NAMI has recently started endorsing the Partnership
for Prescription Assistance , a new program that seeks to boost
enrollment in existing Patient Assistance Programs by helping consumers
identify and apply for programs for which they may be eligible. This
may be a good place to start if you are unfamiliar with Assistance
Programs that might work for you - however, we don't yet know how
successful the Partnership is at enrolling people in good programs,
or how much they may charge for their service. If anyone has experiences
to share about the Partnership for Prescription Assistance (good or
bad), please email the administration at: [email protected]

Appropriate dosage of Prolixin Decanoate (Fluphenazine Decanoate Injection) should be individualized for each patient and responses carefully monitored. No precise formula can be given to convert to use of Prolixin Decanoate; however, a controlled multicentered study,* in patients receiving oral doses from 5 to 60 mg fluphenazine hydrochloride daily, showed that 20 mg fluphenazine hydrochloride daily was equivalent to 25 mg (1 mL) Prolixin Decanoate every three weeks. This represents an approximate conversion ratio of mL ( mg) of decanoate every three weeks for every 10 mg of fluphenazine hydrochloride daily.
