Compare Delsym vs. Benadryl
Head-to-head comparisons of medication uses, side effects, ratings, and more.
Delsym (Dextromethorphan) is a good option for treating dry cough. It's not safe to take with MAO inhibitors though.
Benadryl (Diphenhydramine) is great for allergies, but curl up on the couch after taking it and get ready for a nap.
- Good for treating dry cough.
- Available in drugstores either by itself or in combination with other medications to treat cold and allergy symptoms.
- Available as a liquid and a tablet.

- Benadryl (Diphenhydramine) is often better than other antihistamines at treating allergy symptoms and hives.
- It can provide quick relief of allergy symptoms for both kids and adults.
- It makes you sleepy, so it'll help if your allergies are bothering you at night.

- Can't take dextromethorphan if you're taking MAO inhibitors (drugs used to treat Parkinson's disease, depression, and other emotional conditions). If taken together, they will cause dangerously high blood pressure levels.
