In the early 1960s, people called doctors to treat illnesses right at home. These physicians, carrying their iconic black bags, would arrive at patients' doorsteps, ready to serve. But with advancements in medical technology house call doctors all but disappeared.

The famous proverb, "An Ounce of Prevention Is Better Than a Pound of Cure" helps us realize that it is always better to prevent a problem than to apply its solution.

When visiting a doctor seems like a hassle, people often tend to look for cure over the internet, or even use non-prescription medicines to treat symptoms and ailments.

OTC stands for Over-the-counter medications that are readily available at supermarkets, drugstores and convenience stores. Since one does not need a prescription for OTC drugs, it is presumed to be less harmful. The truth, however, is that it's risky to misuse either.
