Zofran odt?

Do you mean Zofran ODT (ondansetron orally disintegrating tablets)? If so, here’s a quick overview:

What it’s for

• Prevents and treats nausea and vomiting, commonly from:
  • chemotherapy
  • radiation
  • surgery
  • sometimes gastroenteritis (off-label)

How it works

• It’s an anti-nausea medicine (a serotonin 5‑HT3 receptor antagonist).

How to take the ODT

• Keep the tablet in the blister until you’re ready.
• With dry hands, peel the backing and place it on your tongue.
• Let it dissolve—don’t chew or swallow whole.
• You can usually take it with or without food.

Common side effects

• Headache
• Constipation or diarrhea
• Dizziness
• Fatigue

Important cautions (key ones)

• It can affect heart rhythm (QT prolongation), especially if you:
  • have heart rhythm problems
  • have low potassium/magnesium
  • take other QT‑prolonging meds
• Tell your clinician/pharmacist if you’re on meds like some antibiotics (e.g., azithromycin), antipsychotics, methadone, or others that can prolong QT.

When to get urgent help

• Fainting, severe dizziness, or a very fast/irregular heartbeat
• Signs of allergic reaction (swelling, trouble breathing, hives)

If you tell me:

1. the dose strength (e.g., 4 mg or 8 mg),
2. why you’re taking it (vomiting from what cause), and
3. your age and any heart conditions/other meds,
   I can give more specific, safer guidance.
