CHQ: SUBJECT: taking medications options
  MESSAGE: If my doctor gives prescription for Inderal 40 mg  twice a day,  pharmacist says take 80mg time release once day.  Is it appropriate to follow pharmacists directions rather than doctors prescription 40 mg twice a day.  Does 40 MG twice day equal constant 40 mg,  or does it build to 80 and maintain 80 mg?
Summary: Is Inderal 40 mg  twice a day equivalent to 80mg time release once a day?
