Overdose Information
Overdose Symptoms:
- Severe nervousness, restlessness, or anxiety
- Insomnia
- Dizziness or lightheadedness
- Tremors or seizures
- Hallucinations
- Rapid or irregular heartbeat (tachycardia, arrhythmias)
- High blood pressure (hypertensive crisis)
- Nausea, vomiting
- Difficulty breathing
- Urinary retention
What to Do:
Seek immediate medical attention or call Poison Control (1-800-222-1222). Management is supportive, including gastric lavage, activated charcoal, and symptomatic treatment for cardiovascular and CNS effects.
Drug Interactions
Contraindicated Interactions
- Monoamine Oxidase Inhibitors (MAOIs) (e.g., phenelzine, selegiline, tranylcypromine, linezolid, methylene blue) - concurrent use or within 14 days of MAOI discontinuation due to risk of hypertensive crisis.
Major Interactions
- Other sympathomimetics (e.g., decongestants, appetite suppressants, amphetamines) - increased risk of cardiovascular and CNS adverse effects.
- Beta-blockers (non-selective) - may reduce antihypertensive effect and increase risk of hypertension and bradycardia.
- Tricyclic Antidepressants (TCAs) (e.g., amitriptyline, imipramine) - may potentiate pressor effects of pseudoephedrine.
- Ergot alkaloids (e.g., ergotamine, dihydroergotamine) - increased risk of vasoconstriction and hypertension.
Moderate Interactions
- Antihypertensives (e.g., methyldopa, reserpine, guanethidine) - pseudoephedrine may reduce their antihypertensive effects.
- Cardiac glycosides (e.g., digoxin) - increased risk of arrhythmias.
- Thyroid hormones - increased risk of cardiovascular effects.
- Caffeine and other CNS stimulants - increased risk of nervousness, irritability, insomnia.
Minor Interactions
- Antacids - may increase pseudoephedrine absorption.
- Kaolin - may decrease pseudoephedrine absorption.
Monitoring
Baseline Monitoring
Rationale: Pseudoephedrine can increase BP and HR, especially in patients with pre-existing cardiovascular conditions.
Timing: Prior to initiation, especially in patients with hypertension or cardiac disease.
Rationale: Pseudoephedrine is contraindicated or requires caution in these conditions.
Timing: Prior to initiation.
Routine Monitoring
Frequency: Daily
Target: Reduction in symptoms
Action Threshold: If symptoms worsen or persist beyond 7 days, discontinue and seek medical advice.
Frequency: Periodically, especially in patients with pre-existing cardiovascular conditions or those reporting palpitations/dizziness.
Target: Within patient's normal range
Action Threshold: Significant increase in BP/HR, or new onset of palpitations/arrhythmias, discontinue and seek medical advice.
Frequency: Daily
Target: Absence or mild, tolerable
Action Threshold: Severe or persistent CNS effects, discontinue and seek medical advice.
Symptom Monitoring
- Nasal congestion
- Cough frequency and productivity
- Sputum thickness and color
- Insomnia
- Nervousness or restlessness
- Dizziness
- Headache
- Palpitations or rapid heart rate
- Increased blood pressure
- Tremor
- Difficulty urinating (especially in men with prostate enlargement)
Special Patient Groups
Pregnancy
Category C. Use only if the potential benefit justifies the potential risk to the fetus. Pseudoephedrine has been associated with a small increased risk of gastroschisis in some studies, particularly in the first trimester. Guaifenesin is generally considered low risk but data are limited.
Trimester-Specific Risks:
Lactation
L3 (Moderately Safe). Both guaifenesin and pseudoephedrine are excreted into breast milk. Pseudoephedrine can reduce milk supply, especially in early lactation. Monitor infant for irritability, sleep disturbances, or other adverse effects.
Pediatric Use
Not recommended for children under 4 years of age due to potential for serious side effects and lack of proven efficacy. For children 4-12 years, use only under medical supervision and with age-appropriate dosing. Adolescents âĨ12 years can follow adult dosing. Always use pediatric formulations or consult a healthcare professional for appropriate dosing.
Geriatric Use
Use with caution. Elderly patients may be more sensitive to the cardiovascular and CNS effects of pseudoephedrine (e.g., hypertension, tachycardia, insomnia, nervousness, urinary retention). Start with the lowest effective dose and monitor closely for adverse effects. Consider pre-existing conditions like hypertension, glaucoma, or prostate enlargement.
Clinical Information
Clinical Pearls
- Advise patients to stay well-hydrated to maximize the expectorant effect of guaifenesin.
- Caution patients about potential CNS stimulation (insomnia, nervousness) from pseudoephedrine, especially if taken close to bedtime.
- Remind patients that pseudoephedrine is often kept behind the pharmacy counter due to regulations on its sale (Combat Methamphetamine Epidemic Act of 2005).
- Educate patients to check other cold/flu medications for similar active ingredients to avoid accidental overdose.
- This combination is for symptomatic relief and does not treat the underlying cause of the cold or flu.
Alternative Therapies
- Single-ingredient Guaifenesin (e.g., Mucinex)
- Single-ingredient Pseudoephedrine (e.g., Sudafed)
- Nasal saline sprays (for congestion)
- Humidifiers (for congestion and cough)
- Cough suppressants (e.g., dextromethorphan, codeine - if cough is non-productive and bothersome)
- Antihistamines (for allergy-related symptoms)
