I use both Viagra and T-patches. My insurance subsidy has decreased  as of May 1. I once paid 44 cents for each T-patch; now the price is  83 cents. I once paid $1.67 per Viagra tablet; now I must pay $3.13.  Despite the higher copayments, the amount paid remains a fairly small  fraction of the market price.    Have any others had such increases in prices for these two products?
