I take a number of different medications and herbal supplements. Because keeping separate containers in my pocketbook is cumbersome, I've been combining them together in the same prescription bottle. I'm wondering if this alters or diminishes their effectiveness.
The combination includes: regular tablets, some of which have been cut in half; coated tablets; and capsules. The capsules are clear, made of plant-based hypromellose, and are filled with either powdered medication or ground herbs. There are no gel-caps or anything containing liquid.
There's usually some fine powder in the bottom of the bottle, which I assume comes from the broken pills. Other than that, everything appears intact and not misshapen, stuck together, or otherwise compromised.
Is there an overarching rule of thumb for this situation, or would it depend on the specific medications?
