If Diclectin is not working for your vomiting, it is important to consult with your pharmacist or doctor to explore other treatment options. Other medications, dosage adjustments, or different methods of administration may be considered. In some cases, it may be recommended to suspend vitamin intake during severe nausea and resume once symptoms are better controlled. Taking folic acid alone during this period may also be suggested. If you have any further questions, do not hesitate to reach out to a healthcare professional for guidance.
