EpiPen is an emergency auto-injection with a dose of adrenaline. It contains a quick-acting drug calleadrenaline which is administered to people suffering from a severe allergic reaction in an emergency.

EpiPen is used to treat severe allergic reactions known as anaphylaxis to certain foods, drugs, insect bites or stings and other allergens.

EpiPen contains the drug adrenaline which narrows the blood vessels and opens up the airways in the lungs. This helps reverse allergic reaction symptoms such as severe redness or skin itching, severe low blood pressure, hives, wheezing, and more.

EpiPen is a quick-acting injection that helps reverse a severe allergic reaction and its symptoms by:

  • Increasing lowered blood pressure

  • Stabilising the heart rate

  • Reversing hives

  • Subsiding the swelling of the nose, lips or throat

EpiPen is a life-saving injectable drug given during an emergency.

The dosage of EpiPen is determined as per the subject’s body weight.

  • Patients greater than or equal to 30 kg in weight should use EpiPen 0.3 mg.

  • Patients weighing 15 to 30 kg should use EpiPen Jr. 0.15 mg.

  • EpiPens should only be used by patients who have seen their usual GP or an allergy clinic and have been advised that carrying or using an EpiPen is the safest option for them and is clinically appropriate.

  • Note that EpiPen is a medication that is to be administered only during an emergency or a severe anaphylactic reaction. It is for one-time use and should be disposed of properly after use.

  • If you inject the EpiPen auto-injector accidentally into your hands, fingers or feet it may result in injury to this area. Seek emergency medical treatment immediately.

  • Never touch the orange tip of the EpiPen and do not remove the blue safety cap until you are ready to use it.

  • Always keep the EpiPen in its outer container, this protects it from light. When adrenaline is exposed to air or light, it can become compromised and deteriorate rapidly and may turn pink or brown.

  • Check the expiry date on your EpiPen. Also, check the contents from time to time to ensure that the solution is clear and colourless. If the solution is discoloured or contains residual particles or if your pen has expired, get a new prescription from your doctor and return the EpiPen to your pharmacist.

Use EpiPen only during a severe anaphylactic reaction that has been triggered due to exposure to an allergen. Symptoms may include:

  • Difficulty in breathing

  • Increased heart rate

  • Wheezing

  • Hives

  • Rapidly increasing widespread rash

  • Swelling of the throat, nose or lips

  • Severe skin itching

An EpiPen can safely be administered by a patient by themselves once they have been shown how to use it and have been trained. It is a good idea to make sure those who you spend the most time with are aware of how to use it in case of emergency. It’s important to use the EpiPen only as instructed by your doctor. EpiPen can be injected through clothes if the need arises.

Follow the steps as below:

  • Remove the blue cap and then inject the orange tip of the EpiPen firmly into the outer thigh at a right angle, from about 10cm. This will release a spring-activated plunger which will then push the hidden needle into the thigh muscle to administer a dose of adrenaline. You will hear a click sound. Hold the pen firmly in the thigh for about 10 seconds before removing it.

  • Gently massage the area where you have injected the EpiPen for about 10 seconds. This will help improve the absorption of the adrenaline.

  • Be careful to inject EpiPen only into the outer side of the thigh. It should not be injected into the buttock or any vein.

  • Call an ambulance every time you use the EpiPen, even if you feel that the symptoms are improving. The effects of the EpiPen will last for about 5 – 10 minutes, after which the patient will need proper treatment.

  • The person who has been administered a dose of the EpiPen should lie down with legs raised. If possible, do not leave the patient alone.

  • If the symptoms of the allergic reaction do not show signs of improvement or if they worsen, then use a second EpiPen about 5 to 10 minutes after the first one.

Adrenaline is the key ingredient of EpiPen and a quick-acting substance to tackle anaphylaxis. Patients with the following conditions should use this drug with caution:

  • Heart disease or an irregular heartbeat (arrhythmias)

  • Hypertension (high blood pressure)

  • Overactive thyroid gland (hyperthyroidism)

  • Tumour of the adrenal gland (known as a pheochromocytoma)

  • Diabetes

  • Glaucoma

  • High calcium or low potassium in the blood

  • Allergy to sodium metabisulphite (used as a preservative in this product)

  • Elderly people

Some common side effects of EpiPen include:

  • Headache

  • Vomiting and nausea

  • Paleness

  • Weakness

  • Dizziness

  • Anxiety and nervousness

  • Sweating

  • Increased palpitations

  • Tremors, usually of the hands

EpiPen can increase the risk of side effects on the heart if you are already taking any of the following medicines:

  • beta-blockers such as propranolol

  • digoxin

  • MAOI antidepressants e.g. phenelzine, tranylcypromine, isocarboxazid, moclobemide

  • tricyclic antidepressants e.g. amitriptyline

  • entacapone

  • selegiline

  • quinidine

  • rasagiline

The adrenaline present in EpiPen can also decrease the level of insulin in the body and result in an increased level of blood sugar.

EpiPen should not be exposed to light or air, it should be kept in its glass cartridge. Store it below 25°C. Do not refrigerate or freeze.
