What are the basic uses of epinephrine?

Answer 1

The epi-pen was created to delay anaphylactic shock among people with severe Allergies. Symptoms of anaphylactic shock, also known as anaphylaxis, include the severe constriction of blood vessels and bronchial tubes due to an extreme allergic reaction. Most cases of anaphylaxis are fatal if not treated before total constriction of bronchial tubes (usually within 10-20min). Immediate hospitalization is required to bring histamine levels back to normal.

The epi-pen is designed to create immediate production of the hormone adrenaline which prevents the blood vessels and bronchial tubes from completely constricting. Allowing the victim time to get to the hospital.

As soon as the person with the allergies start complaining of throat closure or they come in contact with a known life-threatening allergen, The epi-pen should be injected into the person's thigh! It is essential to inject the epi-pen as quickly as possible, before anaphylaxis can set in. Quick recognition and injection can save lives.

Note: Anaphylaxis results in vasodilatation (the opposite of constriction) which leads to a drop in blood pressure since there is not enough blood volume in the body to fill all the blood vessels to capacity if they are all dilated and still maintain a blood pressure. This is why people in anaphylactic shock often have pink, well-perfused skin rather then the usual pallor associated with shock of other causes. An Epi-pen contains adrenaline (which is another name for epinephrine) which can reverse bronchconstriction and vasodilatation directly and not through the facilitation of epinephrine production. As noted above, the epi pen should be administered as soon as the condition is suspected because the combination of shock and inadequate ventilation of the lungs can be rapidly fatal and becomes more difficult to reverse as time goes on. The design of the epi-pen is such that it can be administered by the victim themselves if they are conscious enough and no help is available, and should be in conjunction with a call for EMS in case further intervention becomes necessary.

Answer 2

An epi pen delivers an emergency dose of epinephrine to counteract anaphylaxis (severe allergic reactions).

Anaphylaxis causes your airway to close up and your veins to dilate, causing difficulty breathing and a severe drop in blood pressure. Epinephrine has bronchodilatory effects which open the airway, and causes your blood vessels to constrict, which then increase your blood pressure.

When you have been stung by an insect or are having a severe allergic reaction and you are having difficulty breathing.

Please consult your physician or pharmacist for instructions on how and when to use an Epipen.
