Since pipelines are buried underground, pipeline companies use line markers like those shown to the right. The markers indicate the approximate location of the pipeline. Markers are placed where pipelines intersect streets, railroads, rivers and heavily congested areas.
Finasteride has certain side effects, one of which is erectile dysfunction. Even small amounts of finasteride can cause this side effect. Other medication for an enlarged prostate to minimize urinary frequency include tamsulosin. You can try Flomax or Urotel and see how you respond to these agents which work at the bladder level.
Tamsulosin is more active against the alpha adrenergic nerves of the prostate and bladder neck than these other drugs and has a lesser effect on alpha adrenergic nerves elsewhere in the body. For this reason, tamsulosin causes fewer side effects, especially low blood pressure, than other alpha adrenergic blocking drugs. Moreover, tamsulosin therapy can be started at the optimum dose whereas other alpha adrenergic blocking drugs need to be started at low doses with the doses slowly increased over time in order to minimize the side effects.
