What could be the maximum days supply for the prescription of Tussionex if taken at the recommended dosage?

To determine the maximum days supply for a prescription of Tussionex based on its recommended dosage, it's important to consider the typical dosing guidelines and the formulation of the medication. Tussionex contains hydrocodone and chlorpheniramine and is often prescribed for the relief of cough and allergy symptoms.

The recommended dosage typically involves taking Tussionex every 12 hours. If the standard prescription is for a bottle containing a specific number of milliliters (commonly 240 mL) and the dosing involves taking a certain volume for each dose (like 5 mL), then the calculation for the maximum days supply would follow.

For instance, if a patient is instructed to take 5 mL every 12 hours, that equates to two doses per day, resulting in a total of 10 mL used each day. With a 240 mL bottle, you would do the following calculation:

240 mL divided by 10 mL per day equals a 24-day supply.

However, considering that Tussionex has a controlled substance component (hydrocodone), and state regulations regarding controlled substances often restrict the quantity dispensed more than standard prescriptions, it may be limited to a shorter supply.
