Prescription or CPAP Supply Requests

Please call or fax Guadalupe Sleep Center with requests for prescription refills or to request CPAP supplies.  Guadalupe Sleep Center does not distribute CPAP supplies, but will send a prescription to a Durable Medical Equipment supplier on your behalf.

Dr. Duhon has a long-standing policy that patients must see him at least once yearly to remain in his care.  If you have not seen Dr. Duhon in the last 11 months, a staff member at Guadalupe Sleep Center will contact you to set up an appointment.  In some cases, I will not authorize prescriptions for medications or CPAP until the patient has made an annual appointment.
