Answer

**Step-by-Step Text Solution:**

1. **Identify the Substance**: Benadryl is the common name for the drug Diphenhydramine.

2. **Understand the Classification**: Benadryl is classified as an antihistamine. Antihistamines are medications that counteract the effects of histamine, a substance in the body that is involved in allergic reactions.

3. **Mechanism of Action**: When the body encounters an allergen, it produces histamine, which can lead to symptoms such as itching, redness, and swelling. Antihistamines like Benadryl work by blocking the action of histamine, thereby alleviating these symptoms.

4. **Common Uses**: Benadryl is primarily used to treat symptoms associated with allergies, such as:
- Itchy skin (e.g., from hives)
- Watery eyes
- Itchy nose and throat
- Runny nose
- Sneezing
- Symptoms of the common cold and flu

5. **Conclusion**: Therefore, Benadryl is used as an antihistamine to relieve allergy symptoms and is effective in treating conditions that involve histamine release.

**Final Answer**: Benadryl is used as an antihistamine.
