Jext

Jext is a pre-filled auto-injector pen designed to be used when someone with serious allergies suffers an anaphylactic shock. The pen contains adrenaline and is injected into the thigh muscle by the patient themselves or by someone else if necessary.

Jext is very similar to an EpiPen, which is also popularly used by people with allergies that can lead to anaphylaxis. Both medications use the same ingredient and are used in the same way.

What is Jext?

Jext is an adrenaline auto-injector used by people with potentially serious allergies that’s designed to treat anaphylaxis (also known as anaphylactic shock). The prefilled pen is prescribed to patients so that they can carry it with them at all times. It is used in emergency situations when a patient begins having an anaphylactic reaction.

The pen is injected into the thigh muscle and should be administered as soon as signs of a serious allergic reaction begin appearing. It can be used either by the patient themselves if possible or someone helping them. Jext has the same ingredient found in EpiPen and it works in the same way. Emerade is another alternative auto-injector which can be used to treat anaphylaxis.

How does Jext work?

Inside a Jext pen is a sterile solution of adrenaline. This single dose is injected into the outer part of the thigh muscle (this process is known as an intramuscular injection).

The time to use Jext is when it’s noticeable that a patient is experiencing a sudden life threatening allergic reaction. Such a reaction could be triggered by a certain food or drug, exercise, or an insect sting or bite. The first symptoms of an anaphylactic shock usually take place within minutes of exposure to the allergen. Signs that anaphylaxis is taking place include:

  • Itching of the skin
  • Raised rash (similar to a nettle rash)
  • Flushing
  • Swelling of the lips, throat, tongue, hands and feet
  • Wheezing
  • Hoarseness
  • Shortness of breath
  • Nausea and vomiting
  • Stomach cramps
  • Loss of consciousness (in some severe cases)

If you need to administer Jext to yourself or someone else but you forget how to use it, you can read the instructions on the side of the pen itself.

What happens immediately after you use Jext?

When Jext needs to be used on a patient in response to anaphylaxis, this person will have difficulty moving and it’s important to ensure that this person is placed in a comfortable position.

If you are with someone who has an anaphylactic shock, then firstly make sure they get the auto-injection if they can’t apply themselves and then move them into an appropriate position if necessary. Most people should lie flat when they are experiencing anaphylaxis. However, if the patient is having trouble breathing then they should sit up to make breathing easier. Pregnant women who experience anaphylaxis should lie on their left side, in order to prevent putting too much pressure on the large vein that leads to the heart. A patient will need putting in the recovery position if they become unconscious following anaphylaxis.

When the Jext pen has been used and the effects of the anaphylactic shock are reduced to the point they are no longer life-threatening, the patient will need to go to hospital for observation. This usually lasts 6-12 hours and is necessary as the symptoms of anaphylaxis can potentially return not that long after the initial shock.

How much Jext should I use at once?

In some cases, an allergic reaction may require two pens to be used. Therefore, it is advised to patients with anaphylactic allergies that they carry two with them. If two pens are required to be used, they should be administered 5-15 minutes apart.

If you somehow end up overdosing on Jext, then you should seek immediate medical help. Your blood pressure could rise sharply and your heartbeat and kidney functions may become abnormal. You should also see your doctor when you can to get the used Jext replaced as soon as possible.

What are the side effects of Jext?

Like with all medicines, Jext can potentially cause side effects when used. If you experience any of them, it is best to inform your doctor as soon as possible so it can be determined if Jext is still okay for you to use.

The following potential side effects have been reported by users of Jext pens:

  • Irregular or rapid heartbeat
  • High blood pressure
  • Sweating
  • Nausea and vomiting
  • Trouble with breathing
  • Headaches, dizziness and fainting
  • Anxiety and hallucinations
  • Alterations to your blood such as increased sugar levels or decreased potassium levels

It has been reported as well that in cases where Jext is accidentally injected into hands or feet, a lack of blood supply can become an issue in these areas. It is best to seek medical help immediately if an accidental injection occurs, as there will be a small chance that a hypersensitivity reaction (leading to difficulty breathing, among other things) could occur.

Can I take Jext?

When a doctor prescribes you Jext, you should let them know if you have any of the following conditions listed:

  • Asthma
  • Heart disease
  • Overactive thyroid
  • High blood pressure
  • Diabetes
  • A tumour on the adrenal gland (phaeochromocytoma)
  • Increased pressure in the eye (glaucoma)
  • Renal or prostate disease
  • Low potassium levels or high calcium levels in your blood

Having these conditions won’t necessarily prevent you from taking Jext, but the doctor will carefully assess whether or not it can be considered suitable treatment based on your condition. You should also inform your doctor if you’re pregnant, as you’ll be at greater risk of experiencing the side effects associated with Jext.
