Respiratory tract infections are very common illnesses caused by viruses or bacteria that infect the airways and lungs. From the common cold to pneumonia, respiratory infections can affect people of all ages. While most respiratory infections get better on their own, there are treatments available to help relieve symptoms and speed up recovery. This article provides an overview of various respiratory tract infections and their treatment options.

Types of Respiratory Tract Infections

There are several types of Respiratory Tract Infection Treatment  based on which part of the respiratory system is affected:

Upper Respiratory Infections
- Common Cold: A viral infection of the nose and throat, colds are the most common respiratory illness. Symptoms include runny nose, sore throat, coughing and sneezing.
- Sinusitis: Infection and inflammation of the sinuses caused by viruses or bacteria. Symptoms include nasal congestion, facial pain, headache and fever.

Lower Respiratory Infections
- Bronchitis: Inflammation of the main airways (bronchi) leading to coughing, wheezing and difficulty breathing. Acute bronchitis lasts less than 3 weeks while chronic bronchitis persists for longer.
- Pneumonia: Infection and swelling of the lungs which can be bacterial, viral or fungal in origin. Symptoms include cough, fever, chest pain and difficulty breathing.

Treatment Options for Respiratory Infections

As respiratory infections are usually caused by viruses, antibiotics do not help cure most upper respiratory infections like the common cold and sinusitis. However, medications are available to relieve symptoms and speed up recovery:

- Over-the-counter pain relievers and fever reducers like acetaminophen (Tylenol), ibuprofen (Advil) to treat headaches, body aches and fever.
- Decongestants like pseudoephedrine (Sudafed) to relieve nasal congestion.
- Antihistamines like loratadine (Claritin) to reduce sneezing, runny nose and itching.
- Nasal saline sprays and washes help thin and clear mucus.
- Cough suppressants to treat cough symptoms.
- Antibiotics are prescribed only for bacterial infections like sinusitis and pneumonia to fight the infection.

Additional Treatments and Home Remedies

Along with medications, certain lifestyle changes and home remedies help manage respiratory infection symptoms:

- Getting plenty of rest allows the body's natural defenses to fight infection.
- Drinking adequate fluids keeps nasal and chest secretions thin. Warm liquids like chicken broth are especially soothing.
- Using a humidifier adds moisture to dry air and soothes irritated airways.
- Applying a warm compress over the sinus area or chest promotes drainage and relieves congestion.
- Gargling salt water soothes sore throats and reduces inflammation.
- Inhaling steam from a pot of boiling water or taking a hot shower helps loosen secretions.
- Menthol rubs provide cooling relief when applied to the chest, nose or throat areas.
- Honey has antiviral and antibacterial properties and coats the throat for a soothing effect.

Treating Lower Respiratory Infections

Bronchitis and pneumonia require additional treatment as they affect the lower respiratory tract:

- Antibiotics fight the underlying bacterial infection in cases of acute bronchitis (lasting 5–10 days) and pneumonia. Common antibiotics include amoxicillin, azithromycin and doxycycline.
- Cough suppressants may be prescribed around-the-clock to prevent coughing fits.
- Expectorants thin secretions and make coughs more productive to bring up mucus.
- Inhaled bronchodilators like albuterol open swollen airways for those with wheezing.
- Severe pneumonia may require hospitalization, intravenous (IV) antibiotics and oxygen therapy.
- Pneumonia vaccines like pneumococcal (PCV13) and annual flu vaccines prevent future infections.

When to See a Doctor

See a doctor promptly for any respiratory infection that does not improve after a week, or if symptoms worsen with fever, difficulty breathing or a severe cough that interrupts sleep. Red flags that require urgent medical attention include:

- Fever over 102°F
- Coughing up bloody or rust-colored phlegm
- Wheezing or shortness of breath even when at rest
- Pains in the chest when breathing or coughing
- Feeling faint, dizzy or confused
- Being older than 65 or having a chronic medical condition

With prompt treatment, most respiratory infections can clear up within a week or two. Seeing a doctor ensures the correct diagnosis and appropriate treatment for proper recovery and prevention of complications. Following treatment advice and allowing time for the immune system to kick in is key to overcoming respiratory infections.
