Ondansetron (Ondem-MD 4 Tablet) is commonly used to prevent nausea and vomiting. Regarding its use in early pregnancy, some studies have raised concerns about a possible increased risk of birth defects, particularly involving the mouth and face, such as cleft palate or cleft lip. However, the evidence is not entirely consistent, and many healthcare providers weigh the benefits and risks carefully.

If you are pregnant or planning to become pregnant, it is very important to discuss with your doctor before taking ondansetron or any medication. Your doctor will consider your specific situation, the severity of your symptoms, and alternative treatments that may be safer during the first trimester.

In summary:

• There is some concern about potential risks with ondansetron in early pregnancy, but the data is mixed.
• Always consult your healthcare provider before using this medication if you are pregnant.
• Your doctor can help decide the safest option for you and your baby.

If you have any symptoms like severe nausea or vomiting during pregnancy, do not hesitate to seek medical advice promptly to ensure both your health and your baby's health are protected.
