Many new technology and researches is done on redefining the drugs , so we are getting a wide range of drugs, due to which, both over the pharmacy counter and by prescription from a physician, a wide range of illnesses and disorders can be controlled, relieved, or even cured.

 Many diseases can be controlled such as hypertension, eliminate the irritating effects of allergies, hay fever, relieve cold discomfort, cure a variety of stomach and intestinal disorders, control stress and insomnia, and end bacterial and fungal infections-all by taking a medication.

Modern drug therapy has given many benefits, but there are many responsibilities. There is a great deal that the patient has to know about the medicine he is taking: how to take it, and how often , what its possible side effects are, and how it might react with other medications, foods, or alcohol.
All this process takes place, when your doctor writes out a prescription.

The choice of drug is determined by many facts , including information about drugs that you have taken at various times in your life, any allergic reactions you might have suffered, any chronic conditions for which you are still taking medication, any special side effects that you have experienced with certain drugs or classes of drugs, and any chronic health problems you have. Based on it, the doctor makes a decision about the right drug for your particular condition.

You should be aware of the facts, before you take your first dose of pill or swallow your first spoonful of medicine and how to administer it. You need to understand the dosage schedule-how often to take the drug, each time, whether to schedule medication at night as well as in the daytime.

You need to know something about common side effects to distinguish between those that are truly "minor side effects" and those that are signs of a serious drug reaction. You must know whether you should continue the medicine after your symptoms have completely disappeared, or whether you should stop the medication when you no longer show, symptoms.

You must know if the drug might interact negatively with other drugs you are taking even nonprescription drugs, such as cold pills, aspirin, or vitamins, with alcohol, with caffeine, with foods, and, if you are a woman, with the form of birth control that you use. You should be responsible for taking your prescription drugs I.e. over and under dosage.

It becomes a practice after reading a common drug, used very frequently so as you read on, you will learn how some common types of drugs work to relieve certain conditions or symptom and how to read a prescription correctly and how to buy, store, and use drugs; to administer the most common forms of medication to yourself or to someone else; to save money, in many cases, by substituting a less expensive generic drug for a more expensive brand-name medication.

Finally, you will learn to identify some common, side effects of the most widely used prescription drugs recognizing symptoms that will help you decide when your drug response is not a cause for concern and when it calls for prompt medical attention.

You should also ask your doctor or pharmacist for the latest information about your medications; although every effort has been made to ensure that the information here is up to-date, new developments occur rapidly in drug research.
