Medically reviewed by Last updated on Jan 10, 2024.

Important Dosage and Administration Instructions

Administer TUXARIN ER by the oral route only.

Advise patients not to increase the dose or dosing frequency of TUXARIN ER because serious adverse events such as respiratory depression may occur with overdosage [see Warnings and Precautions (5.2), Overdosage (10)]. The dosage of TUXARIN ER should not be increased if cough fails to respond; an unresponsive cough should be reevaluated for possible underlying pathology [see Dosage and Administration (2.3), Warnings and Precautions (5.5)].

Recommended Dosage

Adults 18 years of age and older: one tablet every 12 hours as needed, not to exceed 2 tablets in 24 hours.

Monitoring, Maintenance, and Discontinuation of Therapy

Prescribe TUXARIN ER for the shortest duration that is consistent with individual patient treatment goals [see Warnings and Precautions (5.1)]

Monitor patients closely for respiratory depression, especially within the first 24-72 hours of initiating therapy [see Warnings and Precautions (5.2)].

Reevaluate patients with unresponsive cough in 5 days or sooner for possible underlying pathology, such as foreign body or lower respiratory tract disease [see Warnings and Precautions (5.5)]. If a patient requires a refill, reevaluate the cause of the cough and assess the need for continued treatment with TUXARIN ER, the relative incidence of adverse reactions, and the development of addiction, abuse, or misuse [see Warnings and Precautions (5.1)].

Do not abruptly discontinue TUXARIN ER in a physically-dependent patient [see Drug Abuse and Dependence (9.3)]. When a patient who has been taking TUXARIN ER regularly and may be physically dependent no longer requires therapy with TUXARIN ER, taper the dose gradually, by 25% to 50% every 2 to 4 days, while monitoring carefully for signs and symptoms of withdrawal. If the patient develops these signs or symptoms, raise the dose to the previous level and taper more slowly, either by increasing the interval between decreases, decreasing the amount of change in dose, or both.
