Adrenalin Injection

Who is this for?

Epinephrine (also called adrenaline) is a powerful emergency medicine that works by quickly tightening blood vessels, opening up the airways, and making the heart beat stronger — it mimics the natural 'fight or flight' hormone your body produces.

Activates α1, α2, and β1-adrenergic receptors, causing vasoconstriction, increased cardiac contractility and heart rate, and bronchial smooth muscle relaxation. This restores blood pressure, cardiac output, and airway patency during life-threatening emergencies such as anaphylaxis, severe asthma, and cardiac arrest.

Is Epinephrine safe to take with another drug?

This is NOT a drug you take at home by yourself — it is given as an injection by a doctor or trained health worker in an emergency. For severe allergic reactions, the standard adult dose is 0.3 to 0.5 mg injected into the outer thigh muscle. Some people with known severe allergies carry auto-injector pens for emergencies, but this must be prescribed and demonstrated by a doctor.

Epinephrine is used only in emergencies, so there is no regular dosing schedule and no missed dose situation. If you carry an auto-injector for allergies, make sure it is always with you and has not expired.

• Fast or pounding heartbeat
• shakiness or trembling
• feeling anxious or restless
• headache
• dizziness

Beta-blocker drugs (like propranolol or atenolol used for high blood pressure) can reduce how well epinephrine works and may cause dangerous blood pressure changes. Some antidepressants (tricyclics like amitriptyline) can increase the effects of epinephrine dangerously. Avoid using with other stimulant drugs or excessive caffeine as this can overwork the heart.

Store at room temperature between 20°C and 25°C. Do not refrigerate or freeze. Protect from direct sunlight and heat — do not leave it in a hot car or near a window in Nigerian weather. Keep away from children. Check the solution regularly — if it looks brown or cloudy or has particles in it, do not use it and get a replacement.
