Ondansetron is an anti-nausea commonly prescribed to migraine sufferers. It’s used to treat moderate to severe nausea and vomiting. It’s commonly marketed under the brand name Zofran®. While it was originally developed to help with nausea and vomiting associated with chemotherapy treatments, it’s now also used for other types of nausea—including postoperative nausea and nausea resulting from migraines or common migraine medications.
Ondansetron is a prescription medication, which means you can’t get it over the counter. It must be prescribed by a healthcare professional. Get started today with a Cove doctor consultation.
Ondansetron is part of a class of medications called serotonin 5-HT3 receptor antagonists. That’s a fancy way of saying that ondansetron blocks the action and effects of serotonin, a natural chemical in your body that can cause nausea and vomiting.
If this is your first dose, it’s normal to have some questions about how to properly take this medication. Fortunately, it’s straightforward. Ondansetron can be taken with or without food and water (which is good news when you’re already feeling sick to your stomach).
Generally, ondansetron is well-tolerated and has few serious side effects, especially when taken on an infrequent, as-needed basis. However, you should tell your doctor if you have a known allergy to ondansetron or any of its ingredients so that you can avoid a potential allergic reaction.
Tell your doctor if you are pregnant, planning to become pregnant, or are breastfeeding. While some doctors do prescribe ondansetron to treat nausea and morning sickness during pregnancy, definitive studies about the safety of this medication in pregnancy are difficult to find. ondansetron is FDA-approved, but not for treating morning sickness.
Of course, it’s smart to inform your healthcare providers of all of your medical conditions, as well as all of the medications—both prescription and over the counter—you are currently taking.
Let your doctor know if you have been taking ondansetron more than a few times each week.
Yes, it’s safe to take ondansetron along with any other migraine medications. It does not interfere or alter the effectiveness of those other treatments or medications.
Keep ondansetron in its package until you are ready to take it. It should be stored in a dry place at room temperature, and should also be protected from direct light.
