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 is used to treat severe allergic reactions (anaphylaxis) to insect stings or bites, foods, drugs, and other allergens. Side effects of Adrenalin include:

Before using Adrenalin a second time, tell your doctor if your first injection caused serious side effects such as increased breathing difficulty, or dangerously high blood pressure (severe headache, blurred vision, buzzing in your ears, anxiety, confusion, chest pain, shortness of breath, uneven heartbeats, seizure).

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. The dose for adults and children 30 kg (66 lbs) or more is 0.3 to 0.5 mg (0.3 mL to 0.5 mL) of undiluted Adrenalin administered intramuscularly or subcutaneously in the anterolateral aspect of the thigh, up to a maximum of 0.5 mg (0.5 mL) per injection, repeated every 5 to 10 minutes as necessary. Adrenalin may interact with digoxin, diuretics (water pills), levothyroxine, chlorpheniramine or diphenhydramine (antihistamines commonly contained in cold, allergy, or over-the-counter sleep medications), antidepressants, beta-blockers, ergot medicines, heart rhythm medications, or MAO inhibitors. Tell your doctor all medications and supplements you use. There are no adequate and well-controlled studies in pregnant women. Tell your doctor if you are pregnant before using Adrenalin. Consult your doctor before breastfeeding.

SIDE EFFECTS

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].

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

Neurological: disorientation, impaired memory, panic, psychomotor agitation, sleepiness, tingling.

Psychiatric: anxiety, apprehensiveness, restlessness.

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.

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

Rare cases of serious skin and soft tissue infections, including necrotizing fasciitis and myonecrosis caused by Clostridia (gas gangrene), have been reported following epinephrine injection in the thigh [see WARNINGS AND PRECAUTIONS].
