Overdose Information
Overdose Symptoms:
- Severe nervousness, restlessness, or anxiety
- Insomnia
- Tremor
- Seizures
- Hallucinations
- High blood pressure (hypertensive crisis)
- Tachycardia (fast heart rate)
- Arrhythmias
- Palpitations
- Nausea, vomiting
- Urinary retention
What to Do:
Seek immediate medical attention or call Poison Control (1-800-222-1222). Treatment is supportive and symptomatic. May involve gastric lavage, activated charcoal, and management of cardiovascular and CNS effects.
Drug Interactions
Contraindicated Interactions
- Monoamine Oxidase Inhibitors (MAOIs) (concurrent use or within 14 days of MAOI discontinuation) - risk of hypertensive crisis.
Major Interactions
- Other sympathomimetics (e.g., phenylephrine, ephedrine, amphetamines) - increased risk of cardiovascular effects (hypertension, tachycardia, arrhythmias).
- Tricyclic Antidepressants (TCAs) - may potentiate pressor effects of pseudoephedrine.
- Beta-blockers (non-selective, e.g., propranolol) - may increase risk of hypertension and bradycardia due to unopposed alpha-adrenergic activity.
- Digoxin - increased risk of arrhythmias.
Moderate Interactions
- Antihypertensives (e.g., guanethidine, methyldopa, reserpine, ACE inhibitors, ARBs, diuretics) - pseudoephedrine may reduce the antihypertensive effects.
- Ergot alkaloids (e.g., ergotamine, dihydroergotamine) - increased risk of vasoconstriction.
- CNS depressants (e.g., alcohol, sedatives, hypnotics) - additive CNS depression (though pseudoephedrine is a stimulant, some formulations may contain sedating antihistamines, or individual sensitivity may occur).
Minor Interactions
- Caffeine - additive stimulant effects.
Monitoring
Baseline Monitoring
Rationale: Pseudoephedrine can increase blood pressure, especially in individuals with pre-existing hypertension.

Special Patient Groups
Pregnancy
Pseudoephedrine is classified as Pregnancy Category C. While generally considered low risk for major malformations, some studies suggest a possible association with gastroschisis (a birth defect of the abdominal wall) when used in the first trimester, though data are conflicting. Use should be avoided in the first trimester if possible, and used with caution and only if clearly needed in later trimesters, under medical supervision.
Trimester-Specific Risks:
Lactation
Pseudoephedrine is excreted into breast milk in small amounts. It is generally considered compatible with breastfeeding (Lactation Risk L2). However, it may decrease milk supply, especially in mothers with established lactation or those who are sensitive to its effects. Monitor infant for irritability or sleep disturbances.
Pediatric Use
Extended-release pseudoephedrine is not recommended for children under 12 years of age due to potential for serious adverse effects and lack of established efficacy and safety in this age group for ER formulations. For younger children, liquid formulations with appropriate dosing are available, but generally, decongestants are not recommended for children under 2 years of age.
Geriatric Use
Use with caution in elderly patients due to increased sensitivity to sympathomimetic effects, particularly cardiovascular (hypertension, tachycardia) and central nervous system (insomnia, nervousness) adverse effects. Start with the lowest effective dose and monitor blood pressure and heart rate closely. Patients with pre-existing conditions like hypertension, glaucoma, or prostatic hypertrophy are at higher risk.
Clinical Information
Clinical Pearls
- Advise patients to avoid taking pseudoephedrine close to bedtime due to its stimulant effects and potential for insomnia.
- Counsel patients with pre-existing conditions such as hypertension, heart disease, hyperthyroidism, diabetes, or prostatic enlargement to consult their physician before using pseudoephedrine.
- Remind patients that pseudoephedrine is a stimulant and can cause nervousness, dizziness, or difficulty sleeping.
- Due to its potential for misuse in methamphetamine production, pseudoephedrine is often sold behind the pharmacy counter and subject to purchase limits (e.g., Combat Methamphetamine Epidemic Act of 2005).
Alternative Therapies
- Phenylephrine (oral decongestant, less effective than pseudoephedrine)
- Oxymetazoline (topical nasal decongestant spray, risk of rebound congestion with prolonged use)
- Saline nasal sprays or rinses (non-pharmacological, safe for all ages)
- Intranasal corticosteroids (e.g., fluticasone, mometasone - for allergic rhinitis, takes days to weeks for full effect)
- Antihistamines (for allergic rhinitis symptoms like sneezing, runny nose, itching)
