Introduction
Diphenhydramine is an over-the-counter medication commonly used to treat allergies, colds, and sleep disorders. It’s also found in some combination products such as Nyquil and Tylenol PM. While it can be effective for treating these conditions, it’s important to understand the recommended dosages and potential side effects that can come with taking too much.
Overview of Diphenhydramine Dosage Recommendations
The recommended dose of diphenhydramine for adults and children 12 years and older is 25 to 50 mg every four to six hours, or up to 300 mg per day. For children ages 6 to 11, the recommended dose is 12.5 to 25 mg every four to six hours, not exceeding 150 mg per day. Children under 6 years old should not take diphenhydramine.

Diphenhydramine is generally considered safe when taken as directed. Studies have shown that it can help reduce symptoms of allergies, colds, and insomnia.

However, like all medications, there are some potential risks associated with taking diphenhydramine. Possible side effects include drowsiness, dizziness, dry mouth, constipation, and difficulty urinating. It can also interact with other medications and may cause confusion or agitation in some people.
