Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this medication, any of its components, or other substances, such as foods or drugs. Be sure to describe the allergic reaction you experienced, including any symptoms that occurred.
All medications you are currently taking, including prescription and over-the-counter (OTC) drugs, natural products, and vitamins. This is not an exhaustive list, and it is crucial to discuss all your medications and health conditions with your doctor.
* Any health problems you have, as they may interact with this medication.
To ensure your safety, do not start, stop, or change the dose of any medication without first consulting your doctor. It is your responsibility to verify that it is safe to take this medication with all your other medications and health conditions.

If you have a known allergy to sulfites, consult your doctor before taking this medication, as some products may contain sulfites.
Patients with high blood sugar (diabetes) should closely monitor their blood sugar levels while taking this drug.
Individuals 65 years or older should exercise caution when using this medication, as they may be more susceptible to side effects.
If you are pregnant, planning to become pregnant, or are breast-feeding, inform your doctor to discuss the potential benefits and risks of this medication to both you and your baby.
Overdose Information
Overdose Symptoms:
- Severe hypertension (high blood pressure)
- Tachycardia (rapid heart rate)
- Cardiac arrhythmias (irregular heartbeats)
- Palpitations
- Headache
- Tremor
- Anxiety
- Pulmonary edema (fluid in the lungs)
- Cerebral hemorrhage (bleeding in the brain)
What to Do:
Seek immediate medical attention. Call 911 or Poison Control (1-800-222-1222). Treatment is supportive, including alpha-blockers for severe hypertension and beta-blockers for arrhythmias, if appropriate.
Drug Interactions
Contraindicated Interactions
- No absolute contraindications in a life-threatening allergic reaction (anaphylaxis) where the potential benefits outweigh the risks.
Major Interactions
- Beta-adrenergic blockers (e.g., Propranolol): May antagonize the cardiac and bronchodilatory effects of epinephrine, leading to severe hypertension followed by bradycardia. May also increase risk of anaphylaxis.
- Alpha-adrenergic blockers (e.g., Phentolamine): May antagonize the pressor effects of epinephrine.
- Tricyclic antidepressants (TCAs) and Monoamine Oxidase Inhibitors (MAOIs): May potentiate the cardiovascular effects of epinephrine, leading to severe hypertension and arrhythmias.
- Cocaine, Amphetamines, other sympathomimetics: Additive cardiovascular effects, increased risk of arrhythmias and hypertension.
Moderate Interactions
- Cardiac glycosides (e.g., Digoxin): Increased risk of cardiac arrhythmias.
- Diuretics (e.g., Loop diuretics, Thiazide diuretics): May reduce arterial responsiveness to pressor agents like epinephrine.
- Antihistamines (e.g., Diphenhydramine, Chlorpheniramine): May potentiate the effects of epinephrine (less common, but possible with older antihistamines).
Minor Interactions
- Not typically classified for emergency use.
Monitoring
Baseline Monitoring
Rationale: Epinephrine auto-injector is for immediate, life-threatening allergic reactions.
Timing: Prior to administration
Routine Monitoring
Frequency: Continuously after administration
Target: Improvement or resolution
Action Threshold: If symptoms persist or recur, administer a second dose and seek immediate medical attention.
Frequency: Continuously after administration until medical help arrives
Target: Stabilization towards normal
Action Threshold: Significant deviations or worsening indicate need for further medical intervention.
Symptom Monitoring
- Difficulty breathing (wheezing, shortness of breath)
- Swelling of face, lips, tongue, or throat
- Hives or rash
- Dizziness or fainting
- Rapid or weak pulse
- Nausea, vomiting, diarrhea
- Feeling of impending doom
Special Patient Groups
Pregnancy
Epinephrine should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. In a life-threatening situation like anaphylaxis, the benefits of treating the mother outweigh the potential risks to the fetus.
Trimester-Specific Risks:
Lactation
Epinephrine is rapidly metabolized and has a very short half-life. It is considered compatible with breastfeeding, and adverse effects on the infant are unlikely.
Pediatric Use
Dosing is weight-based. The 0.15 mg auto-injector is specifically designed for pediatric patients weighing 15-30 kg (33-66 lbs). For children weighing less than 15 kg, a lower dose (e.g., 0.01 mg/kg) administered via syringe may be necessary. For children over 30 kg, the 0.3 mg auto-injector is typically used.
Geriatric Use
Use with caution in elderly patients due to increased sensitivity to the pressor and cardiac effects of epinephrine. Pre-existing cardiovascular disease (e.g., coronary artery disease, hypertension) may increase the risk of adverse effects such as angina, myocardial infarction, or arrhythmias. Monitor closely.
Clinical Information
Clinical Pearls
- Epinephrine is the first-line treatment for anaphylaxis and should be administered immediately upon recognition of a severe allergic reaction.
- Always carry two auto-injectors, as a second dose may be needed if symptoms persist or recur.
- Administer into the anterolateral aspect of the thigh, through clothing if necessary. Do not inject into a vein, buttocks, fingers, or toes.
- After administering epinephrine, always seek immediate medical attention, even if symptoms improve, as biphasic reactions can occur.
- Proper training on how to use the auto-injector is crucial for patients and caregivers.
Alternative Therapies
- While other medications (e.g., antihistamines, corticosteroids, bronchodilators) may be used as adjunctive therapy for anaphylaxis, none are a substitute for epinephrine as the primary, life-saving treatment for acute anaphylaxis.
