  • Allergic Rhinitis

Allergic rhinitis can negatively impact an individual’s quality of life by impairing concentration and causing fatigue and sleep disturbances. Allergic rhinitis (AR), which can be classified as seasonal (hay fever) or perennial, can negatively impact an individual’s quality of life by impairing concentration and causing fatigue and sleep disturbances, depending on the severity and frequency of symptoms.1-3
Seasonal allergic rhinitis (SAR), which occurs in spring, summer, and early fall, is caused by allergic sensitivity to pollen (from trees, grasses, or weeds) or mold spores that are airborne.1,2 Perennial allergic rhinitis (PAR) typically causes year-round symptoms due to hypersensitivity to allergens such as dust mites, animal dander, cockroaches, and mold spores.1-4
Prior to initiation of pharmacologic therapy, a patient’s medical and medication history, possible allergens, and symptoms (including severity) should be thoroughly evaluated. The patient’s preferred treatment, its potential adverse effects, its cost, and its dosing frequency should be assessed. Normally, AR symptoms manifest in patients older than 2 years and are especially prevalent in patients 18 to 64 years of age (Table 1).1

AR is associated with many complications, including otitis media, sinusitis, recurring sore throat, cough, headache, disruption in sleep patterns, sleep apnea, depression, fatigue, anxiety, irritability, poor school or work performance, and impaired cognitive function.1-3 It is important to note that according to the American Academy of Allergy, Asthma & Immunology, an estimated 33% of individuals with rhinitis do not have allergies.5 These patients are classified as having non-AR, and the causes of symptoms include hormonal changes (eg, pregnancy, puberty, thyroid conditions), structural defects (eg, septal deviation, adenoid hypertrophy), and lesions (eg, nasal polyps and neoplasms).1-3,6
Pharmacists are in a pivotal position to counsel patients on pharmacologic agents (eg, beta-blockers, oral contraceptives, clonidine, angiotensin-converting enzyme inhibitors, acetylsalicylic acid and other nonsteroidal anti-inflammatory drugs, topical decongestants) that may increase the risk for rhinitis, and pharmacists can make recommendations to manage this effect.1-3,6
Nonprescription Treatments
Many treatment options are available to manage or reduce AR symptoms.1 The treatment of SAR and PAR is typically the same; however, individuals with PAR may be able to alleviate or decrease symptoms through environmental control (eg, elimination of dust mites, mold, or pet dander). While the ideal option for the management of AR is avoidance of allergy triggers, this is not always a practical approach; therefore, the use of 1 or more pharmacologic agents may be needed to reduce or prevent AR symptoms.
Treatment of AR may include a combination of environmental control measures and allergen avoidance, pharmacologic therapy, and immunotherapy.3,6 Patients may have to try several therapy options, including a combination of therapies, before finding an effective treatment. A host of nonprescription products are available for self-management of AR symptoms. These products include oral and ocular antihistamines; oral, nasal, and ocular decongestants; and mast cell stabilizers.1 To meet the needs of the adult and pediatric patient populations, single-entity and multiple-ingredient products are available in various dosage forms, including immediate- and sustained-release formulations, tablets, capsules, oral-disintegrating and chewable tablets, and flavored liquids.
Recently, several new products have become available, including Mucinex Allergy (Reckitt Benckiser), which contains the antihistamine fexofenadine in a once-a-day formulation. In addition, the nasal spray triamcinolone acetonide, which had been available only in prescription form, was cleared for FDA approval as Nasacort Allergy 24HR (Chattem), making it the first corticosteroid to be granted OTC approval.7,8 It is approved for patients 2 years and older to provide relief of nasal congestion, sneezing, rhinorrhea, and itchy nose.8 In March 2014, McNeil announced the new dissolving tablet formulation of Zyrtec, which can be taken without water.9
Antihistamines are standard therapy for providing symptomatic relief of AR and are indicated for the relief of itching, sneezing, and rhinorrhea symptoms.1 First-generation antihistamines such as diphenhydramine are often associated with drowsiness/sedation, impaired mental alertness, and anticholinergic effects, so patients should be advised to use caution when taking these products.1
Second-generation nonprescription antihistamines (nonsedating antihistamines) available in nonprescription products include loratadine, cetirizine, and fexofenadine.1 Second-generation antihistamines are widely used and preferred because they typically do not cause significant drowsiness and are rapidly absorbed after oral administration, with peak plasma concentrations occurring after 1 to 3 hours.1
Because AR patients often experience nasal congestion, some patients elect to use nonprescription decongestants such as pseudoephedrine and phenylephrine in combination with antihistamines.1 These agents are indicated for temporary relief of nasal and eustachian tube congestion as well as cough associated with postnasal drip.1 Insomnia, nervousness, and tachycardia are examples of the most prevalent adverse effects of oral decongestants. They may also exacerbate medical conditions that are sensitive to adrenergic stimulation, such as hypertension, diabetes, coronary artery disease, prostatic hypertrophy, and elevated intraocular pressure.1
Because use of topical decongestants for more than 3 to 5 days could result in rhinitis medicamentosa (rebound congestion), patients should be advised to use these products for no longer than the recommended duration of time.1 Because some combination allergy medications include an antihistamine and a decongestant, patients should be advised to only use combination products when warranted, to avoid unnecessary drug use. Pharmacists are in a critical position to identify individuals who may be at risk for drug–drug interactions or may have contraindications to the use of antihistamines and decongestants.
Cromolyn Sodium
The nasal spray cromolyn sodium is approved for patients 5 years and older and is indicated for preventing and treating symptoms associated with AR.1 Intranasal cromolyn is not associated with any known drug interactions.1,10 Cromolyn sodium should be administered as 1 spray in each nostril 3 to 6 times daily, and treatment is more effective if initiated at least a week before seasonal symptoms occur.1 Symptomatic relief usually becomes apparent within 3 to 7 days, and therapy should be continued for at least 2 to 4 weeks to achieve optimal effect.1 The most common adverse effect is sneezing, and other adverse effects may include burning and stinging sensations in the nasal area.1,10
Ocular Allergies
If a patient is experiencing watery and itchy eyes due to allergies, ocular antihistamine products, such as pheniramine maleate and antazoline phosphate, are available in combination with the decongestant naphazoline.11 The most prevalent adverse effects associated with ophthalmic antihistamines include burning, stinging, and discomfort upon instillation.11
Ketotifen 0.025% is the only nonprescription antihistamine ophthalmic product on the market for the relief of ocular itching without the use of a decongestant.12,13 Ketotifen is classified as a noncompetitive histamine1-receptor antagonist and mast cell stabilizer that inhibits the release of mediators from cells involved in hypersensitivity reactions and is approved for use in patients 3 years and older for temporary relief of itchy eyes due to exposure to ragweed, pollen, grass, animal hair, and dander.12,13 The recommended dosage is 1 drop instilled into the affected eye(s) every 8 to 12 hours, but no more than twice daily.12,13 It is classified as pregnancy category C.11 Common adverse reactions include headache, dry eyes, and rhinitis.12,13 Ketotifen is not indicated for treatment of contact lens–related inflammation, and individuals who wear contacts should be instructed to wait at least 10 minutes before inserting their lenses after instillation of ketotifen.12,13
Patient Counseling
During counseling, patients should always be advised to adhere to the manufacturer’s directions and recommended dosages and be aware of potential adverse effects (Table 2). Patients not experiencing any relief after self-treatment should be advised to seek further medical evaluation from their primary health care provider to discuss other treatment options. In addition to providing drug information to patients, pharmacists can suggest various nonpharmacologic measures, such as using nasal saline solutions to relieve nasal irritation and dryness or using nonmedicated nasal strips to help relieve congestion.3,4
Table 2: Patient Counseling Tips

  • Patient adherence is vital to controlling symptoms, so it is important to adhere to the recommended dosage of the selected product.
  • Always consult your primary health care provider about treatment options if allergy symptoms return or worsen.
  • To prevent or control symptoms, take allergy medications as soon as symptoms begin or before exposure to a known allergen.
  • Prior to using any nonprescription product for allergic rhinitis, pregnant or lactating females, patients with preexisting medical conditions (eg, hypertension, diabetes, elevated intraocular pressure, chronic bronchitis, prostatic hypertrophy), or individuals taking other medications (eg, monoamine oxidase inhibitors, central nervous system depressants) should seek advice from their primary health care provider.

  • Due to potential sedating effects, patients should avoid the use of alcohol when taking antihistamine products.
  • For environmental control to decrease allergy symptoms, wash bedding in hot water every week, regularly vacuum carpets and upholstery, use allergy covers on pillows and mattresses, maintain a relative humidity level of 40% to 50% in the home to reduce mold, keep car and home windows closed (especially when pollen and mold levels are elevated), and routinely check pollen and mold counts in the local area.
  • When possible, plan outdoor activities at times of the day that are not during peak pollen production, which occurs between 5:00 am and 10:00 am.

2. Case report

In 2015, a 45 year old female non-smoker, presented to our office, requesting a comprehensive assessment and holistic management of her multiple medical conditions. She had recently relocated from New York to Texas, hoping that the dryer climate would help to improve upper respiratory symptoms (non-productive chronic cough, mucus accumulation and post-nasal drip), that were adversely affecting her quality of life.

Past medical history revealed a classic atopic march – childhood atopic dermatitis, food allergies, allergic rhinitis and asthma, all of which had persisted into adulthood. She also reported suffering from bronchitis throughout her life, recurrent pneumonia and more recently an eleven month episode of viral pleurisy. At the time of her visit, chronic conditions included moderate-to-severe asthma, stable chronic bronchitis (6–8 exacerbations/year), food and medication allergies, chronic sinusitis with nasal polyps, celiac disease, inflammatory bowel syndrome (IBS) and Raynaud’s syndrome.

Medications included monthly omalizumab (Xolair®, Genentech) and allergy immunizations for pollens, molds and dust mites. In addition she took daily montelukast sodium (Singulair®, Merck), azelastine nasal spray, certirizine, OTC acetaminophen 325mg/guaifenesin 200mg/phenylephrine 5mg (Mucinex® Sinus-Max® Pressure & Pain Caplets, Reckitt Benckiser) and used a proprietary isotonic saline nasal rinse, every other day. She also had a levalbuterol inhaler, but had not used it since moving to Texas.

Clinical chemistry revealed an IgG level of 466 mg/dL, with sluggish response to pneumococcal stimulation indicating mild-moderate hypogammaglobulinemia (reference range 700–1600mg/dL). Given her recurrent infections we concluded she likely has Primary Immunodeficiency Disease (PIDD) with hypogammaglobulinemia. Monthly intravenous immunoglobulin (IGIV) therapy was commenced, but ultimately discontinued due to severe side effects, including crippling migraines, irrespective of the product used, concentration, osmolarity and speed of infusion – all factors known to influence side-effects.

Although she had been taking a low-dose guaifenesin containing multi-symptom OTC cold and sinus medication for 10 years, we recommended that she commence higher dose guaifenesin (Mucinex®, Reckitt Benckiser) 600 mg, twice daily to relieve the thick mucus she felt was constantly in the back of her throat and was unable to expectorate.

Since starting the higher dose of guaifenesin, she reports that post nasal drip is significantly reduced, her cough is improved and mucus is much less viscous and easier to expectorate. No further sinus infections have been reported and the nasal congestion resulting from the nasal polyps is less problematic.

In parallel, we have been able to discontinue allergy shots and omalizumab with no relapse and perceived significant improvement in quality of life. In total, she has been using guaifenesin on an almost daily basis for almost ten years – the last 3 years at a higher dose. Although warned about the potential for nausea, the patient denies any treatment-related side-effects. Temporary cessation of guaifenesin has resulted in recurrence of mucus related symptoms and cough within 2–3 days, so at this time the patient has no plans to discontinue the current treatment.

With all the flowers and trees blooming this spring and summer, seasonal allergies are at their peak as well. Whether you experience allergic symptoms every year around this time, or if this is your first year, you already know they can be quite a nuisance!

Trees, weeds, grasses, or blooming flowers can release pollen into the air, which in turn can cause hay fever. Hay fever or allergic rhinitis are fancy terms for your typical seasonal allergy symptoms.

Most of the time you can save yourself a visit to your doctor’s office (and the co-pay that goes with it) by treating your symptoms with one of the many different medications that are now available over-the-counter without a prescription.

If you are unsure of which medication to use, asking your pharmacist can help narrow your choices down. However, it’s important to let your pharmacist know some important information so that they can suggest the best over-the-counter treatment for you:

  • Any allergies
  • A list of medications you are currently taking, including over-the-counter drugs, vitamins, minerals, herbs, and samples from your doctor
  • What medications you have already tried (if any)

What types of medications are used for seasonal allergies?

Seasonal allergy medications come in many forms, including:

  • Oral tablets, capsules, liquids
  • Lozenges
  • Nasal sprays
  • Throat sprays
  • Eye drops

What classes of medications are available OTC to treat seasonal allergies?

Most over-the-counter medications treat different allergy symptoms, like runny nose, itchiness, or cough. Some categories include:

  • Antihistamines
  • Decongestants
  • Cough suppressants
  • Expectorants
  • Nasal steroids

Still a little lost? Here’s a quick overview of the basic OTC allergy meds.
Antihistamines are a great go-to medication to alleviate many of the symptoms associated with seasonal allergies—particularly sneezing, runny nose, nasal drainage, and itchiness. Antihistamines work by drying up excess bodily secretions and blocking histamine, a natural substance released by the body during allergic reactions.

Some OTC antihistamines include:

  • Claritin (loratadine)
  • Zyrtec (cetirizine)
  • Allegra (fexofenadine)
  • Benadryl (diphenhydramine)

Decongestants are used to relieve nasal congestion, as well as the pressure and pain you may feel in your head or sinuses from seasonal allergies. Decongestants work by narrowing the blood vessels that are causing nasal congestion which results in the usual flow of air allowing a person to breathe normally.

Some OTC decongestants include:

  • Sudafed (pseudoephedrine)
  • Sudafed PE (phenylephrine)
  • Afrin (oxymetazoline)

Decongestants may also be available in combination with antihistamines in medications like Allegra-D (fexofenadine/pseudoephedrine) or Claritin-D (loratadine/pseudoephedrine).

Cough suppressants are best used to alleviate a dry, non-productive, nagging cough that tends to linger. They work to control your cough by blocking the cough reflex. Delsym (dextromethorphan) is a common example.

Expectorants are used for chest congestion associated with a productive cough containing mucus. They work by thinning and loosening the mucus that causes chest congestion. Mucinex (guaifenesin) is a common example.

Nasal steroids can be used to treat not only the nasal congestion associated with seasonal allergies, but one in particular, Flonase Allergy Relief, is also approved to ease runny and itchy nose, sneezing, and watery and itchy eyes. Nasal steroids work by decreasing inflammation to help relieve nasal congestion.

The nasal steroids currently available OTC are:

  • Flonase Allergy Relief
  • Nasacort Allergy 24HR
  • Is it an Allergy …or a Cold? How to tell the difference


    Spring and early summer have brought a round of sniffles and unrelenting cough. High pollen counts and dry weather can make it difficult to distinguish if your symptoms are due to allergies or a cold. While many cold and allergy symptoms overlap, there are some defining characteristics that can help you tell the difference and determine the best treatment method.

    One common overlapping symptom is chest congestion with a phlegmy cough. Allergies can also cause chest congestion and a bad cough due to mucus from the nasal sinuses dripping down the back of the throat (post-nasal drip). If you find yourself clearing your throat, followed by chest congestion, coughing, and thick mucus during dry, seasonal allergy weather with no fever or muscle aches, it is most likely an allergy. However, if these same symptoms present with a fever and/or muscle aches, lethargy or fatigue, you likely have a cold or flu.


    When present, features distinguishing an infection from an allergy are a fever greater than 100°F measured orally and/or body aches. Symptoms common to both colds and allergies are: sore throat, stuffy nose, sneezing, and post-nasal drip. Viruses, the cause of colds, cannot be killed by antibiotics, like a “Z-pack.” Colds come on quickly and can include a mild fever, but usually resolve completely in one to two weeks once your body has fought off the virus. A fever of greater than 100 degrees Fahrenheit or severe body aches indicate you may have the flu, not a cold, and should contact your primary care provider.


    When an allergen or infectious particle attaches to your mucus membranes, your body’s inflammatory response creates an immunologic response. Additional mucus is made to catch and flush away the virus, but this can cause serious congestion. Decongestants like Mucinex-D can be taken during the day to loosen this build-up of thick mucus. Thin, runny, watery discharge requires an anti-histamine (eg: Zyrtec, Allegra) instead of Mucinex-D. If your cough persists while sleeping, Mucinex DM can be used as a cough suppressant at bedtime.

    A natural and very effective treatment option is to use a nasal saline rinse (like NeilMed sinus, Simply Saline, or CVS brand) which can aid your body in flushing the virus or allergens (pollen, dust, etc.) out of your sinus and nasal passages. This treatment should be followed within 30 minutes by a nasal spray (like Flonase), which will shrink nasal passages. Clearing and shrinking nasal passages rids the sinuses of the offending agent. With cleared sinuses, watery eyes drain easily through cleared passages and post-nasal drip will decrease since the nasal rinse has cleared most of the debris from the sinuses. Without post-nasal drip, chest congestion is markedly reduced.

    This regimen should be administered 2-3 times daily as dictated by symptoms.


    An important thing to keep in mind is that your body can best fight infection when it is well rested and well hydrated. Allowing time for extra sleep during a cold, as well as drinking eight ounces of water or herbal caffeine-free tea every few hours and eating well, prepares your body with the energy and resources needed to combat a virus. In the winter, humidity levels in New England plummet, drying out nasal passages and creating the optimal environment for virus proliferation. Therefore, using a humidifier with warm mist in the bedroom at night will relieve the irritation and soreness of the throat and nose with moisture. Ideally, it is preferable to have a humidifier in your workspace as well.

    Increasing your intake of Vitamin C to approximately 1000 milligrams (mg) per day for the duration of your cold can decrease the length of your sickness. These methods can help alleviate your cold symptoms and help you feel more functional as your body fights the virus.

    If your symptoms have not gotten significantly better after two weeks, you may have developed a bacterial infection that needs a doctor’s attention or your symptoms may be more allergic in nature (even in the winter…think dust!).


    Allergic symptoms are the result of your body interacting with inhaled allergens – environmental triggers that cause an immune system reaction. Immune cells in your body release chemicals called histamines that cause sinus swelling, which causes eye itchiness, mucus accumulation, post-nasal drip, and cough. The added mucus and airway irritation can also cause symptoms similar to asthma, such as tightness in the chest or difficulty breathing. While these symptoms can also be present in colds, most allergic symptoms occur seasonally and are long-lasting – it seems like a cold that won’t go away.

    Antihistamine medications like Zyrtec, Claritin, and Allegra can help alleviate some of these allergic symptoms. Many people experience relief using these over-the-counter medications along with the nasal rinse followed by nasal spray mentioned above. Often even the non-drowsy formulations cause substantial drowsiness the following day. Therefore, it is recommended that they be taken in the early evening, and then as needed during the day. If you have tried these methods and are still suffering from allergic symptoms, talk to your primary care provider about prescription medication options, like Singulair.

    When combating allergies, it is also important to prevent exposure as much as possible. For seasonal allergies, this can be done by keeping the windows closed, running a powerful air-cleaning HEPA filter in your home, and avoiding spending time outdoors when pollen counts are high. To further decrease allergens inside, take a shower in the evening or at night to wash off allergens stuck to your skin and hair that can be transferred to your bed. Also, change your clothes as soon as you come inside to avoid spreading allergens in your home. Using medications and avoiding allergens during allergy season can really make a difference!

    With so many overlapping symptoms, it is easy to see how a cold and allergies could be confused. The attached graphic is intended to succinctly summarize this article. If you have any questions about your symptoms or treatment, please feel free to get in touch with our office, Enhanced Medical Care.

    Fexofenadine is an antihistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.
