Liquid Benadryl, also known as diphenhydramine, is an antihistamine commonly used to relieve allergy symptoms, such as itching, sneezing, and runny nose. While it is widely available over-the-counter (OTC), it's essential to understand the proper dosage and usage guidelines, especially for adults. In this article, we will provide a comprehensive guide to help you navigate the safe usage of liquid Benadryl for adults.
Benadryl is available in various forms, including tablets, capsules, and liquid. The liquid form is often preferred by adults who have difficulty swallowing pills or need a more precise dosage.

The general guideline is to take 1-2 teaspoons (5-10 mL) every 4-6 hours, not to exceed 4 doses in 24 hours. However, it's essential to consult the label or a healthcare professional for specific instructions.
