Why should you take tablets with water or milk?

Answer 1

This is not always true. Some pharmaceuticals are formulated with the intention that they NOT be ingested simultaneously with dairy products...

Some drugs are irritating to the stomach lining or duodenum - and a sufficient amount of liquid ingested with the tablet will "buffer" or slow the absorption of the chemicals.

Depends on the tablets.

And as always don't ever, ever let anonymous strangers guide you about potentially life-and-death matters such as medicine.
