Fioricet Prescription Quantity at One Time
No specific U.S. federal limit exists that sets a maximum number of Fioricet (butalbital/acetaminophen/caffeine) tablets that can be ordered on a single prescription solely by virtue of being a Schedule III product. [1]
Maximum Daily Dosage From Product Labeling
Fioricet (butalbital/acetaminophen/caffeine) is labeled as 1 or 2 tablets (or capsules) every 4 hours as needed, with a total daily dosage not exceeding 6 tablets (or capsules) per day. [2]
Acetaminophen Daily Safety Limit
Fioricet labeling instructs not to take more than 4000 mg of acetaminophen per day. [3]
Practical Quantity Calculations Used for Prescribing
The labeled maximum of 6 tablets per day implies a maximum quantity of:
- 6 tablets for a 1-day supply. [2]
- 30 tablets for a 5-day supply. [2]
- 180 tablets for a 30-day supply at 6/day. [2]
Controlled-Substance Scheduling Context
Butalbital/acetaminophen/caffeine combination products are associated with DEA Schedule III controls in labeling for some formulations. [2]
Quantity Limits That Commonly Apply Beyond Federal Law
Actual quantities dispensed at one time can be constrained by state controlled-substance rules, pharmacy policies, and payer/plan “quantity limit” edits that are not part of drug labeling. [4]
Prescription Safety Monitoring Signals
Fioricet labeling notes hepatotoxicity risk with acetaminophen and does not support extended and repeated use because of physical dependence risk from butalbital. [3]
Next Step for a Definitive Number
A definitive “how many tablets can be ordered at one time” answer requires the specific state, the intended days’ supply, and the pharmacy and payer rules for that location and product formulation. [4]
