How does this medication work? What will it do for me?

Epinephrine belongs to a family of medications called sympathomimetics. These medications resemble chemicals that are normally found in our bodies and are released during stressful situations, such as when we are scared, anxious, or angry.

Epinephrine is used for the emergency treatment of severe allergic reactions (anaphylaxis) to insect bites, insect stings, food, medication, as well as other allergens (e.g., latex). During a severe allergic reaction, blood pressure can become dangerously low, breathing can become difficult, and the face and throat can swell. Other signs and symptoms can include hives, flushing, fast heart rate, paleness, weakness, dizziness, stomach cramps, nausea, vomiting, and diarrhea. Epinephrine works to reverse these effects.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are being given this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it.

What form(s) does this medication come in?

0.3 mg
Each single use prefilled auto-injector delivers a single dose of 0.3 mL that contains 0.3 mg of epinephrine (as epinephrine hydrogen tartrate). Nonmedicinal ingredients: disodium edetate, hydrochloric acid (to adjust pH), sodium chloride, sodium metabisulfite, and water for injection.

0.5 mg
Each single use prefilled auto-injector delivers a single dose of 0.5 mL that contains 0.5 mg of epinephrine (as epinephrine hydrogen tartrate). Nonmedicinal ingredients: disodium edetate, hydrochloric acid (to adjust pH), sodium chloride, sodium metabisulfite, and water for injection.

How should I use this medication?

The usual dose of epinephrine is based on your body weight, your risk of experiencing a serious allergic reaction, and your ability to tolerate the medication. The usual dose for children who weigh 15 kg to 30 kg is 0.15 mg. The usual dose for children and adults who weigh 30 kg to 60 kg is 0.3 mg. For adults and children who weigh more than 60 kg, the dose is 0.3 mg to 0.5 mg. For children who weigh less than 15 kg, other forms of injectable epinephrine may be prescribed.

The medication is injected into the thigh with use of a special automatic device that resembles a pen. To use the pen, first remove it from the carton. Remove the needle cap, then press the tip of the pen firmly against the outside muscle of the thigh, at a 90-degree angle, so the needle cover is depressed. When the device has been activated and the needle has penetrated the thigh, you will hear a click.  Hold the auto-injector against your thigh for 5 seconds. Remove the auto-injector from your thigh and lightly massage the injection site afterwards. The plunger will be visible after you have used the auto-injector, confirming that you have received the dose of epinephrine.

Seek immediate medical attention at the same time. If your symptoms have not improved or they have gotten worse, you can use a second dose 5 to 15 minutes later, if you have a second pen.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are using the medication without consulting your doctor.

It is important to use this medication exactly as prescribed by your doctor. It is also important to know how to use the autoinjector properly. If you are not sure, ask your doctor, nurse, or pharmacist for a demonstration.

Store this medication at room temperature, protect it from light, and keep it out of the reach of children. The pen should be stored in its original carton. Do not use it if the solution is darker than light yellow or has particles in it.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

Who should NOT take this medication?

Epinephrine should not be used by anyone who is allergic to epinephrine or to any of the ingredients of the medication.

The side effects listed below are not experienced by everyone who takes this medication. If you are concerned about side effects, discuss the risks and benefits of this medication with your doctor.

The following side effects have been reported by at least 1% of people taking this medication. Many of these side effects can be managed, and some may go away on their own over time.

Are there any other precautions or warnings for this medication?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Accidental injection: If epinephrine is accidentally injected into areas such as the hands or feet, go to the nearest emergency room for treatment. Epinephrine should only be injected into the thigh.

Asthma: People who have asthma may experience difficulty breathing after using epinephrine. If you have asthma, make sure you inform any emergency professionals that you have asthma and have used epinephrine. Discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Diabetes: People with diabetes may experience a temporary increase in blood glucose level after using epinephrine. If you have diabetes, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Be sure to tell any emergency professionals that you have diabetes and that you have used epinephrine.

Glaucoma: The symptoms of glaucoma can be made worse when epinephrine is used. If you have glaucoma, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Heart disease: Epinephrine has many effects throughout the body. It narrows the blood vessels, which in turn can increase blood pressure, heart rate and possibly cause irregular heartbeat. If you have heart disease, including high blood pressure, abnormal heartbeat or are taking medications that increase the risk of an irregular heartbeat (e.g., digoxin, amiodarone, sotalol, procainamide), or have an overactive thyroid, these conditions can be made worse for a short period of time, by using epinephrine. Discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication and whether any special monitoring is needed.

Be sure to tell any emergency professionals if you have any of these conditions and that you have used epinephrine.

Medical attention: Since the signs and symptoms of an allergic reaction may return after using this medication, it is important to get immediate medical attention after using it. You should be close to a hospital or emergency medical help for at least 24 hours after the start of your allergic reaction.

Skin infection: Severe skin infection has been known to occur after using epinephrine injections, although this is rare. If you experience ongoing redness, warmth, swelling, or tenderness at the injection site, seek immediate medical attention.

Parkinson’s disease (PD): People with PD may experience temporarily worsened symptoms of PD after using epinephrine.

Pregnancy: This medication should only be used during pregnancy if the benefits outweigh the risks.
