Flu (Influenza) Treatment

What is the Flu?
Influenza, commonly called “the flu,” is a contagious respiratory illness caused by influenza viruses. Unlike the common cold, flu symptoms come on suddenly and are typically more severe. The flu can lead to serious complications, especially in young children, older adults, pregnant women, and people with chronic health conditions.
At Urgent Care USA, we see hundreds of flu cases each season. Early treatment with antiviral medications can shorten the duration of illness and prevent complications. Don’t wait – if you suspect the flu, visit us within 48 hours of symptom onset for maximum treatment effectiveness.

FAQ’s
Frequently Asked Questions
How long is the flu contagious?
You’re most contagious in the first 3-4 days of illness but can spread flu from 1 day before symptoms start to 5-7 days after becoming sick.
Can I get the flu from the flu shot?
No. The flu vaccine contains inactivated virus that cannot cause flu. You may have mild side effects like soreness at the injection site.
Why do I need a flu shot every year?
Flu viruses change constantly, and each year’s vaccine is formulated to protect against the strains most likely to circulate that season.
Is it too late to treat the flu after 48 hours?
While antivirals work best within 48 hours, they may still provide benefit if started later, especially for high-risk patients.
Can I get the flu twice in one season?
Yes, because different flu strains circulate. Having flu from one strain doesn’t protect you from others.
