pulmonary hypertension
"My father has been on Revatio for 20 months. His quality of life is greatly improved from the standpoint of adverse side effects he was experiencing while on another PAH medication.  His breathing issues are still well controlled and there are no side effects.  As for high insurance copays, Pfizer( manufacturer of Revatio) has a terrific Patient Assistance Program that is based on income.  Apply online at Pfizer.com.  The form is available there and must be completed by patient and prescribing physician.  There is no reason not to ask for financial help when it is available for your medications.  Most manufacturers have assistance programs so do a little bit of research and ask your doctor if he/she knows of any assistance."
