Some medicines relieve pain. If you pull a muscle, your doctor might tell you to take ibuprofen or acetaminophen.
These pain relievers , or analgesics, don't get rid of the source of the pain — your muscle will still be pulled. What they do is block the pathways that transmit pain signals from the injured or irritated body part to the brain in other words, they affect the way the brain reads the pain signal so that you don't hurt as much while your body recovers. As people get older, they sometimes develop chronic or long-term conditions. Medicines can help control things like high blood pressure hypertension or high cholesterol.
These drugs don't cure the underlying problem, but they can help prevent some of its body-damaging effects over time. Among the most important medicines are immunizations or vaccines.
These keep people from getting sick in the first place by immunizing, or protecting, the body against some infectious diseases. Vaccines usually contain a small amount of an agent that resembles a specific germ or germs that have been modified or killed.
When someone is vaccinated, it primes the body's immune system to "remember" the germ so it will be able to fight off infection by that germ in the future. Most immunizations that prevent you from catching diseases like measles, whooping cough, and chickenpox are given by injection.
No one thinks shots are fun. But the diseases they prevent can be very serious and cause symptoms that last much longer than the temporary discomfort of the shot. To make life easier, now you can get immunizations at many pharmacies. Although some medicines require a prescription , some are available in stores. You can buy many medicines for pain, fever, cough, or allergies without a prescription.

No matter what type of medicine your doctor prescribes, it's always important to be safe and follow some basic rules:. Taking medicines may feel like a hassle sometimes.
But medicines are the most effective treatments available for many illnesses. If you ever have any questions about what a medicine does or how you should take it, talk with your doctor or a pharmacist.
