Adrenaclick (epinephrine) Auto-injector is a sympathomimetic catecholamine used in the emergency treatment of severe allergic reactions (Type I) including anaphylaxis to stinging or biting insects, allergen immunotherapy, foods, drugs, diagnostic testing substances, and other allergens, as well as anaphylaxis to unknown substances, or exercise-induced anaphylaxis. Adrenaclick is intended for immediate administration in patients with a history of anaphylactic reactions. Common side effects of Adrenaclick include:
- feeling over-excited
- rapid heartbeat (palpitations)
- irregular heartbeat
- pale skin (pallor)
- nausea and vomiting
- headache, or
- breathing difficulties
Adrenaclick is capable of delivering one dose of either 0.15 mg or 0.3 mg (0.15 mL or 0.3 mL) of epinephrine. This dose is available for auto-injection by the patient. Selection of the appropriate Adrenaclick dosage strength is determined according to patient body weight. Adrenaclick may interact with cardiac glycosides, diuretics, antidepressants, monoamine oxidase inhibitors, sodium levothyroxine, antihistamines, beta-blockers, alpha-blockers, ergot alkaloids, and phenothiazines. Tell your doctor all medications and supplements you use. During pregnancy, Adrenaclick should be used only if prescribed. Consult your doctor before breastfeeding.

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.
Common adverse reactions to systemically administered epinephrine include anxiety; apprehensiveness; restlessness; tremor; weakness; dizziness; sweating; palpitations; pallor; nausea and vomiting; headache, and/or respiratory difficulties. These symptoms occur in some persons receiving therapeutic doses of epinephrine, but are more likely to occur in patients with hypertension or hyperthyroidism [see WARNINGS AND PRECAUTIONS].
Arrhythmias, including fatal ventricular fibrillation, have been reported, particularly in patients with underlying cardiac disease or those receiving certain drugs [see WARNINGS AND PRECAUTIONS and DRUG INTERACTIONS].
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 accidental injections may include increased heart rate, local reactions including injection site pallor, coldness and hypoesthesia or injury at the injection site resulting in bruising, bleeding, discoloration, erythema or skeletal injury.
Lacerations, bent needles, and embedded needles have been reported when Adrenaclick has been injected into the thigh of young children who are uncooperative and kick or move during an injection [see WARNINGS AND PRECAUTIONS].
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].
