When can my patient expect their medication?

Upon receipt, prescriptions are processed and prepared for shipping by the end of the next business day. Once processed, medications are shipped – at no cost – to the patient via USPS Priority Mail (arrives in 2-5 days depending on location) or your facility (2-day FedEx). Expedited shipping is available for an added fee. If you have immediate needs, please contact us at (855) 466-1076.


When can patients contact OSRX to submit payment or check a prescription's status? 

Patients need to wait two business days following the submission of their prescription before contacting OSRX to check the status of their prescription or pay their bill. After that two-day processing period has passed, patients can pay for their medication quickly and easily online. We also accept payment via phone at (855) 466-1076. When necessary, our staff will attempt to contact patients up to three times via phone to confirm shipping addresses and/or request payment. 


How can patients pay for their medication?

Patients have the option to pay for their medication on our website -- click the Patient Payment button on top of the homepage -- or by calling our staff at (855) 466-1076. Online payment is the quickest and easiest of the two options -- patients simply enter their phone number, date of birth and payment amount (invoice number is not required). Patients should wait two business days following the submission of their prescription before contacting OSRX or paying online. This two-day grace period allows us to properly verify and enter the prescription into our system. We appreciate your understanding and cooperation.
