Main Page | Risk Factors | Symptoms | Diagnosis | Treatment | Screening | Reducing Your Risk | Talking to Your Doctor | Resource Guide
The information provided here is meant to give you a general idea about each of the medications listed below. Only the most general side effects are included, so ask your doctor if you need to take any special precautions. Use each of these medications as recommended by your doctor, or according to the instructions provided. If you have further questions about usage or side effects, contact your doctor.
There are many types of medications—both over-the-counter and prescription—that can be used to treat symptoms of allergic rhinitis, and each class of medication functions differently in the body. However, once a definite diagnosis of allergic rhinitis is made, the first-line treatment of choice is nasal corticosteroid spray, as it is has been shown to be the most effective with the fewest side effects. Ask you doctor which medications may offer prevention of allergic rhinitis symptoms.

Prescription Medications
Antihistamines
Common names include:
- Fexofenadine (Allegra)
- Desloratadine (Clarinex)
- Levocetirizine (Xyzal)
Antihistamines help stop or reduce the production of histamine, a chemical that is released when the immune system reacts to an allergen. The release of histamine leads to the symptoms of allergic rhinitis.
Possible side effects include:
- Drowsiness
- Lightheadness
- Blurry vision
- Change in ability to think clearly
- Dry mouth, nose, or throat
- Gastrointestinal upset, stomach pain, or nausea
- Increased appetite and weight gain
- Thickening of mucus
- Increased effects in people with kidney disease due to slower removal from the body
Nasal antihistamine sprays are also available, such as azelastine (Astelin).
Oral Decongestants and Antihistamine Combinations
Common names include:
- Fexofenadine and pseudoephedrine (Allegra-D)
- Acrivastine and pseudoephedrine (Semprex-D)
- Azatadine and pseudoephedrine (Trinalin)
Decongestants help to narrow the blood vessels, which results in a clearing of nasal congestion. Antihistamines help stop or reduce the production of histamine, a chemical that is released when the immune system reacts to an allergen.
Possible side effects of the oral decongestant/antihistamine combinations include:
- Drowsiness
- Cough
- Increase in blood pressure
- Headache
- Nervousness, difficulty sleeping
- Nausea
- Rapid heart rate
Nasal Corticosteroid Spray
Common names include:
- Beclomethasone (Beconase)
- Fluticasone (Flonase)
- Triamcinolone (Nasacort)
- Mometasone (Nasonex)
- Budesonide (Rhinocort)
Nasal corticosteroids are sprayed or inhaled into the nose to help relieve the stuffy nose and discomfort of allergies.
Possible side effects include:
- Burning, dryness, or other irritation inside the nose (mild, lasting only a short time)
- Increase in sneezing
- Irritation of the throat
Nasal Mast Cell Stabilizer
Common name: Cromolyn sodium (Intal)
Cromolyn is unique in that it is preventative. It changes the body's immunological response to allergens. It is most effective when used before coming into contact with substances that cause allergies or before allergy season. Cromolyn may be used alone or with other medicines.
Possible side effects include:
- Burning, stinging, or irritation inside of nose
- Flushing
- Increase in sneezing
Leukotriene Inhibitor
Common name: Montelukast (Singulair)
This medication is also used to prevent allergy symptoms. It works by decreasing how many leukotrienes (chemicals) the body creates in response to an allergen.
Possible side effects include:
- Flu-like symptoms
- Nervousness
- Headache and stomach ache
- Nausea and vomiting
- Nasal congestion
The US Food and Drug Administration (FDA) is investigating to see if there is a link between taking this medication and having suicidal thoughts. If you are taking Singulair, do not stop right way. Talk to your doctor first.
Over-the-Counter Medications
Antihistamines
The following medications are available without a prescription. Many of these are older or first-generation antihistamines. However, both loratadine and cetirizine are nonsedating second-generation antihistamines.
- Diphenhydramine (Benadryl)
- Chlorpheniramine (Chlor-Trimeton)
- Brompheniramine (Dimetane)
- Dexbrompheniramine and pseudoephedrine (Drixoral)
- Loratadine (Claritin)
- Cetirizine hydrochloride (Zyrtec)
- Clemastine (Tavist)
- Chlorpheniramine and phenylpropanolamine (Triaminic Allergy)
Antihistamines help stop or reduce the production of histamine, a chemical that is released when the immune system reacts to an allergen. The release of histamine leads to the symptoms of allergic rhinitis.
Possible side effects include:
- Drowsiness (loratadine and zyrtec are nonsedating.)
- Slowed reaction time
- Dry mouth
Oral Decongestants
Common names include:
- Pseudoephedrine-containing products (eg, Sudafed, Actifed, Drixoral)
Decongestants help to narrow the blood vessels, which results in a clearing of nasal congestion. One possible side effect is an increase in blood pressure.
Nasal Decongestants
Common names include:
- Afrin
- Neo-Synephrine
Nasal sprays help relieve the stuffy nose and discomfort of allergies.
Possible side effects include:
- Burning, stinging, or irritation inside of nose
- Flushing
- Increase in sneezing
- Rebound (increased nasal congestion) if nasal decongestant sprays are used for more than three days
Saline Nasal Spray
Salinex is a nasal spray that contains a saltwater solution to rinse your nose and help relieve mild congestion, loosen mucus, and prevent crusting. Though it can be useful for relieving symptoms of a stuffy nose and has no side effects, saline can't prevent allergy symptoms from occurring, as some other allergy treatments can.
Special Considerations
Whenever you are taking a prescription medication, take the following precautions:
- Take them as directed—not more, not less, not at a different time.
- Do not stop taking them without consulting your doctor.
- Don’t share them with anyone else.
- Know what effects and side effects to expect, and report them to your doctor.
- If you are taking more than one drug, even if it is over-the-counter, be sure to check with a physician or pharmacist about drug interactions.
- Plan ahead for refills so you do not run out.
