(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

bowel sounds, degree of itching, skin rash,
inflammation
2. Implementation:
-when given oral, give with meals or milk

what medication class does non sedating antihistamines
fexofenadine (Allegra), loratadine
(Claritin), and cetirizine (Zyrtec)
belong to?
what is the mechanism of action for -antagonizes the effects of H1 receptors
fexofenadine (Allegra), loratadine -works peripherally to block the actions of
(Claritin), and cetirizine (Zyrtec)? histamine (leads to less CNS adverse effects)
-longer duration of action
why would someone take relief of seasonal allergies
fexofenadine (Allegra), loratadine
(Claritin), and cetirizine (Zyrtec) ?
, nursing implications (A,I,L,T) for 1. Assessment:
fexofenadine (Allegra), loratadine -allergy symptoms
(Claritin), and cetirizine (Zyrtec) -lung sounds
-secretions and sputum
2. Implementation:
-maintain adequate fluid intake
-administer with food or milk

-can cause false skin allergy tests (Allegra)
4. Teaching:
-take medication as directed, if symptoms persist
call healthcare professional

pseudoephedrine (Sudafed) belong
to?
mechanism of action for -stimulates alpha and beta adrenergic receptors
pseudoephedrine (Sudafed)? -produces vasoconstriction in the respiratory tract
-fight or flight effects
-no rebound congestion
why would someone take -to reduce nasal congestion, hyperemia, and
pseudoephedrine (Sudafed)? swelling in the nasal passages
