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.
Some people have had bad side effects from short bouts of inhibiting 5AR with Finasteride, and others only after longterm use (months, years). Each individual's body, genetics and hormone profile is different and thus response/recovery after quitting the medication will be unique to them as well.
