Always follow your doctor’s instructions precisely. The typical adult dose for nausea and vomiting is 25-50 mg every 4-6 hours as needed, not exceeding 150 mg daily. For insomnia, a single dose of 25 mg before bedtime is common. Children’s dosages are significantly lower and strictly determined by weight and age; consult your pediatrician.

Important Considerations
Do not exceed the prescribed dosage. Overdosing can lead to serious health risks. Report any unusual side effects immediately to your doctor or pharmacist.

Discuss potential drug interactions with your physician before combining it with other medications, especially antidepressants, opioids, or alcohol.
