Frequently asked questions

When should I inject EpiPen®?

EpiPen® should be injected at the first sign or symptom of a severe allergic response. Severe allergic reactions are not always predictable. Obvious warning signs are not always present before serious reactions occur.

EpiPen® is recommended at the start of any reaction to a known or suspected allergen contact. For people with a history of a severe cardiovascular collapse on exposure to an allergen, the physician may advise that epinephrine be administered immediately after exposure to that allergen, before any reaction has begun.

EpiPen®, when used as directed immediately following exposure to a known allergen, may prove life-saving.

How do I administer EpiPen®?

EpiPen® is administered in a simple 2-step process:

Person pulling blue cap off of EpiPen device, “Blue to the sky”

Grasp with orange tip pointing downward

Remove blue safety cap by pulling straight up – do not bend or twist

Person injecting orange side of EpiPen device into thigh, “Orange to the thigh”

Place the orange tip against the middle of the outer thigh

Swing and push the auto-injector firmly into the thigh until it “clicks”

Hold firmly in place for 3 seconds – count slowly, “1, 2, 3”

What should I do after using EpiPen®?

Call 911 after using EpiPen®.

Using EpiPen® does not replace seeing a doctor or going to the hospital.

Seek medical attention immediately.

The effects of epinephrine can wear off or you could have a second reaction, so call 911, or go to the emergency room right after using EpiPen.

When the dose is delivered and EpiPen® is released from the injection site, the orange needle cover will automatically extend and immediately locks in place.

Give any used EpiPen® Auto-Injectors to emergency responders or emergency room personnel to discard.

These instructions are found on the barrel of EpiPen® as well as in the prescribing information.

Why should I swing my arm to inject?

It is recommended that you swing your arm to inject EpiPen®. You do not need to apply excessive force to the swing, just enough to gain sufficient momentum to ensure the auto-injector deploys. Swinging your arm helps provide enough load on the tip of the EpiPen® to deliver an intramuscular (IM) injection. Administering EpiPen® in this manner also helps facilitate the ideal angle for the IM injection into the anterolateral aspect of the thigh, which is perpendicular or at 90 degrees to the injection site.

How many seconds should I hold EpiPen® in place when I inject?

The instructions on the EpiPen® cartridge state you should swing the arm and push the orange tip firmly into the mid-outer thigh so it ‘clicks’ and hold it firmly on the thigh for 3 seconds (count slowly “1, 2, 3”). Holding EpiPen® firmly in place at the injection site for 3 seconds helps to properly deliver the dose of epinephrine.

How do I know if EpiPen® has been activated?

The extended orange needle cover and obscured window indicates that EpiPen® has delivered the drug.

How do I know if I have received my injection?

There is a viewing window on the barrel of EpiPen® which prior to delivery is clear and after delivery is obscured or shaded. Also, once the dose is administered and EpiPen® is released from the injection site, the orange needle cover extends and immediately locks in place encasing the needle to prevent accidental needle sticks. These visual indicators show that the dose of epinephrine has been delivered. Once the orange needle cover is extended, EpiPen® will not fit back into the carrier tube.

Can I inject EpiPen® through my clothes?

Yes. If necessary, you can inject EpiPen® through clothing.

What do I do in the event of an accidental injection into hands or feet, etc.?

Accidental injection into the hands or feet may result in loss of blood flow to the affected areas and should be avoided. If there is an accidental injection into these areas, go immediately to the nearest emergency room for treatment.

How should I dispose of a used EpiPen®?

After using EpiPen®, seek medical attention. The used EpiPen® should be taken to the nearest Emergency Room for proper disposal and to show the medical personnel what medication has already been administered.

For an expired EpiPen®, contact your local pharmacy to assist in disposal of the product according to regulations.

What should I do if I accidentally remove the blue safety cap release from EpiPen®?

If the unit has not been activated, then the blue safety cap can be carefully replaced. Because removing the blue safety cap prepares the unit for activation, you should gently place the unit in its needle-safe storage tube. Make sure the safety release end faces towards the opening and secure the blue safety cap in place. Be very careful to keep your fingers clear of each end.

Does EpiPen® come with needle protection?

EpiPen® has a built-in needle protection device (orange needle cover). This device automatically extends when the dose is administered and the EpiPen® Auto-Injector is removed from the injection site.

The extended needle protection sheath will prevent the EpiPen® Auto-Injector from fitting back into the carrier tube.

Do you have to be certified to administer EpiPen® to someone else who is in need of the medication but unable to administer it themselves?

Emergency administration of EpiPen® in the case of a suspected severe allergic reaction does not require certification. The patient’s physician or pharmacist should review the package insert in detail with the patient or caregiver to ensure that he/she understands the indications and use of EpiPen®.

Actual demonstration of the injection technique by a physician or pharmacist is recommended.

It is important that people at risk of a severe allergic reaction educate others on how to use EpiPen®.

EpiPen® and EpiPen Jr® are designed as emergency supportive therapy only and not as a replacement or substitute for subsequent medical or hospital care. After administration, patients should seek medical attention immediately or go to the emergency room. For the next 48 hours, patients must stay within close proximity to a healthcare facility or where they can call 911.

What are the dosing guidelines for EpiPen®?

EpiPen® dosage should be based on body weight.

EpiPen auto-injector

EpiPen®: Unidose 0.3 mg epinephrine auto-injector

EpiPen® (0.3 mg) should be used for adults and children weighing 30 kg or more.

EpiPen junior auto-injector

EpiPen Jr®: Unidose 0.15 mg epinephrine auto-injector

EpiPen Jr® should be used for children weighing between 15 kg to 30 kg.

For children weighing less than 15 kg, call 911.

Dosage adjustments are at the discretion of a healthcare provider.

How many doses of EpiPen® can be administered?

If you or your child do not feel better or get worse, you can inject another dose of EpiPen® or EpiPen Jr® 5 to 15 minutes after the first injection.

Do not inject more than 2 injections right after each other.

Too much epinephrine can cause dangerously high blood pressure, stroke, or death. Signs of an overdose include:

  • Irregular heart beat
  • Difficulty breathing caused by a build-up of fluid in your lungs

You must seek medical assistance or go to a hospital emergency room immediately after using EpiPen® or EpiPen Jr®.

Even if you have sought medical help, you must stay within close proximity to a hospital or where you can easily call 911 for the next 48 hours.

A severe allergic reaction is a serious, acute, allergic reaction that may cause death. It has a sudden onset and generally lasts less than 24 hours. Because a severe allergic reaction is a generalized reaction, a wide variety of clinical signs and symptoms may be observed.

Physicians may determine that a single dose of epinephrine may not be enough to reverse the symptoms of a severe allergic reaction. As such, your healthcare provider may prescribe more than one EpiPen® to have on hand.

What length of expiry should I expect when purchasing EpiPen®?

Each new EpiPen® should have a minimum of 12 months before expiry. If you have recently bought an EpiPen® or EpiPen Jr® Auto-Injector that has a shorter expiry date, please talk to your pharmacist.

How do I read the expiry date on EpiPen®?

The expiration date is expressed as the month and the last 2 digits of the year. For example, an expiration designation of “Exp: JA 19” indicates that the EpiPen® expires the last day (31st) of January 2019, thus the expiration date in this example would be January 31, 2019.

Further, expiration dates on EpiPen® (Canada) are different than product from the U.S. The Canadian product is designed to be "bilingual friendly", e.g. JA = Jan, JN = June, JL = July, MA = May, MR = March.

If the EpiPen® is expired, can it still be used?
How do I store EpiPen® and under what conditions should I consider the auto-injector compromised?

It’s important to properly store EpiPen® to help ensure it’s ready to use in the event of a severe allergic reaction.

When storing EpiPen® or EpiPen Jr®, follow these recommendations:
  • Store at room temperature. Never store in a refrigerator or freezer.
  • Do not drop.
  • Do not expose to direct sunlight.
  • Do not keep EpiPen® in a vehicle during extremely hot or cold weather.
  • Always keep your EpiPen® or EpiPen Jr® in the carrier tube to protect it from damage. However keep in mind that the carrier tube is not waterproof.
  • The blue safety release cap helps to prevent accidental injection. Keep the blue safety release cap on until you need to use it.
  • Do not keep folded paper instructions or any other objects in the carrier tube with your EpiPen® Auto-Injector. This may prevent removing the auto-injector quickly in the event of a severe allergic emergency.
  • Keep out of the reach and sight of children.
What do I do if the liquid in the EpiPen® Auto-Injector is discoloured?

Occasionally inspect the EpiPen® solution through the viewing window.

The solution should always be clear. Discoloured EpiPen® Auto-Injectors should not be used.

Replace your EpiPen® Auto-Injector if you see:

  • Discoloured or brown solution
  • Solid particles (also called precipitate)
  • Any signs of leakage or damage to the carrier

Ask your pharmacist or physician about how to properly dispose of an EpiPen® Auto-Injector that’s discoloured, used, or expired. Never try taking the auto-injector apart.

Always replace your EpiPen® Auto-Injector before the expiration date or after using it.

Can you use EpiPen® if you have a sensitivity to sulphites?

This product contains sodium metabisulphite, a substance that may cause allergic-type reactions including anaphylactic symptoms or mild to severe asthmatic episodes in certain susceptible persons.

Epinephrine is the drug of choice for serious allergic reactions and the presence of a sulphite in this product should not prevent administration of the drug for treatment of serious allergic or other emergency situations, even if the patient is sulphite-sensitive.

Does EpiPen® contain latex?

No. EpiPen® is latex-free.

Can you purchase EpiPen® without a prescription?

In Canada, EpiPen® can be purchased with or without a prescription.

Does EpiPen® fit in most commercial carrying cases?

It is recommended to always carry EpiPen® in the plastic carrier tube provided when it is dispensed at the pharmacy. This carrier tube is designed specifically for EpiPen® and protects the device from UVB, accidental discharge and damage. However, EpiPen® will fit in most commercially available carrying cases. Please check with manufacturers for updates.

Can I travel with EpiPen®?

If travelling by air, always inform security that you are carrying an EpiPen® or EpiPen Jr® Auto-Injector and keep it in your hand luggage. The baggage compartment of the aircraft is not temperature controlled, so temperatures may not be ideal (25ºC/77ºF) or within the permitted range of 15º–30ºC (59º–86ºF).

Be sure to carry your EpiPen® or EpiPen Jr® Auto-Injector in its original carrier tube. You may also require a pharmacy label that includes the name of the person the pen was prescribed for and the name of the prescribing physician.

When travelling cross-border, please consult Canada Border Services at 1-800-461-9999 for the latest information, or visit their website.
