Adrenalin Side Effects Center

Pharmacy Editor: Melissa Conrad Stöppler, MD

Adrenalin (epinephrine) is a chemical that narrows blood vessels and opens airways in the lungs. These effects can reverse severe low blood pressure, wheezing, severe skin itching, hives, and other symptoms of an allergic reaction. An injection of adrenalin (epinephrine) is used to treat severe allergic reactions (anaphylaxis) to insect stings or bites, foods, drugs, and other allergens. Transient and minor side effects may occur and include anxiety, headache, fear, and palpitations.

Adrenalin is available in many different injectable forms including auto-injector systems that can be carried by those who are prone to serious allergic reactions. Adrenalin (epinephrine) has been shown to be teratogenic in rats when given in doses about 25 times the human dose. There are no adequate and well-controlled studies in pregnant women.

Our Adrenalin Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

(Adverse Reactions)

SIDE EFFECTS

Adverse Reactions Associated With Intramuscular/Subcutaneous Use (For Anaphylaxis)

Common adverse reactions to systemically administered epinephrine include anxiety, apprehensiveness, restlessness, tremor, weakness, dizziness, sweating, palpitations, pallor, nausea and vomiting, headache, and respiratory difficulties. These symptoms occur in some persons receiving therapeutic doses of epinephrine, but are more likely to occur in patients with heart disease, hypertension, or hyperthyroidism [see WARNINGS AND PRECAUTIONS].

Due to the lack of randomized, controlled clinical trials of epinephrine for the treatment of anaphylaxis, the true incidence of adverse reactions associated with the systemic use of epinephrine is difficult to determine. Adverse reactions reported in observational trials, case reports, and studies are listed below by body system:

Cardiovascular: angina, arrhythmias, hypertension, pallor, palpitations, tachyarrhythmia, tachycardia, vasoconstriction, and ventricular ectopy.

Angina may occur in patients with coronary artery disease [see WARNINGS AND PRECAUTIONS].

Arrhythmias, including fatal ventricular fibrillation, have occurred, particularly in patients with underlying organic heart disease or patients receiving drugs that sensitize the heart to arrhythmias [see WARNINGS AND PRECAUTIONS].

Rapid rises in blood pressure associated with epinephrine use have produced cerebral hemorrhage, particularly in elderly patients with cardiovascular disease [see WARNINGS AND PRECAUTIONS].

Respiratory: respiratory difficulties.

Neurological: dizziness , disorientation , excitability , headache , impaired memory , lightheadedness , nervousness , panic, psychomotor agitation, sleepiness , tingling , tremor, and weakness.

Psychiatric: anxiety, apprehensiveness, restlessness.

Gastrointestinal: nausea, vomiting.

Other: Patients with Parkinson's disease may experience psychomotor agitation or a temporary worsening of symptoms [see WARNINGS AND PRECAUTIONS].

Diabetic patients may experience transient increases in blood sugar [see WARNINGS AND PRECAUTIONS].

Accidental injection into the digits, hands or feet may result in loss of blood flow to the affected area [see WARNINGS AND PRECAUTIONS]. Adverse events experienced as a result of an injection into these areas include increased heart rate, local reactions including injection site pallor, coldness, hypoesthesia, and tissue loss, or injury at the injection site resulting in bruising, bleeding, discoloration, erythema, and skeletal injury.

Injection into the buttock has resulted in cases of gas gangrene [see WARNINGS AND PRECAUTIONS].

Skin: sweating.

Adverse Reactions Associated With Intraocular Use (For Mydriasis)

Epinephrine containing sodium bisulfite has been associated with corneal endothelial damage when used in the eye at undiluted concentrations (1 mg/mL).
