What is sinusitis?

Sinusitis is swelling of the sinuses, usually after a cold. It causes facial pain or pressure, a blocked or runny nose, reduced sense of smell, and sometimes fever. Most cases are viral and clear within 2 to 3 weeks without antibiotics. Chronic sinusitis lasting more than 12 weeks may need specialist treatment.

When NHS resources suggest seeing a GP

  • You think you have sinusitis.
  • Your child is aged 12 years or older and you think they have sinusitis.
  • A pharmacist can give the same treatments as a GP for sinusitis. They can also give advice or direct you to other medical help if needed.
  • You, or a child, have sinusitis symptoms and:
  • You do not get better after 7 days of treatment from a pharmacy or GP.
  • You do not get better after 3 weeks of treating symptoms yourself.
  • You keep getting sinusitis.
  • Your child is aged 11 years or younger.
  • You, or a child, has sinusitis symptoms and:
  • You are very unwell.
  • Painkillers do not help or symptoms get worse.
  • You have a weakened immune system – for example, because you're having chemotherapy.
  • You can call 111 or get help from 111 online. Call 111 if you need advice for a child under 5 years old.

Common questions

Do sinus infections need antibiotics?

Most sinusitis is viral and clears on its own. Antibiotics are only considered if symptoms are severe, last more than 10 days without improvement, or suggest bacterial infection. A pharmacist can recommend decongestants and pain relief.

How can I relieve sinus pressure at home?

Try steam inhalation, saline nasal rinses or sprays, decongestant sprays for up to 7 days, and paracetamol or ibuprofen. Sleeping propped up and warm compresses over the face can help too.

When should I see a GP for sinusitis?

See a GP if symptoms last more than 10 days without improvement, get worse after initially improving, include high fever or severe facial swelling, or affect your vision. Chronic sinusitis lasting over 12 weeks also needs review.
