Adrenaline (base) 300micrograms/3ml (1 in 10,000) dilute solution for injection pre-filled syringes
Epinephrine, also known as <em>adrenaline</em>, is a hormone and neurotransmitter and produced by the adrenal glands that can also be used as a drug due to its various important functions.
Safety information for pregnancy and breastfeeding
Pregnancy
Pregnancy
Epinephrine is teratogenic in rats when given in doses about 25 times the human doses.
Parenteral administration of epinephrine, if used as support for blood pressure during low or other spinal anesthesia for delivery, can lead to the acceleration of fetal heart rate and should not be used in obstetrics when maternal blood pressure is higher than 130/80.
Always consult your doctor or midwife before taking any medicine during pregnancy or while breastfeeding. Source: DrugBank (CC BY-NC 4.0).

In general, the most common uses of parenteral epinephrine are to relieve respiratory distress due to bronchospasm, to provide rapid relief of hypersensitivity (anaphylactic or anaphylactoid) reactions to drugs, animal serums and other allergens, and to prolong the action of infiltration anesthetics F2136. In addition to the above functions, epinephrine is the primary drug administered during cardiopulmonary resuscitation (CPR) to reverse cardiac arrest [A37697], [A37699]. It can be used in severe cases of croup [L4824].
[L41260][L51798]
Epinephrine injection is also used to increase mean arterial blood pressure in adult patients with hypotension associated with septic shock.
[L41260]
Epinephrine's cardiac effects may be of use in restoring cardiac rhythm in cardiac arrest due to various causes but is not used in cardiac failure or in hemorrhagic, traumatic, or cardiogenic shock F1247.
Epinephrine is used as a hemostatic agent. It is so used in treating mucosal congestion of hay fever, rhinitis, and acute sinusitis; to relieve bronchial asthmatic paroxysms; in syncope due to complete heart block or carotid sinus hypersensitivity; for symptomatic relief of serum sickness, urticaria, angioneurotic edema; for resuscitation in cardiac arrest following anesthetic accidents; in simple (open-angle) glaucoma; for relaxation of uterine musculature and to inhibit uterine contractions. Epinephrine injection can be utilized to prolong the action of local anesthetics F1247.
In addition to the above, epinephrine is used as an over the counter (OTC) agent for the intermittent symptoms of asthma, such as wheezing, tightness of chest and shortness of breath F2131. It is also used for the maintenance of mydriasis during intraocular surgery .

Pregnancy
Epinephrine is teratogenic in rats when given in doses about 25 times the human doses. It is unknown whether epinephrine can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Epinephrine should be given to a pregnant woman only if clearly required in critical situations/emergencies F2136.
Labor and Delivery
Parenteral administration of epinephrine, if used as support for blood pressure during low or other spinal anesthesia for delivery, can lead to the acceleration of fetal heart rate and should not be used in obstetrics when maternal blood pressure is higher than 130/80.
Epinephrine may delay the second stage of labour.
Common and generalized adverse effects:
Transient and minor side effects of anxiety, headache, fear, and palpitations may occur with therapeutic doses of epinephrine, especially in hyperthyroid individuals. Repeated local injections may result in necrosis at sites of injection due to vascular constriction. Cerebral hemorrhage; hemiplegia; subarachnoid hemorrhage; anginal pain in patients with angina pectoris; anxiety; restlessness; throbbing headache; tremor; weakness; dizziness; pallor; respiratory difficulty; palpitation; apprehensiveness; sweating; nausea; vomiting [FDA label].
Cardiovascular effects: Inadvertently induced high arterial blood pressure may result in angina pectoris (especially when coronary insufficiency is present), cardiac ischemia, or aortic rupture [FDA label], .
[L4825]
Epinephrine may cause serious cardiac arrhythmias in patients not suffering from heart disease and patients with organic heart disease receiving drugs that sensitize the cardiac muscle.
With the injection of epinephrine 1:1,000, a paradoxical but transient lowering of blood pressure, bradycardia and apnea may occur immediately post-injection [FDA label].
Cerebrovascular hemorrhage: Overdosage or accidental I.V. injection of epinephrine may lead to cerebrovascular hemorrhage resulting from the sharp rise in blood pressure [FDA label].
Renal vasoconstriction: Parenterally administered epinephrine initially may produce constriction of renal blood vessels and decrease urine formation. High doses may cause complete renal shutdown F2136.
Pulmonary edema: Fatality may also result from pulmonary edema due to the peripheral constriction and cardiac stimulation produced by epinephrine injection [FDA label].
Digital vasoconstriction: Since epinephrine is a strong vasoconstrictor, accidental injection into the digits, hands or feet may lead to the loss of blood flow to the affected area. Treatment should be directed at vasodilation in addition to further treatment of anaphylaxis [FDA label].
Important effects of epinephrine include increased heart rate, myocardial contractility, and renin release via beta-1 receptors. Beta-2 effects produce bronchodilation which may be useful as an adjunct treatment of asthma exacerbations as well as vasodilation, tocolysis, and increased aqueous humor production [L4825]. In croup, nebulized epinephrine is associated with both clinically and statistically significant transient reduction of croup symptoms 30 minutes post-treatment [A40032]. Epinephrine also alleviates pruritus, urticaria, and angioedema and may be helpful in relieving gastrointestinal and genitourinary symptoms associated with anaphylaxis because of its relaxing effects on the smooth muscle of the stomach, intestine, uterus, and urinary bladder [FDA label].
How the body processes this drug — absorption, distribution, metabolism, and elimination
The drug becomes fixed in the tissues rapidly F1247, [FDA label].
[L4361]
[L4361]
About 40% of a parenteral dose of epinephrine is excreted in urine as metanephrine, 40% as VMA, 7% as 3-methoxy-4-hydroxyphenoglycol, 2% as 3,4-dihydroxymandelic acid, and the rest as acetylated derivatives. These metabolites are excreted mainly as the sulfate conjugates and, to a lesser extent, the glucuronide conjugates. Only small amounts of the drug are excreted completely unchanged .
