Are you tired of using makeshift devices, pillows, nasal strips, oral devices, and sprays to try and stop your snoring? If so then simple, disposable, convenient, clinically proven Theravent Patches may be your dream come true! Theravent is available WITHOUT a prescription, but it uses the same patented MicroValve Technology as Provent Therapy, a prescription product for the treatment of obstructive sleep apnea.
