If it is almost time for your next dose, skip the missed dose and take the medicine at your next regularly scheduled time. Do not take extra medicine to make up the missed dose.

What happens if I overdose (Promethazine HCl and Dextromethorphan Hydrobromide Syrup)?

Seek emergency medical attention if you think you have used too much of this medicine.
