An EpiPen is used to inject a measured dose of epinephrine (adrenaline) into the body. It is used for the emergency treatment of anaphylaxis, a potentially fatal allergic reaction. This device is a lifesaver for many because allergies related to food are rising everywhere.
It is also important to know how long it is safe to use EpiPens in emergencies as many deaths occur over accidental food consumption.
How Long Do Epipens Last?
|EpiPen expiration||1 year|
|EpiPen injection effectiveness||30 minutes to 60 minutes|
An EpiPen is a device that can deliver a dose of epinephrine (adrenaline) to someone experiencing a severe allergic reaction. It is an auto-injector, which means anyone can use it, regardless of medical training. Epinephrine is the first-line treatment for anaphylaxis, a life-threatening allergic reaction.
The EpiPen contains a preloaded syringe of epinephrine and an automatic injection mechanism. When the EpiPen is placed against the thigh and activated, the needle pierces the skin and delivers the epinephrine into the muscle. The person experiencing the allergic reaction should then feel relief within minutes.
Epinephrine has a half-life of about two minutes, so it is essentially gone from the body after about 10 minutes. However, the effects of epinephrine may last for several hours.
EpiPens are good for about four hours after they are first used. After that, they may not be as effective in reversing anaphylaxis. If one has an EpiPen and it’s been more than four hours since first use, one should go to the emergency room and get a new one.
The expiration dates for most medicines are usually set at two or three years from the time of manufacture. EpiPens have a significantly shorter shelf life than other auto-injectors.
When it comes to how long it lasts without use, it can last up to 1 year from the date of manufacture. To prolong the shelf life, most experts recommended storing it in a cool and dark place. This is because epinephrine can break down with exposure to light, heat, and high temperatures.
Why Would Epipens Last So Long?
EpiPens are made with a drug called epinephrine. The expiration date on the EpiPen is based on how long it takes for the drug to break down and lose its effectiveness.
The FDA recommends that people keep their EpiPens in a cold, dry place and not use them past the expiration date.
Overall, the expiration date for EpiPens is one year because it is a prescription drug. After a year, the epinephrine in the EpiPen may not be effective anymore. Expiration dates indicate when the full strength and safety of a drug may begin to decline.
However, according to a study, expired epinephrine is still safe. The medication will remain effective after the expiration date but with less drug, and one can store it at room temperature. However, it’s important to note that the shelf life of epinephrine may vary depending on the manufacturer, so please consult the specific product’s instructions.
The benefits of using an EpiPen are:
- It can save one’s life in a severe allergic reaction.
- It is easy to use and easy to self-administer.
- It is preloaded with epinephrine, so one doesn’t have to worry about mixing the drug and having it ready in an emergency.
- It is small and lightweight, so it’s easy to carry wherever one goes.
Overall, epinephrine is the preferred treatment for anaphylaxis in many countries, a life-threatening allergic reaction. It is a hormone produced by the adrenal gland, and it works by narrowing the blood vessels and bronchioles. This helps improve breathing and reduces the amount of swelling in the area.
If one is at risk of anaphylaxis (due to a history of serious allergic reactions), a doctor may prescribe an EpiPen to carry with oneself.
An EpiPen is a self-injectable medication that contains epinephrine, a hormone that narrows blood vessels and opens airways in the lungs.
Epinephrine also stimulates the heart to beat faster. When injected into the thigh muscle, it quickly relaxes the muscles. This can help relieve symptoms of anaphylaxis such as difficulty breathing, chest pain, and other symptoms.
