Stimulants are drugs that stimulate the central nervous system into working faster. Taking these
drugs makes the heart beat faster. Your blood pressure goes higher and it makes it hard for you to
go to sleep. The body is so busy that it sometimes makes you forget to feel hungry. These drugs
include caffeine, nicotine, amphetamines, cocaine, ecstasy, and others.
Depressants are drugs that have opposite effect to stimulants. They slow down the central nervous
system. This make your heart beat slower, breathing gets slower, blood pressure goes down, and
the body may feel relaxed. These drugs include alcohol, tranquilizers, inhalants, and solvents (like
glue).
Self-medication
There are times when a person, out of desperation, would resort to self-medication. It refers to the
treatment of common health problems with medicines especially designed and labeled for use
without medical supervision and approved as safe and effective for such use.
Medicines for self-medication are often called nonprescription or over-the-counter (OTC) and are
available without a doctor’s prescription through pharmacies. In some countries like the
Philippines, OTC products are also available in supermarkets and other outlets.
Every day, everywhere, consumers reach for self-care products to help them through their common
health problems. They do so because it may be easier for them, it may be more cost or time
efficient, they may not feel their situation merits making an appointment with a healthcare
professional, or they may have few or no other options. The challenge and opportunity for
governments, healthcare professionals, and providers of self-medication products, then, is to have
a responsible framework in place for self-medication.
There is evidence that consumers can and do practice self- medication responsibly. There Is also
support showing that consumers recognize and respect nonprescription medicines. As a whole,
they use them appropriately, carefully, and safely; and they read nonprescription drug labeling.
Studies show that people are typically cautious and careful when they do turn to nonprescription
medicines. They read labels and they generally take products for less than the maximum period of
time indicated on the label.
