It is generally considered safe to take Ondansetron (Ondem-4) during pregnancy when prescribed by a doctor, especially after the first trimester.

🩺 Safety in Pregnancy

Ondansetron is classified as a Category B drug for pregnancy, meaning no proven risks have been found in clinical research. It is usually avoided during the first 12 weeks due to a small potential risk of oral cleft defects but is considered safe after that period if your doctor has prescribed it.

⚠️ Precautions and Monitoring

• Use Ondansetron only as directed by your doctor and avoid taking more than the prescribed dose.
• Monitor for any side effects such as nausea, fatigue, or unusual symptoms and report them to your doctor.
• Since you are in your fourth month, continuing the medication under medical supervision is appropriate.

🩺 When to Consult Your Doctor

If vomiting and nausea persist or worsen despite medication, or if you experience any new symptoms, consult your obstetrician promptly for further evaluation and management.
