Compare Delsym vs. Sudafed
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.
Sudafed (Pseudoephedrine) relieves stuffy nose, but it could keep you up at night. Don't forget your photo ID or you won't be able to buy it in the drugstore.
- 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.
- Some products relieve cough for up to 12 hours.
- One of the best over-the-counter options to clear stuffy nose and help you breathe better.

- Can be helpful in relieving congestion-related headaches and pressure in your ears.
- Available in regular and extended release forms.
- 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.
- If you're taking this in combination with other cold and allergy medications, you should read labels closely to make sure you're not accidentally taking too much of a single ingredient.
- Pseudoephedrine (a decongestant) can make your heart race or make you feel anxious and restless.
- It can affect the quality of your sleep, so you can't take it too close to going to bed.
- Can raise blood pressure so check with your doctor before using it if you have high blood pressure or other heart conditions.
- Sudafed (Pseudoephedrine) isn't as effective after using it for more than 4 days straight.
