Serious side effects of Epinephrine topical

WARNING/CAUTION: Even though it may be rare, some people may have very bad and sometimes deadly side effects when taking a drug. Tell your doctor or get medical help right away if you have any of the following signs or symptoms that may be related to a very bad side effect:

  • Signs of an allergic reaction, like rash; hives; itching; red, swollen, blistered, or peeling skin with or without fever; wheezing; tightness in the chest or throat; trouble breathing, swallowing, or talking; unusual hoarseness; or swelling of the mouth, face, lips, tongue, or throat.

Other side effects of Epinephrine topical

All drugs may cause side effects. However, many people have no side effects or only have minor side effects. Call your doctor or get medical help if you have any side effects that bother you or do not go away.

These are not all of the side effects that may occur. If you have questions about side effects, call your doctor. Call your doctor for medical advice about side effects.

You may report side effects to the FDA at 1-800-332-1088. You may also report side effects at

For Healthcare Professionals

Applies to epinephrine topical: topical solution.


Cardiovascular side effects have included elevations in heart rate or blood pressure in up to 55% and arrhythmias in 3% to 17% (including fatal ventricular arrhythmias) when used to treat cardiac arrest. In smaller doses, epinephrine has caused peripheral coronary arterial vasodilation, but in larger doses, epinephrine has caused diffuse vasoconstriction. This has caused increased peripheral vascular resistance, which was important in patients with coronary artery disease (worsened myocardial ischemia/angina) or hypertension (risk of emergent hypertension/stroke). Dilated cardiomyopathy and acute left ventricular dysfunction have been associated with the use of epinephrine.[Ref]

Epinephrine can induce hypokalemia with resultant T wave changes on the electrocardiogram.

Rare cases of myocardial infarction have been associated with relatively small doses of epinephrine in patients at risk for coronary artery disease.

Rare cases of cardiomyopathy have been associated with brief and chronic exposure to epinephrine (including inhaled epinephrine). Animal studies have shown that catecholamines can cause an influx of calcium into myocardial cells, which may cause myocardial injury, particularly during periods of epinephrine-induced coronary vasoconstriction. Limited animal data suggest that calcium antagonists may protect against the cardiotoxic effects of catecholamines by preventing the generation of plasma borne cytotoxic compounds, which are probably free radicals.

Epinephrine may be more arrhythmogenic in some patients, such as patients with congenital long QT syndrome.[Ref]

Nervous system

Nervous system side effects have included fear, agitation, anxiety, tenseness, restlessness, headache, tremor, dizziness, lightheadedness, nervousness, sleeplessness, excitability, weakness, and increased parkinsonian tremors. Complications associated with epidural anesthesia with epinephrine have included nerve root ischemia and clinical paralysis/plegia..[Ref]


Respiratory side effects have rarely included pulmonary edema. In some cases, acute left ventricular dysfunction has been documented in the presence of epinephrine-induced pulmonary edema. In some patients, epinephrine has precipitated severe, prolonged asthmatic attacks.[Ref]


Hypersensitivity side effects have been extremely unusual. Contact dermatitis has been associated with ocularly applied epinephrine. These reactions have typically presented with lid edema and a thick yellow discharge.[Ref]


Local side effects have included local tissue ischemia after repeated injections. Chronic IM epinephrine injections have induced local vasoconstriction, predisposing patients to Clostridial infections.[Ref]


Metabolic side effects have included severe metabolic acidosis because of elevated blood concentrations of lactic acid after prolonged use of intravenous epinephrine. Catecholamines have induced glycogenolysis, elevated blood glucose and insulin concentrations, and hypokalemia. Rare cases of hyperglycemia and acidosis have been associated with high catecholamine states, such as anaphylaxis.[Ref]


Psychiatric side effects have included agitation, disorientation, impaired memory, aggressive or assaultive behavior, hallucinations, and psychosis.[Ref]


Mattana and Singhal reviewed 420 consecutive cases of cardiac arrest and found a 28.6% incidence of acute renal failure (ARF) among patients who survived for at least 24 hours after cardiac arrest. Patients in whom ARF developed received markedly higher doses of epinephrine during resuscitative efforts than patients without ARF. High doses of epinephrine were associated with a longer duration of cardiopulmonary resuscitation. The patients with ARF had a significantly decreased survival rate. It is possible that patients with severe cardiac disease were less resuscitatable, required more epinephrine, and were prone to develop ARF anyway. Other data have failed to associated ARF with the use of high dose epinephrine.[Ref]

Renal side effects have included new or worsened renal insufficiency in adult survivors of cardiac arrest, adults who underwent epinephrine-assisted venography, and in rare pediatric cases.[Ref]
