If Only My Thoughts Had Wings

Antibiotics kill some bacteria, but don’t manage to kill other bacteria. Just like when you get a particular sickness (or a vaccination), your body can protect you from future infections, any bacteria that came into contact with the antibiotic is protected from future doses of that antibiotic. Bacteria are very virulent breeders, so they spawn more resistant bacteria.

If you take the full dose of antibiotics, your natural antibodies can deal with the cells that are resistant while the medicine kills off the bacteria that isn’t resistant. If you don’t take the full course of antibiotics, then your body has to deal with both the resistant and the non-resistant strains of bacteria, and it can become overwhelming. Also, most bacteria are able to pass on genes between still-living cells, so that previously non-resistant strains become resistant, and you have inadvertently cultivated a stronger strain of bacteria.

Furthermore, colds and the flu are viral infections, so antibiotics don’t work against them anyway. The best protection against viral infections are vaccinations, as there are not many viruses that we have developed anti-viral medication against, once you already have the disease. If there are anti-viral medications, it is even more important that you take the full dose of the medication, because anti-viral medication is even harsher against the body than antibacterial medication is.
