Dosage and Administration Instructions Administer Hydrocodone Polistirex and Chlorpheniramine Polistirex Extended-Release Suspension by the oral route only. Hydrocodone Polistirex and Chlorpheniramine Polistirex Extended-Release Suspension can be taken with or without food. Shake well before using. Do not mix Hydrocodone Polistirex and Chlorpheniramine Polistirex Extended-Release Suspension with other liquids or medicines.

Always use an accurate milliliter measuring device when administering Hydrocodone Polistirex and Chlorpheniramine Polistirex Extended-Release Suspension to ensure that the dose is measured and administered accurately. A household teaspoon is not an accurate measuring device and could lead to overdosage. The dosing cup is provided with the 3 oz (70 mL) and 4 oz (115 mL) packaged product. The dosing cup fills for 2.5 mL dose and for 5 mL dose. Instruct the patient to fill to the line that the dose has been prescribed. Do not fill over the dose prescribed. Rinse the measuring cup with water after each use. For prescriptions where a measuring device is not provided, a pharmacist can provide an appropriate measuring device and can provide instructions for measuring the correct dose. Do not overfill. Rinse the measuring device with water after each use. Advise patients not to increase the dose or dosing frequency of Hydrocodone Polistirex and Chlorpheniramine Polistirex Extended-Release Suspension because serious adverse events such as respiratory depression may occur with overdosage. The dosage of Hydrocodone Polistirex and Chlorpheniramine Polistirex Extended-Release Suspension should not be increased if cough fails to respond; an unresponsive cough should be reevaluated for possible underlying pathology.

When a patient who has been taking Hydrocodone Polistirex and Chlorpheniramine Polistirex Extended-Release Suspension regularly and may bephysically dependent no longer requires therapy with Hydrocodone Polistirex and Chlorpheniramine Polistirex Extended-Release Suspension, taper the dose gradually, by25% to 50% every 2 to 4 days, while monitoring carefully for signs and symptoms of withdrawal.
