Both men and women should have their first colonoscopy by age 50, unless there are reasons for your healthcare provider to recommend one sooner. These reasons may include a family history of colon cancer or colon polyps, a personal history of inflammatory bowel disease, or certain gastrointestinal (GI) issues.
Schedule III and IV medications (such as Vicodin and Xanax) are often valid for 180 days, while prescriptions for Schedule V and VI drugs (sleep aids and anti-diarrheal medications) may be good for up to 12 months due to their lower risk for dependency.
My specific question that I can't seem to figure out, just from knowing of this existing 7 day regulation, is about what counts as the start of 30 days for my last prescription, to figure out if I will be able to fill it the day I get the prescription written.
