Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Be sure to describe the allergic reaction and its symptoms.
If you have taken certain medications for depression or Parkinson's disease within the last 14 days, including isocarboxazid, phenelzine, tranylcypromine, selegiline, or rasagiline, as this may increase the risk of very high blood pressure.
If you are currently taking linezolid or methylene blue, as these medications can interact with this drug.
If you are taking any other medications for nasal congestion, weight loss, or attention deficit hyperactivity disorder (ADHD), as these may interact with this medication.
This list is not exhaustive, and it is crucial to disclose all your medications, including prescription and over-the-counter drugs, natural products, and vitamins, as well as any health problems you may have. Your doctor and pharmacist need this information to ensure it is safe for you to take this medication with your other medications and health conditions. Never start, stop, or change the dose of any medication without first consulting your doctor.
Precautions & Cautions
This drug may cause high blood pressure or a rapid heartbeat, which can increase the risk of heart attack or stroke, potentially leading to fatal outcomes. If you have any concerns or questions, consult your doctor.
As directed, regularly monitor your blood pressure to ensure it remains within a safe range.
In some cases, women who received this medication in combination with other drugs like ergonovine and methylergonovine after childbirth have experienced severely high blood pressure, which has led to strokes in some individuals. If you have any questions or concerns, discuss them with your doctor.
If you are pregnant, planning to become pregnant, or are breastfeeding, notify your doctor. It is crucial to discuss the potential benefits and risks of this medication to both you and your baby to make an informed decision.
Overdose Information
Overdose Symptoms:
- Severe hypertension (very high blood pressure)
- Tachycardia (very fast heart rate)
- Cardiac arrhythmias (irregular heartbeats)
- Myocardial infarction (heart attack)
- Cerebral hemorrhage (bleeding in the brain)
- Seizures
- Coma
- Respiratory depression
- Hyperthermia
What to Do:
Immediate medical attention is required. Treatment is supportive and symptomatic. For severe hypertension, an alpha-adrenergic blocking agent (e.g., phentolamine) may be used. For arrhythmias, antiarrhythmics. For seizures, benzodiazepines. Call 1-800-222-1222 (Poison Control) or seek emergency medical care.
Drug Interactions
Contraindicated Interactions
- Monoamine Oxidase Inhibitors (MAOIs) - risk of hypertensive crisis
Major Interactions
- Tricyclic Antidepressants (TCAs) - potentiate pressor effect
- General Anesthetics (e.g., halogenated hydrocarbons like halothane, isoflurane) - increased risk of cardiac arrhythmias
- Other Sympathomimetics (e.g., pseudoephedrine, phenylephrine) - additive pressor effects
- Oxytocic Drugs (e.g., oxytocin, methylergonovine) - risk of severe persistent hypertension
- Alpha-adrenergic blocking agents (e.g., phentolamine) - may reduce pressor effect
- Beta-adrenergic blocking agents (e.g., propranolol) - may reduce pressor effect and cause unopposed alpha-stimulation
Moderate Interactions
- Cardiac Glycosides (e.g., digoxin) - increased risk of arrhythmias
- Diuretics (e.g., furosemide) - may reduce pressor response
- Ergot Alkaloids (e.g., ergotamine) - additive vasoconstriction
Minor Interactions
- Not many specific minor interactions documented for acute injectable use.
Monitoring
Baseline Monitoring
Rationale: To establish baseline and guide initial dosing.
Timing: Prior to administration
Rationale: To establish baseline and monitor for tachycardia/arrhythmias.
Timing: Prior to administration
Rationale: To assess cardiac rhythm and identify pre-existing abnormalities.
Timing: Prior to administration (especially in patients with cardiac history)
Rationale: To ensure adequate intravascular volume before vasopressor use.
Timing: Prior to administration
Routine Monitoring
Frequency: Continuously or every 1-2 minutes initially, then as clinically indicated
Target: Maintain systolic BP >90 mmHg or within patient's normal range
Action Threshold: Hypotension below target, or excessive hypertension
Frequency: Continuously
Target: Maintain within physiological limits, avoid excessive tachycardia
Action Threshold: Bradycardia, tachycardia, or new onset arrhythmias
Frequency: Continuous monitoring
Target: Normal sinus rhythm
Action Threshold: New onset arrhythmias (e.g., ventricular ectopy, tachycardia)
Frequency: Hourly (if catheterized)
Target: >0.5 mL/kg/hr
Action Threshold: Oliguria or anuria
Symptom Monitoring
- Chest pain
- Palpitations
- Headache
- Dizziness
- Anxiety
- Tremor
- Nausea/Vomiting
- Difficulty breathing
Special Patient Groups
Pregnancy
Pregnancy Category C. Use only if the potential benefit justifies the potential risk to the fetus. Ephedrine crosses the placenta and may cause fetal tachycardia and arrhythmias.
Trimester-Specific Risks:
Lactation
Ephedrine is excreted into breast milk. Caution is advised. Monitor breastfed infants for irritability, sleep disturbances, and feeding difficulties.
Pediatric Use
Use with caution. Dosing is weight-based. Children may be more sensitive to the pressor and CNS stimulant effects. Close monitoring of vital signs is essential.
Geriatric Use
Use with caution. Elderly patients may be more sensitive to the pressor effects and CNS stimulation of ephedrine. Start with lower doses and titrate slowly. Increased risk of adverse cardiovascular events due to age-related comorbidities.
Clinical Information
Clinical Pearls
- Ephedrine is commonly used to treat hypotension during spinal or epidural anesthesia due to its combined alpha and beta effects, which help maintain cardiac output and blood pressure.
- Tachyphylaxis (rapidly diminishing response to successive doses) can occur with repeated administration.
- Monitor patients closely for cardiac arrhythmias, especially those with pre-existing cardiac conditions.
- Caution is advised in patients with cardiovascular disease (e.g., hypertension, coronary artery disease, arrhythmias), hyperthyroidism, diabetes mellitus, prostatic hypertrophy, or narrow-angle glaucoma.
- Ensure adequate intravascular volume before administering ephedrine, as it is not a substitute for fluid resuscitation in hypovolemic patients.
Alternative Therapies
- Phenylephrine (pure alpha-agonist, often preferred for hypotension with high cardiac output)
- Norepinephrine (alpha and beta-1 agonist, potent vasopressor for shock)
- Dopamine (dose-dependent effects, often used for shock)
- Vasopressin (non-adrenergic vasopressor)
- Mephentermine (another indirect sympathomimetic)
Cost & Coverage
General Drug Facts
Store all medications in a secure location, out of the reach of children and pets, to prevent accidental ingestion. Properly dispose of unused or expired medications by checking with your pharmacist for guidance on the best disposal method. Unless instructed to do so, avoid flushing medications down the toilet or pouring them down the drain, as this can contaminate waterways. Many communities offer drug take-back programs, which your pharmacist can help you locate.
Some medications may come with an additional patient information leaflet, so it is a good idea to check with your pharmacist for more information. If you have any questions or concerns about your medication, consult with your doctor, nurse, pharmacist, or other healthcare provider.
In the event of a suspected overdose, immediately contact your local poison control center or seek emergency medical attention. Be prepared to provide critical information, including the name of the medication, the amount taken, and the time it was ingested, to ensure prompt and effective treatment.
