Wondering if a sinus infection requires antibiotics? Many sinus infections are caused by a virus, which means antibiotics may not help.
Guidelines suggest checking your symptom pattern. If you’ve been sick fewer than 10 days and symptoms aren’t getting worse, it’s likely viral. If symptoms worsen over 10 days or improve and then go downhill, it’s more likely bacterial and may need antibiotics.
If you’re not sure where you fall, an ENT visit can help you get the right treatment.
