Viruses are vastly complex on the molecular level, so they don't metabolise throughout the body like common antibiotics do, and the immune system also poses a big problem. I'm not saying phages aren't worth looking into, but clearly the matter isn't as simple as changing what's in the pill you take.
I work in the healthcare field. Here's the problem, we are testing people for any strain of a Coronavirus. PCR basically takes a sample of your cells and amplifies any DNA to look for 'viral sequences', i.e. bits of non-human DNA that seem to match parts of a known viral genome.

While prescription antibiotics do have their place, it’s not always necessary to use them. Instead, it’s perfectly reasonable to use natural alternatives like manuka honey and garlic (oil).
The Immune System—The Body’s Defense Against Infection. To understand how vaccines work, it helps to first look at how the body fights illness.

When the bacteria do not get the needed nutrients for growth, they would eventually die. Example of this type of antibiotic is the polymyxin B.
Another evidence that antibiotic resistance does not lend support to evolution is that the rise of antibiotic resistance as a result of mutations have been extremely rapid because the mutations need only to reduce or damage the function of pre-existing systems (i.e. reduce protein binding effectiveness, damage cell transport systems, or disrupt ...

Antibiotics work in different ways. For example, penicillin works by indirectly causing the bacterium's cell wall to weaken and burst, so it dies. Tetracyclines, on the other hand, do not kill bacteria but inhibit their growth by stopping the bacteria from making proteins.
