How much codeine to suppress cough in adults?

In adults, codeine is typically used at a dose of 10 to 20 mg every 4 to 6 hours as needed for cough suppression, not exceeding 120 mg per day. However, due to potential side effects and the risk of dependence, it is important for individuals to consult a healthcare provider for personalized dosing and recommendations. Codeine should be used cautiously, particularly in those with respiratory issues or a history of substance use disorder. Always follow a doctor's guidance when using medications like codeine.
