What are the side effects of adrenaline (epinephrine)?
In the doses we recommend, trembling, palpitations (feeling your heart beating fast), and a feeling of tension or anxiousness are quite likely to happen, though many people dont notice any of these things. These are normal effects of the adrenaline and soon wear off. Higher doses cause an extremely unpleasant feeling and may be dangerous to the heart. If you have some other medical conditions such as high blood pressure, or an abnormal heart rhythm, or narrowing of the coronary arteries, or if you are treated with some other medicines such as medicines for depression, special caution is needed with adrenaline, and a specialist should advise you.
