When Faxing Prescriptions Makes Sense
Despite electronic prescribing, many pharmacies still accept or require faxed prescriptions in specific situations:
- Mail-order pharmacies that accept faxed prescriptions for refills
- Specialty pharmacies handling compounded or specialty medications
- Prescription transfers between pharmacies when patient-initiated
- Supporting documentation for prior authorizations or medical necessity
- Rural or independent pharmacies with limited e-prescribing capabilities
Common pharmacy fax scenarios:
Important: Always verify the pharmacy's fax number before sending. For controlled substances, Schedule II can only be faxed for hospice and long-term care facility patients. Schedule III-V can generally be faxed but require manual (wet) prescriber signature. Always verify your state's regulations.

Pharmacy Fax Questions
Can I fax controlled substance prescriptions?
Schedule II prescriptions (opioids, Adderall, Ritalin) can only be faxed for hospice patients and long-term care facility residents - in these cases, the fax serves as the original prescription. Schedule III-V controlled substances can generally be faxed with the prescriber's manual (wet) signature. All other Schedule II prescriptions require the original signed prescription or e-prescribing with DEA EPCS certification.
Is OneFaxNow HIPAA compliant for prescription faxes?
Yes. OneFaxNow provides HIPAA-compliant faxing with instant digital BAA, encryption in transit and at rest, comprehensive audit logging, and secure file deletion after transmission. Unlike most services that charge $15-50/month for HIPAA tiers, OneFaxNow HIPAA Fax is just $6.50 or $10.00 per fax - no subscription required.
How do I fax a prior authorization to an insurance company?
Download the PA form from your PBM's website (CVS Caremark, Express Scripts, OptumRx, or your state Medicaid), complete it with required clinical documentation, and fax to the number on the form. PA requests typically receive a response within 24 hours. OneFaxNow provides HIPAA-compliant transmission with audit logs for compliance documentation.
What if the pharmacy fax line is busy?
Pharmacy fax lines—especially at busy retail locations—can be frequently occupied. OneFaxNow automatically retries your fax up to three times with intelligent spacing. You'll see each attempt on your Fax Status page. If all attempts fail, you pay $0.
Can patients fax their own prescriptions?
Patients can fax non-controlled prescription copies to pharmacies for transfers or records purposes, but the pharmacy typically needs to verify with the original prescriber. For new prescriptions, the fax should generally come from the prescriber's office. Check with your pharmacy about their specific policies.
Do you support mail-order and specialty pharmacies?
Yes. OneFaxNow works with any U.S. or Canada pharmacy fax number, including mail-order pharmacies (Express Scripts, CVS Caremark, OptumRx, etc.) and specialty pharmacies. Just enter the pharmacy's fax number and we handle the transmission with full HIPAA compliance.
How long do you keep my prescription documents?
Files are securely deleted after fax transmission completes. We retain only the delivery confirmation and audit log records required for HIPAA compliance—never the prescription content itself. BAA documentation is stored securely for 7 years per HIPAA requirements.
