Generalized insulin allergy is rare. Symptoms occur immediately after the injection and include urticaria, angioedema, pruritus, bronchospasm, and, rarely, circulatory shock. As a rule, allergy may be treated with antihistamines. Some cases may require epinephrine and intravenous (IV) steroids.
Is short-acting and rapid-acting insulin the same?
Rapid-acting insulin also comes in a form that can be inhaled through the mouth. Short-acting insulins take effect and wear off more quickly than long-acting insulins. A short-acting insulin is often used 30 minutes before a meal so that it has time to work.

Humulin N (human insulin) is injected underneath the skin (subcutaneously) twice per day. The number of units of insulin is different for each person. The dose depends on whether you’re using it for type 1 diabetes or type 2 diabetes, your weight, how well you respond to insulin, and your blood sugar levels.
