5.7 Decongestants
Open Resources for Nursing (Open RN)
Pseudoephedrine is an over-the-counter (OTC) decongestant (see Figure 5.9[1]). More details regarding pseudoephedrine are described in the “Autonomic Nervous System” chapter.
Mechanism of Action
Pseudoephedrine acts directly on the adrenergic receptors and acts indirectly by releasing norepinephrine from its storage sites. The drug produces vasoconstriction, which shrinks nasal mucosa membranes.
Indications for Use
Decongestants relieve nasal obstruction due to inflammation.
Nursing Considerations Across the Lifespan
This medication is not safe for children under the age of 4 years.
Adverse/Side Effects
Common adverse/side effects include hypertension, dysrhythmia, dizziness, headache, insomnia, and restlessness. Some patients may experience blurred vision, tinnitus, chest tightness, dry nose, and nasal congestion.
Decongestants are contraindicated in patients with severe hypertension, coronary artery disease (CAD), narrow-angle glaucoma, and some antidepressant use. Also, use with caution in patients who have cardiac dysrhythmias, hyperthyroidism, DM (diabetes mellitus), prostatic hypertrophy, and glaucoma.[2]
Patient Teaching & Education
Patients must take care to follow dosing recommendations. If dosing standards are surpassed, some patients may experience side effects such as increased nervousness, breathing difficulties, heart rate changes, and hallucinations.[3]
Now let’s take a closer look at the medication grid on Pseudoephedrine in Table 5.7.[4], [5], [6]
