Monitoring
Baseline Monitoring
Rationale: Pseudoephedrine can increase blood pressure, especially in patients with pre-existing hypertension.
Timing: Before initiation, particularly in patients with cardiovascular risk factors.
Rationale: Pseudoephedrine can cause tachycardia or palpitations.
Timing: Before initiation, particularly in patients with cardiovascular risk factors.
Routine Monitoring
Frequency: Daily, as needed
Target: Improved breathing, reduced congestion
Action Threshold: Lack of improvement or worsening symptoms may indicate need for alternative therapy or medical evaluation.
Frequency: Periodically, especially in patients with hypertension or cardiovascular disease
Target: Within patient's normal or target range
Action Threshold: Significant increase (e.g., >20 mmHg systolic or >10 mmHg diastolic) or development of hypertensive symptoms.
Frequency: Periodically, especially in patients with cardiovascular disease
Target: Within patient's normal range
Action Threshold: Persistent tachycardia, palpitations, or arrhythmias.
Symptom Monitoring
- Nasal congestion relief
- Headache
- Dizziness
- Nervousness
- Insomnia

Special Patient Groups
Pregnancy
Pseudoephedrine is Pregnancy Category C. It should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Some studies suggest a possible association with gastroschisis when used in the first trimester, though data are conflicting. Generally, it is best to avoid decongestants in the first trimester.
Trimester-Specific Risks:
Lactation
Pseudoephedrine is excreted into breast milk. While generally considered compatible with breastfeeding (L2), infants should be monitored for irritability, sleep disturbances, or decreased milk supply in the mother.
Pediatric Use
Not recommended for children under 2 years of age due to potential for serious adverse effects. Use age-appropriate dosing for older children. Overdose can be particularly dangerous in this population.
Geriatric Use
Elderly patients may be more sensitive to the effects of pseudoephedrine, particularly cardiovascular (hypertension, tachycardia) and central nervous system (insomnia, nervousness) effects. Use with caution and consider lower starting doses.
Clinical Information
Clinical Pearls
- Pseudoephedrine is a precursor chemical for methamphetamine production, leading to restrictions on its sale (e.g., behind-the-counter sales, purchase limits).
- Patients with hypertension, heart disease, thyroid disease, diabetes, or prostatic hypertrophy should use pseudoephedrine with caution and under medical supervision.
- Advise patients to avoid taking pseudoephedrine close to bedtime due to its stimulant effects which can cause insomnia.
- Extended-release formulations are available for longer duration of action, but the 30mg tablet is typically immediate-release.
- Educate patients on the difference between pseudoephedrine and phenylephrine, as phenylephrine is often less effective as an oral decongestant.
Alternative Therapies
- Topical nasal decongestants (e.g., oxymetazoline, phenylephrine nasal spray - for short-term use only to avoid rebound congestion)
- Oral phenylephrine (less effective than pseudoephedrine)
- Saline nasal sprays/washes
- Antihistamines (for allergy-related congestion, e.g., loratadine, cetirizine, fexofenadine)
- Intranasal corticosteroids (for allergic rhinitis, e.g., fluticasone, budesonide)
