Compazine Alternatives: Effective Options for Nausea and Vomiting

When Compazine, a brand name for the antiemetic drug prochlorperazine used to treat nausea, vomiting, and migraines. Also known as prochlorperazine, it helps calm the brain’s vomiting center—but it’s not the only option. Many people need alternatives because of side effects like drowsiness, muscle stiffness, or movement disorders. If you’ve been told to switch from Compazine, you’re not alone. Doctors regularly turn to other antiemetics that work just as well—or better—with fewer risks.

One of the most common ondansetron, a serotonin blocker used to prevent nausea from chemotherapy, surgery, or stomach bugs. Also known as Zofran, it is often preferred because it doesn’t cause the same movement issues as Compazine. Then there’s metoclopramide, a drug that speeds up stomach emptying and blocks nausea signals in the brain. Also known as Reglan, it works fast for nausea tied to slow digestion or reflux. For milder cases, dimenhydrinate (Dramamine) or meclizine (Bonine) might do the trick without needing a prescription. Each has its place: ondansetron for severe nausea, metoclopramide for digestive delays, and OTC options for motion sickness or mild stomach upset.

What you choose depends on why you’re nauseated. Chemotherapy? Ondansetron leads the pack. Migraine-related nausea? Compazine still works, but ondansetron and metoclopramide are safer long-term. Post-surgery? Often ondansetron. Pregnancy? Doxylamine and vitamin B6 are first-line, not Compazine. And if you’re worried about dizziness or muscle tightness, skipping Compazine entirely makes sense. The good news? You have real choices. Below, you’ll find detailed comparisons of these drugs side-by-side—what they do, how they stack up, and which one fits your situation best.
