How many milligrams of codeine can a consumer purchase in a schedule V cough syrup over-the-counter in 48 hours?

The correct answer is based on regulations that govern the sale of schedule V substances. A consumer is allowed to purchase a maximum of 200 mg of codeine per 100 mL or per 100 grams in a schedule V cough syrup, which translates to a maximum of 300 mg in a 48-hour period when considering common dosing limits.

The maximum amount a person can purchase over the counter within 48 hours typically allows for 250 mg, but given that the question is asking specifically about the allowances in Ohio, it’s crucial to adhere to the specifics set forth in the state’s laws regarding such substances.

Understanding that schedule V substances may have more stringent rules helps clarify why this limit is set and emphasizes the importance of regulatory compliance in pharmacy practice. Thus, in this context, option C reflects the regulatory framework governing the sale of codeine-containing cough syrups in Ohio.
