How to Write a Prescription for Clonazepam 0.75 mg PRN for Acute Anxiety

For a 10-day supply of clonazepam 0.75 mg to be taken as needed for acute anxiety or panic symptoms, write the prescription as: "Clonazepam 0.75 mg, take 1 tablet by mouth as needed for acute anxiety or panic, maximum 3 times daily, Dispense #30 tablets, No refills."

Prescription Writing Details

When writing a prescription for clonazepam (Klonopin) as needed for acute anxiety, follow these specific components:

• Patient Information: Full name, date of birth, address
• Medication Name: Clonazepam (or brand name Klonopin if preferred)
• Strength: 0.75 mg
• Dosage Form: Tablets
• Sig (Instructions): Take 1 tablet by mouth as needed for acute anxiety or panic symptoms
• Frequency: Maximum 3 times daily (based on FDA guidelines for panic disorder 1)
• Quantity: #30 tablets (for 10-day supply at maximum usage)
• Refills: No refills (or 0 refills)
• DEA Number: Required as clonazepam is a Schedule IV controlled substance
• Date: Current date
• Prescriber Information: Full name, address, phone number, signature

Dosage Considerations

The FDA label for clonazepam indicates that for panic disorder, the initial dose is typically 0.25 mg twice daily, which can be increased to a target dose of 1 mg/day 1. Your prescribed dose of 0.75 mg falls within this therapeutic range.

For PRN (as needed) use:

• Maximum daily dose should not exceed 4 mg per day according to the FDA label 1
• The 0.75 mg dose is appropriate for acute anxiety management
• Limiting to 3 times daily provides a maximum daily dose of 2.25 mg, which is well within safety parameters

Quantity Calculation

For a 10-day supply with maximum usage of 3 tablets per day:

• 3 tablets × 10 days = 30 tablets total

Important Prescribing Considerations

1. Controlled Substance Requirements:

   • Clonazepam is a Schedule IV controlled substance
   • Prescription must include your DEA number
   • Some states require prescriptions to be written on tamper-resistant prescription pads
   • E-prescribing may be required in certain jurisdictions

2. Patient Education Points:

   • Advise patient about potential sedation and not to drive or operate machinery after taking
   • Warn against combining with alcohol or other CNS depressants
   • Inform about potential for dependence with regular use

3. Documentation:

   • Document the indication for clonazepam in the patient's medical record
   • Note any previous benzodiazepine use and response
   • Record the treatment plan, including duration and follow-up

Cautions and Monitoring

• Be aware of the potential for dependence with benzodiazepines, even with short-term use
• Consider limiting the prescription to 10 days without refills to minimize risk of dependence
• Schedule a follow-up appointment to assess response and need for alternative treatments
• Document your clinical reasoning for choosing clonazepam over other anxiety management options

Remember that while clonazepam is effective for acute anxiety management, it should be used for the shortest duration possible while developing a longer-term management strategy for the patient's anxiety disorder.
