Treatment

If rhinitis is caused by non-allergic conditions, particularly if there are accompanying symptoms indicating a serious problem, the doctor should treat any underlying disorders. If rhinitis is caused by medications, such as decongestants, the patient may need to stop taking them or find alternatives.

Preventing the Onset of Allergy Attacks

Patients with chronic allergic rhinitis may require daily medications. Patients with severe seasonal allergies should start medications a few weeks before the pollen season and continue taking them until the season is over. Effective medications include:

• Drugs that reduce the inflammatory response are important for preventing severe allergic rhinitis. Nasal corticosteroids (commonly called steroids) are now considered to be the most effective measure for preventing allergy attacks. Other anti-inflammatory drugs include leukotriene-antagonists and nasal cromolyn.
• Antihistamine tablets relieve sneezing and itching and can prevent nasal congestion before an allergy attack. Many brands are available by prescription and over-the-counter.
• Immunotherapy ("allergy shots") may be considered for patients with severe seasonal allergies that do not respond to treatment. It may also prevent asthma and the development of new allergies in children. Many experts now recommend immunotherapy for people with both asthma and allergies. Newer immunotherapeutic approaches using specially designed antibodies and vaccines are also showing promise.

All drug treatments have side effects, some very unpleasant and, in rare cases, serious. Patients may need to try different drugs until they find one that relieves symptoms without producing excessively distressing side effects.

Treating Nasal Symptoms of Allergic Rhinitis

Because seasonal allergies generally last only a few weeks, most doctors do not recommend the more potent prescription treatments for children. It is important for parents to determine if the child is actually under severe distress and that the parent is not simply responding to their own anxiety when they hear the child snorting or snoring. Prescription drugs are required only in severe cases. However, in children with both asthma and allergies, treatments for allergic rhinitis may also improve asthmatic symptoms.

Treating Mild Allergy Attacks. Mild allergy attacks usually require little more than reducing exposure to allergens and using a nasal wash. Dozens of treatments are available for allergic rhinitis. Many are available over-the-counter, but some require a prescription. They include the following:

• Nasal washes
• Decongestants that relieve nasal congestion and itchy eyes
• Decongestant/antihistamine combinations

Due to side effects, decongestants should not be used in children ages 14 years or younger. Also, overuse of nasal decongestions can actually worsen sinus congestion.

Treating Severe Allergic Rhinitis. Patients with chronic allergic rhinitis, particularly if they also have asthma, may require daily medications. These drugs include:

• Antihistamines. The newer non-sedating antihistamines -- such as cetirizine (Zyrtec), loratadine (Claritin), fexofenadine (Allegra), or desloratadine (Clarinex) -- cause less drowsiness than older antihistamines, such as Benadryl. Some of the newer drugs, such as Zyrtec and Clarinex, may also relieve nasal congestion.
• Anti-inflammatory drugs. Nasal corticosteroids are now considered to be the most effective measure for preventing allergy attacks. They are recommended for patients with very severe allergies that do not respond to antihistamines.
• Leukotriene-antagonists and nasal cromolyn may be beneficial in specific cases of allergies
• Immunotherapy ("allergy shots") works well for many patients with severe allergies. It is also proving to reduce asthma symptoms and the use of asthma medications in patients with known allergies.

Treating Itchy Eyes

Itching and redness in the eyes sometimes respond to oral antihistamines. Eye drops, however, provide faster relief, and a combination of the two may be best. The following are eye drops for itchy eyes. Others are also available. Individual responses vary, and patients need to find which specific treatment works best for them.

• Antihistamine eye drops: azelastine (Optivar), olopatadine (Patanol), ketotifen (Zaditor), levocabastine (Livostin) for relief of both nasal symptoms and itchy red eyes
• Decongestant eye drops: phenylephrine (Allergan Relief), naphazoline (Naphcon, Opcon-A, VasoClear), tetrahydrozoline (Murine Plus, Visine)
• Combination decongestant/antihistamine: Visine A.
• Corticosteroids: loteprednol (Lotemax, Alrex), pemirolast (Alamast).

General Side Effects and Warning.

• All eye drops can cause stinging, and some may result in headache and congestion.
• No one should continue taking eye drops if they experience pain, changes in vision, worsened redness, or irritation, or if the condition lasts more than 3 days.
• Do not touch the tip of the device to the eye or touch other surfaces with it. Replace the cap after using. Discard any solution that changes color or becomes cloudy.
• People who have heart disease, high blood pressure, an enlarged prostate gland, or glaucoma should talk to their doctor before taking these types of eye drops.
