What is the dosage of Benadryl for a moderate allergic reaction?

The correct dosage of Benadryl, or diphenhydramine, for a moderate allergic reaction is 50mg IV/IO/IM, which is typically administered over a period of 2 minutes. This dosing is based on established medical protocols that consider the efficacy of Benadryl in managing allergic reactions. Administering it intravenously or intramuscularly allows for faster absorption and quicker action, which is crucial in treating moderate allergic reactions where the patient may be experiencing symptoms such as hives, itching, or moderate respiratory distress.

The specific recommendation to administer the dosage over 2 minutes helps ensure that the medication is delivered safely and reduces the risk of potential side effects that might occur with a rapid injection. This method aligns with safe administration practices in emergency care settings, allowing for monitoring of the patient’s response to the medication after administration.

In contrast, the other options either administer the wrong dosage or route for a moderate reaction, or provide methods that are not standard for this specific situation. Understanding the correct protocols ensures that responders can effectively manage allergic reactions while maintaining patient safety.
