Propecia and liver enzymes

Has anyone had a raised bellirubin while taking Propecia? I recently had a blood test that showed a slightly raised bellirubin and now I am concerned about taking propecia. I was thinking of reducing the 1mg to 0.5mg. I have been on it for a year and wondered if .05 will be effective. I also noticed that the topical is available in Canada. Has there been much success with the topical? And does anyone know of a doctor out there that will write prescriptions for it in the US?
