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

Symptoms to Watch For

1
Tingling, itching, or burning around the lips (warning sign)
2
Small, painful, fluid-filled blisters
3
Blisters that merge and burst
4
Oozing and crusting
5
Swelling and redness
6
Fever and headache (first outbreak)
7
Sore throat and swollen lymph nodes
8
Painful gums

When to Seek Medical Attention

While many cases of cold sores can be treated online, you should seek immediate medical attention if you experience:

  • First cold sore outbreak
  • Cold sores near the eyes
  • Weakened immune system
  • Cold sores that don't heal within 2 weeks
  • Frequent outbreaks (more than 6 per year)
  • Severe symptoms or widespread blisters
  • Signs of bacterial infection

For emergencies, call 112 or go to the nearest hospital in Porto.

Healthcare in Porto: what visitors and residents should know

How local care works in Porto and across Norte, Portugal — and where an online doctor fits alongside it.

Porto is served by two of the new local health units — ULS de São João and ULS de Santo António — each combining a university hospital centre with health-centre groupings covering different halves of the city and its surrounding municipalities, so which unit you fall under depends on your address rather than on distance. 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. Porto's tourism has grown very rapidly around the Ribeira, the port-wine cellars of Vila Nova de Gaia and the Douro valley cruises, and much of it is short-stay city-break travel where a half-day spent in an emergency department costs a disproportionate share of the trip. The city's climate is Atlantic rather than Mediterranean — considerably wetter and cooler than the Algarve, with a long autumn and winter respiratory season — and its historic centre is steep and heavily cobbled, producing the same pattern of falls and ankle injuries as Lisbon.

  • Growing expat and remote-worker community
  • Major tourist and wine destination
  • Increasingly popular relocation city

An online consultation is not a substitute for emergency care. If you are in Porto and your symptoms are severe or life-threatening, call 112 or go to the nearest emergency department.

Cold Sores Treatment FAQs

Common questions about cold sores treatment in Porto

Can I get cold sore medication online in Porto?

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.
