A new “one size fits most” diaphragm, Caya, was approved by the FDA in September 2014 and is now available in the US. This diaphragm has more flexible sizing than the traditional diaphragm and can be used for up to two years. When used with spermicide, Caya has the same moderate efficacy as the traditional diaphragm (88-94%).
This contoured, non-latex diaphragm comes in a single size and is available by prescription. Women who were fitted for a traditional diaphragm between 65mm and 80mm may use Caya. Women who have not used a diaphragm should see a provider for a fitting. In the clinical trial, 76% of participants were able to insert the device using only written instructions, and 94% were able to insert, position and remove the diaphragm when provided verbal instructions.
Many older diaphragms have been discontinued, but the Milex Wide Seal is still available in the US. It must be ordered after a fitting, through a clinician’s office. Caya is available for providers through HRSPx and clinicians can stock it in their offices for wider accessibility.
