What is the function of adrenaline?
Adrenaline function is to treat acute allergic attacks (anaphylaxis) that are associated with insect bites or caused by certain foods, drugs, or other allergens.
Adrenaline automatic syringes can be used for self-injection – that is, injecting an individual himself – when experiencing an allergic attack.
Adrenaline is also used in the treatment of stress-induced anaphylactoid shock, or in the treatment of hypotension that may cause septic shock, or for other purposes not mentioned in the leaflet.
- Seek emergency medical care after using adrenaline to manage a severe allergic reaction as you will need to receive follow-up monitoring and treatment.
- Tell your doctor before taking adrenaline if your previous use of it made your attacks worse.
Tell your doctor if you have:
- Heart disease or high blood pressure
- Parkinson’s disease
- Depression or any mental illness
- A thyroid disorder
- Allergic attacks may affect the health of a pregnant or breastfeeding woman and the health of her fetus. Pregnant women may resort to using adrenaline during pregnancy or breastfeeding. Seek medical care when injecting adrenaline.
- In emergency cases, a pregnant woman may not be able to tell medical care providers about her pregnancy, so be sure to inform the doctor who monitors pregnancy about taking the medicine.
How to use adrenaline
- Adrenaline is injected into the skin or the outer side of the thigh muscle. In emergency cases, the injection can be applied without removing the clothing.
- Adrenaline can be given by infusion. The health care provider applies this mode of administration.
- Read carefully any directions for use provided with the medicine. Ask your doctor or pharmacist if you do not understand these instructions.
- Adrenaline auto-syringes are single-use administration systems.
- Follow all directions on the medicine label, read all directions included, and use the medicine as indicated.
- Do not inject adrenaline to children without medical guidance.
- Do not remove the protection cap until you are completely ready to inject, and do not place your fingers on the tip of the syringe after removing the protection cap.
To use an adrenaline auto-injector:
- Form a fist around the syringe with the syringe tip pointing down, and then remove the protective cap.
- Place the tip of the syringe on the muscular-lateral part of the thigh. The syringe can be applied without removing clothing. When injecting children, be sure to hold the leg tightly when applying the injection.
- Push the autoinjector toward the thigh to release the dose into the tissue. Hold the syringe in place for 10 seconds after applying the injection.
- Remove the autoinjector from the outside of the thigh and gently massage the injected area.
- Reinsert the used syringe, starting with the needle, into the pregnant tube, re-covering the tube, and keep it until the emergency room so that the health care provider knows how much adrenaline you have injected.
- Use the autoinjector only one time. Do not try to reuse the same syringe again if the needle comes out of the skin before 10 seconds have passed. The bent of the needle from the first use may cause serious skin injury.
- Seek health care after any adrenaline use. The adrenaline affects 10 to 20 minutes, and you will need extra care and monitoring afterward.
- Also, seek health care if you accidentally inject yourself with the needle when applying adrenaline to another person.
- A medicine box may come with a “training pen”. The practice pen contains no drug or needle and is used to practice drug application.
- Store the medicine at room temperature, away from light, heat, and moisture. Do not refrigerate or freeze the medicine, and do not store the medicine in the car.
- Do not use the medicine if its color has changed, or if you notice the appearance of particles in the solution, or if the expiration date mentioned on the label has expired, and contact the pharmacist to get another sample.
What might happen if a dose is missed?
Because adrenaline is used when needed, the drug does not keep the patient on a specific schedule.
What happens in case of an overdose?
Seek emergency health care.
Symptoms associated with overdosage may include: numbness, weakness, severe headache, blurred vision, strong pounding sounds in the ear, sweating, chills, chest pain, fast or slow heartbeat, severe shortness of breath, or coughing with foamy mucus.
What should I avoid when using adrenaline?
Do not inject adrenaline into a vein or the buttock muscle, as it may not have an effect. Inject the substance only into the lateral part of the thigh muscle.
Unintended injections of the hand or foot may cause blood flow to these areas to stop, which may cause numbness.
Adrenaline side effects
Before using adrenaline, tell your doctor if any allergic attacks get worse with previous use.
Call your doctor right away if you notice pain, swelling, warmth, redness, or other signs of injection on the injected area.
Common side effects include:
- difficulty breathing.
- Paleness and sweating.
- Nausea and vomiting.
- Asthenia and fatigue.
- Stress, anxiety, or fear.
