How should this medicine be used?

Chlorphen-12 comes as an extended-release (long-acting) tablet and is usually taken twice a day in the morning and evening as needed. Follow the directions on the package carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Chlorphen-12 exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Check nonprescription cough and cold product labels carefully before using 2 or more products at the same time. These products may contain the same active ingredient(s) and taking them together could cause you to receive an overdose. This is especially important if you will be giving cough and cold medications to a child.

If you are giving Chlorphen-12 to a child, read the package label carefully to be sure that it is the right product for a child of that age. Before you give Chlorphen-12 to a child, check the package label to find out how much medication the child should receive. For children under 12 years, ask the doctor.

Swallow Chlorphen-12 tablets whole. Do not break, crush, chew, or open them.

Other uses for this medicine.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
