Study Notes
Antihistamines
- Desloratadine selectively binds to peripheral H1 receptors, producing antihistamine effects.
- First-generation antihistamines like diphenhydramine, brompheniramine, and clemastine can cause sedation.
- Elderly clients may be at higher injury risk when taking antihistamines due to factors like hearing loss and visual impairment.
Decongestants
- Oxymetazoline is classified as a nasal decongestant.
- Pseudoephedrine may cause cardiac dysrhythmias when taken with MAO inhibitors.
- Topical nasal decongestants should not be used for more than 3-5 days to prevent rebound congestion.
Patient Education
- Patients should avoid alcohol while on antihistamines and stay hydrated to combat dry mouth.
- Antitussives require patient education about avoiding respiratory irritants and proper usage of medications.
- Important to monitor effects of decongestants such as blood pressure and therapeutic outcomes.
Common Medications
- Fexofenadine is used for allergic rhinitis, but history of excessive alcohol use could be concerning.
- OTC combined cold medications often include oral decongestants among other ingredients.
- Phenylephrine and oxymetazoline reduce nasal swelling through vasoconstriction.
Monitoring and Assessment
- Patients taking decongestants should have ongoing assessments of blood pressure and congestion levels.
- Call a physician if symptoms don’t improve after seven days or if a high fever develops while using a decongestant.
