ELI5: Most over the counter pills (e.g. ibuprofen) have a recommended dose of at least 2 pills. If this is the case why don’t the medicine companies start producing pills with twice the dosage?

There's a few good reasons:

1. If you only want a half dose, it's easier to take one pill than to cut a pill in half
2. If you want a stronger dose, you can take 3 or 4 (check the drug label first!) and vary the dosage more easily
3. A stronger pill would be larger and harder to swallow.  Many people would rather take 2 small pills than one giant pill.
