Although the cause of upper respiratory tract infection is mainly a virus, in some cases doctors still prescribe the patient to use antibiotics for upper respiratory infections. So, in what cases do you need antibiotics to treat upper respiratory infections?
1. Common cold
The common cold is an inflammatory disease of the upper respiratory tract with mild severity, a self-limited illness with symptoms of runny nose, sore throat, cough, sneezing and stuffy nose. Between 1991 and 1999, overall antibiotic use for upper respiratory tract infections (Upper respiratory tract infections and URTs for short) declined in the United States. However, the use of broad-spectrum antibiotics increased. One study reviewed randomized controlled clinical studies from 1966 to 2009 that compared antibiotic treatment with placebo in people with acute URI symptoms lasting less than seven days for a period of less than 10 days. . The authors did not find sufficient evidence to recommend antibiotics for the treatment of purulent or non-purulent rhinitis in children or adults.
2. Flu
Influenza is an acute URI caused by influenza A or B viruses, which occurs in all ages, but children have the highest incidence. Adults over 65 years of age and children under two years of age have the highest rates of death from influenza. Accordingly, the flu vaccine is the most effective way to prevent influenza. Supportive care is the cornerstone of treatment, but antiviral therapies such as the neuraminidase inhibitors oseltamivir (Tamiflu) and zanamivir (Relenza) can reduce the duration of illness if started within 48 hours of treatment. from the onset of the first symptoms. The U.S. Centers for Disease Control and Prevention (U.S. CDC) does not recommend the use of amantadine in the treatment of influenza.

For severe cases, people over 65 years of age or younger than two years, pregnant women and people with chronic illnesses should be treated with antiviral drugs. Empiric antibiotic therapy should not be continued after influenza diagnosis, unless secondary upper respiratory tract infection is present. Gram stain and culture of body fluids can be used to determine whether antibiotics should be added to the regimen along with antivirals.

3. Acute sinusitis
Acute sinusitis is a common condition and is treated as an outpatient with an annual incidence of about 13% in adults. In this pathology, inflammation takes place in the lining of the nose and sinuses with symptoms including nasal congestion, anterior or posterior rhinorrhea, facial pain, decreased sense of smell, and cough. Acute sinusitis is classified as acute when the above symptoms appear for less than 4 weeks, subacute from 4 to 12 weeks, and chronic for more than 12 weeks.
Mild cases of acute bacterial sinusitis may not require immediate medication and only observation. If symptoms worsen within seven days, the doctor will begin to prescribe antibiotics for these patients. Antibiotic therapy is acceptable in patients with severe or complicated acute bacterial sinusitis.
4. Acute otitis media
Diagnosis of acute otitis media is only diagnosed when the patient has acute symptoms and middle ear effusion. The most common causes of otitis media are H. influenzae, S. pneumoniae and M. catarrhalis. In addition, the virus has also been found in respiratory secretions of patients with acute otitis media and may be the cause of antibiotic failures. Group B Streptococcus, gram-negative enterococci, and Chlamydia trachomatis are the major causes of middle ear disease in infants younger than eight weeks of age.

Regarding the treatment regimen, antibiotics should be started immediately in children under two years of age with acute bilateral otitis media and children with acute otitis media with fluid leakage through the ear canal. Amoxicillin (80 to 90 mg per kg/day in two divided doses) is recommended as first-line treatment for acute otitis media.
If there is no response to initial antibiotic therapy within 48 to 72 hours, the patient should be reviewed to confirm the diagnosis and amoxicillin/clavulanate (Augmentin) should be started.
Children with acute otitis media should be followed up in three months for evaluation. Prolonged antibiotic therapy has been shown to reduce the number of recurrent otitis media, but is not recommended due to the risk of antibiotic resistance.
5. Pharyngitis and tonsillitis
About 90% of adults and 70% of children with sore throats have a viral infection. In people with bacterial pharyngitis, the leading cause is group A hemolytic streptococcus. Appropriate antibiotic treatment in these cases has been shown to reduce the risk of rheumatic fever. , relieves symptoms of the disease, but antibiotic treatment does not prevent nephritis.
Currently, there are many treatment methods for upper respiratory tract infections, but the disease is mainly caused by viruses, so all methods are symptomatic treatments without treating the specific cause. .
