Compare Phenergan vs. scopolamine
Head-to-head comparisons of medication uses, side effects, ratings, and more.
Phenergan (Promethazine) is used to treat and prevent nausea and vomiting from surgery, motion sickness, or pregnancy. While it's cheap and available in different forms to make it easier to take, it can make you feel very sleepy, and its side effects mean that children under 2 and adults over 65 shouldn't take it.
Transderm-Scop (scopolamine) is a low-hassle patch that works well to prevent nausea and vomiting, but it takes several hours to work.
- Available in generic.
- Available as a syrup or tablet that you can take by mouth, or as a rectal suppository if you're unable to take anything by mouth.
- Transderm-Scop (scopolamine) is well tolerated.
- Prevents nausea for 3 days.
- Because Transderm-Scop (scopolamine) is a skin patch, it's a good alternative to stopping nausea and vomiting if you're not able to swallow pills.
- Can make you feel very sleepy, especially if you're taking other drugs that can make you sleepy or if you drink alcohol.
- Can't be used in children under 2 years of age or if you're over 65 because of increased risk from side effects.
- Can make your skin more sensitive to the sun.
- Can only be used for prevention of nausea and vomiting. It can't stop nausea or vomiting that's already happening.
- The side effects can be worse if you are 65 and older.
- You might feel sleepy, drowsy, or have blurry vision while taking Transderm-Scop (scopolamine). Taking alcohol or other medicines that make you drowsy can make this effect worse.
- You're more likely to have heat stroke or feel dehydrated.
- It takes a few hours for Transderm-Scop (scopolamine) to kick in, so you have to remember to take it beforehand.
