Treatment is often supportive in nature, and depends on the severity and type of laryngitis (acute or chronic). General measures to relieve symptoms of laryngitis include behaviour modification, hydration and humidification.

Vocal hygiene (care of the voice) is very important to relieve symptoms of laryngitis. Vocal hygiene involves measures such as

- Resting the voice

- Drinking sufficient amounts of water

- Reducing caffeine and alcohol intake

- Stopping smoking

- Limiting throat clearing

Voice hygiene programs are given by speech-language pathologists. These programs typically include the following components:

- Addressing amount and type of voice use

- Reducing behaviours that are damaging to the vocal folds

- Increasing hydration

- Adjusting lifestyle (for example, limiting caffeine and managing medical conditions)

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

There is low or very-low quality evidence that probiotics may be better than placebo in preventing acute URTIs. Vaccination against influenza viruses, adenoviruses, measles, rubella, "Streptococcus pneumoniae", "Haemophilus influenzae", diphtheria, "Bacillus anthracis", and "Bordetella pertussis" may prevent them from infecting the URT or reduce the severity of the infection.

Most sinusitis cases are caused by viruses and resolve without antibiotics. However, if symptoms do not resolve within 10 days, amoxicillin is a reasonable antibiotic to use first for treatment with amoxicillin/clavulanate being indicated when the person's symptoms do not improve after 7 days on amoxicillin alone. A 2012 Cochrane review, however, found only a small benefit between 7 and 14 days, and could not recommend the practice when compared to potential complications and risk of developing resistance. Antibiotics are specifically not recommended in those with mild / moderate disease during the first week of infection due to risk of adverse effects, antibiotic resistance, and cost.

Fluoroquinolones, and a newer macrolide antibiotic such as clarithromycin or a tetracycline like doxycycline, are used in those who have severe allergies to penicillins. Because of increasing resistance to amoxicillin the 2012 guideline of the Infectious Diseases Society of America recommends amoxicillin-clavulanate as the initial treatment of choice for bacterial sinusitis. The guidelines also recommend against other commonly used antibiotics, including azithromycin, clarithromycin, and trimethoprim/sulfamethoxazole, because of growing antibiotic resistance. The FDA recommends against the use of fluoroquinolones when other options are available due to higher risks of serious side effects.

A short-course (3–7 days) of antibiotics seems to be just as effective as the typical longer-course (10–14 days) of antibiotics for those with clinically diagnosed acute bacterial sinusitis without any other severe disease or complicating factors. The IDSA guideline suggest five to seven days of antibiotics is long enough to treat a bacterial infection without encouraging resistance. The guidelines still recommend children receive antibiotic treatment for ten days to two weeks.

Recommended treatments for most cases of sinusitis include rest and drinking enough water to thin the mucus. Antibiotics are not recommended for most cases.

Breathing low-temperature steam such as from a hot shower or gargling can relieve symptoms. There is tentative evidence for nasal irrigation. Decongestant nasal sprays containing oxymetazoline may provide relief, but these medications should not be used for more than the recommended period. Longer use may cause rebound sinusitis. It is unclear if nasal irrigation, antihistamines, or decongestants work in children with acute sinusitis.

The Centers for Disease Control describe protocol for treating sinusitis while at the same time discouraging overuse of antibiotics:

- Target likely organisms with first-line drugs: Amoxicillin, Amoxicillin/Clavulanate

- Use shortest effective course: Should see improvement in 2–3 days. Continue treatment for 7 days after symptoms improve or resolve (usually a 10–14 day course).

- Consider imaging studies in recurrent or unclear cases: some sinus involvement is frequent early in the course of uncomplicated viral URI

Treatment comprises symptomatic support usually via analgesics for headache, sore throat and muscle aches. Moderate exercise in sedentary subjects with naturally acquired URTI probably does not alter the overall severity and duration of the illness. No randomized trials have been conducted to ascertain benefits of increasing fluid intake.

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.

This affliction is a common cause of throat irritation. Normally the stomach produces acid in the stomach which is neutralized in the small intestine. To prevent acid from flowing backwards, the lower part of the swallowing tube (esophagus) has a valve which closes after food passes through. In some individuals, this valve becomes incompetent and acid goes up into the esophagus. Reflux episodes often occur at night and one may develop a bitter taste in the mouth. The throat can be severely irritated when acid touches the vocal cords and can lead to spasms of coughing. To prevent throat irritation from reflux, one should lose weight, stop smoking, avoid coffee beverages and sleep with the head elevated.

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.

Normal surgical masks and N95 masks appear equivalent with respect to preventing respiratory infections.

In chronic recurrent sialadenitis or chronic sclerosing sialadenitis, acute attacks are managed with conservative therapies such as hydration, analgesics (mainly NSAIDs), sialogogues to stimulate salivary secretion, and regular, gentle gland massage. If infection is present, appropriate cultures should be obtained, followed by empirical antibiotic therapy initially, for example amoxicillin/clavulanate or clindamycin which cover oral flora.

If there are attacks more than approximately 3 times per year or severe attacks, surgical excision of the affected gland should be considered.

A 2014 systematic review of clinical trials does not support using routine rapid viral testing to decrease antibiotic use for children in emergency departments. It is unclear if rapid viral testing in the emergency department for children with acute febrile respiratory infections reduces the rates of antibiotic use, blood testing, or urine testing. The relative risk reduction of chest x-ray utilization in children screened with rapid viral testing is 77% compared with controls. In 2013 researchers developed a breath tester that can promptly diagnose lung infections.

The best treatment is to avoid the provoking allergen, as chronic exposure can cause permanent damage. Corticosteroids such as prednisolone may help to control symptoms but may produce side-effects.

Sialadenitis (sialoadenitis) is inflammation of a salivary gland. It may be subdivided temporally into acute, chronic and recurrent forms.

Patients with single aspergillomas generally do well with surgery to remove the aspergilloma, and are best given pre-and post-operative antifungal drugs. Often, no treatment is necessary. However, if a patient coughs up blood (haemoptysis), treatment may be required (usually angiography and embolisation, surgery or taking tranexamic acid). Angiography (injection of dye into the blood vessels) may be used to find the site of bleeding which may be stopped by shooting tiny pellets into the bleeding vessel.

For chronic cavitary pulmonary aspergillosis and chronic fibrosing pulmonary aspergillosis, lifelong use of antifungal drugs is usual. Itraconazole and voriconazole are first and second-line anti fungal agents respectively. Posaconazole can be used as third-line agent, for patients who are intolerant of or developed resistance to the first and second-line agents. Regular chest X-rays, serological and mycological parameters as well as quality of life questionnaires are used to monitor treatment progress. It is important to monitor the blood levels of antifungals to ensure optimal dosing as individuals vary in their absorption levels of these drugs.

Depending on the severity of the symptoms, FLD can last from one to to weeks, or they can last for the rest of one’s life. Acute FLD has the ability to be treated because hypersensitivity to the antigens has not yet developed. The main treatment is rest and reducing the exposure to the antigens through masks and increased airflow in confined spaces where the antigens are present. Another treatment for acute FLD is pure oxygen therapy. For chronic FLD, there is no true treatment because the patient has developed hypersensitivity meaning their FLD could last the rest of their life. Any exposure to the antigens once hypersensitivity can set off another chronic reaction.

Antibiotic therapy has to overcome the blood/prostate barrier that prevents many antibiotics from reaching levels that are higher than minimum inhibitory concentration. A blood-prostate barrier restricts cell and molecular movement across the rat ventral prostate epithelium. Treatment requires prolonged courses (4–8 weeks) of antibiotics that penetrate the prostate well. The fluoroquinolones, tetracyclines and macrolides have the best penetration. There have been contradictory findings regarding the penetrability of nitrofurantoin , quinolones (ciprofloxacin, levofloxacin), sulfas (Bactrim, Septra), doxycycline and macrolides (erythromycin, clarithromycin). This is particularly true for gram-positive infections.

In a review of multiple studies, Levofloxacin (Levaquin) was found to reach prostatic fluid concentrations 5.5 times higher than Ciprofloxacin, indicating a greater ability to penetrate the prostate.

Persistent infections may be helped in 80% of patients by the use of alpha blockers (tamsulosin (Flomax), alfuzosin), or long term low dose antibiotic therapy. Recurrent infections may be caused by inefficient urination (benign prostatic hypertrophy, neurogenic bladder), prostatic stones or a structural abnormality that acts as a reservoir for infection.

In theory, the ability of some strains of bacteria to form biofilms might be one factor amongst others to facilitate development of chronic bacterial prostatitis.

Escherichia coli extract and cranberry have a potentially preventive effect on the development of chronic bacterial prostatitis, while combining antibiotics with saw palmetto, lactobacillus sporogens and arbutin may lead to better treatment outcomes.

Bacteriophages hold promise as another potential treatment for chronic bacterial prostatatis.

The addition of prostate massage to courses of antibiotics was previously proposed as being beneficial and prostate massage may mechanically break up the biofilm and enhance the drainage of the prostate gland. However, in more recent trials, this was not shown to improve outcome compared to antibiotics alone.

Nasal vestibulitis is the diffuse dermatitis of nasal vestibule. It is often caused by "Staphylococcus aureus." It may be secondary to chronic rhinorrhea, nose picking or viral infections. In acute vestibulitis, the skin is red, swollen and tender. In chronic vestibulitis, induration of vestibular skin and crusting is seen. It is treated by cleaning the nasal vestibule of all crusts with a cotton applicator soaked in hydrogen peroxide. Antibiotic steroid ointment is sometimes helpful. Chronic fissures are treated by cautery.

The only prevention for FLD is ventilating the work areas putting workers at risk and using face masks to filter out the antigens attempting to enter the lungs through the air.

A number of endoscopic devices have been tested to treat chronic heartburn.

- Endocinch, puts stitches in the lower esophogeal sphincter (LES) to create small pleats to help strengthen the muscle. However, long-term results were disappointing, and the device is no longer sold by Bard.

- Stretta procedure, uses electrodes to apply radio-frequency energy to the LES. A 2015 systematic review and meta-analysis in response to the systematic review (no meta-analysis) conducted by SAGES did not support the claims that Stretta was an effective treatment for GERD. A 2012 systematic review found that it improves GERD symptoms.

- NDO Surgical Plicator creates a plication, or fold, of tissue near the gastroesophageal junction, and fixates the plication with a suture-based implant. The company ceased operations in mid-2008, and the device is no longer on the market.

- Transoral incisionless fundoplication, which uses a device called Esophyx, may be effective.

Hypersensitivity pneumonitis may also be called many different names, based on the provoking antigen. These include:

Of these types, Farmer's Lung and Bird-Breeder's Lung are the most common. "Studies document 8-540 cases per 100,000 persons per year for farmers and 6000-21,000 cases per 100,000 persons per year for pigeon breeders. High attack rates are documented in sporadic outbreaks. Prevalence varies by region, climate, and farming practices. HP affects 0.4–7% of the farming population. Reported prevalence among bird fanciers is estimated to be 20-20,000 cases per 100,000 persons at risk."

Certain foods and lifestyle are considered to promote gastroesophageal reflux, but most dietary interventions have little supporting evidence. Avoidance of specific foods and of eating before lying down should be recommended only to those in which they are associated with the symptoms. Foods that have been implicated include coffee, alcohol, chocolate, fatty foods, acidic foods, and spicy foods. Weight loss and elevating the head of the bed are generally useful. A wedge pillow that elevates the head may inhibit gastroesophageal reflux during sleep. Stopping smoking and not drinking alcohol do not appear to result in significant improvement in symptoms. Although moderate exercise may improve symptoms in people with GERD, vigorous exercise may worsen them.

Medical and surgical treatments have been recommended to treat organic dysphonias. An effective treatment for spasmodic dysphonia (hoarseness resulting from periodic breaks in phonation due to hyperadduction of the vocal folds) is botulinum toxin injection. The toxin acts by blocking acetylcholine release at the thyro-arytenoid muscle. Although the use of botlinum toxin injections is considered relatively safe, patients' responses to treatment differ in the initial stages; some have reported experiencing swallowing problems and breathy voice quality as a side-effect to the injections. Breathiness may last for a longer period of time for males than females.

Surgeries involve myoectomies of the laryngeal muscles to reduce voice breaks, and laryngoplasties, in which laryngeal cartilage is altered to reduce tension.

Over time, the relapse rate is high, exceeding 50%. However, recent research indicates that combination therapies offer a better prognosis than antibiotics alone.

A 2007 study showed that repeated combination pharmacological therapy with antibacterial agents (ciprofloxacin/azithromycin), alpha-blockers (alfuzosin) and Serenoa repens extracts may eradicate infection in 83.9% of patients with clinical remission extending throughout a follow-up period of 30 months for 94% of these patients.

A 2014 study of 210 patients randomized into two treatment groups found that recurrence occurred within 2 months in 27.6% of the group using antibiotics alone (prulifloxacin 600 mg), but in only 7.8% of the group taking prulifloxacin in combination with Serenoa repens extract, Lactobacillus Sporogens and Arbutin.
