Adrenaline

Adrenaline, also known as epinephrine, is a life-saving medication used in emergency medical situations. It is commonly administered during severe allergic reactions (anaphylaxis), cardiac arrest, and asthma attacks. Adrenaline works quickly to restore heart function, relax airway muscles, and improve breathing. As a hormone and neurotransmitter, it plays a vital role in the body’s "fight or flight" response, increasing heart rate, blood pressure, and oxygen flow during stressful conditions.

Uses of Adrenaline

• Treatment of severe allergic reactions (anaphylaxis)
• Emergency treatment in cardiac arrest
• Management of acute asthma attacks
• Control of superficial bleeding during surgery
• Used with local anesthetics to prolong effect

How Adrenaline works

Adrenaline stimulates alpha and beta-adrenergic receptors in the body. This leads to increased heart rate, blood pressure, and airway relaxation, making it effective in treating anaphylaxis and cardiac arrest.

Benefits of Adrenaline

• Rapid action in life-threatening emergencies
• Restores normal heart rhythm during cardiac arrest
• Relieves severe allergic symptoms quickly
• Helps open airways during severe asthma attacks
• Can be used in multiple emergency scenarios

How to take Adrenaline

Adrenaline is usually given as an injection under the skin (subcutaneous), into the muscle (intramuscular), or directly into a vein (intravenous) by a healthcare professional. In emergency kits, auto-injectors are used for immediate administration. Always follow your doctor’s or emergency responder’s instructions.

Type of Dosage Available

• Injection (ampoules or vials)
• Auto-injector (for anaphylaxis)

Side effects of Adrenaline

• Increased heart rate (tachycardia)
• High blood pressure
• Anxiety or restlessness
• Tremors
• Headache
• Pale skin
• Irregular heartbeat (arrhythmia)

Safety advice

• Use only as directed by a healthcare provider
• Do not self-inject unless prescribed (e.g., auto-injector)
• Inform doctor if you have heart disease or hypertension
• Pregnant or breastfeeding women should consult a doctor
• Store auto-injectors at room temperature away from light

Frequently Asked Questions (FAQs)

Q: What is Adrenaline used for?
A: Adrenaline is used in emergencies such as severe allergic reactions, cardiac arrest, and asthma attacks to stabilize the patient quickly.

Q: How is Adrenaline administered?
A: It is usually given as an injection under the skin, into the muscle, or intravenously in hospital settings. Auto-injectors are available for personal emergency use.

Q: Is Adrenaline safe for children?
A: Yes, pediatric doses are available, especially in auto-injector form, but it should only be given under medical supervision or as prescribed.

Q: Can Adrenaline be self-injected?
A: Yes, auto-injectors (like EpiPen) are designed for self-use in emergencies, especially for people with a known history of severe allergies.

Q: What should I do after using an Adrenaline auto-injector?
A: Seek immediate medical help after using the injector, even if symptoms improve, as further monitoring or treatment may be needed.
