Flu treatment

Symptoms

• Fever or chills: A sudden temperature over 100.4°F, though not everyone with the flu runs a fever.
• Cough: Usually dry and persistent, sometimes lingering for a week or more.
• Sore throat: Scratchy or painful throat, often alongside cough and congestion.
• Runny or stuffy nose: Nasal congestion or drainage, more prominent early on.
• Muscle or body aches: Widespread soreness and aching, often severe with influenza.
• Headache: Common and sometimes intense during the first days of illness.
• Fatigue: Marked tiredness and weakness that can last one to two weeks.
• Vomiting or diarrhea: More common in children than adults with the flu.
• Shortness of breath: Difficulty breathing is a warning sign that needs urgent evaluation.
• Chest discomfort: Chest pain or pressure should be evaluated in an ER right away.

When It's an Emergency

Call 911 or come to Bellaire ER right away if the flu causes trouble breathing, shortness of breath, or chest pain or pressure that does not go away. In children, watch for fast or labored breathing, bluish lips or face, ribs pulling in with each breath, or a child who is too sleepy to interact or will not drink fluids.

Signs of dehydration are a common reason the flu becomes an emergency: little or no urine, dizziness when standing, a very dry mouth, or in infants no wet diaper for many hours and no tears when crying. Persistent vomiting that prevents keeping fluids down also needs prompt care.

Seek emergency care for a high fever that will not come down with medication, confusion or difficulty waking, seizures, or severe weakness. A warning pattern is flu symptoms that improve and then return with a worse fever and cough, which can signal a secondary infection such as pneumonia.

People at higher risk of complications should have a lower threshold for the ER: adults 65 and older, young children, pregnant patients, and anyone with asthma, COPD, heart disease, diabetes, or a weakened immune system.

When It's Not an Emergency

Most healthy adults and older children with the flu can recover safely at home with rest, fluids, and over-the-counter fever and pain relievers. Telemedicine or an online urgent care visit is a reasonable first step when your symptoms are typical and you are breathing normally, staying hydrated, and generally stable.

A telemedicine or urgent care clinician can confirm the flu is the likely cause, and if you are within about 48 hours of your first symptoms they can prescribe an antiviral such as oseltamivir (Tamiflu) that may shorten the illness. This is especially worth doing early if you are in a higher-risk group.

Choose home care or a virtual visit for a manageable fever, body aches, cough, sore throat, and congestion without red-flag symptoms. If you are unsure, or if symptoms worsen rather than steadily improve after a few days, escalate to in-person care.

What Happens at Bellaire ER

At Bellaire ER you are seen quickly by a board-certified emergency physician who reviews your symptoms and examines you. When it helps confirm the diagnosis or rule out complications, we can run a rapid flu swab and other lab tests on-site, check your oxygen level, and take a chest X-ray to look for pneumonia.

Treatment is tailored to how sick you are. That may include IV fluids for dehydration, medication to control fever and nausea, an antiviral such as oseltamivir when appropriate, and oxygen or breathing treatments if needed. Because our on-site CT, X-ray, ultrasound, and full lab are in the building, we diagnose and treat in a single visit.

Most patients are treated and released the same visit without needing a hospital transfer. Before you leave, your physician explains your results, any prescriptions, and a clear plan for follow-up and warning signs to watch for.

Prevention

The best protection against the flu is the annual flu vaccine, recommended by the CDC for almost everyone age 6 months and older, ideally before flu season begins. Vaccination lowers your chance of getting the flu and reduces the severity of illness if you do get sick.

Everyday habits also help: wash your hands often, avoid touching your eyes, nose, and mouth, cover coughs and sneezes, and stay away from people who are sick. If you do come down with the flu, stay home until you have been fever-free for at least 24 hours without fever-reducing medication to avoid spreading it to others.
