Interrupts this pathway, preventing nausea before it fully ramps up.

Targeted, fast-actiong

Generally well-tolerated—why it’s so commonly paired with GLP-1s.

Important safety information
What you should know before taking compounded Semaglutide.

Ondansetron

Ondansetron is an FDA-approved prescription medication used to prevent and treat nausea and vomiting. It may be prescribed for off-label uses at a provider’s discretion.

WARNING

Please contact your doctor ASAP and seek in-person care immediately if a side effect becomes problematic or you experience:

  • Heart rhythm problems (QT prolongation): Irregular heartbeat, fast heartbeat, dizziness, fainting, or shortness of breath
  • Serotonin syndrome: Agitation, confusion, rapid heart rate, fever, sweating, muscle stiffness, tremor, or diarrhea—especially if taken with antidepressants (SSRIs, SNRIs), MAOIs, or other serotonergic medications
  • Severe allergic reactions: Swelling of the face, lips, tongue, or throat; difficulty breathing or swallowing; severe rash, hives, or itching
  • Severe constipation or bowel obstruction: Persistent abdominal pain, bloating, or inability to pass stool or gas
  • Liver Problems: Yellowing of the skin or the whites of the eyes (jaundice), dark urine, or pain in the upper right abdomen.
  • Severe headache or vision changes
  • Chest pain or pressure

Drug Interactions

As with other medications, ondansetron can interact with alcohol and certain prescription and non-prescription medications and herbal products.

  • Medications that affect heart rhythm: Increased risk of QT prolongation when combined with antiarrhythmics, certain antibiotics (e.g., macrolides), or antipsychotics
  • Serotonergic medications: Increased risk of serotonin syndrome when combined with SSRIs, SNRIs, MAOIs, triptans, or certain supplements
  • Apomorphine: Concomitant use is contraindicated due to risk of profound hypotension and loss of consciousness
  • Electrolyte-altering medications: Low potassium or magnesium may increase the risk of heart rhythm disturbances
  • CYP3A4 Inducers: Medications like phenytoin, carbamazepine, and rifampin may reduce the levels of ondansetron in your blood, making it less effective.

Please consult the pharmaceutical packaging for a full list of side effects, warnings, interactions, and additional information.

To report suspected adverse reactions to ondansetron, contact the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

In case of emergencies, please call 911 or go to the nearest emergency room.

Note: The above statements have not been evaluated by the Food and Drug Administration for off-label use. This product is not intended to diagnose, treat, cure, or prevent any disease.

IMPORTANT SAFETY INFORMATION

Tell your healthcare provider about your medical history prior to taking ondansetron, especially if you have:

  • A history of heart rhythm problems (QT prolongation, arrhythmias)
  • Low potassium or magnesium levels
  • Liver disease
  • A history of serotonin syndrome
  • Known allergies to ondansetron or similar medications
  • Are pregnant, planning to become pregnant, or breastfeeding. 

Use caution when consuming alcohol, as it may worsen side effects such as dizziness or drowsiness.

Never share ondansetron with other people.

Stop using ondansetron and get medical help right away if you are experiencing heart rhythm abnormalities or symptoms of a serious allergic reaction including swelling of your face, lips, tongue, or throat; problems breathing or swallowing; severe rash or itching; or fainting.

If you experience a medical emergency, call 911 or go to the nearest emergency room.
