What type of drug is diphenhydramine?
sedating antihistamine (traditional)
What is the mechanism of action for diphenhydramine?
1. antagonizes the effects of H1 receptor sites
2. Has CNS depressant and anticholinergic effects (drying--> dry mouth, difficulty
urinating, constipation, changes in vision)
3. It is more effective than nonsedating antihistamines
4. may cause drowsiness
5. works peripherally and centrally
Why would someone take diphenhydramine?
-relief of allergic symptoms
Nursing Implications (A,I,L,T) for diphenhydramine?
1. Assessment:
-sedation, urticaria, potency of airway, nausea, bowel sounds, degree of itching, skin
rash, inflammation
2. Implementation:
-when given oral, give with meals or milk
3. Labs:
-may affect allergy testing
,4. Teaching:
-avoid OTC cough and cold products while breast feeding
-avoid driving due to drowsiness
-hard candy or gum for dry mouth
-avoid other CNS depressants while on this med.
what medication class does fexofenadine, loratadine, and cetirizine belong to?
non sedating antihistamines
what is the mechanism of action for fexofenadine, loratadine, and cetirizine?
-antagonizes the effects of H1 receptors
-works peripherally to block the actions of histamine (leads to less CNS adverse effects)
-longer duration of action
why would someone take fexofenadine, loratadine, and cetirizine?
relief of seasonal allergies
nursing implications (A,I,L,T) for fexofenadine, loratadine, and cetirizine
1. Assessment:
-allergy symptoms
-lung sounds
-secretions and sputum
2. Implementation:
-maintain adequate fluid intake
-administer with food or milk
3. Labs:
-can cause false skin allergy tests (Allegra)
,4. Teaching:
-take medication as directed, if symptoms persist call healthcare professional
what medication class does pseudoephedrine belong to?
adrenergics (oral decongestants)
mechanism of action for pseudoephedrine?

-produces vasoconstriction in the respiratory tract
-fight or flight effects
-no rebound congestion
why would someone take pseudoephedrine?
-to reduce nasal congestion, hyperemia, and swelling in the nasal passages
Nursing implications (A,I,L,T) for pseudoephedrine?
1. assessment:
-congestion, bronchial secretions, and lung sounds
-monitor pulse and BP
2. Implementation:

3. Labs:
-N/A
4. Teaching:
-take as prescribed

, -notify healthcare professional if nervousness, slow or fast HR, breathing difficulties,
hallucinations, or seizures occur
what medication class does beclomethasone dipropionate and fluticasone belong
to?
corticosteroid (nasal decongestant)
what is the mechanism of action for beclomethosone dipropionate and
fluticasone?
-locally acting anti-inflammatory and immune modifier medications that are potent
why would someone take beclomethasone dipropionate and fluticasone?
-anti-inflammatory effects
-seasonal allergies
-decreases symptoms of allergic and nonallergic rhinitis
nursing implications (a,I,L,T) for beclomethasone dipropionate and fluticasone?
1. assessment:
-signs and symptoms of hypersensitivity reactions (rash, pruritus swelling of face and
neck, dyspnea)
2. Implementation:
-should be given decongestant 5-15 min before using a corticosteroid nasal spray
3. Labs:
-need periodic adrenal function tests
4. Teaching:
-take medication as prescribed
-stop if you see signs of anaphylaxis
