A number of medications have been used to treat vulvodynia. Evidence to support their use, however, is often poor. These include creams and ointments containing lidocaine, estrogen or tricyclic antidepressants. Antidepressants and anticonvulsants in pill form are sometimes tried but have been poorly studied. Injectable medications included steroids and botulinum toxin have been tried with limited success.

A number of lifestyle changes are often recommended such as using cotton underwear, not using substances that may irritate the area, and using lubricant during sex. The use of alternative medicine has not been sufficiently studied to make recommendations.

In cases of viral adenoiditis, treatment with analgesics or antipyretics is often sufficient. Bacterial adenoiditis may be treated with antibiotics, such as amoxicillin - clavulanic acid or a cephalosporin. In case of adenoid hypertrophy, adenoidectomy may be performed to remove the adenoid.

For unconfirmed acute sinusitis, intranasal corticosteroids have not been found to be better than a placebo either alone or in combination with antibiotics. For cases confirmed by radiology or nasal endoscopy, treatment with corticosteroids alone or in combination with antibiotics is supported. The benefit, however, is small.

There is only limited evidence to support short treatment with oral corticosteroids for chronic rhinosinusitis with nasal polyps.

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.

Antibiotics are commonly used to prevent secondary bacterial infection. There are no specific antiviral drugs in common use at this time for FVR, although one study has shown that ganciclovir, PMEDAP, and cidofovir hold promise for treatment. More recent research has indicated that systemic famciclovir is effective at treating this infection in cats without the side effects reported with other anti-viral agents. More severe cases may require supportive care such as intravenous fluid therapy, oxygen therapy, or even a feeding tube. Conjunctivitis and corneal ulcers are treated with topical antibiotics for secondary bacterial infection.

Lysine is commonly used as a treatment, however in a 2015 systematic review, where the authors investigated all clinical trials with cats as well as "in vitro" studies, concluded that lysine supplementation is not effective for the treatment or prevention of feline herpesvirus 1 infection.

In most cases treatment for rhinorrhea is not necessary since it will clear up on its own—especially if it is the symptom of an infection. For general cases blowing your nose can get rid of the mucus buildup. Though blowing may be a quick-fix solution, it would likely proliferate mucosal production in the sinuses, leading to frequent and higher mucus buildups in the nose. Alternatively, saline nasal sprays and vasoconstrictor nasal sprays may also be used, but may become counterproductive after several days of use, causing rhinitis medicamentosa.

In recurring cases, such as those due to allergies, there are medicinal treatments available. For cases caused by histamine buildup, several types of antihistamines can be obtained relatively cheaply from drugstores.

People who prefer to keep clear nasal passages, such as singers, who need a clear nasal passage to perform, may use a technique called "nasal irrigation" to prevent rhinorrhea. Nasal irrigation involves rinsing the nasal cavity regularly with salty water or store bought saline solutions.

Treatment of atrophic rhinitis can be either medical or surgical.

Medical measures include:

- Nasal irrigation using normal saline

- Nasal irrigation and removal of crusts using alkaline nasal solutions prepared by dissolving a spoonful of powder containing one part sodium bicarbonate, one part sodium biborate and two part sodium chloride.

- 25% glucose in glycerine can be applied to the nasal mucosa to inhibit the growth of proteolytic organisms which produce foul smell.

- Local antibiotics, such as chloromycetine.

- Vitamin D (Kemicetine).

- Estradiol spray for regeneration of seromucinous glands and vascularization of mucosa.

- Systemic streptomycin (1g/day) against Klebsiella organisms.

- Oral potassium iodide for liquefaction of secretion.

- Placental extract injected in the submucosa.

Surgical interventions include:

- Young's operation.

- Modified Young's operation.

- Narrowing of nasal cavities, submucosal injection of Teflon paste, section and medial displacement of the lateral wall of the nose.

- Transposition of parotid duct to maxillary sinus or nasal mucosa.

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.

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".

The treatment of RM involves withdrawal of the offending nasal spray or oral medication. Both a "cold turkey" and a "weaning" approach can be used. Cold turkey is the most effective treatment method, as it directly removes the cause of the condition, yet the time period between the discontinuation of the drug and the relief of symptoms may be too long and uncomfortable for some individuals (particularly when trying to go to sleep when they are unable to breathe through their nose).

A benefit of the gradual “weaning” approach is that it helps preserve normal nasal airflow during the withdrawal process. United States Patent Number 5,988,870 was issued for a method and apparatus used to facilitate the precise titration and gradual withdrawal of decongestant nasal sprays containing addictive compounds. The system is sold under the brand name Rhinostat.

The use of over-the-counter (OTC) saline nasal sprays may help open the nose without causing RM if the spray does not contain a decongestant. Symptoms of congestion and runny nose can often be treated with corticosteroid nasal sprays under the supervision of a physician. For very severe cases, oral steroids or nasal surgery may be necessary.

For RM caused by topical decongestants, there are anecdotal reports of persons having success by withdrawing treatment from one nostril at a time.

A study has shown that the anti-infective agent benzalkonium chloride, which is frequently added to topical nasal sprays as a preservative, aggravates the condition by further increasing the rebound swelling.

The treatment of nasal congestion frequently depends on the underlying cause.

Alpha-adrenergic agonists are the first treatment of choice. They relieve congestion by constricting the blood vessels in the nasal cavity, thus resulting in relieved symptoms. Examples include oxymetazoline and phenylephrine.

Both influenza and the common cold are self-limiting conditions that improve with time; however, drugs such as acetaminophen (paracetamol), aspirin, and ibuprofen may help with the discomfort.

A cause of nasal congestion may also be due to an allergic reaction caused by hay fever, so avoiding allergens is a common remedy if this becomes a confirmed diagnosis. Antihistamines and decongestants can provide significant symptom relief although they do not cure hay fever. Antihistamines may be given continuously during pollen season for optimum control of symptoms. Topical decongestants should only be used by patients for a maximum of 3 days in a row, because rebound congestion may occur in the form of rhinitis medicamentosa.

Nasal decongestants target discomfort directly. These come as nasal sprays like naphazoline (Privine), oxymetazoline (Afrin, Dristan, Duramist), as inhalers, or phenylephrine (Neo-Synephrine, Sinex, Rhinall) or as oral pills (Bronkaid, Sudafed, Neo-Synephrine, Sinex, Rhinall). Oral decongestants may be used for up to a week without consulting a doctor, with the exception of Bronkaid and Sudafed, which can be taken as long as needed, but nasal sprays can also cause "rebound" (Rhinitis medicamentosa) and worsen the congestion if taken for more than a few days. Therefore, you should only take nasal sprays when discomfort cannot be remedied by other methods, and never for more than three days.

If an infant is unable to breathe because of a plugged nose, a nasal aspirator may be useful to remove the mucus. The mucus might be thick and sticky, making it difficult to expel from the nostril.

According to a Cochrane review, single oral dose of nasal decongestant in the common cold is modestly effective for the short term relief of congestion in adults; however, "there is insufficient data on the use of decongestants in children." Therefore, decongestants are not recommended for use in children under 12 years of age with the common cold. Oral decongestants are also contraindicated in patients with hypertension, coronary artery disease, and history of bleeding strokes.

Treatments that may help with symptoms include simple pain medication and medications for fevers such as ibuprofen and acetaminophen (paracetamol). It, however, is not clear if acetaminophen helps with symptoms. It is not known if over the counter cough medications are effective for treating an acute cough. Cough medicines are not recommended for use in children due to a lack of evidence supporting effectiveness and the potential for harm. In 2009, Canada restricted the use of over-the-counter cough and cold medication in children six years and under due to concerns regarding risks and unproven benefits. The misuse of dextromethorphan (an over-the-counter cough medicine) has led to its ban in a number of countries. Intranasal corticosteroids have not been found to be useful.

In adults short term use of nasal decongestants may have a small benefit. Antihistamines may improve symptoms in the first day or two; however, there is no longer-term benefit and they have adverse effects such as drowsiness. Other decongestants such as pseudoephedrine appear effective in adults. Ipratropium nasal spray may reduce the symptoms of a runny nose but has little effect on stuffiness. The safety and effectiveness of nasal decongestant use in children is unclear.

Due to lack of studies, it is not known whether increased fluid intake improves symptoms or shortens respiratory illness, and there is a similar lack of data for the use of heated humidified air. One study has found chest vapor rub to provide some relief of nocturnal cough, congestion, and sleep difficulty.

First-generation antihistamine has been suggested as first-line therapy to treat post-nasal drip.

No medications or herbal remedies have been conclusively demonstrated to shorten the duration of infection. Treatment thus comprises symptomatic relief. Getting plenty of rest, drinking fluids to maintain hydration, and gargling with warm salt water are reasonable conservative measures. Much of the benefit from treatment is, however, attributed to the placebo effect.

Treatment is not usually necessary in asymptomatic cases, since most fusions will separate naturally over time, but may be required when symptoms are present. The standard method of treatment for labial fusion is the application of topical estrogen cream onto the areas of adhesion, which is effective in 90% of patients. In severe cases where the labia minora are entirely fused, causing urinary outflow obstruction or vaginal obstruction, the labia should be separated surgically. Recurrence after treatment is common but is thought to be prevented by good hygiene practices. One study has shown that betamethasone may be more effective than estrogen cream in preventing recurrence, with fewer side effects.

There is a vaccine for FHV-1 available (ATCvet code: , plus various combination vaccines), but although it limits or weakens the severity of the disease and may reduce viral shedding, it does not prevent infection with FVR. Studies have shown a duration of immunity of this vaccine to be at least three years. The use of serology to demonstrate circulating antibodies to FHV-1 has been shown to have a positive predictive value for indicating protection from this disease.

It is not lethal in nature and is responsive to tetracycline or ciprofloxacin. Surgical treatment include rhinoplasty. However, if left untreated the disease can lead to sepsis, bleeding, or other chronic conditions that can be fatal.

Reduction of hypertrophied turbinates, correction of nasal septum deviation, removal of polyps, sectioning of the parasympathetic secretomotor fiber to nose (vidian neurectomy) for controlling refractory excessive rhinorrhea.

There is some low quality evidence suggesting that mometasone may lead to symptomatic improvement in children with adenoid hypertrophy.

Surgical removal of the adenoids is a procedure called adenoidectomy. Carried out through the mouth under a general anaesthetic, adenoidectomy involves the adenoids being curetted, cauterised, lasered, or otherwise ablated. Adenoidectomy is most often performed because of nasal obstruction, but is also performed to reduce middle ear infections and fluid (otitis media). The procedure is often carried out at the same time as a tonsillectomy, since the adenoids can be clearly seen and assessed by the surgeon at that time.

The management of rhinitis depends on the underlying cause.

For allergic rhinitis, intranasal corticosteroids are recommended. For severe symptoms intranasal antihistamines may be added.

The avoidance of inciting factors such as sudden changes in temperature, humidity, or blasts of air or dust is helpful.

Intranasal application of antihistamines, corticosteroids, or anticholinergics may also be used for vasomotor rhinitis. Intranasal cromolyn sodium may be used in patients older than two years.

Astelin (Azelastine) "is indicated for symptomatic treatment of vasomotor rhinitis including rhinorrhea, nasal congestion, and post nasal drip in adults and children 12 years of age and older."

The first line of treatment for nasal polyps is topical steroids. Steroids decrease the inflammation of the sinus mucosa to decrease the size of the polyps and improve symptoms. Topical preparations are preferred in the form of a nasal spray, but are often ineffective for people with many polyps. Steroids by mouth often provide drastic symptom relief, but should not be taken for long periods of time due to their side effects. Because steroids only shrink the size and swelling of the polyp, people often have recurrence of symptoms once the steroids are stopped. Decongestants do not shrink the polyps, but can decrease swelling and provide some relief. Antibiotics are only recommended if the person has a co-occurring bacterial infection.

In people with nasal polyps caused by aspirin or NSAIDs, avoidance of these medications will help with symptoms. Aspirin desensitization has also been shown to be beneficial.

Avoiding turbinectomy or using turbinate-sparing techniques may prevent ENS.
