About Sinus Infection
A sinus infection (sinusitis) occurs when the tissue lining the sinuses becomes inflamed and swollen, blocking the sinuses with fluid where germs can grow. Most sinus infections are caused by viruses and resolve on their own, but bacterial sinusitis may require antibiotic treatment.
Common Causes
- Viral infections (common cold)
- Bacterial infections
- Allergies
- Nasal polyps
- Deviated nasal septum
- Other medical conditions affecting mucus
- Respiratory tract infections
- Immune system disorders

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

Sinus Infection Treatment FAQs
Common questions about sinus infection treatment in Cascais
Can I get antibiotics for a sinus infection online in Cascais?
Yes, if our doctor determines you have bacterial sinusitis, they can prescribe appropriate antibiotics. Not all sinus infections need antibiotics—viral sinusitis won't respond to them—so proper diagnosis is important.
How do I know if my sinus infection is bacterial or viral?
Bacterial sinusitis often involves symptoms lasting more than 10 days, severe symptoms, or symptoms that improve then worsen. Our doctors will assess your symptoms to determine the most likely cause and appropriate treatment.
How quickly can I see a doctor for my sinus infection in Cascais?
With UrgentDoc, you can connect with an English-speaking doctor within minutes, 24/7. You don't need to wait for clinic hours or deal with language barriers.
What medications can be prescribed for sinus infections?
Our doctors can prescribe antibiotics, nasal corticosteroid sprays, decongestants, and other medications depending on your symptoms and the type of sinusitis.
How long does a sinus infection last?
Viral sinusitis typically improves within 7-10 days. With antibiotic treatment, bacterial sinusitis usually improves within a few days. Our doctors will explain what to expect with your treatment.
