affluent international expat community
- Popular with families and relocating professionals
- High-end healthcare expectations

Cold Sores Treatment FAQs
Common questions about cold sores treatment in Cascais
Can I get cold sore medication online in Cascais?
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?
