Septic tanks use beneficial bacteria to break down these large solids that go into the septic tank and turn them solid. If you let medicines down your drain or toilet, these anti-bacterial drugs can kill these beneficial bacteria, causing them to work slowly. 

So if these drugs keep killing the beneficial bacteria, you need to clean your septic tank more often. So if you are unsure what to do with your medicines after taking them, you can either return the remainder to the pharmacist or store them away in your room. 

Flushable products
