Charger,
Insurance will help with Cialis, because it is indicated for "symptoms of" BPH. Viagra is to short-lived and the spike is outside the therapeutic range for BPH "growth" (my opinion on the difference of wording, hence the quotations). A decent GP will be able to do this for you. The medical community accepts the hereditary relationship with Bp issues (these are blood pressure drugs-vasodilators). Just work from that conceptual when you talk to your doc. BTW, it is approved for this use but insurance companies don't like to think they are going to have to cover it for the res of your life.
