A blocked nose and sinus pressure usually follow a cold or allergy and settle within a couple of weeks. Most sinus infections are viral, so antibiotics are rarely needed — steam, saline and decongestion help.
Short-term decongestant sprays (no more than 5–7 days)
Antihistamines/steroid nasal spray if allergy is the cause
Pain relief for sinus pain; stay hydrated
Most sinusitis is viral and does NOT need antibiotics
When to see a doctor urgently
Severe headache, swelling around the eye, or vision changes (urgent)
High fever, or symptoms worsening after initially improving (possible bacterial sinusitis)
Symptoms lasting more than 10–14 days
Do not overuse decongestant sprays (rebound blockage)
Most sinusitis is viral. Antibiotics rarely help sinusitis, which is usually viral — steam, saline and time work. Swelling around the eye or vision changes are red flags needing urgent care. MedDroid gives general information, not a diagnosis.
Frequently asked questions
How do I unblock my nose?
Steam inhalation, saline rinses/sprays, and short-term decongestant sprays (max ~5–7 days) help. Treat allergy with antihistamines or a steroid nasal spray.
Do I need antibiotics for sinusitis?
Usually not — most sinusitis is viral and settles on its own. Antibiotics are only for suspected bacterial sinusitis (severe, prolonged or worsening after improvement).
Why does my nose get more blocked after using a spray?
Overusing decongestant sprays beyond about a week causes rebound congestion. Use them only short-term.
