In addition, people should be given antibiotics, such as second- or third-generation cephalosporins, either alone or in combination with penicillin or ampicillin for streptococcal coverage. If allergy to penicillins is present, Co-trimoxazole or clindamycin is an alternative.

Epiglottitis may require urgent tracheal intubation to protect the airway, though this is not always the case. A surgical airway opening (cricothyrotomy) may be required if intubation is not possible.

Corticosteroids, such as dexamethasone and budesonide, have been shown to improve outcomes in children with all severities of croup. Significant relief is obtained as early as six hours after administration. While effective when given by injection, or by inhalation, giving the medication by mouth is preferred. A single dose is usually all that is required, and is generally considered to be quite safe. Dexamethasone at doses of 0.15, 0.3 and 0.6 mg/kg appear to be all equally effective.

Moderate to severe croup may be improved temporarily with nebulized epinephrine. While epinephrine typically produces a reduction in croup severity within 10–30 minutes, the benefits last for only about 2 hours. If the condition remains improved for 2–4 hours after treatment and no other complications arise, the child is typically discharged from the hospital.

Prescribing antibiotics for laryngitis is not suggested practice. The antibiotics penicillin V and erythromycin are not effective for treating acute laryngitis. Erythromycin may improve voice disturbances after one week and cough after two weeks, however any modest subjective benefit is not greater than the adverse effects, cost, and the risk of bacteria developing resistance to the antibiotics. Health authorities have been strongly encouraging physicians to decrease the prescribing of antibiotics to treat common upper respiratory tract infections because antibiotic usage does not significantly reduce recovery time for these viral illnesses. Decreased antibiotic usage could also have prevented drug resistant bacteria. Some have advocated a delayed antibiotic approach to treating URIs which seeks to reduce the consumption of antibiotics while attempting to maintain patient satisfaction. Most studies show no difference in improvement of symptoms between those treated with antibiotics right away and those with delayed prescriptions. Most studies also show no difference in patient satisfaction, patient complications, symptoms between delayed and no antibiotics. A strategy of "no antibiotics" results in even less antibiotic use than a strategy of "delayed antibiotics".

Evidence does not support the general use of antibiotics in acute bronchitis. While some evidence suggests antibiotics speed up resolution of the cough by about 12 hours there is a greater risk of gastrointestinal problems and no change in longer term outcomes. Antibiotics use also leads to the promotion of antibiotic-resistant bacteria, which increase morbidity and mortality.

Most cases are self-limited and resolve themselves in a few weeks.

There is no good evidence supporting the effectiveness of over-the-counter cough medications for reducing coughing in adults or children. Children under 2 years old should not be given any type of cough or cold medicine due to the potential for life-threatening side effects. In addition, according to the American Academy of Pediatrics, the use of cough medicine to relieve cough symptoms should be avoided in children under 4 years old, and the safety is questioned for children under 6 years old.

In general, acute laryngitis treatment involves vocal hygiene, painkillers (analgesics), humidification, and antibiotics.

The suggested treatment for viral laryngitis involves vocal rest, pain medication, and mucolytics for frequent coughing. Home remedies such as tea and honey may also be helpful. Antibiotics are not used for treatment of viral laryngitis.

Gargling salt water is often suggested but evidence looking at its usefulness is lacking. Alternative medicines are promoted and used for the treatment of sore throats. However, they are poorly supported by evidence.

The majority of time treatment is symptomatic. Specific treatments are effective for bacterial, fungal, and herpes simplex infections.

There should also be a "care plan" in case of future exacerbations. Patients may watch for symptoms, such as shortness of breath, change in character or amount of mucus, and start self-treatment as discussed with a health care provider. This allows for treatment right away until a doctor can be seen.

The symptoms of acute exacerbations are treated using short-acting bronchodilators. A course of corticosteroids, usually in tablet or intravenous rather than inhaled form, can speed up recovery. The IV and oral forms of steroids have been found to be equivalent. Antibiotics are often used but will only help if the exacerbation is due to an infection. Antibiotics are indicated when a patient notes increased sputum production, purulent sputum, increased dyspnea, has an elevated white count, or is febrile. Examples of first-line antibiotics are amoxicillin, doxycycline and co-trimoxazole.

The majority of cases of throat irritation usually go away without any treatment. There is no real treatment for throat irritation from a virus. If you have difficulty swallowing then one should drink liquids, suck on lozenges, ice chips or mix salt with warm water to gargle. Bacterial infections generally require antibiotics.

Home remedies for throat irritation include gargling with warm water twice a day, sipping honey and lemon mixture or sucking on medicated lozenges. If the cause is dry air, then one should humidify the home. Since smoke irritates the throat, stop smoking and avoid all fumes from chemicals, paints and volatile liquids.

Rest your voice if you have been screaming or singing. If you have pharyngitis, avoid infecting others by covering your mouth when coughing and wear a mask.

Prevention is by not smoking and avoiding other lung irritants. Frequent hand washing may also be protective. Treatment of acute bronchitis typically involves rest, paracetamol (acetaminophen), and NSAIDs to help with the fever. Cough medicine has little support for its use and is not recommended in children less than six years of age. There is tentative evidence that salbutamol may be useful in those with wheezing; however, it may result in nervousness and tremors. Antibiotics should generally not be used. An exception is when acute bronchitis is due to pertussis. Tentative evidence supports honey and pelargonium to help with symptoms. Getting plenty of rest and fluids is also often recommended.

Oxygen therapy should be initiated if there is significantly low blood oxygen. High flow oxygen may be harmful in those with an acute exacerbation of COPD. In the prehospital environment those given high flow O rather than titrating their O saturations to 88% to 92% had worse outcomes.

Oral and topical pain killers are effective to treat the pain caused by otitis media. Oral agents include ibuprofen, paracetamol (acetaminophen), and opiates. Topical agents shown to be effective include antipyrine and benzocaine ear drops. Decongestants and antihistamines, either nasal or oral, are not recommended due to the lack of benefit and concerns regarding side effects. Half of cases of ear pain in children resolve without treatment in three days and 90% resolve in seven or eight days. The use of steroids is not supported by the evidence for acute otitis media.

It is important to weigh the benefits and harms before using antibiotics for acute otitis media. As over 82% of acute episodes settle without treatment, about 20 children must be treated to prevent one case of ear pain, 33 children to prevent one perforation, and 11 children to prevent one opposite-side ear infection. For every 14 children treated with antibiotics, one child has an episode of either vomiting, diarrhea or a rash. If pain is present, treatment to reduce it should be initiated.

- Antibiotics should be prescribed for severe bilateral or unilateral disease in all infants and children with severe signs and symptoms, such as moderate to severe ear pain and high fever.

- For bilateral acute otitis media in infants younger than 24 months of age, without severe signs and symptoms, antibiotics should be prescribed.

- When non-severe unilateral acute otitis media is diagnosed in young children either antibiotic therapy is given or observation with close follow-up based on joint decision making between parent(s)/caregiver in infants 6 to 23 months of age. If the child worsens or fails to improve in 2 to 3 days antibiotics should be administered.

- Children 24 months or older with non-severe disease can have either antibiotics or observation.

The first line antibiotic treatment, if warranted, is amoxicillin. If there is resistance or use of amoxicillin in the last 30 days then amoxicillin-clavulanate or another penicillin derivative plus beta lactamase inhibitor is recommended. Taking amoxicillin once a day may be as effective as twice or three times a day. While less than 7 days of antibiotics have less side effects, more than seven days appear to be more effective. If there is no improvement after 2–3 days of treatment a change in therapy may be considered.

A treatment option for chronic suppurative otitis media with discharge is topical antibiotics. A Cochrane review found that topical quinolone antibiotics can improve discharge better than oral antibiotics. Safety is not really clear.

"Haemophilus influenzae" produces beta-lactamases, and it is also able to modify its penicillin-binding proteins, so it has gained resistance to the penicillin family of antibiotics.

In severe cases, cefotaxime and ceftriaxone delivered directly into the bloodstream are the elected antibiotics, and, for the less severe cases, an association of ampicillin and sulbactam, cephalosporins of the second and third generation, or fluoroquinolones are preferred. (Fluoroquinolone-resistant "Haemophilus influenzae" have been observed.)

Macrolide antibiotics (e.g., clarithromycin) may be used in patients with a history of allergy to beta-lactam antibiotics. Macrolide resistance has also been observed.

Evidence suggests that the decline in lung function observed in chronic bronchitis may be slowed with smoking cessation. Chronic bronchitis is treated symptomatically and may be treated in a nonpharmacologic manner or with pharmacologic therapeutic agents. Typical nonpharmacologic approaches to the management of COPD including bronchitis may include: pulmonary rehabilitation, lung volume reduction surgery, and lung transplantation. Inflammation and edema of the respiratory epithelium may be reduced with inhaled corticosteroids. Wheezing and shortness of breath can be treated by reducing bronchospasm (reversible narrowing of smaller bronchi due to constriction of the smooth muscle) with bronchodilators such as inhaled long acting β-adrenergic receptor agonists (e.g., salmeterol) and inhaled anticholinergics such as ipratropium bromide or tiotropium bromide. Mucolytics may have a small therapeutic effect on acute exacerbations of chronic bronchitis. Supplemental oxygen is used to treat hypoxemia (too little oxygen in the blood) and has been shown to reduce mortality in chronic bronchitis patients. Oxygen supplementation can result in decreased respiratory drive, leading to increased blood levels of carbon dioxide (hypercapnia) and subsequent respiratory acidosis.

Antibiotics do not help the many lower respiratory infections which are caused by parasites or viruses. While acute bronchitis often does not require antibiotic therapy, antibiotics can be given to patients with acute exacerbations of chronic bronchitis. The indications for treatment are increased dyspnoea, and an increase in the volume or purulence of the sputum. The treatment of bacterial pneumonia is selected by considering the age of the patient, the severity of the illness and the presence of underlying disease. Amoxicillin and doxycycline are suitable for many of the lower respiratory tract infections seen in general practice.

The serious complications of HiB are brain damage, hearing loss, and even death.

Vaccination helps prevent bronchopneumonia, mostly against influenza viruses, adenoviruses, measles, rubella, streptococcus pneumoniae, haemophilus influenzae, diphtheria, bacillus anthracis, chickenpox, and bordetella pertussis.

Treatment is primarily supportive. Management in an intensive care unit is required and the need for mechanical ventilation is common. Therapy with corticosteroids is generally attempted, though their usefulness has not been established. The only treatment that has met with success to date is a lung transplant.

Before the development of modern cardiovascular surgery, cases of acute mediastinitis usually arose from either perforation of the esophagus or from contiguous spread of odontogenic or retropharyngeal infections. However, in modern practice, most cases of acute mediastinitis result from complications of cardiovascular or endoscopic surgical procedures.

Treatment usually involves aggressive intravenous antibiotic therapy and hydration. If discrete fluid collections or grossly infected tissue have formed (such as abscesses), they may have to be surgically drained or debrided.
