There is seldom a problem with using generic drugs, and truthfully, I would rather see the drugstore get the profit than the highway-robber drug companies. I prescribed a new antibiotic to a patient last year for a bladder infection. It was the only oral drug available for the bug he had, and the cost for a 10-day course (20 pills) was $2000. The cost of a course of treatment for hepatitis C is $80,000 to $100,000. Sure, insurance will cover it. That’s a big part of why insurance costs so much. In a lot of cases, it feels to me like the drug companies are saying, “Your money or your life.”
The area where problems can crop up is with timed release meds. The active ingredient in the pills is the same but the release mechanism can vary, and isn’t always equivalent.
